@phaedrux said in CoreXY axis don't move at printing:
My apologies, I didn't intend to sound sarcastic. It was just that a quick google search turned up several options in multiple sizes.
Here's a 330x330 24v: https://www.aliexpress.com/item/3D-Printer-MK2A-MK3A-Aluminium-Heatbed-Thermistor-Build-Surface-Sheet-300mm/32948965327.html
I bought now this one https://www.roboter-bausatz.de/833/mk2a-heizbett-300x300-mm because the one from aliexpress would take nearly one month to be send to me. But with your link I got the right model and found a lot of matches. Big thanks.
@dc42 The new LCD arrived today and the pins on the new board were in the above orientation when I tested it with the meter, I plugged it in and it works perfectly
I think the old one was an MKS one from Ailexpress and as you suspected the pins were rotated.
It might be worth adding a warning on the wiki ensure others don't have the same issues (But in my case no long term damage was done)
Thanks again for the support in solving the issue
