Yes, it is a kinematic mount with ball screws. According to my logic, I wanted to use the "B" position too. Many thanks for your help

Okay, I found out for myself why: In the M584, I incorrectly addressed the extruder stepper!

WOOHOOO - it works

At the rear is a magnetic spherical recess, front right is magnetic v-groves (45° to X and Y axis) and front left a a plane round magnet

@fcwilt
In my opinion, this is the only way the bed can expand in all directions without rotating around the spherical recess

Hey guys,

Set up three Z-axis location - M671- in RRF3 on Duet 3 MB6HC:

Which coordinates should I enter? The real ones of the leadscrews (A) or the ones where the bed actually rests (B)?

Will that be built in at some point?

Hello Friends,
I exchanged my Duet 2 Wifi for a brand new Duet 3 + Toolboard1LC. Now I'm configuring and most of it already works (homing x / y / z, heat up hotend - Bed heater is not connected so far)
But when I wanted to adjust my extruder, the error message comes up:

Warning: motor phase A may be disconnected reported by driver(s) 5
Warning: motor phase B may be disconnected reported by driver(s) 5

The Stepper Motor on driver 5 (Toolboard) is a Nema17. I can measure the motor coils with a multimeter directly on the toolboard, so the motor has no cable break.

I took the config.g from a template for my printer and only adjusted the in/outputs.
Please tell me that I only have a bug in config.g and not that the toolboard is broken.
Thanks for your help

@dc42
I have grounded my printer frame with the ground of 220V power outlet. Should I disconnect this grounding and instead connect the frame to the negative of the power supply output? Or must this connection persist and additionally the negative output connect to the frame?
