I'm having a problem printing and was hoping someone has ideas. In May I build a large scale printer (Tronxy x5as). This is a core xy printer. I am gettig shifting when I print. The
X and Y axis belts are tight and have tensioners. I've tried slicing with Cura 4.10 and 4.9.1. I have used these stls before and they printed fine. Print bed adhesion is also not a problem.

Thanks for all the suggestions. I've made dozens of prints with this printer including some very large ones. Nothing has changed,same settings, same filament, same everything. Tech support suggested I adjust the pots on the control board thinking the voltage is off. I think the board has failed and I will keep you posted on what happens.

I have 3 of them, 2 of whick are made by Fluke. I was a certified printer tech for 18 years.

Update, I checked the pots and they were good. I swapped the X and Y steppers and it still shifted on the Y axis. Tech support thinks the Y driver chip has failed and will send a new board from China. I think it failed because I do large prints (up to four days) and there are no heatsinks on these chips. The new board will get them and an extra fan. It might be worth checking if your printer has them. I think it would be a cheap investment to help keep the chips cooler.
