Hypercube Evolution/ Hevo BMG direct extruder carriage by BerronGears

Last crawled date: 3 years, 2 months ago

X-carriage for Hypercube Evolution with mount for direct BMG extruder with E3D-V6 hotend.
I wanted my Hypercube to have direct drive. I decided to design it myself as I wanted it to be one part (extruder mount), have a cablechain mount. I also wanted to hide as many wires as possible.
Carriage with cablechain mount is inspired by this design and you can find proper frame mount in there:https://www.thingiverse.com/thing:2793108
Belt tensioning system is the same as original(I know I should put the whole design as remix to it, but for unknown reason I was unable to select it):https://www.thingiverse.com/thing:2254103
Features:
-David Crocker's IR sensor mount
-BL-Touch mount
-internal cable routing for fans
Part list:
-4020 blower fan
-3010 fan
-E3D-V6 hotend assembly
-BMG extruder
-optical enstop(
-3x40mm M3 bolt (for mounting extruder with motor/maximum head high is 3mm)
-5x20mm M3 bolt (for connecting carriage and extuder mount)
-2x15mm M3 bolt (for 30mm fan)
-1x30mm and 1x20mm M3 bolt (for blower fan)
-6x10mm for belt clamps(BL-Touch) or 4x10mm & 2x15mm M3 bolts(IR sensor)
-6x M3-5mm brass inserts
-1x M3 nut
-2x10mm bolt for optical endstop
-optionally 2x10mm M3 bolt and 2x M3 nut for cable chain connection
-2x bolts for connecting BL-touch or IR sensor
assembly notes
-You have to put hotends assembly through the hole at the bottom and extruder from the top. There is no way to firstly assemble extruder with heatsink and then screw heatblock into it. I know it's not perfect solution, but I was able to do it in one minute (remember about the bowden inside heatsing).
-whole thing is not compatibile with original Hypercube carriage (you can use original belt clamps for IR sensor version)
-the only bolt using nut is the one in the centre connecting carriage and extruder mount (and cable chain ones), rest of them should be screwed directly into plastic and sit tightly.
Other four bolts should sit tightly only inside the carriage and fit into the extruder mount (like in originall hypercube assembly). If the holes in mount are to small you can use a 3mm drill, but don't make the holes too big, unless you want to loss acuraccy.
It's my first working carriage/extruder design. I know it is not perfect but works fine for me. I am opened to any suggestions.
