I need some help. I have just instaled the new extruder, "The orbiter", for minimizing the weight. Unfortunately I am having problems with the motor.
I have bought 4 motors from Wantai (36BYGH218, 1.8A, 1.8deg/step)and tested them all, so I do not think it is the motor's problem, because they are all doing the same noise; like ggrrrrr, loosing steps. Nor the board has problem because for ease of practicing I have tried driver3 and driver0.
I have checked the wiring twice. The connections are B, A, A, B on the duet, the same for my motor. I have also tried swapping the cables but is not working either.
I have put the configuraton for the extruder as per instructions:
Stepps: 655 stepps / mm @ 16 micro-stepping (for the 7.5:1 gearing ratio)
Acceleration: 600 mm/s^2
Maximum instantaneous speed change (jerk): 300 mm/min(RRF), 5 (Marlin)
Maximum speed: 3600 mm/min
Pressure advance: 0.03s
Retraction: 1.2mm (for the volcano V6 hotend)
Retraction speed: 60mm/s
0.9A Peak or 0.63 RMS(Wantai 36BYGH218)
I have tried different currents 1400mA, 1000mA, 900mA and 700mA but still doing the same.
Part of my config:
M569 P0 S1 ; physical drive 0 goes forwards (X axis)
M569 P1 S1 ; physical drive 1 goes forwards (Y axis)
M569 P2 S0 ; physical drive 2 goes backwards (Z axis)
M569 P3 S1 ; physical drive 3 goes forwards (E0)
M569 P4 S0 ; physical drive 4 goes backwards (Coupler)
M584 X0 Y1 Z2 E3 C4 ; set drive mapping
M350 C8 I0 ; configure microstepping without interpolation
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X100.00 Y100.00 Z400.00 E655.00 C100.00 ; set steps per mm
M566 X400.00 Y400.00 Z10.00 E300.00 C2.00 ; set maximum instantaneous speed changes (mm/min)
M203 X16500.00 Y16500.00 Z1000.00 E3600.00 C5000 ; set maximum speeds (mm/min)
M201 X4000.00 Y4000.00 Z400.00 E600.00 C400.00 ; set accelerations (mm/s^2)
M906 X1200 Y1200 Z1000 E900 C400 I30 ; set motor currents (mA) and motor idle factor in per cent
M84 S120 ; Set idle timeout
