Hi, I am really new here!

Please... may some of you help me to calibrate my homemade machine?

Next is what I have:

X Axis (2 Motors)

2- 1/2"-10 Acme Threaded Rod, 1/2" Travel/Turn, Right-Hand Thread, 5 Starts
2- HT23-280-8 Stepper Motor, 280 Ozln, 1.8 deg/200 Steps/Rev
2- SideSteps Drivers (Full, 1/2, 1/4, & 8th microstepping Resolution)

Y axis

- 3/8"-12 Acme Threaded Rod, Right-Hand Thread, 1 Start
- HT23-400-8 Stepper Motor, 400 Ozln, 1.8 deg/200 Steps/Rev
- SideSteps Drivers (Full, 1/2, 1/4, & 8th microstepping Resolution)

Z axis

- 3/8"-12 Acme Threaded Rod, Right-Hand Thread, 1 Start
- HT23-400-8 Stepper Motor, 400 Ozln, 1.8 deg/200 Steps/Rev
- SideSteps Drivers (Full, 1/2, 1/4, & 8th microstepping Resolution)

Questions:

1.- Motor Tuning Configuration for each. ?
2.- Whats the best Microstepping Resolution for each?

I will really apreciate your help, thanks!

You have to break the calibration into smaller steps. Since I don't have your machine in front of me I can't give precise instructions. Secondly, I don't have your drivers.

A1) motor tuning:
You need to follow the manual of your driver. Then ask a question if you don't understand a step in the manual.

A2) Microstepping:
This feature makes your motors run smoother at very low speeds (RPM). The higher the number of steps the faster your software needs to pump them out. So you may have a case where the highest setting doesn't get the IPM rate you want. All these options have trade-offs. "Best" is debatable.
So just start with something, say 1/4.
