Hello all,
I've got a quick question related to Marlin bootup. I've been working on a custom version of Marlin, and ran into a weird error on the hardware side. Currently, when I power my board, the pins used to drive the hot end and bed stay on for a brief period, raising the temps of both. Once the firmware boots, the pins turn off and the firmware functions normally. I don't really feel comfortable with uncontrolled heating, even if it's brief. How do I configure Marlin v2 to make sure the hot end and bed aren't being driven right when the board turns on? I'm fairly sure this isn't a bootloader issue, as I had ran rep rap on this board before Marlin without this issue, and the problem doesn't occur if no program is loaded onto the board.
Thanks in advance for the help!
