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.
