Re: [Emc-users] Examining g-code parameter values

[Jeff E. <je...@un...>]

You can send one or two values at a time to an M1xx script.  We ship a
sample 'M101' script, and when I entered this in MDI:
    M101 P1 Q1
it printed in the terminal where I started emc:
    M101 P1.000000 Q2.000000: put your code here

I'm not entirely sure how the variables are treated after a program
aborts with an error like "radius to end of arc differs"; it may be that
you can "post-mortem" the parameter values in this way, but I wouldn't
be surprised if the variables are reset or discarded instead.

"debugging" complex nc scripts hasn't really been on the radar.  Perhaps
during the development cycle for emc 2.2 we can begin to address this,
but I'm really not sure what form an nc-file debugger would take.
Single-stepping and examining parameter values seem like pretty basic
items, though.
