Newbie here.  I am setting up to run my table top router for the first time using Mach 3.  I loaded my first G-Code and I am not able to get the program to run.  I am getting a message that reads "Radius to end of Arc differs from radius to startline 23"

Can someone please help this newbie out?

Change the IJ mode in General Config.

I'm having the same problem.
I don't understand what mode to change in config.

Hi, Eddie

This is probilly what you need to change or put a G90.1 or G91.1 in the top of your G code file.

Hope this helps, Chip

Try taking a look at the ACR Motion wirte up in Members Docs. It's for a Lathe but it covers a lot on arc's info.
