Hood-
Sounds like I'm making a trip to the shop this morning. I am very anxious to have this resolved. I'll double check the led's, but I am nearly certain that to the right of the E-stop button (near the bottom left of display?) there is an led that indicates CV mode, and has been lit. I've only been doing this for about 3 months, and this is all by memory, so I may backpedal if I am wrong. I'll also check for the G61. If it's there, I'll nuke it and run a test.
Chaoticone-
A selected bezier curve is quickly converted to arcs with the dialog 'Fit Arcs to Vectors.' In most circumstances, I usually don't bother being that precise before I export. The G-code Arcs (inch) (*.tap) export format actually does it for me. It does a great job without the manual conversion step. Unlike many of the folks here, I don't need extreme precision. I do signs, and the objects I tend to cut are quite large. I haven't run across a problem with too many lines of code or anything yet, so it hasn't been an issue. Is there an advantage to fitting to arc before exporting? Am I missing something?
