and even built a "G scale" train that is gear driven and gas with
forward and reverse and the best part is that it is radio control. (G
meaning size meaning larger than HO gauge)

This can happen sometimes when scaled drawing are converted to
Gcode, some Circles become to small for the machine to drive.
You can easyly fix this by editing the offending section.

G01 Z0.0000
G03 X31.5735 Y18.3603 I-0.0446 J0.0000 < causing error!
G00 Z0.1000

change this to:

G01 Z0.0000
G01 X31.5735 Y18.3603 < fixed problem
G00 Z0.1000

Make this change in a true Text editor like Dos's EDIT
or Windows NOTEPAD.
Good Luck
