Solenoids not working in my first pincab build

[bart83]

Hi everyone this is my first post here so bare with me. I am currently building my pincab and i am at the point of installing the solenoids for feedback. I am using a kl25z board in combination with three green  mosfet boards and a separate 12v power supply. I tested the solenoids using my old arduino board and the mosfet boards so i know they work but when i wire everything to my kl25z nothing happens when i test them. I checked al my ground wires and i have 0 resistance.. Also al the solenoids are getting 12 v . Can anybody help me?. Also my Flipper button etc are working fine on the kl25z.

Hi guys a little update  . I checked al my connections using my Arduino board and everything works right away . I also checked the pins connected to my kl25z board there giving 3.3 v when i toggle the test button . The difference i can see is that when use the solenoids via the mosfet boards connected to my Arduino board the signal lights are way way brighter. ( Blue on picture) I m not understanding what is wrong .i could use some help.

But what function do these solenoids have? Do you use them for flippers? For slingshots? For bumpers? What do you use them for?

 

Are you using the PWM output ports on the KL25Z board? Those are basically the ones used for the DOF. Because the feedback is only activated after you perform a certain action. For example, you press the flipper button, the system sends the signal to VPX, which then sends it back to the DOF, triggering the action it needs to perform. In any case, if you use a PWM port on your KL25Z board (the ports are 1 through 10), you can generally activate the output test from there to verify that the solenoid is working.

 

I recommend always placing a diode on the solenoid and activating the flipper logic from the Pinscape software.
