Ok, my prints are going good, with the exception of a few here and there, but im having problems with supports and rafts.
How would I go about adding a second extruder to my prusa for only supports and rafs (PVA)?
This is my printer, ive upgraded a few things like ive added printed platforms to the z axis threaded rods to stop z wobble. changed to a ramps instead of melzi and added belt tensioners.
The extruder on there is currently MK8 and i've spent a lot of money on this machine so far and want to do this as cheap as possible.
I have never built an extruder before as this one came pre assembled (i added it to the supplied mount and put the fan on, ive also done the calibrations)
I live in the UK so would prefer the item came from the UK as packages from china take forever.
could anyone provide me with a list of parts or an idea of what kind of extruder id need?
Would it have to be the same type of extruder or could i get away with a cheap one?
