re:Re: G92 and M99 code/cncpro

hey you guys, thanks for all the heli on this subject! So far using
the subroutines way has worked out best and I am starting to pick up
on it. I will give the others a try tomorrow and report. I also don't
think the reason the Z axis moves down is due to the reason you said
smoke. Not sure, but if I did not include it in the parameters of G81
then the code would be incomplete?? Will give it try. I wonder if it
is a cncpro prob. Ballando you said this is one reason you stopped
using cncpro,,,,any others??? what do you use now?
thanks again guys
