One more rapid test.
This isn't a baseline test with Mach 3 at the minimum 25000 Hz kernel speed like before.
I ran a cable to a good PC and jumped the kernel speed to 45000 Hz.
With the driver at 1/8 microstepping, 300 IPM came easy with the column still on the table.
Good enough for me.
Here are the electronics used.
570 oz/in Nema 23 Stepper motor, Keling KL6050 driver, 48V.

Motor tuning settings - Steps Per 8000, Vel. 300, Accel. 60.
Also shows the motor on the left side of the table as an option.
