So i had to buy a new, used pc, it is windows xp pro. Same as my other was except for the pro part. I installed mach3. I instaled the factory settings from my machines cd. Machine should be set up exactly right just from that. I press jog. Machine jogs every direction plus a axis turns perfectly. Spindle turns on, life is great! So i load a program which i have cut many times. Tried others too same results.i hit start, The machine starts up, it moves to the beginning of the cut....and then it just sits there.😡😡😡. Dro is moving but not machine. I can hit stop, rewind, the machine will go back to o,o,o. So clearly the machine and mach are connected. I tried installing about 10 different versions of mach3 and every time same results.
