M8x40 did the trick, gap closed, put an arrow on the pic in case you couldn't see where it was

Did you drop some loctite in the gap before closing?

Because if it gets the faintest jiggle it will never close that sweetly again :nope:

Good idea, but then I'd have had to clean off the RTD and I was rather enjoying putting it together :naughty:

If I take it off I promise to Loctite it

Kip, I don't know how it compares to driving the handwheel because I've never tried that. If I had to guess I'd probably plump somewhere between amazing and freakin' miraculous

Curious.

I wound up the feed rate on that hybrid stepper and it would do 18mm/s but clacked out at 20 mm/s

I disconnected the Y axis to get some spare Amps then switched the hybrid peak current from 1.9A to 4.2A peak.

Wouldn't do 18 mm/s anymore :nope:

Possibilities...

The cable on the Z is altogether too long and it's having problems controlling the current.

The stepper driver can't actually cope when you increase the current.

I imagined it :heehee:

So, any ideas what driver/PSU combination I need to shop for?

However, 18mm/s is a lot better than I had before so I made new plates to fit them on the X and Y. Stuck a fanciful strain relief bracket on the X so I can bolt the flexy trunking to it.
