Sorry its been so long since i last posted ;-) To busy cutting things out. I had a job for a school. Knowing that sometimes i would loose my Zero Setting due to interference. It was only caused while using a router or something that sparks a lot on the comutator. Most other jobs i have been using i high speed drill which did not give me problems. After i screwed up the job i had to fix it and sort out the missing steps. Been in the tv repair business i started tracing the fault. 1st i twisted the bi-polar wires to the motor. No Better 2 cut out a complete filter circuit from a Sony TV & placed inline with my supply. No Better, 3 Earthed the Machine,PC & Control Board, No Better, Last ;-) 2 x 10 nf caps 1 on the input & 1 on the step control of the Picstep Boards DOWN TO GROUND. I hope this helps anyone having similar problems. Now I can frigging use my welding machine on the same supply and my motors DO NOT MOVE EVEN 1 STEP. Good luck all.
