New CNC for me
« on: August 04, 2019, 12:03:57 PM »
Ok got a dual Y Axis CNC with a Eleksmaker SE v3.1 board.
The motors are a 42HS34-1304A
When I take the gear off one of the motors and have the other unplugged, I click control laser then an up or down and the motor just does this pathetic vibrate with no real movement.
If I connect the drive gear and belt and plug both in, they both do the same vibrate.
thoughts?
If I unplug the Ys and plug the X into one of the Ys then that motor moves fine.

Also when I have it all plugged in and do the X it is opposite what I press. Left if right and right is left.

thoughts?

You know the driver is working so the problem must be the wiring to the motor or the motor. It's common for steppers to vibrate when you have the coils crossed which again indicates a wiring problem, swap any 2 wires and it should work - maybe backwards but at least it will move.

so, how do i tell what kind of Molex these use?
This is a 6 pin with 4 wires...
the plug is 11mm wide.
I have some JST-XHP 2,3,4,5 pin but not this 6 pin ones... grr

if anyone has a link to the cable done or just the molex and pins, then I can make.

The pin spacing is probably 2.0mm. EBay list dozens. Start with the motor info. While you are searching match the end on you controller.

I was able to do some tiny solder jobs and made the old ones work.
thanks gang!
