6040 finally packed in!

Thanks again Mike,

Would these work the same as mine?

I notice they don't have the slit/hinge running along the width like mine.

Let me know if you ever need something cut Mike, I owe you one!

Cheers,
Kevin.

Hi Kevin
That's a very kind offer.
The coupling in the link locates and is locked with a grub screw, yours just has a different clamping arrangement so it will be fine.
Your coupling will have sheared for a reason, what you need to do is check that the gantry isn't binding for a start, but i would suspect it's probably a slight misalignment of the motor and ballscrew shafts causing the coupling to flex on each rotation and eventually metal fatigue results in a break.
While your waiting for your coupling try and align the two shafts as best you can, if possible shim the motor to suite.
Good luck
Mike
