It's begun....

[Washout]

Hi Michael

Sorry I missed your reply - I'm pretty sure I'm running the steppers at 68V (that's the output voltage of the PSU).

Those are some pretty hairy speeds you're getting on your machine and I'll be very happy to get near that.

I also had some bits arrive today:

a. some components to brace and tension the belt between the two ballscrews (and support the "wobbly " extension. I had ordered these anyway so will try them out, as I redid the second ballscrew alignment and I must have missed a step in my haste and it was well out (2mm or more). Chances are that's where my overheating stepper was coming from and gantry binding.
b. Also a spare M752 came from ebay (China), so will use that as plan b, should a. above not work out. I'll also likely need a custom motor mount as the T-slots don't line up with the mounting bolts on that side of the machine.

More as I get on with stuff.....
