I thinking to add limit switch in travel track, below is some ideal and obstacle: 1. change GX16-4 to GX16-7 in both electronic enclosure end

2. install limit switch at travel track

3. Modify python program

4. Modify teensy program to allow add command send motor to limit switch

step 1.), 2.) I can do easily, 3.) i will make modification at webservice project instead of ARCS,py.

Biggest challenge for me is 4.) whic is something I not confident to do, worry it break many thing and cause unrecoverable damage.

So far any of you good in the existing Teensy and able to help up?
