This is the top portion of a program done in cut 2d and using the mach 3 post. When I try to run the program I get the error message:

"Bug unknown motion code line 5"

Also the spindle speed is slower than 4000.

Anyone have an idea what is wrong?

Thanks,

Try
N50 M6 T1

Also
N60 G43 0
should probably be

N60 G43 H1
if you want to use tool length offset.

Thanks Gerry,

Tried what you posted N50 M6 T1

and still get the same error message.

Thanks,

Gerry,

Changing to "N60 G43 H1" did the trick. Is there a way to change the post in Cut2d so I would not have to alter every program?

Thanks,
Ed

There should be a line in the Header section that looks like this, with a G43 in it.

"[N]G43[ZH]H[T]"
