Just got it this week. Then got unit assembled today. Only to find one stepper functions swapping cables on board problem stays with the board as non functional works and functional becomes no functional. Is this board problem or program issue
Hello @Whop, welcome to the forum! Thank you for the info, and trying out different troubleshooting steps already. Is this 4.0 or 4.1?
Are you able to share picture(s) of your setup showing which Stepper connector or TMC2209 driver chip you think could be an issue?
Some close up well lit focused pictures of your connector and TMC2209 chip could be insightful. May need heatsink removed for those types of pics though
The heatsink would then need to be stuck back on using thermal paste… So, I totally understand if this isn’t troubleshooting tinkering you have time, or interest in getting deeper into 
.
Am asking all these questions based on some recent related topics. Some people benefited by reflowing, and/or creating a splitter cable that drives both steppers from the one working TMC2209 driver. Hopefully regulars here will chime in to help get you up and running soon. Cheers!
I got new board coming now. It is 4.1. I may not be best person messing around with boards. I’m lucky to get cords connected to it without damaging something. I was going to also order extra set of belt but they were sold out
