J-Head Printrbrot Simple V4 with Auto Level Sensor

thingiverse

Jhead bowden or possible direct drive mount for Printrbot simple. Also designed another piece that adds spot for inductive sensor. You do need the fan assembly also. The j-head requires cooling across its fins. Also working on mount that for extended y axis also. Parts needed 2 M3 30mm Screws 2 M3 20mm Screws 4 M3 10mm Screws 2 1/8" Pushlock fittings PTFE Tubing 1 40mm fan 6/10/14 Completed all the pieces and redesign the fan assembly twice. All is running very well on machine and have now stepped up my printing to 60mm/sec with no loss in quality. Gonna do more testing to see how much faster I can go before equality suffers. Will still like feedback good or bad to let me know how its working for others. 6/7/14 Complete redesign of parts now. Jhead is now about 4mm lower which will help with bed height on the simple. Two piece design with fan cooling for jhead fins and filament cooling from same fan. Also one piece mount design that bolts directly in to late 2013 and earlier printrbots. I will need someone to confirm if it works on later models. Will try and get printed soon and post pics of piece and piece on machine. If you build it first please give feedback to let me know what you think. Just added a spot for inductive sensor also. Hole is big enough for any sensor no bigger than 11mm round. I built it particularly for my sensor LJ12A3-4-Z/AX. Sensor also can not be any shorter than 50mm thread to tip.
