Hi All, I built a C-Beam a while back and have been having a great time with it. I am currently upgrading the electronics a bit right now. One upgrade is installing the SuperPID router speed controller. However, I am confused about the spindle enable/PWM pin and how it connects to the PID controller. The protoneer looks like it only has a spindle EN/PWM terminal (is it both??) where as the SuperPID has a RUN terminal and a PWM terminal. I cannot find any documentation or posts that explore this dilema, but I know some of you are using this combo. Thought someone could shed some light! Attached: Picture of what I am looking at.
