Hi All,
I have installed Mach3 and I was trying to move my stepper motors (from HPLJ3) and drivers made with A3977 (like those from
www.pminmo.com or CNCZone ).
I have configured and it seems to "work".
The problem is that motors are not spinning smoth (I don't know how to tell you because my english has only few words) sometimes are stucking for a very short time and after that they are continuing to spin normally and some other times are speeding up more than normally.
I have looked with an oscilloscope on parallel port and I have seen that the computer is giving the step signal in this way.
I have started Task Manager, I have ordered tasks after CPU time and I have seen that when steppers where stucking in the same time top 3-4 processes where changing between them. I have killed some processes wich I have seen that where consuming some processor. The situation has improved a little but not enough.
Could somebody tell me if this is normal and this is the way wich Mach3 normally works ? What I should try more ?
Regards,
Daniel
