programing G3 IJ R

[Luslugger]

This code stops with an error 39. on my okk pcv-40 meldas m86. Does this machine recognize an “R”. How do I change between incremental and absolute center of the radius? When do I use each? I have a Mach3 simulator computer program that runs the code below with out a problem.

I don't have a mill programming manual handy, but the Mitsubishi lathe programming manual says R is allowed, so I assume it would also be allowed for the mill.

AFAIK, arc centers are always incremental from the start point to the center. Your example appears to be using absolute center coordinates.

Mitsubitsi has confirmed what you said. I have found my Mach3 program will run a demo program all the way thru that Mits will not run because the end points do not match. I am redrawing everything to check my points.

your vector endpoint do not match to starting point...... that's why machine stop and give you alarm.
