hi, im in a pickle at the mo
it may be real simple , something like motor tuning
but i have no experience with mach, nothing mentionable in anything else either.

i'm new, so i started with what i thought was a decent setup.
it concisted of a serial control board linked to three non-chopping bipolar drivers. now this system was conected to a intelmac via serial to usb converter. this worked fine. that is it moved the motors back and forth. the proprietry software has nothing going for it. despite i was happy to see a shallow result.

after some consultation with the supplier i realized a parallel port was norm and necissary. so i purchased a neat opto breakout from the same. as it was verge colection i managed to pic up a pent3 600mhz for nothing. bargain. given the modest stats ive gone for mach2 and feel i could get comfortable.

but i'm getting nothing.

my lame attempts at motor tuning are fruitless
my configeration is a mess of (educated) guesswork
im confussed

i have been getting (when holding a jog) a shuddering of a movement, but it is intermittent and pathetic

after such a big conversion on such little exprience ive got a lot of places to look for this problem. if any one could narrow my search i'd appreciate it.

thanks
