@alankilian Yes but not completely. I have the U axis set up....mostly. It doesnt give a whole lot of detail on homing setting up the homing files. How do I attach my config.g so you can take a look?

@SonnyD1 said in I am at a loss:
Y sounds like the two Y axis motors are fighting in opposite directions,
If you remove the belts on the axis can you see if they are actually rotating in the correct directions?
It's best to test each motor individually at first to confirm correct operation and rotation before ganging them together.
-
@Phaedrux so that was one thing I just figured out. I unplugged one motor and homed Y. I repeated this for each motor and discovered how the obvious escapes me sometimes. The motors are mirrored so obviously one would be backwards. Fixed that now moving on. Still trying to get a complete homing cycle. Thank you very much for the reply.

@SonnyD1 Set up each axis homing macro first, ie homex.g, homey.g, homez.g etc, and concentrate on individual axes first. You can set homeall.g to just call these in order. The main advantage of using homeall.g is that you can home X and Y at the same time, to save a few seconds of homing time. If you are still struggling, post the homing file you are having problems with.
For examples of homing scripts, see (cartesian) https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_cartesian#homing-files and (IDEX) https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_IDEX#homing-files

@SonnyD1 maybe my config helps for reference: https://github.com/oliof/printerconfigs/tree/main/cr20
-
@oliof I appreciate it. I'll definitely take a look.
-
@droftarts Yea I'm gonna work it one axis at a time. I'm gonna continue to work it and let you guys know how it goes. Its gets frustrating sometimes.
-
@droftarts I cant seem to find an example of a homey.g. Do you know where I can find one?
-
@SonnyD1 it is effectively the same as the homex.g example from the link I gave earlier. Change the G1 X… commands to G1 Y… moves. If you have the motors moving the correct way now, you could use the configuration tool to generate these files now.

@SonnyD1 You appear to have one endstop for the Y axis. If you have two motors for Y, driven from separate drivers, you need some way of homing both motors (you can have one endstop per motor in RRF) in case the motors get out of sync, which will skew the X gantry. Usually, this is done with an endstop on the second motor as well. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling#axis-levelling-using-endstops
