Ran into this problem when first tried. Unfortunately it is contingent on the phone having simultaneously PD and OTG enabled at a hardware level. It does work with the newer style usb c splitters but the phone has to have it hardware wise. The other unfortunate thing is that this spec is not easily found, at least I couldn't. So it's a trial and error thing. Higher end devices 2018 foward tend to have it. But I'm sure there are lower ones too.
@Christopher Easler but something interesting, i have the same phone and with hml adapter for hdmi use, everything works and charges perfectly! i thing it is in the kernel of the phone. May be a custom rom will solve the problem.

I ran octa4a 1.0.4 for awhile with no issue until octoprint 1.8 release. The octa4a 1.1.1 solved this problem. Great informative octoprint video as always. Looking forward to an updated Linux revisit 🤙🏼
This is perfect! Here in Sweden it's reasonable easy to get hold of Raspberry Pis last I looked, but I want one to tinker with and not tie it up to the printer. And now all I need is to fire up one of my old Androids - brilliant! Shouldn't be that hard to just scrap a USB cable to make a splitter for free.
Try using the camera in landscape mode...i.e. rotate the phone. When I do this, I don't need to flip or rotate at all!...I think this is the prefered orientation, since it gives you the wider view of the print bed. Great content - I am REALLY liking this years series so far! Didn't have issues on the 1.04, but am going to upgrate to the 1.1.1 varsion (already went to the 1.8.1 version of Octoprint
The one that I was awaiting from your channel! 1) Be careful of the battery. Specially if it is a swollen battery. Connecting it to the charge for long times could be risky. I usually just pull off the battery IC and then provide 4.0 V to it in the place of the battery 2) I had a lot of problems with Octolapse and older Android versions, I can't make it work, with newer versions I can with no problems. 3) For some reason I've never found a proper OTG cable to charge and connect the printer at the same time.
This was a really great video, Chris, thanks so much! I am trying to link up a small ~10 printer farm, so I'm exploring this option and with intention to aggregate instances using OctoFarm. I'm also running into the same issue with simultaneous charging and OTG functionality - would love an update on this! If I can't get charge + OTG on an old Android, I'll explore using a more powerful computer than a Pi (and containerizing) or using Repetier-Host.
The trick is getting a phone/tablet that will allow OTG & Charging at the same time. I went and did an experiment with a cheap Amazon Fire tablet. Octoprint runs brilliantly on it, however, it won't charge and provide otg at the same time. I also tried running octo4a on an Andriod TV box, (onn) from Walmart that was 20 bucks. it will install, and run but only for a few seconds before itself kills itself. boo. The next test is an RCA Tablet that runs USB C, my goal is to find a Super Cheap tablet that will blow a raspberry pi out of the watter and get it to run klipper.
@@ChrisRiley Thanks! I haven’t been able to install octoprint on either device yet, sadly. It’s saying the install is corrupted and I’ve been digging into the Python scripts and GitHub issues.

Hi Chris, another option for octoprint, klipper or anything in linux is a Android TV box, very inexpensive and are a very good option. They do involve a bit of programming depending the chip the box uses. There is not a lot of information on setup, might be a good topic to look into seeing Pi's are rare now, and TV boxes are plenty.
Cannot attach an accelerometer is a big downside. You can get a Pi3 alternative for $less than 60usd. Less hassle. But using the phone as a screen is a good idea. Also very disappointed a video installing klipper was never made for octo4a, although it was baited at the start of the video
Great idea and I'm hoping to implement it someday, but the first OTG + Power cable, actually the 2 pack Amazon sent were complete duds. I tried them on 1 phone and 2 tablets, trying 3 different USB power supplies and 2 different micro USB wires and neither of them passed power through to the phone (or tablet). I have a feeling the most challenging part of getting this going will be wading through the glut of cheap USB OTG + Power adapters on Amazon to finally find one that works.
@@ChrisRiley My guess is that it did not work. MOST vintage android devices WILL not work. octo4a is a great exercise but unusable for longer that the battery lasts.
