I just installed the dual head and now the z axis doesn't work. The bed only goes down, when it tries to go up it goes down instead.
It seems to be something to do with the second extruder motor. If I unplug the cable for the new second motor, it works fine again.
Z axis won't go up
Re: Z axis won't go up
I had that problem, too. I had the new extruder plugged into the wrong spot on the Rambo. Check to see if your new extruder is plugged into the port at the back of the Rambo. I had to move one of the wiring harnesses to get to the correct plug.
Re: Z axis won't go up
I think you're right. My bad. Thanks
But now that I have it up and running again, at least as a single extruder machine, I'm going to hold off fiddling until my son finishes printing some critical robot pieces for the FTC world championships next week.
