Mach4 General Discussion / Line 0: Zero Radius ARC

« on: July 22, 2022, 07:59:42 PM »

I've looked at other posts that have a similar error but none seem close enough. All I'm trying to do is face a spoilboard on my new Avid CNC router. The gcode is created by Fusion 360, very simple like mowing the lawn. It does the same thing over and over but mine stops about halfway through with the error. The only thing that changes from pass to pass is the "Y" value. I think it stops at the Y7.5179 command. Not sure why it says "Line 0".

If I try this with a nice radius at each end I get end stop errors. I'm supposed to have 49" in the "Y" direction but I'm only asking it to do 48". I'm using an Amana RC-2256 2" flycutter which is designed to do just this type of work. The parts that get surfaced look perfect. 

Please help, at this point my spoilboard looks like someone that doesn't know what he is doing worked on it. Good chance they are right.
