      I am trying to convert an old replicator 2 with a duet 2 wifi board, when configuring the firmware all the motors work fine except the z axis motor, it has an erratic behavior, it turns to both sides and sounds a lot, I already checked the polarity and also update the firmware to 3.04 but there is no way to fix it. Then I modified the velocities and accelerations and got the motor to move a little more uniformly, since I had read that this problem was due to the low speed in the z axis but now it throws me this problem "Warning: Driver 2 warning: phase A may be disconnected, phase B may be disconnected."
      Your answer is probably to reverse the polarity and check the wiring, but the motor doesn't run when you reverse the polarity.
      Which may be?

              M566 X12000.00 Y12000.00 Z12000.00 E1200.00        ; set maximum instantaneous speed changes (mm/min)
              M203 X12000.00 Y12000.00 Z12000.00 E1200.00        ; set maximum speeds (mm/min)
              M201 X3000.00 Y3000.00 Z3000.00 E10000.00          ; set accelerations (mm/s^2)
              

              These values are far too aggressive. Try these instead.

              M566 X1000 Y1000 Z120 E1200        ; set maximum instantaneous speed changes (mm/min)
              M203 X12000 Y12000 Z600 E3000        ; set maximum speeds (mm/min)
              M201 X1000 Y1000 Z60 E3000          ; set accelerations (mm/s^2)
