Homing X axis and Y axis isnt working

mlbuxbaum123

Duet2 ethernet with RRF 3.4.2
X axis will move towards the left (which it should) and stop way before it gets near its endstop, while the Y axis fights itself moving towards the rear (which it shouldnt). I have been fighting this machine and board for a few days now after finally powering it back up after 2+ years. Custom built Core XY Hypercube. I really need some assistance getting this machine producing prototypes. PLEASE HELP. I can send copies of any file you need

Thanks

@mlbuxbaum123 sounds like a wiring issue with the Y motor. Check all the crimps/pairs using a multimeter

Was it moving correctly before? Is there now binding after 2 years?

It may also be worth going through the corexy commissioning guide, particularly the motor tests.

@mlbuxbaum123 If you haven't turned it on for 2 years, you could have been running the older RRF v2 firmware. You have updated it recently, as you are now on RRF 3.4.2. Have you made the relevant changes to your config? See https://docs.duet3d.com/User_manual/RepRapFirmware/Migration_RRF2_to_RRF3

Please post your config.g and homing files.
