Manual bed level setup - I have to be missing something

Iamturbo1978

Hello everyone,

I really think I am missing something.

I'm trying to setup a 4 point manual bed leveling, but I keep getting an error. I've checked, and checked, and checked, and checked, both the config and the bed files. I can't for the life of me figure out what is going on.

Could someone please take a look, and tell me what I am missing?

Thanks

The error I am getting;

G32
Error: Number of calibration factors (3) not equal to number of leadscrews (4)

My config;

M671 X67:217:67:217 Y0:0:287:287 P0.8

Bed file;

G28 ; home
G30 P0 X67 Y0 Z-99999 ; probe near an adjusting screw
G30 P1 X217 Y0 Z-99999 ; probe near an adjusting screw
G30 P2 X67 Y287 Z-99999 ; probe near an adjusting screw
G30 P3 X217 Y287 Z-99999 S3 ; probe near an adjusting screw and report adjustments needed

From: https://duet3d.dozuki.com/Wiki/Gcode#Section_G30_Single_Z_Probe

On the last G30 command in the sequence, the S parameter indicates that a complete set of points has been probed and instructs the firmware what sort of calibration to perform. If the value is -1 then the Z offsets of all the points probed are printed, but no calibration is done. If the value is zero or not present, then this specifies that the number of factors to be calibrated is the same as the number of points probed. Otherwise, the value indicates the number of factors to be calibrated, which must be no greater than the number of points probed.

I'm guessing that you will need to change the "S" parameter in your last G30 to be 4 (or 0) so that the number of factors is equal to the number of leadscrews.

@garyd9 See... I knew I was missing something.

Thank you so much, that is what I was missing, and it totally worked.
