Change from a Servo to a Induction coil. #10

Hi there, I have decided to change from a Servo to a Relay induction coil trough a driver i made with a transistor that just gets a signal and allows the current to pass to the coil. My issue now is that i am not very good with programming and i am having trouble changing the grbl code to make the PenZup and PenZdown activate the inductor.. Is the a way i can change the code to use a different pin that is not PWM so i can just send a High and Low signal to the coil to be activated when needed? Thanks

Use the standard GRBL 1.1 firmware. set $30=1. Use LaserGRBL software. Connect your solenoid relay to the Spidle enable pin (or Z_Limit if you're using an old shield). instead of firing a laser,, you will activate your solenoid.

I'm building a solenoid plotter too.
