General Mach Discussion / Re: Continually incorrect thread pitch

The wizard only checks to see that the acceleration and max velocity are within your configuration settings for your motors. And warns you if not. it doesn't change the feed rate. Look at the code ( better yet change it over so that it's generating a G32 and you will see what i am talking about.
So you slowed the speed down, the contoller then was able to compensate the feed rate based on a slower spindle speed. SO the feed per revolution was correct for the feed rate.
You need to fix what / where you are getting the index pulse from so the rpm is correct to Mach.
It is not Gcode problem, it is not a Mach / threading problem, it is bad rpm input to the program.
