How do I configure the A-axis settings?
« on: February 22, 2019, 10:56:19 PM »
What do I need to do in order to configure Mach3 to know when the rotary axis has done a full 360 degr. rotation?

Its been awhile but in the general settings you check
or uncheck Rot Roll Over. There are other settings,
so ask away.

I need also to know which values to set in the Motor Tuning and Setup/A-axis motor movement profile?
My rotary table requires 72 rotations from the stepper motor in order to move 360 degr. so what do I need to set in "steps per". and the other windows there?

I use the Gecko G540 as driver for the stepper motors..

Lets see if the old grey matter is still working.

It is best to set your steps for a 1 degree movement so if you need to move 72 motor revs per 360 degrees then its 72 X 200 steps (or what ever your steps per 1 rev of the motor) divided by 360 this is your steps per 1 degree which would be 40

If you turn off 'roll over' and 'short path' then you can command A720.0 or A1440.0 and it knows its to do and done 2 revs or 4 revs of the axis, it will also do 2 or 4 revs back if you command A0

I knew that someone (with far more knowledge) would
jump in and list all the details.
Thanks

I tried the settings that already was in the config. page and after turning the rotary table a full rotation, I calculated the right setting to be 400 steps per unit, and it looks like that is the right one, but I donĀ“t understand how this number could be the right.
Does that mean that I have 2000 microsteps in my drivers?

I think the 540 defaults to 10 micro steps which would give 2000 steps on a standard 200 step motor.
