did that first thing- nothing. contacted Leadshine, they sent this diagram, which I'm trying to decipher...
Looking at the right side, I believe they're instructing me to jumper 12vdc to Opto1, then wire 12vdc, opto1, and input 1 to the touch plate, and ground to the the router/bit.
I have no idea what's going on in the left diagram.
this is the note from Leadshine-
Hi Marty,
According to your description, the setting is correct in mach3 system that input3 is configured to pin12 and input4 is configured to pin13 of DB25 connector.
However, there would be something wrong with your touch plate connection or signal transmission, usually low level effective for input signal and you can also reverse its level in mach3 system.
Here i show you a simple drawing in attachment for your reference, please check and correct.
Thank you for supporting Leadshine products!
Best regards.
Tomorrow, I'll try it per the right side of the diagram- if I'm screwing up, please steer me in the right direction!
thanks for the input.
