Also if you install from sources all major updates are tagged:

The "Limit Hit", is it always on or do you just occasionally get = it?

I flashed the grbl with the 127.0.0.1:4444/flash_firmware
<http= ://127.0.0.1:4444/flash_firmware> link.


Jamie and I were using 12.06? i think? today with no problems. I had a
system crash and need to get my win7 laptop setup to cut.
