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

Cheers

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?

@DekJak said in SD Card corruption again, again:

Hi, I just had this problem too.
I used the printer a couple of weeks ago without problem.
Today, when I turned the machine on there are no files on the SD card.
I don't log to the SD
The SD card is the one that was supplied with the duet.

What's the best way to recover from this?

Hi Again,
Just read the SD card in a computer reader and all files are on the card.
Popped it back into the Duet and all OK again now.
Must have been the re-seating that fixed it.

OK, I got it.

The final S parameter should be S-1.
I was just following the example in the "Using the manual bed levelling assistant " which shows S3 and not the Gcode manual which shows S-1.

Sorry, should have said that this is a CoreXY printer running firmware 2.02(RTOS) (2018-12-24b1)

Hi All,
I’m trying to do a manual bed level for the first time and I’m running into the error:-
Error: Number of calibration factors (3) not equal to number of leadscrews (4)
I'm starting the levelling command with G32

The M671 command in my Config.g is:-
M671 X41:327:327:27 Y-35:-35:425:425 P0.5
For adjusting screws starting near the origin and working anti-clockwise round the bed at :-
X Y
41 -35
327 -35
327 425
27 425
The four points are probed without any visible error.
Can anyone see what I'm doing wrong please?

My Bed.g is:-
G28 ; home
G29 S2 ; Clear height map
M561 ; Clear Mesh Levelling
G1 X10 Y10 F5000 ; Make sure the probe is clear
M401 ; deploy Z probe
G30 P0 X0 Y0 Z-99999 ; Dummy probe point
G30 P0 X41 Y0 Z-99999 ; probe near P0
G30 P1 X310 Y0 Z-99999 ; probe near P1
G30 P2 X310 Y390 Z-99999 ; probe near p2
G30 P3 X27 Y390 Z-99999 S3 ; probe near p3 and report adjustments needed
M402 ; retract probe
G1 X0 Y0 F5000 ; back to origin
