G28 Home all behavior
I have sensorless homing setup for X and Y which seem to work independently if I home X and home Y. However, if I try to G28 home all, then it homes X correctly and the does not seem to home Y, it goes to the middle and then the back of the machine. I had to change a setting in the config to get it to home to the front, maybe I missed another step? I had to adjust "position_endstop: 0 # 200mm printer" for Stepper Y...it was originally at 200 for my size build and changing it to 0 seems to have it home Y to the front. Did I miss something else? TIA

Update, Y seemed to be triggering immediately after X homing. Played around a bit but didn't want to spend too much time. Swapped over to physical endstop and all good now.
Sensorless homing needs to be adjusted to the correct sensitivity

Well I know that lol I played with the motor current and stall guard, couldn’t find an acceptable sweet spot so I just went to physical endstops
That's cause it is really difficult because both motors are used to move in x and y. You only use one motor for diagonal movements

Yeah I just decided not to waste anymore time on it and got it going with switches. Not my first printer build by far lol
It is a simple matter of writing a macro that homes x then y then z. Works for me.
