G02 and G03 moving wrong direction
« on: March 04, 2015, 11:37:40 AM »
I am running Mach3 R3.043.066 in turn mode.  Using  a Mach3turn profile.  The program is generated in BobCAD V23 lathe using supplied Mach3turn post processor.

The arcs in both G02 and G03 are cutting in the opposite direction. The code is attached below.  These arcs are cutting from the  correct arc center they are just cutting the wrong direction.
Anyone had  this problem?

Have a read of Page 9 , "Mach3 Turn - ARC Motion" write up which you can find in members doc's.
The following is a link to the write-up.

RICH,
THANK YOU VERY MUCH.  I JUST DOWNLOADED AND WILL READ AND SEE WHAT I CAN LEARN.  FRUSTRATING PART IS I CODED A FILE TWO WEEKS AGO WITH WHAT I BELIEVE TO BE THE SAME SET UP ACROSS THE BOARD AND IT RAN FINE.   I AM SURE I TWEAKED SOMETHING THAT HAS CAUSED THIS.
THIS FORUM HAS BEEN WONDERFUL TO REBOOT MY BRAIN WHEN IT IS LOCKED INTO A LOOP THAT DOESN'T CUT RIGHT. OFTEN THE PROBLEM IS SO OBVIOUS THAT I DON'T SEE IT.

THANKS,
ARUMINAT

I had the reversed arcs box checked in the Turn Options tab of the Ports and Pins.  May have picked this up when looking ath some other profiles for slant bed lathes and accidentally saving the settings.  Either way got it fixed thanks to helpful members of the forum.

Glad you got it resolved. It's the little things that can drive one bonkers!
