Hi to all
I have this homemade plasma CNC that was working alright. Suddenly the x axis started to miss steps and then stopped alltogether. This now happens regularly but sometimes without stopping, only missing steps. I changed the motor, no good. I swapped over the X and Y drives but the same motor still has the problem. I changed the transistor in my buffer circuit, no good. I changed back to the motherboard LPT port instead of the auxiliary one that I had been using, no good. I installed KCAM software instead of Mach3, the same problem. I reinstalled Windows XP, no good. One consistent thing seems to happen though and that is when the y axis has moved about 25cm, the x axis starts to show this problem. Apart from calling in an exorcist, can anybody tell me what could be wrong that I haven't looked into yet.
Motors are 18 kg.cm chinese
Drives are chinese
Thanks guys
