I have heard a few people mention Automation Direct for prox switches, not sure if they are reasonable or not as I have only ever bought PLC's from them.

Their "mini" switches are around $14 which is quite reasonable, but they are large in size at about 1" x 2".  I have some of these here but can't use them because of the size.

Hi,

Just a little update on the proximity switch and emergency stop saga.

I spoke to Arturo at cnc4pc this morning and it turned out he was really helpful.  I thought I would share this information in case it would help someone else here on the forum.

The C10 - Bidirectional breakout board Rev. 10 has a jumper that will allow you to either pull up or pull down all the inputs on the board.  When I moved that jumper it allowed all the N/O inputs from my proximity switches to work correctly but then when I hooked up the E/Stop input to input 15 and also the 5 volt input for that input the E/Stop would not work.  Arthuro told me to remove the wire from the 5 volt input and attach it to one of the available ground terminals.  That fixed it.  Now I can operate all the N/O proxiimity switches and have my E/Stop work correctly too.

Thanks again to you guys for offering suggestions and thanks to Arthuro for supplying a solution for a product that he sells and supports.

Life is good.  Now on to getting the soft limits and homing working. :)
