    Guys, I need your help to wire my controller. I tried several times but I cant make the motors to move.

    Connections:
    Controller +5v to Pul+ jumped to Driver Dir+ jumped to driver Enbl+
    Controller step to Driver Pul- to
    Controller Dir to Driver Dir-
    Controller ENA to Driver Enbl-
    Posts in the planetcnc forum takes a while to get approved so I'll try here.

    If you haven't already, check out this video by @Kyo about how to wire an arduino to the driver. It might give enough information to make analagous connections from the planetcnc board.

    Also take a look at this forum thread:

    Smoothieboard with DQ542MA

    Try removing wires from the ENBL+ and ENBL- plugs. If those are unwired, then the board should be enabled. If there is current through them, then the boards are disabled.

    Removing the ENBL+ and ENBL- plugs made the z motor move, but only that motor. I also noticed that the motors are getting hot and that the brightness of the LED indicators are different.

    Here are the dip switch settings(set at 2.84 peak and 1600 pulse/rev)

    I got things moving. Used common cathode wiring and I got motion. I thought I had driver issues because of the LED indicators but maybe they just came from different batches.

    If your motors are overheating, then perhaps you have too much current. The person from the other thread had a different dip switch setting than you do for the current. It might be worthwhile to double check the spec sheet and look at what the other setup did. I think they also had the high torque motors.

    Got the heating issue sorted. My dip switch settings are correct. One of them just got moved that's why one of the motors would heat-up. Thanks for the help.

    Tested and working!

    That looks pretty awesome. If you could outline and/or photograph your final dip settings and wiring setup, that would be awesome. I've been thinking of using those drivers myself and the more documentation about 'working' setups, the better.

    Will do that after I install the steppers. I'm sure about the amp settings but not about the other half. This is my first cnc. I know nothing about microsteps and other settings. So happy nothing is broken. Its hard to purchase parts from where I'm from. I only know one person from my country who has an opensource cnc.

    What were your final switch settings? I too am doing this for the first time.
