Scratch all that, I got it to load a file. I don't know how I ended up
with all the wierd estop messages and such.
emc_mode auto
emc_open with the filename seems to work to load the program
I think i didn't set the mode to auto previously and went down a bad
path of error messages.
Is there away to ask axis to update it's preview gui from the tclsh and
emcsh?
Thanks!
