To make a long story short(er). It started when I wash hooking up the basic things needed to get my oxcnc moving.

Started with this;  https://www.youtube.com/watch?v=9u8CvoVQZXc   very odd movement, same with pendant or no pendant, it doesnt move cleanly.
Checked other axis, they wont allmost budge, but they are easy to move by hand.

Then I checked further, removed all things keeping a load on the steppers, this is what happens now

Checked drivers, tried 1/2-1/4 Microstepping.

Thought maybe I did a booboo on the cables, but A+ A- B+ B- seems to connect to where they should
So I checked the motion controller > driver cabling, A Ok there aswell, connected as shown on diagram  + alarm,  




not sure if wiring this wrong might give me the erors I am having, as a final trial I will be making new basic cables just like this diagram.  



Any other final ideas would be awesome :)

Hi,
from the sound of the stepper on your video I would have guessed that the signaling current to the stepper drive is
marginal/not enough. Can you put an ammeter in the DIR line and establish what the signaling current is?. From the specs
it should be at least 10mA.

Does a multimeter work for this?

Just measure pin to gnd when trying to move?

Hi,
no, that measures voltage, you want to know the current.....current s responsible for the photodiodes light output
in the drives optocoupler. With insufficient current the light output decreases markedly then the phototransistor
won't switch or saturate like it should.

If your multimeter has a DC current measurement range, that would work. Remember when your multimeter is in current measuring
mode your probes are almost shorted together....if you forget and try to measure the supply voltage to earth say then you'll pop something.

I have never measured current before, but the MM can do it.

So just insert the MM in between the connection, should I just leave the driver connected and put the MM in the circuit between them then?
