Hello everybody,

I tried to setup my motors in mach3 and I've noticed that those are skipping steps when jogging in Motor Setup . I'll try to post a video when I get home.
The motors are not shaking back and forth like I've not connect them properly....just not moving round and smooth.
What can be the problem?

In Mach3 I started with 2000 or 1800 steps per mm , step & direction pulse set to 0 . Tried different speeds and velocity with the same result. Could it be that the pulses are coming too fast for the driver to process ?

Try setting the pulse width to 5

thank you! I thought that today... I'll try when I get home and I come back with details.

Any other thoughts?!

Do you have antyvirus/firewall or any other programm except mach3 running?

I have Eset Nod antivirus installed but I think the computer is powerful enough not to "choke" .

@ger21 Thanks! That's it !! It also works setting to 3 . Also the vibration has been eliminated.
