DuetWifi delta homing doesn't complete
-
Hi,
I've built a large kossel based on dc42's design. After wiring everything and running G28 to home I've noticed that it never completes.

G91 ; relative positioning
G1 S1 X725 Y725 Z725 F1800 ; move all towers to the high end stopping at the endstops (first pass)
G1 X-5 Y-5 Z-5 F1800 S2 ; go down a few mm
G1 S1 X10 Y10 Z10 F1000 ; move all towers up once more (second pass)
G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
G1 X0 Y0 F6000 ; move X+Y to the centreI've also noticed that M114 reports position as Nan: [c]X: nan Y: nan Z: nan E0: 0.0 E1: 0.0 E2: 0.0 E3: 0.0 E4: 0.0 E5: 0.0 E6: 0.0 E7: 0.0 E8: 0.0 Count 0 0 0 User nan nan 100.0[/c] Endstop switches are NC type and they report state change properly both in DWC and when queried via M119 What else can I check to figure this one out? -
The combination of R and L parameters in your M665 command is not feasible. If it's based on my design then the L parameter is much too small.

Thank you. That was it.
