Hello, this is the second time it happend, i had to reinstall Mach3 again and i don't want do more.
When i scroll Gcode, in the toolpath i can see the gcode line istruction in the toolpath evidenced with a white line, same during program run mode.
But now I can't see it , I don't have change nothing and I don't know how to fix it without reinstall all.....anyone can help me to fix it?
I put a picture to show what i mean:

In Mach 3, go to the Config tab and select 'ToolPath from the list. Take a picture (cellphone) of your settings, then try my settings (pic below) and see if it solves your problem.
