General Mach Discussion / Latest Backlash Comp behaviour on circles?

« on: October 30, 2007, 08:25:35 PM »

Hi all,

Just wondering how Backlash Compensation is working when cutting circles? I have not been using the B. Comp because the last time I did it ruined a part by creating an oval instead of a circle. I was having the problem of deceleration after a change of direction in x & y at the time and was unaware of the Shuttle accel. adjustment of .05 - .1. I have yet to make this setting as I've just learned about it here in the forum. I am wondering if accurate circles are simply unobtainable with B. Comp on even with the correct Shuttle accel. settings as in 2006 versions of Mach3.

I now have a part to cut that needs the accuracy of Backlash Comp, but also need accurate holes or circles.

Thanks

Kurt

General Mach Discussion / What replaces G79 for Mach3?

« on: September 11, 2007, 05:22:27 AM »

Hi all,

I am trying to create some g-code from VectorXT for use in Mach3.
The problem is the post processor is placing a G79 before the coordinates for the drill hole. I am using an isoacv10 post.
Is there a replacement just for this G79 or is there a good Post processor for use with Mach3, latest lockdown version.

Thanks
