I recently received a Ft-5 printer that has been out of commission for years, so I purchased a replacement mks gen v1.4 for it. The motors, fans, and extruder are all working however the heatbed is not turning on when on pronterface I give it the set bed temp command and it sets the target temp on the graph. On the board itself, the led for the heatbed (if I’m not mistaken d8) is not lighting up like the led d9 does when I set the temp for the extruder. Is there some config I should have done when setting up the printer for bed heating to work? I’ve done continuity testing and it passed which is what leads me to believe it’s firmware issue.
