Extruder Block (DIY PrintRite - Replicator)

thingiverse

This is my version of the extruder block for DIY Printrite (should also work on replicators). -12mm capacitive or inductive sensor mount (no loss of print volume) -fan duct with led slot -adjustable belt tensioner -bowden or direct drive mount -compatible with my cable chain setup Print Settings Printer: DIY PrintRite Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 20 to 80% Notes: Only the E3Dv6 Mount needs a few supports. Some parts can be printed in PLA, but you'd better print them in a high temp resistant filament (ABS or PET...). The carriage won't support PLA, it will bend with bed heat. There are many nuts captured in 2 parts Edit 05/2017 now STLs without captive nuts(not tested) : -7 nuts in the Fan Adapter -4 nuts in the E3Dv6 Mount Part list: a bunch of hex socket M3 screws: -2x M3x30mm -4x M3x25mm -5x M3x10mm -4x M3x(your fan width+5mm) 13-15 nyloc M3 nuts. 4 linears bearings LM8UU. E3Dv6 hot end or clone. (I'm using a clone) A 40mm fan. A 12mm capacitive or inductive sensor. 2 5050 leds and a half kilo resistor (optionnal) Screws needed for the feeder. Post-Printing Post-Printing Direct Drive Part has a support part to remove. The sensor holder of the E3Dv6 Mount has a small part to brake/cut. (between the holder and the wall) To save a supported print, the Bowden Part has a thin horizontal wall to brake/cut for the screws. You'll find the lever parts for the feeder here. Mounting -First you might stick 2 nuts with a drop of glue : one on the E3Dv6 Mount (for the sensor holder) and one on the Carriage (for the belt tensioner). -Plug the E3D hot end in the E3Dv6 Mount with the heat sink fan. -Set the Direct Drive Part and the extruder stepper motor or the Bowden Part (2x M3x30mm). -Set one end of the belt into the Carriage (the one on the hot end side). -If you go for the direct drive setup, plug the Stepper Support on the Carriage. -Screw the E3Dv6 Mount to the Carriage (4x M3x10mm). -Plug the Cariage on 2 bearings of one rod (the one that will be hide by the fan duct). -Set the Leds into the Fan Duct slot. (more infos here) -Time to fix the Fan Duct under the Carriage. Use 3x M3x25mm screws and the Fan Adapter. Don't forget the belt between the Carriage and the Fan Duct. -Plug the Carriage on the bearings of the second rod. -Screw the filament cooling fan with 4 screws (screws will depends on your fan width). -Tension your belt with the last Belt Tensionner and a M3x25mm screw. -Finaly set the sensor with a M3x10mm screw and connect all things. Custom Section Firmware, Softs and Connections You will find a full Ramps1.4 settings on this topic. Edit 05/2017 I added thin horizontal walls (0.2mm) over the captive nuts of the Fan adapter and the E3Dv6 mount to improve printability. I also made a version of this 2 parts (noCaptiveNuts) with open slots for the nuts. I didn't test it, I can't guarantee the solidity and durability. Printability should be OK. The noCaptiveNuts_Fan-Adapter part got 2 less nuts to fix the fan...hope that it will still works fine...let me know.