Hi Chris, great video! Helped me out a lot. I set up my old OnePlus 9 Pro and am using its camera to monitor my prints. Is there anyway I can lock focus on the print head? My phone seems to keep switching focus between the print head and the back of the printer.
Thank you! That's a great question, I don't thing octo4a has any smarts on how the camera does the focus. You might be able to go into the phone settings and turn off the auto focus.
Great video! Thanks for explaining everything clearly. I have 1 question for you. What can I do if the webcam url is unreachable? How do I verify what it should be and correct it?
That's a good question. It still runs MJPEG streamer, so you could check it by looking at the service. Check it with ps -aux |grep mjpeg it should list the port.
Since I have an oldschool Ender 3 with a mini usb connection, I had to get a little creative. I ordered a usb c to mini usb adapter (female to male). Then bought a usbc hub. All that is supposed to be here Thursday. Here's to hoping that adapter doesnt fry my printer. Honestly I was just looking for a video on how to use an old phone as a webcam for octoprint. Wasn't really planning on using it as a server as I already have an octoprint server up and running.
Thanks Chris! Again great video! Thank you. Question...have you attempted to run the Octodash for the android to get the screen visuals? Is that possible? Note: Here is some info for the ones that are curious. I have a work around for the Y cable. First of all, I know that leaving a battery plugged in constantly is bad for it and dangerous for lithium so what I done was removed the battery completely from my phone, most batteries will be labeled + and - on 2 pins only. I took a 5v AC to DC adapter and soldered the positive and negative directly to those matching pins. I now can plug my phone up and leave it running constantly with no worries about a battery and this leaves my Data port open to work with the printer. No need for any y cables etc. I hope this helps someone.
Thanks! I haven't tried in incorporate Octodash on this setup yet. Not completely sure how it would work. Thanks for all the great info on how to deal with the charging, this should help other folks.
Yeah it's the actual phones auto rotate settings in notification pull down menu lock it to portrait or landscape so when when moving the phone the camera stays locked in that orientation
so im running into an issue where Octoprint 4a is installed it gives me the IP to connect and the port. when I go to my computer that is on the same network as my phone that is using my home's wifi connection it will not connect. I tried going to the phone and browsing to localhost:5000 and it goes to octoprint just fine. I also went to my router and set my phone's MAC to get a static IP that it says it is using in octoprint as well as in my phone's wifi information and my router's list of IPs. What am I missing?
The only thing I can think of is that your phone won't allow an incoming connection. I would look into your wifi settings on the phone, maybe there is a mini firewall of some kind.
This doesn't work for me at all. The phone is a MOTO G7 Power running Android 10. I'm getting "Installation Corrupted". I attempted to SSH into the phone, but I'm getting "Connection timed out". The only other App I've installed on this phone is AlfredCam (which has been working fine for months). I also tried to install Octo4A on my (identical) daily use phone, but on that phone I'm getting "Octoprint For Android keeps stopping" as soon as I hit "Install Octoprint".
The lack of Raspberry Pi has been a real issue. Have to be very judicious, atm. Nice video. Wonder if the COto4 instance would work for a farm set up. Might have to research that.
I've tried to find one that will do both. It really depends on the phone you use. I have had some luck with this one, but it's pricey for a gamble. amzn.to/4dggrkG (aff link take you to Amazon)
Quickly scanned the comments and didn't see my question. Sorry if it's a duplicate...' Can you run two printers from one phone? Not needing two cameras, but would this require two phones? Thanks, Chris.
I have been using the legacy app for a year or so now. Octoprint recently went to python 3 been lazy and haven't printed anything. Went to update my android server and couldn't find on Google play. This screen is def the same app from what it looks this makes sense I couldn't get octoprint server to update kept getting errors so might try this see if it will update. Pair with another octoprint app for the phone you use and wow I have been amazed. Set on the couch print watch the live feed from server phone awesome. Will try new app soon. Stay creative Peep's 😉
Did you do the Klipper on phone video? I got it set up, but not sure how to use it since I can't get Mainsail loaded? But thr Klipper plugin is installed. How do you use klipper without mainsail/fluidd?
