abnormal condition?
« on: June 16, 2008, 01:53:33 AM »
I keep getting abnormal condition when running between G91 and G90 . Nothing abnormal about it, been programming this way for years on Mazak, Gidding Lewis no problems. Also have problem with G03 sometimes I have elliptical holes off by .015 in the x axis only. I am running precision no backlash ballscrews not leadscrews. I have checked for binding and missed steps came up with nothing.

Here is my simple program for boring a hole that on occasion messes up.

G90
G01Z1.0F25.
X0.0Y0.0
Z0.0
M98 P1 L15
G90
G01Z1.0
M30
%

O1
G91
G01Z-.065F15.
G90
G01X.343Y0.0
G03X.343Y0.0I-.343J0.0
G01X0.0Y0.0
M99

Thanks

Will leave the code to some of the G-Code Gurus.

Have you checked your backlash with a dial indicator?
