Re: Mach3 Feed changes causing deceleration to 0 first
- Thanks a bunch for the suggestion. Version .062 runs the code smooth. I had also tried Jeffrey's suggestion of adding Y and Z coords and that didn't help. It seems some versions of Mach3 have this problem and some don't.

Absolutely no jerking or hesitation or feed rate going to zero. So, now I am puzzled. There has to be something different in the two machines. I run .066 on the large machine and .062 on the laser machine. Perhaps that is it. Unfortunately, each of my machines is in a different location, so I can not compare M3 settings just now.