Creality Ender 3 Max and mine will nevert recognize the printer, even when the Android phone is plugged in directly to it. 'No working connection parameters could be found'. Been fighting with this for 2 days now. uchhh......
An OTG cable is must for connection or its just for charging purpose? Im trying to connect pixel phone via direct usb C cable that came with the phone and octo4a is not detecting the printer.
@@ChrisRiley Figured out! So I tried Type C to C data cables and it didn't connect. Then I tried never used cable that came with my pixel buds that had USB C to USB A and it worked! I used a OTG converter that came with phone to connect USB A to USB C on my phone. Thanks

Hi, when I connect the mobile to the printer, the board has power all the time, how do you fix this? Also when I connect the mobile to the printer bevor powering the printer, the homing is shit, it runs to the end stops like hell and fault.
My phone won't charge even without an OTG cable. I'm trying to run this on a Samsung s10e. Haven't gotten the OTG cable yet to try hooking up to the printer, but I've been really enjoying the camera server with it's ability to focus up close and stabilize the image. I was even able to add it to my Blue Iris camera server. Problem is that it is not charging when Octo4 is running. It's not hooked up to the printer, I've even stopped the print server and just was using the camera server, turned down to 720p 5fps and it's still rapidly draining the battery. I even hooked it up to a quick charger and the phone says it's connected to a "fast charger", but the battery keeps draining anyway. Phone is getting really hot too and making me nervous about the battery. Once the battery drains out and it shuts down, the phone cools off and it charges back up just fine. Not sure what's going on here. I've never felt this phone get so hot. Being a s10e I would think it could handle this app with ease. I'm not using any OTG cable yet, just directly plugged into the charger.
Wow, that is really strange, I wonder what is going on as well. I would like to find someone else with the same phone and see if they have the same issue. I would check over on the octo4a github.
Hi there ... cool , it's an old topic , the version is not the same ... but small question , how to know the phone performance needed to run manage multiple printers in the same instance of Octoprint ?
That's a great question and with a phone that is really hard to tell. All you can do is just give it a try. I'm sure someone out there has a performance monitor for phones, but I'm not familiar enough with them to know.
@@ChrisRiley I think that's kinda funny because I think I ran in to a similar problem as you. I couldn't find a good OTG cable for micro usb have you considered usb type-c to micro usb adapter ? since most devices don't use micro usb anymore there's not that many up-to-date type of hub/ otg cable that adapter could at least open the door to a more modern OTG cable.
I'm guessing this is because of the changes that were made to octoprint. I would ask over on the octo4a github to see if they plan on updating as well.
Fantastic video. Looks like some really kool code. Looking forward to trying it. Does it set up a real root access or is it in a sandbox and does it set up a host name, so I can access it via a hostname vs an ip address or localhost. Thanks Chris
Is there an app other than octoprint that simply works as an IP camera and does time lapse? I am just doing timelaps now with some app but can't view the stream over WiFi. If no IP camera is there another timelaps app for Android that can set the focus to manual? I am using superlapse right now but it is focus hunting all the time when the printer moves....and there is a lot of movement going on in my delta.
hi chris. do i get this right? i need all the time internetconnection? my printer is in the workshop, but when i am there i use the internet for my phone. is it still possible to check the print from home, whithout having a internet connection at the mobile in the workshop??
When I try and access the octopint through my home computer, i get the "This site can not be reached" message. Octo has the right IP given by the router
It should just come up if you punch in the IP with the port, like this 192.168.1.x:5000 unless your phone has some sort of security that blocks the connection.
Hi; im trying to install this software in a S7 Edge, and it keeps bombing out while installing dependencies . Warning could not build wheel for tornado that uses pep 517 Can you please tell me what can be wrong?

