Awesome, thank you!

You’re welcome 😊

Thanks for saying so. I'm glad it helped.

@@MyEngineeringProjects Thanks for the video, it's very helpful as a novice doing this stuff. Can I ask why you only have 3 bed clips on the print bed in this video instead of 4? Is this a glass bed? And is there an optimal position to place the clips with regard to the CR touch? Thanks :)

Yes it's a glass plate. The 4th clip caught on something and fell off. I need to replace it. 2 in the front and 2 in the back about how I have them works best for me.

I don't have a Windows machine to test. You could open a ticket up with ZWO. It's possible you have a defective focuser.

Really similar. Be sure you have the EAF plugged into your PC [use power supply if 12 volt] then download and unZip the EAF_FWUpdate_win_v3.3.8.. Then Run ElectricDeviceFWUpdate_3.3.8.exe. If it doesn't open then you have to install the Microsoft Visual C++ 2008 Redistributable Setup [run vcredist_x86]. Then open the Update screen and scan for the EAF, then Run. The update will proceed. Very similar to the above Mac version. It will verify the update, EAF Version 3.3.8 or similar.

Good question. The ZWO focuser is already geared down, so placing it on the fine focus knob is not necessary. They specifically designed it to go on the course knob. It would probably work o the fine, but I have not tested it.

It worked. I do need to gear it down because this free refractor has no fine speed control. You can see the first test here ruclips.net/video/jrAV25ZPZSQ/видео.html

First check to see if your limit switches are connected. you might also need to check to see if they are plugged in correctly at the board. One loose switch connection can cause this issue

I designed and 3D printed a support bracket

@@MyEngineeringProjects I thought it might be that. Unfortunately, we don't all have 3D printers.

Not very long it’s just a demonstration battery. It has fairly low current.

@@MyEngineeringProjects will it work for a few minutes or hours? I want it to work during my school's science exhibition. Btw very nice video.👍

For a school science project, you can run the LED for a while a few hours probably it’ll be enough to show how it works

@@MyEngineeringProjects I have one more question for you. Can I use a thick aluminium wire instead of the galvanized nails?

It will work but bear in mind that each metal has different characteristics and produce different voltages.

I'll have to checkout that design. Glad you got it working well.

Ok.

Not sure what version you are using, but for V2 Try navigating to Prepare which is the top right, then going down to the A symbol which is just below the temperature symbol, then you should be able to find English. For other versions this would be different.

Try to increase the step size. During the calibration process, the ASIAir will command the scope to move a bit over and over. If it does not move enough to detect a change of position, the calibration process may fail. From memory I think mine is set to 2000 but I would have to confirm.

@@MyEngineeringProjects - Thank you - I'll give it a try!

@@MyEngineeringProjects - Just checked my step setting and it also says 2000. I did recently insert a different camera, so I'll try resetting as you mentioned in your video.

Yes very good idea. I had the same issue where I forgot to re-calibrate when I swapped cameras. Guiding failed until I deleted the calibration and started over.

This is likely a firmware issue. You might have the wrong version installed for your board. Double check your board and the version you downloaded from Creality's site.

Glad I could help!

I’m not sure since I have not used the sprite extruder but you probably will have to move the cr touch to the sprite.

I would try a different version of the firmware. Their website that has the downloads is really hard to navigate. Also, check the board version number and make sure it matches the firmware you downloaded.

@@MyEngineeringProjects How would I do that? I don't see any old firmware on the creality website. My firmware for the board number is correct.

I agree, but I don't like looking at it so that's why I put a lid on the box.

It would be challenging to do this. If you simply tried to scale the STL, then it would make everything bigger such as the nut holders and holes for the rods. This would break the design. One option is to import the model into CAD and then keep connectors the same but increase the size of the mirror holder and related parts.

@@MyEngineeringProjects I was also thinking it would make parts too large for most 3d printers. Would maybe have to divide them into the smaller pieces.

Glad it helped. Yes it is and it's also available on their mobile app. It's great for planning.

It the ASIAir won't recognize it, then likey it is corrupted or an incorrect format. I have had some usb drives fail without warning and cannot be mounted. Not sure if this your issue, but it's a good place to start. Try testing the stick in a computer first.

@@MyEngineeringProjects Thanks for your reply!

Interesting. I like the idea of the normally closed switches. I was lucky for sure. I heard a banging noise and knew I only had a few seconds to shut off the power. Fortunately the board and motor is ok but what a close call.

I don't have the pro version, but look for a spacer that should not be there like a washer of some sort. It also might be in upside down. Not really sure without looking at it myself.

I would check to make sure you have the right nozzle size and that it is not obstructed. If it's too small or partially blocked, that could cause under extrusion.

Thank you.

Happy to help!

Cool, thanks. I was tearing my hair out on this one. Glad I finally figured out what was wrong. I'm printing the next component now for the auto focuser.

Thanks, glad you liked it. Pretty cool that a cloning tool is built right into the software.

I'm not sure what went wrong. Keep me posted.

@@MyEngineeringProjects I found a video of some guy saying that some 4.2.2 boards have different memory sizes which causes screen glitches on some firmwares. This version worked for me and after fixing nozzle heating problem with PID tuning it works great. It feels so weird hearing Z motor all the time but I'll get used it. Thanks for your video, it really helped me with the installation.

Awesome glad you got it working. I was not aware of a memory issue but that's good information.

Not while I had the motorcycle. I have since sold it but it worked while I had it.

I'm wondering if the tension on the PLA is too low given that a larger diameter PLA worked.

You're welcome I'm glad it helped. Note that if you had the exact same issue as in the video, that means that the extruder bracket is broken. I didn't realize it at the time of shooting. It's a simple fix to replace it with a metal version.

@@MyEngineeringProjects I have the metal version. the grub screws must not have been tightened enough and the gear slid down out of alignment. Your video helped me take a closer look and see the problem. Thanks again

Ok great. Glad you got it fixed.

There are many options for video titles. This title was chosen due to the fact that someone who is having difficulty connection probably does not know it's related to the battery. By naming it as I did, it allows those with the same issue to find a solution. In addition, Wifi interference is also shown in the video which has nothing to do with the battery.

Great to hear. I'm so glad helped.

You will only see a black blurry blob

@@MyEngineeringProjects this is so sad

We have to remove 2 to attach the bracket, but we essentially put them back into the same holes when the bracket is installed. That will ensure that the focuser is securely mounted as well as the motor for the electronic focuser. I think this is why they are saying not to touch them.

@@MyEngineeringProjects thank you, that makes perfect sense.

Thanks

I have not tried that but it might work. What reason would you have to use 2 acids together?

@@MyEngineeringProjects once I was washing my ss pan with white coats of minerals due to boiling water, with Citric acid granules. I found that those streaks vanished. I 've seen it cleaning old coins as well so I thought why not to experiment.

Glad it helped. I didn't want to take my batteries to zero either. They did it for those who just want it done for them.

Yes you are right. Comets spew out gases and material as they heat up when they get close to the sun. This material forms the head of the comet. The material gets thrown out over millions of miles forming the tail. Really interesting.
