Manual Levelling Error: Number of calibration factors
-
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 G32The 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 -
Sorry, should have said that this is a CoreXY printer running firmware 2.02(RTOS) (2018-12-24b1)

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. -
No, if you have 4 independent leadscrews then the S parameter on the final G30 command should be S4.
