PP on non-tormach isn't so hard. Most of the hacking has been done. My novakon has been running pp for a yr and a half. It's been flawless. I can rapid ea axis at over 300ipm or combined axes at over 500ipm- on steppers! I can rigid tap too thx to the novakon servo spindle.

There really isn't much Linux involved at all. Most of the adjustments are made in 2 files - the .hal and the .ini file. Once u have it set - you are done.

I commend tormach on a wonderful piece of software. It has changed my milling experience for the better.
