So, I did a 15" x 12" 3D carve this morning . Roughing with .25 EM went fine. Finished with .125 BN. I was running short on time, so I boosted up the feed rate, and of course snapped the bit got everything reset, now GSender thinks the file is in mm, not inches. I tested the the Gcode and everything seems fine, but when I run the outline, it does it in mm in the lower left of the file. How can I fix this?
Not sure if this will help but, G20 sets grbl to inches, G21 to mm. Is one of those in the beginning section of the file? Maybe try typing G20 in the console and then running the outline. If you post the g-code it might help someone to help you.
here are the last 50 lines of code

You might want to check out the settings where you exported it from because all those G21’s mean millimeters. Not sure what software you created it in but it looks to me like it was set to millimeters somewhere.
I’m just learning what all the different codes do using this as a guide.

@Dan1 Dan: You will see that I have deleted your cross post in the gSender category. As you have found, using UGS does not solve your problem, so clearly it is not a gSender issue.
As @_Michael (Michael) has pointed out, the problem is your gcode. It has a G21 on several lines in your posted excerpt. Those codes tell gSender and UGS to move in metric distances. All gSender and UGS can do is execute those commands.
Thanks Michael. Not sure how, but vectric now exports the gcode for inches in mm and the gcode for mm in inches.
@Dan1 Take a look at the post processor you are using in VCarve. Make sure that you have set it to grbl inch.
@Dan1 that’s a new one
Been using Vectric for a while and never had that issue. Check with Vectric support. Did have an issue with UGS m&m but never with gsender
@Dan1 Given that you have not updated your issue for a couple of weeks, I will assume that you resolved your problem and I will close this thread.
