Rotation diameter parameter number
« on: December 15, 2008, 12:29:44 AM »
I would like to change the rotation diameter (used for computing blended feedrates for a-axis rotations) from within a G code program.  It seems likely that it is a Mach3 parameter, settable with the #*********=yyy expression.  Does anyone know if this is the case?  Alternatively, is there some way to dump parameters so I can search the 10,000+ values to find the one I'm looking for (after setting it to a unique value so I know what to look for)?

Thanks in advance.  The alternatives are workable, but ugly.

Bad assumption on my part.  I ran a program that sets all parameters from #1 to #10300 and the rotational diameter was left unchanged.  Looks like I'll use inverse time feedrates for rotational moves.
