Hi there,
I would like to find out a bit more about home and limit switches. I just bought a 4-axis unipolar Xylotex board, which gives me access to the unused parallel port pins.
I am aware that a limit switch can just be a simple 'mechanical' switch that the table hits when it is at its limit, but I'm not sure what a home switch is like. Is it also just a 'mechanical' switch that is situated somewhere that the table hits when it reaches home?
What power supply does a limit/home switch use?
Finally, once the table has triggered the switch and stopped all motion, how does it start moving again if the switch is still triggered, or doesn't it?
Regards
Warren
