Back in 2014 I built a Prusa Mendel with a Lulzbot Budaschnozzle 1.2 hot end. It has sat in my basement unused for 3 years or so. I was thinking about getting a new printer. In the mean time I decided to see if I could get the old one going and it worked! I still want to get a new printer but the new printer will use 1.75mm filament and my Prusa uses 3mm. Is it difficult to change to 1.75mm (so I can keep an inventory of only 1.75mm filament to use with both printers)? I know I would need a new PTFE tube, possibly a new nozzle and do a firmware upgrade. It appears that Lulzbot may not carry the upgrade parts for the Budaschnozzle I need.
