I'm not sure when these should turn on, but I would expect that at least lighting up the work space would be intended. We initially thought that they might be wired incorrectly, but from the printer command list we found the "pwm pin value" command. With "pwm 8 255" we can at least light it up. With "pwm 7 255" and "pwm 9 255" we're turning on the cooling fans. !save has no influence in the fan's on init. Any comments or suggestions?
