OK here goes my thoughts on belts after much reading.
I could probably do it, but still have trouble with the concept of how far to gear down the motor (or at all).
T will be considered gantry travel at 1 revolution of the stepper. Since the stepper can rotate at up to an arbitrary value of 1000 RPM, I would think that the pulley should be quite small.
So to figure out T I needed to put the smallest pulley available on the motor which would be 10 tooth.
THe 10 Tooth pulley has a diameter of .
617".
So
T= .617 * 3.14159 = 1.938" per revolution
A stepper has 200 steps per revolution.
1.938/200 = .00969 at 1:1 (.010 rounded) Pretty coarse, isn't it?
My 4AUPC driver has 1/2, 1/4, 1/8, and 1/16 micro stepping. This means that I can get down to
.010/16=0.0006" per step theoretically at 1:1.
This only leaves one question unanswered. Is the 305oz/in stepper going to be able to haul the 16# router plus the weight of the gantry at 1:1?
Also at 1/16 micro stepping, I can ideally get rapids of *up to*
121 IPM,. But only in a perfect world that doesn't take into consideration mass and acceleration.
Am I on track so far?
