I’m having some trouble with G code processing it through Mach3.  When I load the code it seems to go through all the lines and then get stuck so I cannot run the program. I would appreciate any help someone can provide. I’ve run into this once in a while and I’m always puzzled by it. I’ve tried moving the lines slightly in the dxf file, then regenerating the G Code in BobCAD.  Then load it in Mach 3.  Sometimes this works, other times it doesn’t.

Could any experts comment on whether it's how my BobCAD is programming the small radiuses in the geometry?  I don't know if I need to change a setting or how to approach getting this fixed. Probably spent about 25 hours on it trying to figure it out. mike@customcuemaker.com is also a good way to reach me, thanks in advance.

Try removing the command K0.0001 from two instances within your GCode file.

Basically your GCode is not well compiled. (It is improtant to have valid entry and exit moves when using G41).

Interesting.  I removed those instances in a short piece of code and it seems like Mach 3 is MUCH happier.  Thanks VERY much!!

Any idea why those lines would have been added?  I'm using an older version of BobCAD, is the software itself flawed?

Any idea why those lines would have been added?

Probably the settings within BobCad ?

Well I just ran a full program removing all of those key references and everything seems to be working great. Cannot thank you enough!

I am pleased that you got it working.

the K parameter is usualy only used if you are NOT working in G17 plane (G18/G19).
