Your troubleshooting steps are pretty much what I use in an industrial maintenance position. In fact, it was tinkering and working on my first 3D printer, an Anet A8, that inspired me to learn more about how machines work and pursue a degree in mechatronics technology which led to me now being an industrial maintenance technician.
@@3DPrintingNerd You're awesome too, Joel! Your videos gave me a lot of inspiration to keep working on things and even led me to finding my favorite filament brand, Protopasta! Guys like you make the community great and I hope you keep your boundless positivity!
In his interview with CNC Kitchen, the CEO of Bambu Lab Dr Tao said that they made the special transparent versions while the injection moulds were brand-new, before they got "punished", which I think means the brand-new moulds are necessary to get a good surface finish for the transparency. He also said that transparent plastics are more brittle, which is tricky for a 3D printer because the plastic has to withstand a certain amount of stress.
As far as injection moulded transparent abs, it's so brittle, sadly it's used more often in speed cubes(rubiks cubes made for solving fast) and it causes so many issues.
Nicely done, and an excellent video! I like that instead of focusing on the OPTICS, you communicated your steps and thought processes in a CRYSTAL CLEAR manner.
You, sir, are hands down the best teacher of 3D printing I've come across on RUclips. Seriously. You have a unique way of presenting detailed information in an interesting and enjoyable manner. Thank you for sharing your experience with us.
You are really onto something Joel, interesting how the preproduction models had the transparent case. I always was fascinated by clear cases, mostly because it was interesting to see the insides of the (video game console, or whatever) but having a proper view of what you are doing on the inside while navigating a repair is absolutely a step in the right direction!
Luckily I found this video. I thought my sensor was bad, so I received a replacement part. After swapping it out, it still didn't work. Then I followed the steps in this video, using the grease that Bambu supplies you with, and now it works. Very helpfull. Thanks.
I had the same issue with my X1 carbon actually and it appears that they are using the exact same metal lever in there. A quick shave of the plastic around it prevented it from getting stuck again.
I love a good troubleshooting episode! It's helpful to see how to break down a problem and it's a good reminder that this hobby isn't always "press button get thing".
I just spent 10 hours trying to replace my A1 mini extruder because I thought that was the problem, but after seeing this I'm sure this is it. Thanks. By the way I couldn't find anywhere with a video on replacing the extruder and with the screws being hidden and have to pull off the back plate to access the board I was scared to death I was doing it wrong. You do such a great job explaining I think it would be helpful if you could find the time to make one.
I think this is a great showcase in the art of troubleshooting. There will be cases when there isn't a blog post or youtube video to help you figure out what's wrong. If you learn how to think critically about how things work, you can troubleshoot without the need to go online. Good stuff.
For those worried about putting this back together, I would recommend trying to put some of that lube/grease on something like a toothpick and schmo it against the side. -The amount of grease put on there is probably not more than what you apply with your fingers when you swap out the filament spools.
You could use a small syringe (like those used by diabetics) to apply the lubricant to the spring without removing the spring (and possibly of loosing it). I’ve done this several times before and it works
Thx - after watching your video I could fix my A1 Mini (first major error after over 800h of printing) in under 5 Minutes. I did not take it apart like you but the sensor is coming out again after a little push with a fine tip from below.
Great fix and well made and instructive video. I just noticed how your wall of open rolls sighed, when you busted open a new one, for a measly 30cm filament :D
Great video showing the troubleshooting process Joel, thanks. I really want an A1, but they won't be available until may so I might grab an A1 mini to hold me over. I'm at my wit's end with my ender 3 pro. Reliability has been a huge issue.
Transparent cases as so cool. We need to get more products with it so we can all better understand how it works. BTW, fixing a Bambu Lab machine with a Prusa lube is... interesting! 😅
Something to think about is that the problem MAY have happened BECAUSE the case was transparent. This material might have played a role in the mechanics failing.
with that magnet, meaning its halleffect sensor ? would be cool if the a1 mini could compensate for filament diameter with it like calibrate it with 3 known pieces of different sized blanks ( like metal rods ) and then it could detect deviations in filament diameters, and compensate
Are you sure it wasn't the spring catching on the plastic? If the hook on the short end of the spring is slightly too long it would catch on the plastic and not push the metal bit in place. If it happens again, you might want to consider this. Good video.
I wonder if i can order a couple of these parts for when i have issues. Had the error "toolhead not reading filament" last night in the middle of a print. Tried some normal troubleshooting then decided to give up. After doing some research, one of the possible solutions was to turn the machine off and then on again. Turns out that was my "fix". But now im concerned that the sensor is on its way out. Just got the printer a week ago. lol.
You can always print a filament cleaner that you put a sponge into and put a few drops of 3 in 1 oil ,this should help in the same way and some filament manufacturers suggest to do this.
