Making up a simple little program and got this error in simulation:

'MW_CC_STOP' is missing
Command:MW_CC_START MW_CC_CONTROL MW_CC_LEFT D0.000000000

I was milling a profile with Bobcad running the cutter to the left and using G41 as well so I could adjust the finished size if needed and the error comes up. It backplots and posts ok but it errors in simulation. If I take out the G41 it runs.

For this program it doesn't matter much but it would be nice to know what these cryptic errors mean for times when the program is much more complex.
