@Ziggy I got the solenoid hooked up and running on the FET circuit thanks to your guidance. I'm thinking I can use Pin 63 and already found the spot in the firmware for defining the pin (Stock is 11). Now I'm wondering if you had to modify the if_def NUM_SERVOS to be 1. Currently not able to find where this call out is defined. Found it in configuration.h. Looks like Servo enstop angle is set to 70 degrees? If I use a solenoid how does this affect that? Would I just set it to 180? I suppose I'd need to play with it. Did you have to add anything extra to the code? I assume the autolevel command will activate servo 1 on homing but I just don't know. In other thoughts I'm considering running a second servo motor to push out a brass bristle brush for cleaning ooze off the nozzle pre-printing.
