hello all, my name is Moe first time controller builder here, so please forgive my lack of knowledge. im teaching myself.

i have the UCSB and the uc100.

im having a hard time when it comes to the inputs.

i cant seem to figure out the limit switches, e-stop, and prob

outputs i got. flood and mist all working.. but these darn inputs got me.

limit switches are NC and there are 3 of them x,y,z. the prob for now is just for tool height. so it just has 2 wires.

if i could see examples or diagrams. i feel i could figure it out.

thanks for any help giving. and sorry for what im sure has been asked a lot. but i could not find what i was looking for when i search this forum.

pics are for the probe wiring

probe 1 pin:13 port 1 active low is checked

does the wiring look right for the NC limit switches I10 - I12

x axis
limit + pin 10 port 1 active low checked
limit - pin 10 port 1

y axis
limit + pin 11 port 1 active low checked
limit - pin 11 port 1

z axis
limit + pin 12 port 1 active low checked
limit - pin 12 port 1

this is what i have right now i get 24v at SW and at the ucsb. but i have no lights on the Input LED's

thanks for all the help and input on letting me know what im doing wrong.

Trying to remember how I did mine, its like the diagram in the PDF. I believe all the (-) on the Pins used went to (-) on the PS and the (+) came from the PS and through the switches and back to the (+) of the Pins used input. Mine had all the Limits in Series to one Input except for A drive motor same for Home all except for A which makes the Y and A motors sync together. A stepper motor is Slave to Y axis motor.

I don't understand your showing connections to a ribbon or other type of connector, mine works as I have described.
