When scrolling through the gcode I no longer see the location of the tool in the toolpath screen (or the part of the toolpath that represents the gcode doesn't light up) like I used too, I don't see where that can be turned on or off, do I need to reinstall Mach???

What version of Mach are you using?

After I posted this I asked myself the same question and I AM do for an update, if the problem perstis after that I'll be back.
Sorry ftom not the same problem.

New version fixed it.

That did NOT fix my issue, I do have the latest ver, I know it used to work, did I turn this off somehow??

attach your xml and some code that you have issues with please.

I tried renaming the files but I keep getting this message, what do I need to do? Sorry! There is already an attachment with the same filename as the one you tried to upload. Please rename the file and try again

 Copy it to your desktop and give it a different name, like none before.
Same with ANY file, must never match a previously sent file name.

Thanks overloaded. Hope this is what you needed Hood. Thanks
