With the latest Marlin build my PIN 3 seems to be blocked. On GEN7 this PIN is used for the heatedbed heater. After sending "M140 S90" the target Temp is correctly reported back from Marlin but the heatbed doesn't get switched on. Flipping the nozzle-heater pin to "3" results in the same behavior for the nozzle. A hardware failure on my GEN7 can be elimanted cause after switching back to an earlier build the heatbed works like a charm.
I've "diffed" through the files and read about the last few commits but couldn't figure out whats causing the problem. Can any GEN7 user confirm this behavior?!
