I got a really big delta printer up and running with a duet 6HC and toolbar 1LC.
everything works fine apart from the mesh bed.
can't get a solid first layer, the Y direction is most of the problem. (See attached pictures)
can someone help me?
I'll share the following;
-Config.G
-Bed.G
-Simplify start Gcode and End Gcode

; Before running this, you should have set up your Z-probe trigger height to suit your build, in the G31 command in config.g.

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)
