Hi all

Has anyone come accross the problem of Mach3 getting the centre of G02 G03 arcs a country mile out? I have a simple toolpath to cut out a rectangular profile. Each corner (of the toolpath) is an arc which should have a radius of around 7mm according to the g-code. However Mach3 interprets the radius to be massive so I end up with a toolpath resembling a rectangle with huge "micky mouse" ears!!!

Sorry - can't seem to figure out how to attach images code etc...

Any comments, advice would be welcome.

Cheers

Go into gen config and change the IJ mode, that should fix it.

Many thanks Graham - problem solved - strange though, havn't had this happen before... Though I have just reloaded Mach3, but can't remember setting this before.

Anyway thanks again for your quick and spot-on reply

And also don't forget your cam program can toggle this also.

thanks chad - right on the money.

I'd switched off "output arcs as linear segments" in my CAM (RhinoCAM) which meant this was the first time I'd actually posted a real arc (G02 and 3) so this was the first time Mach3 cared about this setting.

Thanks both for your help

Thanks for this thread, I was having the same problem posting from Gibbs.   Switching the IL buttons fixed that.
