We have been running tests all day. We have a ratio of 2.5:1 now. We have been playing with switching between the two drives. We just ran a test with the y and z swaped and without the spindle mounted up and it ran ok however we then ran the same test with the spindle mounted and it tripped the same driver however that driver is on the y axis so looks like it may bea setting in the driver? With a posable link to something else?

Charlie your all cocked up on the settings both on the drives and in Mach3.
You have the amps set wrong on drives because your using RMS settings not peak so they are getting too many amps. This will make them get hotter than should also you have the stand by current set to off so they will get hot when stood still.
So set up Dip switches like this and then try.
1=OFF 2=OFF 3=ON This will give 4.6A which is slightly higher than motors are rated and normally I'd say use next lowest but in your case it won't hurt for now. Thou I would set it correctly in protune at first chance.
4= ON
5 /6/7 Leave as set for now thou I would normally use higher than 400 micro steps for smoother motor movement. But you have the steps per set wrong in Mach3 which i'll come to next.
8=ON
With Mach you need the steps per setting to 200. This is because you have applied a ratio and now your affective pitch as gone from 5mm to 2mm per Rev.
So 400 / 2= 200 steps per millimeter.
Try these new settings and see how goes.

hi dean
sorry the picture I posted was when I still had it with the 2:1 ratio it is now set at 199.98 or something around that for the 2.5:1 ratio (this we done through the calibration function in setting on mach)
from my reading of the leadshine manual on page 14 from what we can tell it is saying switch 4 should be off for reducing the idel current?
since we re auto tuned the motor it has not yet stopped again but will adjust these setting once clear on them.
best regards

hmm that's interesting that it seams to suggest the opposite very odd! will try switching the settings according to that!
Many thanks
