Ok so I have all my motors hookedup. I have triple checked wiring…

When I try any motor hooked to the y axis port on the sanguinalolu they all work fine and the driver gets hardly warm.

Now when I try a motor on my x, z or extruder port they whine and the driver gets very hot relativly quickly.

Again I have douple checked all cables for shorts.

Any idea what could be wrong?

Do you have the correct board selected in Marlin? Have you tried the other drivers on the Y axis port?

3

I do have the correct board set. I’m going to try swapping tge drivers around and adjusting the amp pot

4

Mike you have the stepper motor pairs correct? You can check by shorting 2 of the wires of the motor till the spindle is hard to turn then you know you have the right pair.

5

Also did you try the ramps test.PDE arduino sketch to see if the motors work correctly? I can send it to you. I just did it on the electronics for my new rig, the motors work perfectly. It should work on your board.

Yup I have pinouts from the manufacturer and hooked them up the same way to each port. Basically all I’m doing is plugging in a cable running it on the y to make sure it works fine then switching the cable at the sanguinalolu

OK, this is why I decided to use a straight ramps 1.4 board so I don’t need to do this kind of troubleshooting.

8

It should be no different as the ramps boards use the same driver modules as I’m using

9

I figured that.

I’m also going to make sure and clean up any flux from where I soldered the headers to the driver boards

11

Use the flux pens they work the best

Ok I have finished swapping out each drive into the y-axis spot and they are all working as they should.

I also switched all my motors to the y-axis spot and they are all working correctly on that spot.

The next closest to working right seems to be the z-axis. I have it set to do 1/16th microstepping and im guessing marlin is not setup to do 1/16th by default.

Marlin doesn’t need to be “setup” for microstepping. You simply need to input the correct e-steps-per-mm. Z is going to typically be a larger value because of threaded rods.
