The extruder board has a space between the osc and the quad head for a cap but I don't know which one it's supposed to be. C12 and 13 seem to be for the osc and r2 is the only other marking next to it. Should I be to assume that it's actually C12 and C13 refers to both caps on the osc? It just appears there on the solder webpage.
also, could this be what's stopping me from programming the chip? I have the right chip, I have the bootloader on there etc.
thanks
