What is the problem?

When i press the X-Y Home button on Octoprints Control tab, the first Gcode sent is G91. Apparently Klipper doesn't like that and sends 112. End of story.

Send: M105
Recv: ok B:30.4 /0.0 T0:24.4 /0.0
Send: M105
Recv: ok B:30.4 /0.0 T0:24.4 /0.0
Send: M105
Recv: ok B:30.4 /0.0 T0:24.5 /0.0

press home x-y button

Send: G91
Recv: // Shutdown due to M112 command
Recv: // Once the underlying issue is corrected, use the
Recv: // "FIRMWARE_RESTART" command to reset the firmware, reload the
Recv: // config, and restart the host software.
Recv: // Printer is shutdown
Recv: !! Shutdown due to M112 command
Changing monitoring state from "Operational" to "Error"
Send: M112
Send: N2 M11235
Send: N3 M104 T0 S034
Send: N4 M140 S0*97
Changing monitoring state from "Error" to "Offline after error"
Connection closed, closing down monitor

What did you already try to solve it?

when i manually send G28 G91 X0....... it works normally.

Have you tried running in safe mode?

Yes, same problem.

Did running in safe mode solve the problem?

no

Hello @Uncle_guido !

Using the Home X/Y button should not send a M91. That would not make any sense.

G91 is Set to Relative Positioning and should not cause a M112 in Klipper.

UNLESS:

Your Klipper installation is that quirky

The issue is this (line #9):

This is a Klipper issue and you should consult the Klipper forum:

I just checked on my system and the Home X/Y button does indeed send a G91 before it sends the G28 X0 Y0 (and a G90 after). OctoPi 1.0.0cam, OctoPrint 1.9.3.

We can argue over the why but I think Klipper's response to the G91 is wrong.

Ok, you are right, but the response of Klipper results on this:
