Ok, i am running the latest Repetier firmware, and i am aware that D9 is the normal place for a cooling fan. the latest Repetier has an online pre-configuration tool, which is nice, i guess, and of course, if has a preset for the RAMPS 1.4 board. However, when i activate the cooling fan via M106, no matter what speed, i get novoltage across the 12V terminals at D9. I am still pretty new (ok got my first, brand new RAMPS 1.4 yesterday) and i haven't figured everything out, such as:
* What pin should i make sure my pins.h and configuration.h specify for the cooling fan?
* Is there some resource for a complete pin labeling? i have seen the images on the wiki, but they just say D9, not a pin #
* My SD card reader (g3d lcd/sd) always seems to be inverted, when i pull it out, it reads aas installed, and when i put it in, it say no sd card.
