General Mach Discussion / 4th Axis Steps per Inch?
« on: June 12, 2010, 11:44:57 PM »
Hi Guys,
Im running a dual spindle router with two 4th axis rotaries. Everything seems to be working fine except one major detail.
Determination of steps per inch for the rotaries....
There does not seem to be a constant steps per inch, to maintain accuracy, for every cylinder I turn.
I ran a test where I turned several stepped cylinders. There were 6 steps in the stepped cyliinder. each bigger than the other by .125 or .25.
If I was able to determine steps per inch to make one cylinder accurate, the others would be off.
and this carried through all cylinder tests.
Is there a setting somewhere in Mach3 that is controlling how mach interprets or translates, to make a single constant good for all geometries?
Thanks in advance.
