@gixxerfast I just looked at the wiring diagram. It has this warning:
"Note: These outputs are protected by a flyback diode connected to V_OUT_LC_2. Do not mix loads connected to V_OUT_LC_2 with the jumper set to 12V and loads connected to V_FUSED on the same bank."
@Danal The code did the trick. Homing Z works like a breeze. Thanks.
@phaedrux I think the issue is the board is treating the bed heater like a nozzle heater. It is running tests with the fan on and fan off.
These codes:
M308 S0 P"temp1" Y"thermistor" T100000 B4138
M308 S0 P"temp0" Y"thermistor" T100000 B4138
They look identical. Perhaps there is a code for bed heaters.
@phaedrux Okay, I got things straightened out.
Thank you very much for the guidance.
@dc42 Okay, thanks for clarifying. I wasn't sure which firmware update to use.
@deckingman I have 2 fans, one for the hotend and one for part cooling. I have decided to just stick with my 24v fans, much simpler.

@gixxerfast Yes, there is another fan. I suppose I could move one of the fans to Out 4.
I have a 12-volt fan I want to use on Out 7. The 6HC board has 24 volts for Vin. Could I just connect one lead of the fan to the dedicated 12V pin and connect the other lead to ground on V_OUTC2 on Out 7? Wouldn't that make it controllable?
@phaedrux Okay, I got things straightened out.
Thank you very much for the guidance.
@phaedrux I am worried I got it all wrong. I have my heater connected here:
