    Hello,

    After following the instructions to wire the stepper motors in series the machine only jerks in place. What baffles me is if I connect the Y motors to the Z axis outlets (one in each) the machine goes on its course normally. I’ve tried reversing the wiring to one of the motors and the result is the same.

    Is that a real rambo, or clone?  The motor is acting like it’s wired incorrectly, so if it’s a clone, that’s the issue.  We’ve had a bunch of clones do this.  If it’s a real rambo, either bought from here or directly from ultimachine, then you’ve got a pin that’s either intermittent, or is loose in the connector.

    dear Barry,

    You helped me, indirectly, resolve the issue. I’ve started by checking the pins on the board, they are solid. Then I changed the dupont connector, and one of them was faulty. I’ll now resume the search for the next problem =)

    I had a clone board an had the same issues. First a loose connection and than a wrong board. Start using an original board. Keeps you out of problems!

    If you did not buy it from someone on this list you bought a fake.
