anyone have any experience with losing a varspd port on the Apex controller? I can't get an output out of one of the built in ports, not the VDM. I can have it on 100% and still not have 10V coming out. Are these ports just that sensitive? Best I can tell I tried running a pump below 20% overnight and the pump didn't like it. Could that cause this port to fail?
