Hey guys,

I'm running into kind of a strange issue. First some background info. I am using Autocad to generate my drawings, just simple squares and circles to start out. I am then using SheetCam to convert the dfx files into gcode. From here importing into Mach3. According to tulsaturbo I should be using the MP 100-THC post processor. Everything looks fine in Autocad and sheetcam but the problem is when using this post processor I get some strange gcode generated when there are are arcs present. What happens is sometimes the arcs totally reverse or are much larger than what they should be; say if there is a rounded corner instead of just rounding the corner you get the opposite of that arc generated. See the image below. I believe there is something in this post processor causing this because I tried the Mach3 post processor and the arcs are generated correctly. Anyone have any ideas about what I'm doing wrong here? Thanks!
