Yep, I can jog off the limits in both touchy and Axis with the MPG

Yes, I think I do that on the CHNC lathe, but I can verify...

In that case it seems to confirm that it is because I only have one
sensor for both ends.

Yes, exactly.
Though the lathe is likely to end up with a modified Touchy, as I have
separate X and Z jogwheels and a knob to select the jog

I think "override limits" only lets you do a continuous jog. It
might allow incremental but I'm not sure.

Yes, it should be possible, IF you have separate switches for positive and
negative limit.

my old c-frame machines were all wired with an i/o box at rear of column
this box had 2 rows of terminal strips
top was in from control
bottom was out to control
terminal 1 of top jumpered to terminal 1 of bottom allowed override of
the whole estop chain on machine side ( temperature, oil
Wow - that is pretty.. Love the MPG's in the apron. Can't wait for a
video showing them working!
The K is a pain to get off of the over travel limits - but it has only
happened once when I forgot to home and jogged it into the limit. The
matsuura is even harder. You would have to remove

The motors have resolvers on the shaft extension, and then the whole
motor lives in a casting.
No visible motor shafts in this set-up:

Should it be possible to jog off of a limit with an MPG?
I have never managed to, and on my new lathe it takes a bit of
dismantling to get to the screws to manually rotate the screw.
Of course, when the machine is properly set up, this should never happen.
