Good morning,
I'm a new member of this forum and this is my first CNC build. I have assembled a TopDirect CNC Router from Amazon, everything works fine after about 8 hours of building.
I have mounted Micro Limit Switches, Left and right on the X Axis, Front and back on the Y Axis and only 1 at the top of the Z Axis.
The Limit Switches have Normally Open and Normally Closed pins on the bottom and a Common pin on the side.
I have found many and varied diagrams for wiring them together in series, but my problem is that I have 3 pins to input to on the X Y and Z Limit pins on my Chinese Woodpecker (?) board.
The X-Limit, Y-Limit Z-Limit and Serov inputs (which I assume should read Servo?) all have + - and S marked on them.
Every other diagram for wiring limit switches to a Chinese Woodpecker Style board suggest only a + and - connection.
Can anyone please offer advice on how I should wire/connect my limit switches?
There is a picture of the board attached.
Many thanks,
Adam
