Are those step-direction drives? The general advice in the EMC2 world is to buy totally dumb drives and do all the PID inside EMC2. Then you can tune in software, and use Halscope to watch what is happening. The Mesa 7i29 is $150 per axis (2 per card) and two of them can share an FPGA card header. So 2x 7i29 connected to a 7i43 connected to the parport will give you a very capable system which is a big upgrade on a step-dir parport system (apart from anything else you then have an extra 24 GPIO pins to play with) However, the 320X really ought to work on Y if it works on X. Have you tried a motor swap? I am wondering if there is a faulty commutator segment. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ vRanger cuts backup time in half-while increasing security.
