Mach3 origin off on a circle
« on: July 17, 2021, 08:49:43 AM »
For reference, I'm using Mach3 version R3.043.062.

When I draw a simple circle with the center of the circle at origin at X0, Y0, Z0 and load the G-code to Mach3 on my engraving CNC the center of the circle is no longer at the X0, Y0, Z0 coordinate.   I can run the same code on my Tormach which also uses Mach3 and it works correctly. If I draw a square in the same position, it works with no trouble. 

I've been using Mach3 for better than 15 years and never run across this before.  I even removed and reinstalled Mach3. 
I thought about trying a different version of Mach but I'm running a SmoothStepper board and it calls for this version.

Here's a copy of the code:
N1 G00 X0. Y0. Z0.1
N2 Y0.75
N3 G01 Z-0.02F5
N4 G03 I0. J-0.75F30
N5 G00 Z0.1
N6 G00 X0 Y0

I've attached a picture of Mach3, note the origin of the circle in the tool path window.
I'm really stumped on this one.
Any ideas?

What do you have in your Initialization String (Config. page) ?

Initialization string has G80 in the space.
