Ratos, Prusa Einsy MK3, homing moves right instead of left.
I'm not finding where I can change the homing settings. I want the printer to bump on the left side of X.
Motors and everything else is working fine. It's just the homing behavior I want to change.

take a close look into your printer.cfg - everything should be there. if you can't find it, post and somebody may look into it. That's if the problem is not in the wiring 🙂
thanks. Looking. I'm not very familiar with Klipper. In Marlin, there was specific homing configuration. I'm not seeing a section like that in any of the RatOS files.
doubt it's wiring. Stock MK3s with Ratrig's MK3S profile.
I think this is the section I need to change if not Macros

[gcode_macro RatOS]
variable_homing: "sensorless"
variable_sensorless_x_current: 0.4
variable_sensorless_y_current: 0.4
this is out of RatOS's sensorless-homing-tmc2130.cfg defaults
here's the homing.cfg file. I'm assuming it's intentionally set to bump the right side. Either would work. I just happen to have a cable mess on that side at the moment.

have you tried to alter the postion_endstop value of the x stepper? it may not help, but it may ^^
