Me second area where I need assistance is with CV and rounded corners. I can only get the square corner cuts I want right now with Exact Stop, but I've been warned by my MasterCAM people that it is really hard on the CNC machine. They told me I needed to play with accel/decel curves to get what I want. I guess this pertains to my question about release versions as well.
- Does the latest version of Mach3 handle CV better than my older release?
Didn't have time to read the whole thread, but two other ways to minimize or get rid of round corners with CV mode are
1) Use G41/G42. This will give you a toolpath with corners having the same radius as the tool, which gives a square corner with a rounded toolpath. The larger the tool, the more luck you'll have at getting rid of the round corner.
2) Create offset toolpaths with a radius corner the same as the tool. Basically create the comped path in your CAM package.
Both methods do the exact same thing, and if your accel is fast enough, they may work for you.
