Not fast enough! 80ipm reliable rapid moves which was a little disappointing. Got some resonance which isn't helping things.
Only have 3000rpm max spindle so limited to around 20-24ipm cutting with a 8mm 3 flute anyway (esp slotting).
If it makes any money it'll be spindle and servo upgrades first.

This is where I'm glad I went overboard for Nema34's on my PM25 clone.
At 400rpm (2000mm/min) the torque figure is almost identical to the Nema23 motor from a similar model line.
When it comes to acceleration though it's a fairly big difference so far.
Haven't got round to do that much testing yet with tuning to find it's stall point.
