Gavitka Hypercube Evolution Alterations

cults3d

Update: I have switched back to the original Hypercube Evolution design. I could not get the part cooling fan ducts to work properly. One duct would blow air at the bed while the other blows air directly onto the extruder cooling it off causing terrible layer adhesion. Maybe a rear mounted 5010 fan like others would work better because the Hemera hotend is off center. When I get more time I will dabble in it again but we'll see. Here are a couple alterations I've made to Gavitka's Hypercude Evolution design. I added a BLTouch mount to the front instead of the side. I doesn't look as sharp as Gavitka's design but with the Hemera being so large it give back some X travel, still lose about 10mm, but from the other side needing clearance from the motor mount and Z rod brackets. You can still using a P.I.N.D.A. probe, or an after market P.I.N.D.A. probe like the LJ8A3-2-Z since it's the same size diameter. You will again loose X travel distance and you'll need to set your travel limits in Marlin to be sure the gantry doesn't crash. Here's the offsets for both For the probe: x 49 y 48 #define NOZZLE_TO_PROBE_OFFSET { 49, 48, 0 } For the BLTouch front mount: x 31.6 y -42.4 #define NOZZLE_TO_PROBE_OFFSET { 31.6, -42.4, -0.0 } Update; For the Y carriage I have added the locations to the inside of the parts. Example: "LT" is the Left Top, "Lb" is the Left Bottom and "LC" is for the Left End Cap. I made the holes for the 10mm linear rails slighter larger. Also, there is now more clearance for the belts and inner bearing. For the X carriage I have made the fit tighter around the Hemera and given the extruder wires a path underneath/along the back side. This helps keeps the wires off the bed. *Note the wires might fit snug, I used a dull small flat-heat screwdriver to tuck them in the groove. A Popsicle stick works well too. There is also a bolt hole on the top for the 2 x carriage halves. The original design only held them together with one bolt on the bottom. I made them smaller as well so I only needed an M3 x 25. The belt clamps have 2 purposes. They help clamp the belts down and act as an extra buffer for sensorless homing, such as with the TMC2130 or TMC2209 stepper drivers. The BLTouch mount is set to the ANTCLABS recommended 8.5mm above nozzle height and it works well for homing Z and auto bed leveling.
