Hi All,
I have a x3 and have converted it with a syil converstion kit. The first time I got it running it didnt last long till the GREAT chinese p.s.u blew up. Hugh of Syil U.K promptly replaced it under war with two meanwell p.s.u's. anyway, I reftted everything, started it all up and it worked fine. I switched if off then on again and all the steppers were making horrible stalling growling noises. I disconected the computer and just ran one axis at a time. each axis would exibit the same problem even when not connected to the computer - you can just see the stepper moving on its own accord ever so slightly. The green led on the driver would flash once every second.
With out any of the axis ribbon cables plugged into the controller board and just power applied to the stepper its fine. Its almost like the controller is sending its own rouge signal to the stepper drivers..........
has anyone got any ideas? its not the power to the controller board as its stable. please help Im at witts end! many thanks
