MBLA, not getting it right.

RogerL

Hi,

I been reading instructions on how to configure manual bed leveling assistant but I cannot get it to work correctly.

I have a carthesian printer and four corner screws to adjust my table.
Can get it to probe using G32 and it does all my four corners but resports back a error:
G32
Error: Number of calibration factors (3) not equal to number of leadscrews (4)
I been trying to figure out how to set this but no luck.

Here are my Bed.g lines
G28 ; home
G30 P0 X0 Y0 Z-99999 ; probe near an adjusting screw
G30 P1 X350 Y0 Z-99999 ; probe near an adjusting screw
G30 P2 X350 Y223 Z-99999 ; probe near an adjusting screw
G30 P4 X0 Y223 Z-99999 S3 ; probe near an adjusting screw and report adjustments needed

Here is my config.g lines
M671 X-15:350:350:-15 Y-12:-12:250:250 P1.0 ;

Any ideas what I do wrong?

See that S3 at the end of the last G30?

That number has to match the number of G30 commands.

So change S3 to S4.

@rogerl as @fcwilt says, also change P4 to P3.

That worked but I got a new error
G32
Error: Bed calibration : 4 factor calibration requested but only 3 points provided

All good now with both changes, thank you
