Cor,
Don't spend money on a card wthout looking at the pulse else you may just be wasting your money. See if it's a 5volt output as Jeff noted.
This is interesting because as i write this,my friend just finished putting together a pc and guess what! Yep same thumping sound as yours and i know it all to well. That said.
I went over and did an install, config, etc and his steppers worked fine. Today when he went to use it / next day......bad pulses. I fooled some and reinstalled the driver and the machiine worked fine until i changed an acceleration setting. And back came the bad pulses. Could not fix itno matter what i tried as i have been down this bumpy road before.
So you are not alone, Cor, the only difference is that for myself after manny hours of screwing around i just bought a SS and did away with the problem.
What I have posted before and will say again is that "YOU JUST NEVER KNOW if A PC WILL WORK THESE DAYS".
BTW my friends old slow dead dog 400 MHZ machince ran his machine just fine and no problems ever.
Stay tuned,
RICH
