when I run a program it duplicates to same bit 3,4,5 + times. I use inkscape then makercam and cut with mach3, where is the problem. I am new to cnc and starting to get a handle on things. I bought dxf files on ebay and made a pen holder for my machine, and am now going through and making a hard copy of all the files to make sure they will run without a lot of problems. I get about 3 maybe 4 projects to a refill. Any Ideas Thanks Chuck
