Mach3 going off course of cut
« on: December 09, 2006, 01:07:25 AM »
I drew a little part in auto cad and then sent it to Lcam..Set it all up..Looked good when it displayed..Then sent it to Mach 3..It looks good in the display..Mach will be cutting just fine and then all of a sudden it goes wildly off course..you can see the proper blue lines before and then the yellow cut course in the display just goes wildly off course,and it goes crazy with the speeds too!! The router itself goes with this crazy line forgetting about limits for speed too...What is going on here??  Michael

Can you post you code for us to look at?

It will cut all the drill points real easy and make all the circles..It goes over to the outside profile and start cutting fine...then it goes off..taking the mill with it...as the off course line is being drawn yellow on the screen,my mill screams trying to keep up..I don't know...when you line jog the code line by line it follows okay..Michael

Michael,
    I don't know. I'm no Gcode guru like some of the others. Are those leadin, out moves? If they are rapids, ( G0 ) they will ignore the feed rates and run at max. Can you post your DWG. file? Different color lines represent something. I don't know what the green means.

The outside profile is a closed polyline...the circles are just circles..The outside rectangle is set up to cut up high,so it actually doesn't  cut anything on the machine..I just made it that way because that was the piece of scrap wood I had to make this piece..

Here is the code I get for the outside profile.

i think if you used lazycam to generate the code you didn't use autoclean
