Hmmm…loaded the tap file in https://ncviewer.com/ - it’s a 2kb file with 68 lines. Looks messed up and incomplete.
Imported the DFX into sheet cam and generated a new gcode file - 77kb with 3,592 lines, no issues. Looks fine in https://ncviewer.com/ - ready to cut.
My guess is that something is not right with your tool settings and contours in Sheetcam - lead ins and/or offsets or something like that. I’d double check all settings and regenerate the g-code / post- it should be around 3500 lines…
Edit: here’s the post I generated from sheetcam if you want to use it: Eddie Taxi.tap (76.1 KB)
Good luck!
