Right so!
Heres the latest... I could still see that Y axis appeared to have a mind of its own . Sometimes would go , then it would stop.
Wired the motor direct to the driver with no plug in the line -- No better.
Found that Z axis would jog up , but not down. So changed the driver and that cured that problem.
And lo I now find that Y axis is working fine too WTF
Since then I have run two cam programs , the second quite a long one , with no fault. So why?????
Why should changing the Z driver cure a problem with the Y motion.
I am beginning to think that CNC is a black art which I have yet to master.
I also wonder if I have got some cr@p drivers .
Which drivers would you guys recommend ?
Is it worth paying for Gecko?? Advice appreciated
