I have found this thread very useful, as I use the same proximity sensor (LJ12A3-4-Z/BX). My printer is now running properly and I am one step closer to homing the Z-Axis. So, thanks!

I still have my stretched benchy

UPDATE: The fan that I installed was bad. Problem solved! Watch out for what you buy on Amazon!

@jens55 My other 24v fan that I tried was working fine. I’m pretty sure that the blower fans I bought might be faulty. I’ll try plugging it in place of the working fan as soon as I get the time. Thanks for the advice!

@mrehorstdmd I have not been able to hook the fan up to a power supply. I am starting to suspect that my fans are faulty. I got them in a pack of 4 from Amazon, so I will definitely try to hook it up to a power supply to see if they work. (When I get the time of course)

Hello,

I recently converted my printer from a 12 volt power supply to a 24 volt power supply. Everything seems to be working EXCEPT my part cooling fan. I replaced the old 12 volt one with a 24 volt fan. When I use the slider in web control, the fan does nothing. I have checked my wiring, and there's no problem there. Really not sure why it isn't working. I'm running a Duet 2 Wifi on firmware version 2.03. My config file is attached for reference. Feel free to add any other suggestions. Thanks!

I still have my stretched benchy

To summarize, I set my Z steps per mm to 400.

I know that this is a bit redundant, but I reset my steps per millimeter to 400, and this time, I've finally got it. I would like to thank you all in this thread for making my printer the best it can be. And so, thank you all again for the amount of help you've given me.

Very interesting. Despite the fact of me figuring out my problem for the most part, My prints are appearing to be very stretched in the Z direction. I might want to consider changing it to a TR8x8. Thanks for the help.

Upon testing, I now have the right heights in mm. Thanks for the help!

Here's the bare bones kit I'm using in case it helps.
