Hi
I am just getting my Carve King running and connected up tonight.
It looks like my stepper motors are running at different speeds.
One Y and the Z look like they are running fast and the other Y and X look like they are running much slower and closer to the distance when I move them a millimeter at a time. This means that the Y binds after a few 1mm jogs.
I made sure that all my screws turn easily by hand and that my gantry was sitting square.
Any thoughts as to where to check?
Thanks for your time
Warren

Are the jumpers set right on all of them... with jumpers on M0 and M1 underneath the drivers?
Are the adjustment pot screws set to 0.65 volts on each stepper driver.
Let us know and we will move from there.

Also, just to cover all the basis... can you please type $$ into the command line and press enter then give us a screen shot of the results. It should all be just fine there but I want to make sure it's all fine.

I checked the jumpers and they are all correct M0 & M1. Voltages are, X -.653 Z - .652 Y - .655 A - .652 I checked these with out the motors or homing switches plugged in and also tried switching the Y and A plugs ![]()  |

Switching the Y and A switched the speeds of the two motors

I tried stepping the different axis 1mm and counting the turns of the screw
Z one full turn
X one quarter turn
Y one quarter turn
A one full turn

This is admittedly pretty confusing to me. My only guess is that the jumpers aren't actually making contact at the jump points. Just to be clear, you have the jumpers vertically instead of horizontally, correct?
A 1mm move command should be a 1/8th turn, for what it is worth.
If that doesn't get it right we'll set some electronics up and send them out to ya. We'll be closed tomorrow due to the hurricane and I'm hoping to be able to get into the shop Tuesday.

Yes the jumpers are vertical and I compared them to the photos.
I will pull it apart and make sure that all the jumpers are seated properly tonight and then let you know.
Thanks and good luck with the storm

I took all the chips, jumpers, motors and homing switches off the main board and reseated them all. I checked the voltages and they were all between .649 and .653 I still have the motors turning at different speeds. I have two screenshots below with the initial start up and then the second is jogging the different axis's   |

Hi Derek
Sorry not to get back to you sooner, that new setup did the trick and I have it working well.
I noticed a big difference between the two boards, the one I sent back made the stepper motors really noisy when they moved.
I did put it in the mail on Saturday and have a tracking number for you:
USPS 9500 1133 5941 7259 0634 54
Thanks for all of your help
