RatOS homing behavior

Hi guys, I recently swapped to RatOS, just wanted to ask what the homing behavior is supposed to look like, since when I homed last night, the probe was left hanging out of bed in the front left corner and the bed crashed like hell 😅

Solution:

thanks for the suggestions! Turns out sensorless homing was off a little, so sometimes it homed correctly other times not as much, so it was acting wonky.

you need to adjust your offsets so that 0,0 is on the front left of the bed corner. So home X, and then home Y (DON'T HOME Z). tell it to go to 0,0. Then adjust until it is on the left corner. Whatever the difference is, is what you need to adjust for your x and y offset

[stepper_y]
position_endstop: <your size - the offset>

[stepper_x]
position_max: <your size - the offset>

[stepper_y]
position_endstop: <your size - the offset>

position_max: <your size - the offset>

I havent done the X/Y offsets yet, as I wanted to home the actual printer first and got a little sideswept by the homing failure
