If I home from Mainsail then everything homes, X then Y then center for Beacon. If I home again from Mainsail same thing. But if I go to print, after wipe and then home, the X axis is off by say -75mm? Is there something in my klipper settings/macros that might cause this to happen during print start macro?

Sounds mechanical to me
Loss of steps, that kind of thing

That’s what I’ve been trying to fix. I was seeing layer shifting during long 60C chamber prints so I’ve been modifying my tmc autotune and current settings trying to clean up homing. This finally seemed to home fine from mainsail homing, no loud forcing against the sides nor sliding on the other axis. This is sg4_this setting and the current settings in the macro.
This has been a lot of hassle though. I might need to just go install limit switches.

You should try turning off tmc autotune, see if that changes things

hey
@fallen kestrel
are you using tmc autotune?
[autotune_tmc stepper_z]
motor = ldo-42sth48-2004ac
[autotune_tmc stepper_z1]
motor = ldo-42sth48-2004ac
[autotune_tmc stepper_z2]
motor = ldo-42sth48-2004ac
[autotune_tmc stepper_z3]
motor = ldo-42sth48-2004ac
ok, yes...
remove this and use interpolation: false
there's aparently a bug with TMC autotune