You cant flip any camera in OctoPrint except the Raspberry Camera. My current USB camera cannot be rotated on my Raspberry Pi 4 with OctoPrint. But my raspberry pi camera connected via the ribbon cable does rotate.
Hi Chris, great video. I have a Samsung Galaxy S5 and can't get it to charge and connect to the printer at the same time. I'm going to buy the adapter you linked, but I noticed that your phone in the video is not charging during the tutorial. The battery drops from 100% to 60%. Does your adapter actually work? The Amazon listing says it does not charge the phone. Hoping you can sort this out. Thanks!
Awesome! Thanks for testing! What you could try out: put a small USB hub between the adapter cable and the printer. You could connect a keyboard as well as a mouse, and use them on the phone. Also you should be able to connect your palette 2. Do you think it is possible to install a second instance of octoprint like on a pie, to control a second printer?
@@ChrisRiley just watched you vid on 2022 windows to run octoprint. Reason. Im sick of powercuts/accidental shutdowns corrupting the octoprints sd card on a pi. Thought octo4a was going to be my saviour but alas its not great on any phone i have access to.
Hii Chris, Thank you for making such useful videos, they all helped us a lot. A que came in my mind that can we use TMC2209 stepper drivers of another board with some different board ?? For e.g. can i use Lerdge TMC2209 stepper drivers on BTT Octopus Pro V1.0 Board ??
Yes, you should be able to use them on any board, if they have a pinout, look it over and make sure it matched the board you are going to, but most of them are pretty close to one another.
@@ChrisRiley I have one more que, i"am using BTT TFT70 v3.0 GD display with BTT octopus pro V1.0. I want to use it in Vertical Mode, but after the screen get vertical, the touch doesn't work and also the icons are not appear at right place. i have done all the possible methods whatever i found on internet. Please Help me or suggest me anything regarding this.
Hey Chris I was wondering how the follow up video is coming along and I did basically everything in this video on my s7 but I can’t seem to get the y splitter to charge and run the printer at the same time is there a specific rom or something you have on that device?
MicroUSB will not charge the phone wilst in OTG mode. It's designed to power the peripheral not the phone and I'm affraid it's a limitation (hardware) of the microUSB design. USB C will work though as it is designed to work both ways. Wireless charging might work whilst printing?
Hey Chris, Great Video! IT is a great way to repurpose an old android device. Especially with the ever growing pi shortage! What was the setup you used to hold the phone?
I don't know what he used, but we are watching this because we have a 3D printer so... ... just design and make one 😁 I'm sure there already are several variants on printables, thingiverse, etc.

Did you experience anything like this or can advise what ROM/version of Octo4A works on your S5? Thanks!
Mine was pretty solid on my S5, but that was a little older version of Octo4A. Not sure about the newest one. I stopped pursuing the S5 because I can't find a cable that will allow USB and charging consistently. Have you found one?
@@ChrisRiley I didn't no, but I happened to buy the special back for my S5 that allows wireless charging many years ago so I can leave mine in a wireless charging cradle. I did also find this video that claims you can get your split OTG cable working properly with a single resistor, but I've not attempted it myself.

I tried them on 1 phone and 2 tablets, trying 3 different USB power supplies and 2 different micro USB wires and neither of them passed power through to the phone (or tablet).
I have a feeling the most challenging part of getting this going will be wading through the glut of cheap USB OTG + Power adapters on Amazon to finally find one that works.
I have another type of cable on order, I will report back if the new version works.
@@ChrisRiley My guess is that it did not work. MOST vintage android devices WILL not work. octo4a is a great exercise but unusable for longer that the battery lasts.
Hi Chris, great video! Helped me out a lot. I set up my old OnePlus 9 Pro and am using its camera to monitor my prints. Is there anyway I can lock focus on the print head? My phone seems to keep switching focus between the print head and the back of the printer.
Thank you! That's a great question, I don't thing octo4a has any smarts on how the camera does the focus. You might be able to go into the phone settings and turn off the auto focus.
