OK, I grounded the shielding for the steppers (on the TinyG side only) to the chassis of PSU and disabled all switches (xsm, ysm zsm and asm; they were all set to 1 previously, so I don’t think that should have made a difference). I also took out the transmit delays.
The spindle I’m using it the Sherline motor with a 10,000 RPM pulley upgrade.

Yes, the code runs fine with the spindle off.
I even tried moving the board a few feet further from the motors and still no luck.
I’m really starting to suspect the janky wiring in my apartment building may be part of the problem. It’s a pre-war, Art Deco building and almost all of the outlets are only two prong. I’m running both the board and the spindle off of separate extension cords to two of our only outlets that are grounded however and still having the same problem. My next step may be purchase a power conditioner and/or put the board in a metal enclosure in the hopes of getting some Faraday cage protection.
As a point of interest, when it froze up this time, I uplugged the USB so that CoolTerm would unfreeze and when I plugged the USB back in and told CoolTerm to reconnect (the spindle was off, but I did not reset the TinyG) and sent a G28 command it ran several more lines of the original text file before executing the G28. Weird. Don’t know what to make of that.
OK, this looks promising. When I read the settings from the TinyG, enable_xon_xoff was set to 0, so I set it to 1 and turned it on in Cool Term also. Now my settings report:

So do I need to do anything with these?

Thanks for the awesome help so far, you guys have made my life vastly better already!
