Z not working #35

Closed nobaj closed 3 years ago

nobaj commented 3 years ago

I don't know why my z motor is not moving, if I connect the motor to another axis, it works. . I also replaced the driver (they are both new drivers) but this does nothing.

Also I move the steps down to 80 to see if it was something to do with the steps per mm. Still nothing.

I tried both connectors, (I know they are in parallel with the same driver)

I used the same cable to connect the motor to another axis and it worked, (same cable, same motor different axis)

Is there a conf or something I need to change on marlin ?

UPDATE:

If I connect 2 motors (one in each port) it works..... But my printer only have 1 z motor, is there are marlin option to use only one? a jumper on board??? something???

UPDATE 2:

There is a picture with some jumpers in one of the z sockets.... It worked... I am so dumb.
