Homing direction reversed after firmware update

Duetfan223

My config.g files and homing files seem unchanged. I have a CoreXY machine running off a 0.8.5 board.

I was running 1.21.2 and upgraded to 1.22.6. For now I will change the homing direction in home_.g files to compensate for this.

Has anyone else experienced this behavior before?

@Duetfan223 I think that gotcha is in the firmware release notes https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-1.x-&-2.x#version-121 but I can’t find it right now.

Upon closer examination, X and Y axis are correct but their directions are wrong. Z is unaffected.

I changed the stepper direction in config.g from:

M569 P0 S1 
M569 P1 S1

to:

M569 P0 S0
M569 P1 S0

Since P0 and P1 are the steppers attached to the X and Y axis (on my machine). Now it's working properly.

I see now, thank you. I'll keep that in mind next time I encounter strangeness.

It's in the release notes for version 1.19:

Important! On a CoreXY machine, if upgrading from a version prior to 1.19beta9, you need to reverse the Y motor direction in the M569 command. Similarly for CoreXYU machines.

@dc42 I see. I had upgraded from 1.21.2 to 1.22.6, FWIW.

Ah OK, in that case I don't know why you had to change the directions.
