Title: Most simple Gcode with arc problem.
Post by: ftomazz on February 05, 2007, 07:31:58 AM
Hello. I'm running the latest version of Mach3.

I have in Config/General Config set to absolute mode and IJ to incremental. The following GCode gives me problems:

G17
G21
M04
G01 X30  Y20  F200
G03 X300 Y200 I60 J34  ; <------ PROBLEM
M05
M30

It gives me: "Radius to end of arc differs from radius ..."

I added G90, G91, changed the setup to absolute IJ and everthing else I could remember ...

Thank you.

You're specifying the center of the arc to be 90,54. An arc with that center can't pass thru both 30,20 and 300,200. I don't think it will work in absolute IJ either.

Yes it is a gcode problem, nothing more.
Thank you.
