Settings lost

Hi all! I’ve got a late version 1000x1000 that I upgraded to lead screws (phantom kit) and worked wonderfully for the past two years. Today, after a down time period, I restarted my computer, and uploaded the new driver. Not sure if the driver upload is the problem or a coincidence. My settings have been lost (I am NOT a programmer!!!) and now my motors travel for less than the commanded distance. Homing timed out and said to check for interference, and 1" is much less than 1" of travel. Would anyone have the $$ settings for the Phantom kit, or if Phantom still comes around, maybe he wouldn’t mind reaching out to me? help! please! work to get done! Or need someone intimate with the $$ code to help me get it back to working?

You can easily change the steps per mm with an accurate rule or caliper. How to change the GRBL settings on the V-Carve - Software - Inventables Community Forum
