Build and Intro

Regarding the limit switches, have you checked with a multimeter what reading you're getting at the BOB?

I've just had a quick look at a photo of the bob, and with the switched not actuated, the voltage between the two connectors should be near 0V.

I get 5 volts at the break out board. Have virtually tried every combination now. Even just doing the one z axis switch it still works intermittently or not at all. Just so I'm doing it right. I put one wire in first z limit terminal, run it to switch, run second wire back to second terminal from switch. Now there is a closed circuit. When switch is hit circuit opens. Have tested all with multimeter and all works as it should. Not sure where to go from here. Have tried 'invert' in linux setup also.

Heres a vid, notice only two axis running, third done by hand
