Solved Bed Levelling with independent Z motors error
-
Hi All,
I'm trying to setup z gantry leveling in a cartesian printer with independent z motors.
I've read through https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors and I can't seem to get it to work. Can you see any errors in my config.g, bed.g homeall.g which may cause this?
I'm still working on getting my 3hc board working, but all the z drivers are connected to the main duet3 6hc board.
I get the following error
"Error: Number of calibration factors (2) not equal to number of leadscrews (4)."config.g

@fcwilt
Thanks fcwilt. the error still persists with the capital S. -

@fcwilt
Thanks fcwilt. the error still persists with the capital S.Well it was a long shot at best since nothing else jumped out.
Must be missing something. I'll take another look.

Ah... there it is.
You have a second M671 at line 105 of the config file list which is specifying 4 lead screws.
