So my printer seems to work really well now. Getting pretty good results and very happy with most of the results.
However I seem to want to print things that dont have a nice flat base to print from and have big overhangs etc. I have got round this a couple of times by splitting the model and printing two halves with location bobbles to re-join, but this is a bit rubbish, so I would like to try the PVA support material idea.
So I need to make a dual head extruder presumably (I am actually pretty happy with this part, I assume that the best bet is to get two hot ends as close together as possible and feed the filaments in at slight angles to keep the effective build area large)
but then I also presumably need electronics that can handle another extruder motor, heater, and thermistor and control software that can use the two heads. And a slicing program that will fill in the support material...
Is there a basic guide to this kind of stuff anywhere? Any good resources I should check out?
Thanks
George