Great video! Thanks for explaining everything clearly. I have 1 question for you. What can I do if the webcam url is unreachable? How do I verify what it should be and correct it?
That's a good question. It still runs MJPEG streamer, so you could check it by looking at the service. Check it with ps -aux |grep mjpeg it should list the port.
Since I have an oldschool Ender 3 with a mini usb connection, I had to get a little creative. I ordered a usb c to mini usb adapter (female to male). Then bought a usbc hub. All that is supposed to be here Thursday. Here's to hoping that adapter doesnt fry my printer.
Honestly I was just looking for a video on how to use an old phone as a webcam for octoprint. Wasn't really planning on using it as a server as I already have an octoprint server up and running.
Way to think out of the box! Good luck
Thanks Chris! Again great video! Thank you. Question...have you attempted to run the Octodash for the android to get the screen visuals? Is that possible? Note: Here is some info for the ones that are curious. I have a work around for the Y cable. First of all, I know that leaving a battery plugged in constantly is bad for it and dangerous for lithium so what I done was removed the battery completely from my phone, most batteries will be labeled + and - on 2 pins only. I took a 5v AC to DC adapter and soldered the positive and negative directly to those matching pins. I now can plug my phone up and leave it running constantly with no worries about a battery and this leaves my Data port open to work with the printer. No need for any y cables etc. I hope this helps someone.
Thanks! I haven't tried in incorporate Octodash on this setup yet. Not completely sure how it would work. Thanks for all the great info on how to deal with the charging, this should help other folks.
it helpped me, i just soldered wires strait to phone. great idea.
Thanks bro! Ima do this now but I'm confused on 1 thing. You went from 100% phone install to your pc, why for what, how?
Yeah it's the actual phones auto rotate settings in notification pull down menu lock it to portrait or landscape so when when moving the phone the camera stays locked in that orientation
😀👍
Any update on the cable for Samsung S5? I have the same phone but won't charge at the same time.
I never found a cable that worked. ☹
so im running into an issue where Octoprint 4a is installed it gives me the IP to connect and the port. when I go to my computer that is on the same network as my phone that is using my home's wifi connection it will not connect. I tried going to the phone and browsing to localhost:5000 and it goes to octoprint just fine. I also went to my router and set my phone's MAC to get a static IP that it says it is using in octoprint as well as in my phone's wifi information and my router's list of IPs.
What am I missing?
The only thing I can think of is that your phone won't allow an incoming connection. I would look into your wifi settings on the phone, maybe there is a mini firewall of some kind.
This doesn't work for me at all. The phone is a MOTO G7 Power running Android 10. I'm getting "Installation Corrupted". I attempted to SSH into the phone, but I'm getting "Connection timed out". The only other App I've installed on this phone is AlfredCam (which has been working fine for months). I also tried to install Octo4A on my (identical) daily use phone, but on that phone I'm getting "Octoprint For Android keeps stopping" as soon as I hit "Install Octoprint".
There have been a lot of issues reported with this project recently. I am hoping they get it fixed soon and published.
The lack of Raspberry Pi has been a real issue. Have to be very judicious, atm. Nice video. Wonder if the COto4 instance would work for a farm set up. Might have to research that.
That's a good idea, thanks
I have the Y cable and it either charges or datas transfer use. Anyone have idea that what could be the issue? Should I buy a different adapter?
I've tried to find one that will do both. It really depends on the phone you use. I have had some luck with this one, but it's pricey for a gamble. amzn.to/4dggrkG (aff link take you to Amazon)
Quickly scanned the comments and didn't see my question. Sorry if it's a duplicate...'
Can you run two printers from one phone? Not needing two cameras, but would this require two phones? Thanks, Chris.
I think you could, but it's probably not going to be that easy. Octo4a is really designed for one for one.
@@ChrisRiley thanks!
