Direct Drive - IR Sensor & Hot end Test Model
thingiverse
This is the Direct Drive for Bens BLV printer. I'm still working my way through printing parts, but here are the modded files thus far. The IR sensor will fit on the fan bracket and internally attach to the E3D V6 hot end or protective cooler. Ben has suggested incorporating a 20mm piece of PTF tubing to fill the gap between the drive and E3D V6 hotend. From the bracket to the tip of the E3D V6 Hot end is approximately 17.5mm gap on Bens Design. I'm considering eliminating that idea because personally, I don't like it because I don't intend to print PLA. All my printing will be in ABS so my direct drive system will be a "Full Metal Jacket" straight from the drive. (Hence the need for eliminating the gap). I'm currently trialing another bracket concept, but just thought I'd throw it up here to get feedback and suggestions on possible improvements? Please note, I am no engineer; this was all generated in Windows 3D Builder with the idea that it can be achievable. Test printing is still underway. Cheers Jace. Update 24/03/2019 The idea here was to design a compact system for "ABS Only" with no need for a PLA fan cooler. This object incorporated Bens MGN Rail mounting system, Dual Drive Extruder, eliminating GAP between Extruder & Hot end, E3 V6 Hotend, IR Z Probe. I have incorporated two IR Prob placement ideas in this model; both will need to be printed to determine the correct height setting is adequate. The model can be easily separated by choosing "Ungroup" in Windows 10 3D Builder.
