Hi Gang. This is my first post, so here it goes.
I am using Bob Cad to write my code and running it on a new MechMate router that I built.
When I load the code in Mach3 it shows square corners on a part that I am cutting but when it is run, it puts a radius on three of the 4 corners. The first corner where the design starts is ok except for the fact that I need lead in

OK, I used the search function and found CV mode in setup. My new question is it best to not use CV or what settings will allow me to get good results without radius from right angles.

The size of the radius is directly related to your acceleration settings. The pic tells me that your acceleration is pretty slow. Try getting your accel faster, even at the expense of some top speed if you need to. Accel is usually more important to good machine performance than top speed.

However, you'll still get some rounding, even with faster accel. What you can do, is go to General Config, under CV options, check stop CV on angles >. Try it at 89 or 90 degrees.
