Hello Alex, maybe my English has become rusty those last 40 years without much practice..., anyway: I am using stepper driver boards of the 90'ies. So far, using the software provided by their producer they were running all right, but rather weak (too little amount of current) and the software is unflexible. Now, with EMC2, rest of the setup unchanged (except, of course, for Linux instead of DOS), the steppers don't perform right because according to Jeff Epler, the pulses at the printer port are too short to drive the motors. Or the other way around, the old driver board seemingly does not adjust pulse length and therefore the motors don't get enough energy during the pulse to move one step correctly. That's my diagnosis.
As I understand, modern driver electronics care for sufficient pulse length independently of the trigger from the PC so the motors will run smooth again as they used to. And there came my question: will purchase of new electronics solve the problem? Apparently, because many participants of this mail group seem to use Mesa boards and it's working that way. Now, if I had new boards, I would have to adjust the system by means of stepconf - is that not right? Why do you say the parport setup by stepconfig is useless? What else am I to use, and where can I find more information? Now, I in turn got the feeling that I don't quite get it...
