DMC2 Mini Mill - build and review

I can't really comment on Mach3 - never used it. But fundamental troubleshooting techniques apply.
Start with just one axis plugged in and powered on. Try to get it going. Any movement at all or moves and then faults? How did you configure the drives, and Mach3?
If I recall correctly - I think my stepper motor wires were not the same color coding as the manual and I had to figure that out myself, basically find the 2 pair - ensure they are wired to A+ A- as one pair and B+ and B- as the other pair. If it still doesn't move swap the polarity of one pair.

Have you reached out to Shariff? He was pretty responsive to my requests (usually just a few hours). I can take a picture of my rats nest / wiring if that helps....the pictures here are before I was done.

New follower: Have purchased same DMC2mini - got it all together but issues with no movement at all.
Using the mach3 board and software... Not sure if your familiar with long mill - but have put 2 of them together with
no issues - work beautiful... Any ideas what might be the issue? Seeing a lot of issues with mach3 -- Any improvements would be great!
Thank you

Mine had no movement just hummed here is what he told me to correct. The humming sound means the motors are wired wrong - double check the encoders are wired correctly (the color coding at the green plugs) and that the motors are wired correctly (you didn't solder any extensions wrong or wrong order at the green plug).

If all three are wired ok and all 3 have this same problem then the issue is that the encoders are wired wrong internally. Basically the manufacturer has sent us some motors and extension cables that have different pinouts.. You will need to unscrew the top cap of the Z axis motor carefully (don't damage the fragile encoder wheel), and use a multimeter to carefully check that EA+ at the encoder goes to EA+ at the motor driver, EB- at the encoder goes to EB- at the driver.. etc. Most likely you will find that the blue and white or the green and yellow wires need to be swapped.
