Gavitka Hypercube Evolution Alterations by MatthewB4

Last crawled date: 3 years, 2 months ago

These are a couple alterations I've made to Gavitka's Hypercude Evolution design. The BLTouch mount didn't have any clearance between the mount screw head and the BLTouch. Also, with only 1 screw holding it in place it would swivel around. I've added a protrude on the wedge to prevent it from swiveling and a groove to the BLTouch mount so the screw head is inset further away from the BLTouch.
I found that I lost about 35mm of X axis using this setup so I switch to a smaller probe. I'm using an after market P.I.N.D.A. probe but the LJ8A3-2-Z will also work since it's the same size diameter.
Here's the offsets for both
For the probe:
x 49
y 48
define NOZZLE_TO_PROBE_OFFSET { 49, 48, 0 }
For the BLTouch side mount:
x 56
y -15
define NOZZLE_TO_PROBE_OFFSET { 56, -15, 0 }
I plan to add more changes to this make. I want to move the probe mount to the back of the carriage so I gain back almost all of my 300 X 300mm print area. While I'm at that I want to add some hooks and grooves to better route the wires.
Also, the part cooling duct might need to be redone. The left side is almost right up to the nozzle and heater block while the right side is quite a bit away. I don't see this being very efficient. But this is something I lack when it comes to designing.
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.
I didn't like having the BLTouch or PINDA probe on the side because it causes a 25mm to 35mm loss of print space so I made a BLTouch mount to go into the front. This gives me full probing of heat bed 300 x 300 and nearly full printable space on my heat bed. My build area is now 290 X 295Y. It doesn't look nearly as sleek in the front though, especially with all those wires. I'm still working on fine tuning the parts and how to best manage the wires. But for now I have to work on getting my slicer settings tuned.
*The offsets for the BLTouch mounted to the front are
define NOZZLE_TO_PROBE_OFFSET { 31.6, -42.4, -0.0 }
I didn't make the BLTouch mount with an adjustable height but it is set to the height recommended 8.5mm above nozzle height by ANTCLABS and it works fine for homing Z and auto bed leveling.
