Try to control two solenoids at the same time

    Is there any way to control two solenoids by using BlackBox at the same time?

    I have two 24V solenoids that I would like to control simultaneously. I connected one of them to the cooling output of the Black Box and it works perfectly fine. However, I tried to connect the other solenoid by using the toolhead output and it didn't work out. Is there any other ways to connect the second solenoid so I can control them independently?
    Thank you in advance for advice.

    How are you turning on the toolhead output? You need to make sure you pass it an S value. ie. M3 S1000

    Careful! Wiring a load to a signal pin, can damage the signal pin!

    You'd need a drive circuit in between to convert the 5v logic signal to a drive voltage if you want to use the signal outputs.

    Alternatively, wire the second solenoid via the onboard relay (24v+ on PSU > relay pin 1 > relay pin 2 > solenoid+ > solenoid- > to GND on PSU)
    See docs:blackbox:jumper-relay [OpenBuilds Documentation]

    Thank you sharmstr
    It did turn on, but it gives me only 3V
    Is there a chance to get 24V output somehow?