I have been using the legacy app for a year or so now. Octoprint recently went to python 3 been lazy and haven't printed anything. Went to update my android server and couldn't find on Google play. This screen is def the same app from what it looks this makes sense I couldn't get octoprint server to update kept getting errors so might try this see if it will update. Pair with another octoprint app for the phone you use and wow I have been amazed. Set on the couch print watch the live feed from server phone awesome. Will try new app soon. Stay creative Peep's 😉
Awesome! thanks
Did you do the Klipper on phone video? I got it set up, but not sure how to use it since I can't get Mainsail loaded? But thr Klipper plugin is installed. How do you use klipper without mainsail/fluidd?
You can do it through the octoprint plugin, but I still haven't tested klipper with octo4a, I will make it a priority.
@@ChrisRiley Thanks Chris, It is a very interesting option if you can't get a pi. You get touchscreen and wifi essentially free:-)
Creality Ender 3 Max and mine will nevert recognize the printer, even when the Android phone is plugged in directly to it. 'No working connection parameters could be found'.
Been fighting with this for 2 days now.
uchhh......
If you cable the printer up to a computer, will it see it?
Had the same issue for Ender 3 V2 Neo. I was using a USB cable that was for charging only. Have you made sure your USB cable is a data cable?
Has anyone tried this on an Amazon Fire HD8 yet? It seems to load ok. Thanks for a great tutorial Chris!
Thanks for watching!
This is great!!
Thanks Chris
Thank you
Could you connect power straight to the battery contacts and just forget the USB charging?
Honestly,. I'm not sure if that would throw the phone off or not. Might be worth a try.
can't wait for klipper and hopefully Fluid and Mainsail follows suite.
Thanks for watching, stay tuned
An OTG cable is must for connection or its just for charging purpose? Im trying to connect pixel phone via direct usb C cable that came with the phone and octo4a is not detecting the printer.
I don't think you should need a OTG to connect to the printer. It could be a permissions issue on the phone no letting it connect.
@@ChrisRiley Figured out! So I tried Type C to C data cables and it didn't connect. Then I tried never used cable that came with my pixel buds that had USB C to USB A and it worked! I used a OTG converter that came with phone to connect USB A to USB C on my phone. Thanks

You can remove the app from your phone and try again. Only other option would need you to login to the terminal ssh to reset it. ruclips.net/video/12m77CHspEI/видео.html
@@ChrisRiley when I reinstalled the app the IP didn't change, so I wasn't prompted to do the wizard again :/
Hi, when I connect the mobile to the printer, the board has power all the time, how do you fix this? Also when I connect the mobile to the printer bevor powering the printer, the homing is shit, it runs to the end stops like hell and fault.
The board has power all the time, I'm not sure what you mean.
@@ChrisRiley as long as I connect the mobile phone to the board via USB it is under power 24/7. I don't like that.
@@martinwirtz577 Ah, so it depends on the board. Some of them have a vrf jumper that you can set to keep this from happening.

My phone won't charge even without an OTG cable. I'm trying to run this on a Samsung s10e. Haven't gotten the OTG cable yet to try hooking up to the printer, but I've been really enjoying the camera server with it's ability to focus up close and stabilize the image. I was even able to add it to my Blue Iris camera server.
Problem is that it is not charging when Octo4 is running. It's not hooked up to the printer, I've even stopped the print server and just was using the camera server, turned down to 720p 5fps and it's still rapidly draining the battery. I even hooked it up to a quick charger and the phone says it's connected to a "fast charger", but the battery keeps draining anyway. Phone is getting really hot too and making me nervous about the battery. Once the battery drains out and it shuts down, the phone cools off and it charges back up just fine. Not sure what's going on here. I've never felt this phone get so hot. Being a s10e I would think it could handle this app with ease. I'm not using any OTG cable yet, just directly plugged into the charger.
Wow, that is really strange, I wonder what is going on as well. I would like to find someone else with the same phone and see if they have the same issue. I would check over on the octo4a github.
I’m getting the “installation corrupted” thing instead of “octoprint is running”… what do I do?
I've seen a lot of errors reported with the newest version. I hope they get it fixed and updated soon.
Hi there ... cool , it's an old topic , the version is not the same ... but small question , how to know the phone performance needed to run manage multiple printers in the same instance of Octoprint ?
That's a great question and with a phone that is really hard to tell. All you can do is just give it a try. I'm sure someone out there has a performance monitor for phones, but I'm not familiar enough with them to know.
@@ChrisRiley ok thanks for replying ;)
Thank you Chris for the awesome video, did you have any luck so far with setting up klipper ?
Not yet, still trying to find a better OTG cable.
@@ChrisRiley I think that's kinda funny because I think I ran in to a similar problem as you. I couldn't find a good OTG cable for micro usb have you considered usb type-c to micro usb adapter ? since most devices don't use micro usb anymore there's not that many up-to-date type of hub/ otg cable that adapter could at least open the door to a more modern OTG cable.
please help i cannot see webcam on octoprint.Can you make a video fixing the camera ?
I'm guessing this is because of the changes that were made to octoprint. I would ask over on the octo4a github to see if they plan on updating as well.
Has anyone tried using this app on android tv box? If so how did it go?
Thanks for your comment. Let us know if anyone tries it. I'll look into it too
Fantastic video. Looks like some really kool code. Looking forward to trying it. Does it set up a real root access or is it in a sandbox and does it set up a host name, so I can access it via a hostname vs an ip address or localhost. Thanks Chris
I will have to check that, I think it's just sandbox mode. I didn't see a hostname entry, but I think we could add one really easy.
Is there an app other than octoprint that simply works as an IP camera and does time lapse?
I am just doing timelaps now with some app but can't view the stream over WiFi.
If no IP camera is there another timelaps app for Android that can set the focus to manual? I am using superlapse right now but it is focus hunting all the time when the printer moves....and there is a lot of movement going on in my delta.
The only app I have ever used on my Android was hyperlapse, I think it was only on Samsung phones maybe. I don't know about anything else.
hi chris.
do i get this right? i need all the time internetconnection? my printer is in the workshop, but when i am there i use the internet for my phone. is it still possible to check the print from home, whithout having a internet connection at the mobile in the workshop??
You don't need internet, but you would have to have network connectivity. So it still has to be able to reach your network.
And you can access the octoprint from your laptop or other phone just like you do with a pi??
Yes, just use the 5000 port number after the ip.
Let's hope Klipper (Mainsail/Fluidd would be awesome) behaves nicely.
We'll see
When I try and access the octopint through my home computer, i get the "This site can not be reached" message. Octo has the right IP given by the router
Are you using port 5000 on your URL?
Does Octo4A support controlling external devices [via usb maybe?] similar to using Octopi via GPIO ports? 🤞😬🤞
Not that I know of, but you never know who's going to come up with what.
Is the phone screen on or off when using this with timelapse? Screen on drains battery fast.
It has to stay on I believe. I have found some phones/chargers can stay charged while the screen is always on and others cannot.
This is the best way they are $28 dollar android phone u can buy on amazon i been using this for months the best solution and easiest
That's great, thanks for watching
Hello, it works perfect and I installed octolapse, but how do I activate "custom image preferences"?
please help me
I'm not sure, it should work just like the install on the Pi.
hey brother how do i get my screen to come up on my computer from my phone ? its not working thanks in advance
It should just come up if you punch in the IP with the port, like this 192.168.1.x:5000 unless your phone has some sort of security that blocks the connection.
So wait can I only connect to the phone with a desktop/computer?
You can connect from any device on the network.
Hi; im trying to install this software in a S7 Edge, and it keeps bombing out while installing dependencies .

Does Micro USB vs Type C affects print quality in some way? Being the first technically slower than the second
It shouldn't, both are more than fast enough for any amount of gcode streaming.
Prusaslicer?
Great vid, thank you! Does Prusaslicer work with this octo4a directly? Anyone made it happen?
Yes, Prusa slicer will send files to octoprint directly even using octo4a.
Maybe try the a7to rotate in phones pull-down notifications this happens with me on other apps but when switch auto rotate portrait or landscape it'll change it on remote device screen
I'll give that a try.
