How to select the right micro step resolution
« on: May 03, 2017, 05:07:30 PM »
Hi there

I need help on selecting the right micro step settings for my machine.
Any recommendation is highly appreciated.

I have two different Pinion gear for my steeper motor, which I place directly on my Stepper motor, and then on my rack. (I need to select the best option from these two pinion)
  a pinion with 13 pitch each at 7 mm  13*7 =91 mm
  a pinion with 22 pitch each at 7 mm  22*7 =154 mm
I also have a 4.5 N.M  (637 OZ-In) 2 Phase NEMA Steeper Motor ( LeadShine)
I also have a M880A (LeadShine) Driver

What would be the best Micro step Resolution Selection for me.

all I require is a smooth motion, with max speed of about 5000 mm/min, and off course the highest possible torque.

I am not familiar with LeadShine Drivers.
You do not say if you are using Mach4 or Mach4
You also do not say if your table is heavy or light.
We use 10 MicroSteps.
The more depending on all the above generally make motion smoother and more accurate with the MPG.
Our Router Table can run at 5000mm/min but run it at a max of 4000mm/min.
It has a heavy Y and Z and even though we have large ball rails we really needed two per side to run flat out on carving.
We use 1200 OZ-In on X/Y and 720 on Z and A.
We run this with Mach3 and Smooth Stepper.
Basically you need to get the steps per high to get smooth motion if using a smooth stepper.

My recommendation would be 10 microsteps.

There is good information on steppers here http://www.geckodrive.com/support.html/
