Problem with offet table and circles
« on: January 24, 2019, 09:04:19 PM »
Hello all

Been using Mach3 for years now (basic user) and just decided to try and use the fixture offsets. I've always just used the default table (G54), although honestly until today I've never really looked at that screen let alone press any buttons.

So I set up a fixture for G55. Problem is now my code as lots of strange giant circles everywhere. Doesn't matter whether I select G55 or go back to G54, previously good code now has lots of stange circles.

Looking both here and Google, I've tried added G90.1 & G91.1, also changing IJ MODE under the GENERAL CONFIG tab. Neither seems to help. The exact same code also works fine on my main PC where I do all the development, but transferred back to the cutting machine PC and it goes crazy.

Any ideas?

Cheers - Matt

EDIT -> Here's the first bit of code, it goes crazy after about the 3rd or 4th G2 (code originally generated by the Mach3 Text wizard)

I tried just G90.1 by itself and not G91.1 also and that seems to work (or was it the other way around?).

Don't really comprehend what's happening, but it works.
