Why am I always getting big arcs with G2 and G3 codes?
« on: December 09, 2012, 04:34:22 PM »
Every time I run a gcode with g2 or g3 lines, the arcs are somehow converted into big circular paths. I can't figure out what is going on. See attached. Some of these gcodes have been downloaded from the internet so I know they are correct.

See attached.

Gcode 2------below:

N5 G90 G20    
N10 M06 T1    
N15 M03 S1300    
N20 G00 X1.75 Y1    
N25 Z0.25    
N30 G01 Z-0.25 F5    
N35 G04 P500    (0.5 SECOND DWELL BEFORE ARC)
N40 G02 X1.75 Y1 I0.5 J0 F20    
N45 G04 P500    (0.5 SECOND DWELL BEFORE 2ND ARC)
N50 G03 X1.75 Y1 I-0.5 J0    
N55 G00 Z1    
N60 X1.25

Go into config and change the Abs/Inc setting on the arcs
