So i've finally had chance to get the BCN3D Sigma setup and near enough working apart from one issue. I can't use the right extruder to print!
It will move fine using G1 U30 etc… and it will home as expected.
When i try to print with the right extruder it will extrude the filament as it's printing but it just won't move, it heats fine aswell.

Any ideas? I've had this working before on the BIG printer so i know it's something i'm doing wrong, i just can't put my finger on it.
My mistake was:
M563 P1 D1 H2 X6 ; Define tool 1
Should have been:
M563 P1 D1 H2 X3 ; Define tool 1
I presumed X was the drive number, not the axis number!

So, how is Duet working out on the Sigma?
That printer has a lot of vibration when in full flow: can imagine you might see some improvements in print quality?
It's cut the noise down no end
Prints are a lot lot better
This was printed at 80mms. It looks a little rough due to the glitter in the filament.

well done, looks like you have yourself a dream machine!
the standard BCN has a neat levelling setup: what are you doing for levelling now?
Well for the Z offsets i do it manually. It's fairly easy to do. To get the bed level i use the same method as BCN3D do by using both Z microswitches and working out the difference. It's manual in respect to working out which knob to twist but it's not a big issue.
