I notice on stepper charts for speed vs torque that the bigger the motor the
lower the
RPM at max. Looking at the Nema 23 STP-Mtr-23079 from Automation Direct the
Chart stops at 1350 RPM.

Will the steppers go faster or is that about as fast as a 276 oz-in holding
torque,
2.8 A/phase, 1.8 degrees / fullstep (200 steps/revolution), NEMA size 23 motor
will
go?
At 1350 RPM provided I can have low enough friction to go that fast and a 10 to
1
pitch screw driven 1 to 1 from the stepper I can get 135 inches per minute,
right?
How cricitical is the acceleration of the motor to not loosing steps?
In stepper_inch.ini the MAX_ACCELERATION = 20.0
Is that number inches per minute?
The intergrater manual says it is in user units per second per second. I don't
understand that, can anyone say that in common talk?
My thought is to use the Xylotex board with the above motor for X and Y and a
much smaller motor for Z again this is a portable plasma table...
Thanks
John
