I have a prusa i3 based 3d printer. I solved many problems and it runs good. the only problem is here, the D8 and D9 pins don't work! It means I have no heated bed and can't use D09 for cooling fan for the boards!
How can I fix that?
Also I have another question and don't like to creat another topic:
What do should I do after finishing the print? I tested a print and after printing extruder went to front corner. Can I shut down printer as soon as the print completed? or I must do some other things to prevent clogging the nozzle and etc! (sorry if this is a stupid question)
