Error: This kinematics does not support auto-calibration

[DekJak]

Hi All.

I’m rebuilding my printer and have upgraded to RRF3
I'm using a Duet 2 Ethernet controller and M122 reports
RepRapFirmware for Duet 2 WiFi/Ethernet version 3.4.6 (2023-07-21 14:08:28) running on Duet Ethernet 1.02 or later

I’ve started with new configuration and supporting .g files.
I’m trying to get my BL-Touch sensor to work and I’m running into a problem.
In Config.g I have...
; Z-Probe
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height

M557 is commented out

HomeAll.g just contains the movement commands to set the home position

Both Deployprobe.g and Retractprobe.g work as expected.
G30 S-1 works and reports the current position

HOWEVER,
G30 S0 works, sets the z height to 7.5 then reports...
“Error: This kinematics does not support auto-calibration”

Anyone have any idea what’s triggering the error?

Best

@DekJak try using just G30 without the S0.

@dc42
Many thanks for the very quick reply.
G30 without S0 works perfectly,

Cheers

@DekJak thanks. I've created https://github.com/Duet3D/RepRapFirmware/issues/910 to track this.

dc42 created this issue in Duet3D/RepRapFirmware

open Review behaviour of G30 S0 #910