You cant flip any camera in OctoPrint except the Raspberry Camera. My current USB camera cannot be rotated on my Raspberry Pi 4 with OctoPrint. But my raspberry pi camera connected via the ribbon cable does rotate.
Great, thank you!
Looking at that camera rotation - does flip horizontally & rotate 90 anticlockwise get it to the right orientation?
I think it may also be different depending on the phone you're using.
I'll give it a try, thank you
Hi Chris, great video. I have a Samsung Galaxy S5 and can't get it to charge and connect to the printer at the same time. I'm going to buy the adapter you linked, but I noticed that your phone in the video is not charging during the tutorial. The battery drops from 100% to 60%. Does your adapter actually work? The Amazon listing says it does not charge the phone. Hoping you can sort this out. Thanks!
I thought it was charging, I will go check again.
I have another type of cable on order, I will report back if the new version works.
@@ChrisRiley thanks very much! I really want to be able to use the phone for this. Looking forward to your update.
@@ChrisRiley please let us know what cable you find…
Awesome! Thanks for testing!
What you could try out: put a small USB hub between the adapter cable and the printer. You could connect a keyboard as well as a mouse, and use them on the phone.
Also you should be able to connect your palette 2.
Do you think it is possible to install a second instance of octoprint like on a pie, to control a second printer?
Interesting, I will have to try somethings. I don't see why you couldn't run more than one. I will play around with it.
I connected my microwave and a washing machine to my phone and it works perfectly
I tried this on an lg g5 but it didnt manage to run any successful prints. I may try to acquire a samsung galaxy s6
I have to use my S8 to get charging and connection to work correctly. I am trying to locate more phones to test currently.
@@ChrisRiley just watched you vid on 2022 windows to run octoprint. Reason. Im sick of powercuts/accidental shutdowns corrupting the octoprints sd card on a pi. Thought octo4a was going to be my saviour but alas its not great on any phone i have access to.
Hii Chris, Thank you for making such useful videos, they all helped us a lot. A que came in my mind that can we use TMC2209 stepper drivers of another board with some different board ?? For e.g. can i use Lerdge TMC2209 stepper drivers on BTT Octopus Pro V1.0 Board ??
Yes, you should be able to use them on any board, if they have a pinout, look it over and make sure it matched the board you are going to, but most of them are pretty close to one another.

Hey Chris I was wondering how the follow up video is coming along and I did basically everything in this video on my s7 but I can’t seem to get the y splitter to charge and run the printer at the same time is there a specific rom or something you have on that device?
I've been having the same problem. I haven't been able to figure it out yet.
Hi Chris, do you have a link for the spliter, I've tried a couple but they won't charge my phone. I will also be using the S5.
I'm still having a hard time with this. I need to get more phones to test. It's looking like only some USB-C phones can change while printing.
MicroUSB will not charge the phone wilst in OTG mode. It's designed to power the peripheral not the phone and I'm affraid it's a limitation (hardware) of the microUSB design. USB C will work though as it is designed to work both ways. Wireless charging might work whilst printing?
pudieron encontrar una solución para cargar y transmitir datos al mismo tiempo?
It seems to depend on what phone you use. Some OTG ports allow you to charge and read data at the same time, others don't.
Hey Chris, Great Video! IT is a great way to repurpose an old android device. Especially with the ever growing pi shortage!
What was the setup you used to hold the phone?
I don't know what he used, but we are watching this because we have a 3D printer so...
... just design and make one 😁

Did you experience anything like this or can advise what ROM/version of Octo4A works on your S5?
Thanks!
Mine was pretty solid on my S5, but that was a little older version of Octo4A. Not sure about the newest one. I stopped pursuing the S5 because I can't find a cable that will allow USB and charging consistently. Have you found one?
@@ChrisRiley I didn't no, but I happened to buy the special back for my S5 that allows wireless charging many years ago so I can leave mine in a wireless charging cradle.
