Hello, im new here. For a few years, cnc has been my hobby. I decided to build a plasma. I came across Sheetcam and I really like this program. Unfortunately, I came across a problem with circles. I load an svg or dxf file and the generated gcode is completely meaningless. Does anyone have experience with this as well? I apologize for my English, it’s not my native language 
Are you using the correct post processor for your machine? Each post makes code specific for different machines.
How about posting an SVG and the output gcode?
Is it an absolute and incremental co-ordinates issue?
