Re: Back Lash on X

well with a bit of help from tom I started taking the table completely to bits to try work out the problem although the backlash issue is 100% not the ball screws, the ball screws are very very sticky. turns out the oiler isn't working which could well be the cause. there doesn't seem to be any play...

Re: Back Lash on X

is this normal?

the table moves back and forth pretty easily (and no its not the vice that's moving)

I had issues on my triac with the motor, kept tripping my rcd. Once I gave it a mega clean I've not had any issues since.

But I had smoke coming from the top of the motor
