If I remember rightly, you are using ace for your g-code conversions. I have found that if I use polylines for the toolpath ie. an arc and straight line, joined as a single line, ace tends to mess up the g-code. i always test first in a cnc simulator program, and it shows up these errors. So if you are using poly-lines in your toolpaths, just select them, and Format -> Explode to break the line into it's respective pieces.
Or, you could just ignore what i said, and just make sure you test your g-code before you use it! |
