I have been running into a problem when I am moving at really high IPM (inches per minute) using EMC2 Axis.

This image sums up the problem I was having:

Axis EMC2 was rounding my corners. I wanted it to go to that spot and then move on to the next line of G-Code. My friend Paul and I did a little research. He remembered that there was something on the emc2 list about CV problems. Where emc2 would try to keep a constant velocity.

As we researched we found out that emc2 implements “Trajectory Control” using the G61 and G64 commands.

So to solve the “problem” I was having. I told my Gcode file to use G61 Exact Path Mode. It got rid of the rounded corners I did not want.
