I am trying to fine tune my machine and may end up only using a small amount of cv rounding on light gauge decorative type work, as any slowing builds the heat up fast on thin stuff, and also introduces extra dross. It seems that I have the opposite problem of most (trying to eliminate rounding), although i have some strong motors and can accel/deccel fast. I can get sharp corners, thats not what im trying to achieve. Also on decorative cutting, where corner sharpness does not matter at all.
I am ok with some corner rounding on most parts, as just a little bit will allow much better movement and closer CV speeds to achieve less dross and heating in corners, especially on thin sheet. Any way around this while still using outside offset (to produce true sized parts) and Constant Velocity (to prevent total slowdown in corners). This happens when using the outside offset feature of sheetcam to compensate for plasma kerf width, because it offsets the cut to the outside, which means the plasma cutter makes a small arc while hugging the shape in the corners, but this evidently cancels any potential to use CV and it will stay on that path entirely, instead of allowing it to cut the corner by my set tolerance to keep the speed more consistent.
#Sheetcam loop sharp corners code#
I am trying to figure out why constant velocity is not working in mach 3, and a mach technician told me that because my g code file is producing arcs in the corners instead of just a 90 degree angle, it is not doing CV.
