unfortunately, i both updated from 2.7.0 to 2.7.14, and loaded the converted INI file at the same time, so no telling which change caused the conflicts. i highly suspect the errors are from my INI file changes, so we will work with that.
all my config files are on my GitHub, here:
github.com/travisfarmer/my-linuxcnc-conf
after homing the machine, (slow but it seems to work), i intended to verify my software limit settings by jogging toward the extremes, and noting where the machine stops. i only got as far as testing axis Y (AXIS_1). the MIN limit worked perfectly, though when i jogged toward the MAX software limit, it moved a bit over 4 inches, and shut down the machine ("Joint follower error" i think).
it is extraordinarily stupid of me that i didn't save the INI as a backup, per-conversion from MM to Inch. i think i can roll back my GitHub, but i am not keen on that, just yet. perhaps some more eyes on the configs will spot something.
Thanks in advance for any help.
