    G1 move after G2 move

    Well, I have an issue that's got me lost.

    G1 G41 x.3735 y .2
    G1 y-.325
    G2 x.1235 y.-.575 r.250
    G1 x-.1235

    Mach's graphics writes this and the rest of the program out. When I run it, the program stops before it executes the G1 x-.1235 line. This happens both with the motors running and inhibited. What could be causing this? I fear I'm overlooking the obvious.

    It's probably caused by the G41. What is the line of code before the G41? ANd what size is the tool?

    Something is up because 2 days ago I cut a .140 wide slot with a .140 radius at the end of it,. That program won't run either after a radius.

    The move before is

    G0 x.6 y.3
    G1 z-.186

    .500 endmill set at. 498. It ran through the radius, then wouldn't move on the x-.1235 move

    No g42 in the program, just a clockwise arc that is cut, it cuts the first arc then Mach just sits on the x-.1235 move. As I said earlier, 2 days ago I was cutting a .140 wide slot with a .125 endmill. There is .140 radius at the end of the slot. It worked just fine, ran all the way through.

    After having the problem I posted about last night, I loaded the .140 slot program and it to stops after the first radius cut and the program doesnt proceed anymore as well. I'm baffled.

    Do you have a line with the tool number on it? Mach3 will use the diameter of the current tool, and if your not calling the tool, it could be getting a bad diameter from the tooltable.

    Yes sir, every little program I have tried today has a tool number and they are the same tool info from 2 days ago. It seems now that any program I run that has an arc anywhere in it, runs up to the first arc then wont execute the next line.
