Help me with dual z motors
-
Hi,
I am using duet 2 wifi, 12v PSU and 2 Z motors.
when i do "G1 H2 Z10" only one motor is rotating & another is making some noise and not rotating. this when in no load condition itself.
thanks in advance!

do not use H2 for the testing
post your config.g
how are the motors connected.
what are the specs of the motors -
Thanks for your reply...

Both the motors are connected in Z pins, & motors are NEMA17, 4.2kg/cm with 1.2Amps
-
the motors on z are wired in series. this haves the voltage.
6v will not be enough to drive the motors.connect the second z motor to e1.
change M584 X0 Y1 Z2 E3 to M584 X0 Y1 Z2:4 E3
place the jumpers back on the second z connector.M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0tempyour thermistor settings are incorrect. find the correct beta value in your thermistor documentation.
you have not pid tuned the bed or heater.
G31 P500 X0 Y0 Z0 ; set Z probe trigger value, offset and trigger height
you are missing the offset of the probe

@Veti, thanks a lot for immediate reply...
Z motors are sorted now....
will check the thermistor settings...

@Veti said in Help me with dual z motors:

yes, yet to do... thanks!
