hello i'm new to this and have recently been using my new plasma table and I went today to try to cut something out and followed the process from designing in via cad, importing as dxf file and then uploading into sheetcam to convert to G-code. When uploading g code into mach 3 i got a code on the bottom that said "Bad Character used block = 0), at first i thought it was just the g code i had just made but it does it with existing g codes that i have already cut and saved, please help me out thank you

pls post oene of those G-code files.

Not sure how to add a photo of the g code to this

You need to attach the Gcode file (not a photo).
