I'm looking for Postprocessors for Partmaster Lathe, namely:
Linux CNC Turn Radius
Linux CNC Turn Diameter

Mach3 Radius I-K arcs
Mach3 Radius R arcs
Mach3 Diameter I-K arcs
Mach3 Diameter R arcs

In in the 'trial' period for Partmaster and my posts have inverted arcs in mach and I haven't been able to locate posts for Linux CNC.

I'm also brand new to Linux CNC and have set it up (dual boot) on my little lathe. I am having nightmares with Pwm settings, I've tried loads of values in PWM frequency and can't nail down a good power curve. Specs: Sherline 4100, KBIC motor control, C11G breakout board. Linux CNC runs very smoothly on this machine and I would sure like to use it but I need PWM, a spindle speed display, and perhaps a better way to implement backlash compensation, if I put the values in the 'INI' file it gets overwritten when I rerun stepconfig wizard. (LAME)! Any help from someone actually running a similar setup PLEASE!