You are so awesome, loved this whole vid and the intent behind it. To me, this vid is a great example of how cool and connected society can be. To me, the 3d community is just a microcosm of society at large. We are a group of doers, creators, tinkerers. Life and living can be so much fun, Mass produced micro stuff is subject to malfunction, understanding how it all goes together and functions empowers us to fix (and improve) stuff... again, a basic tenet of RepRap community. Beyond the concern you note of possibly polluting filament, i wonder about the need for reapplying lube? I.e., lube is usually an ongoing or repeat process? A thought i have on how to make the surfaces more slippery long term, maybe ceramic coat them? idk, i have ceramic coating i used on my car and is makes it so slippery (well, hydrophobic) that water slips off. But the reason is reduced friction.
Would you happen to have an idea why the Bambulab A1 would start a print, then a few lines later goes to purge, then continue to print then purge again. ANY ideas or help would be much appreciated! Thank you
I literally just had this problem in a new A1. Drove me nuts and I lost a 93% complete Turbo fan from the Jet engine model. I could have saved it, but I moved the toolhead and once I tried to resume it just crashed into it and at that point after 1-2 hours of trying to fix it, I said fk it.
Thank you Joel! I had exact the same problem but i thought it was the little magnet that was missaligned... i did't know the exact position of the magnet so i encounter many failed prints from the multicolor panda, i also lost the tiny spring and was searching for hours in my room but can't find it so i make a support ticket for bambulab ,hoping they can help and also explain gow to put tje magnet because its moving sometimes in the proces and then there is no connection with filament sensor.. i spend 2 days working on it...i hope this can help people because there is no information (or spare part) what i can see on the internet 😢
What about dry lubricant? Can you use a bit of lock/key dry lubricant or a low tech option like a bit of graphite? That should reduce a problem with a *wet* lubricant. Since I don’t have one these myself, nor am I an engineer, I don’t know if that would interfere with the magnet or electronics.
Joel, Hi! Great trouble shooting video! Thx! BTW, what camera and lighting setup did you use for the super clear closeups of the spring assmbly? Excellent photography!
Bambu does seem to have some issues with cutting out or forgetting to lube parts entirely lately - there's been a spree of needling bearing failures in P1 and X1 extruders because they we're greased or didn't have near enough - a lot of the AMS first stage feed and retract issues around xmas turned out to be not enough lube on the nylon gears resulting on nylon shavings all in the feeders even with very few hours. Take note folks, a little bit of lube makes everything more fun.
Be interesting to know if the production models are any different. They may have used a plastic which has less friction for that part. Friend & colleague used your aff link to buy 1, with the 10% off, so will check it out next week.
Now time to make a video solving the problem about nozzle kicking the prints all the time. Your machine is a prototype, just like ours. The "user friendly plug and play machine with automathic calibrations" results to be, another 3d printer like all, or even worst.
I have a love hate relationship with my printers. My A1 mini was crazy reliable until today, where now I cannot get anything to stick to the bed. Ugh…. Feel a bit lost now since it’s not a conventional 3D printer. The lack of tram controls raises doubts if this is a bed level issue.
Hello. I am an A1 user and I think it gets clogged when printing. The printer becomes clogged in places where filament should be left dotted on the surface. What is the reason of this? Please help
i got problems with calibration is not working. it do the calibration then start the print. it is ok at the left side of the bed and the more to the right you get the worse it gets. all the way to the right it will not stick to the bed. bambulab say to fasten 4 screws on the back side of the black thing behind the nozzle. did that but did not help
Whether it needs to come out, or go in, gently pressing downwards with a fork on the flat side between legs and tube makes The Bowden Tube simple to work with. It also may spark interesting conversations on a dinner date for two if this is done prior to sitting down at the table. Feel free to share your story if this works for you.
**Disclaimer - I dont own an A1** Question tho, would applying a small bit of the grease to the axle have achieved the same thing or was it actually rubbing on the side of the housing? And if its rubbing on the housing, would sanding or somehow removing a small bit of material have helped?
Formerly Twitter…it’s X, call it X. New premiership. Beyond that, I own a X1C and think the mini was purely to destroy prusa, not really something anyone needed

Makes sense but this is excelent as test printers before launching globally

The amount of innuendo is crazy if a normal person was listening. Clear covers definitely help and need to make a comeback.
I have the Bambu A1. Working fine so far, knock on wood. This is a great piece of info, if I run into this problem. Thanks.
and now there is a recall on the hot bed if you have a damage cable lol

I like how he had to open a new spool of plstic to show how the sensor works versus turning around and grabbing from the wall XD

would be cool if the a1 mini could compensate for filament diameter with it

Clearly we need more translucent printer pieces. It's the only way I can see going forward. (Also it gives old N64 vibes that I love)
Like the first Game Boy ...transparent is the Best 😍
Thank you, Joel, for yet another example of #PositivePrinting!
Definitely an idea for someone to make a transparent 3D printer and sell it as a learning tool.
