J-Head Printrbrot Simple V4 with Auto Level Sensor

thingiverse

The original text details the process of mounting a J-head Bowden or direct drive extruder on a Printrbot Simple, along with an additional piece that accommodates an inductive sensor. The fan assembly is necessary for optimal cooling of the J-head's fins. Furthermore, there's a work-in-progress design for extending the Y-axis. Parts needed include two M3 30mm screws, two M3 20mm screws, four M3 10mm screws, and two 1/8" pushlock fittings, as well as PTFE tubing and a 40mm fan. The author completed the pieces and redesigned the fan assembly twice to ensure smooth functioning on the machine. Printing speed has been increased to 60mm/sec without any compromise in quality, with further testing ongoing to determine the maximum speed before quality is affected. The author encourages feedback, both positive and negative, to help gauge how well the modifications are working for others. Recent redesigns have lowered the J-head by about 4mm to improve bed height on the Simple model, while a two-piece design ensures fan cooling for J-head fins and filament. A one-piece mount bolts directly into Printrbots from late 2013 and earlier models; confirmation is needed for compatibility with later versions. The updated design also includes a spot for an inductive sensor, compatible with any sensor no larger than 11mm round and at least 50mm thread to tip. Please provide feedback if you build it first.
