Cant Figure out Rotary Axis
« on: April 16, 2017, 02:03:04 AM »
Hello

I am working with my cnc machine to come up with a rotary axis. I am currently stuck on working with the A axis to have it turn accuratly.

My setup
Cnc home build 3 Axis (2 steppers driving x)
Aspire for toolpaths
Mach3 mill
Using the CNC Wrapper to convert X values to A values.
Im Sure there is something i am doing wrong.

Here is a Video and the G codes

A rotary axis can be configured as linear or angular and is defined in
General Logic Configuration under Angular Properties for the  axis.

In motor tuning for the rotary axis the Steps per are defined as
"Steps per degree" for angular configuration. If linear then the steps per degree
are relative to linear travel per degree for a cirular object ie; Diameter x pi=
the circumference and that would be the linear distance for 360 degrees.
 
You can use the axis calibration feature ( Settings Alt6 ) tab for a rotary axis.

You need to calculate the steps per for the rotary and should take into consideration gear reduction and  micro stepping,of the axis.

Velocity and accel settings are  trial and error just like any axis.

As far as the other programs read the manuals for them.
