Hyper cube build
« on: November 09, 2016, 05:52:18 PM »
                                                     
http://www.thingiverse.com/thing:1752766 after watching T2C build log a few times and having saved £60 for another project and having an prusa i2 which  I could cannibalise for parts along with T2C excellent video build guide The cube became to tempting to pass over.
       
    there's 13 parts to watch

build it time:
   I ordered the  beams £34 and a few of the other parts of ebay nuts,bolt, bearing and belts brought the total spend close to £55 " T2C provides an extensive BOM List on TGV.

   The Hypercube turned out to be a fast build take about half a day if you have the parts in front of you, a Philips and a Allen key for tools.  The way its designed it practically levels itself.

first step build the box frame

being the cheap ass I am opted to print the corners saved a tenner, while the  frame going together added the Y axis bars along with the lm8uu bearing. " more on that later".

   Next I built the Z axis and perhaps the most time spent here getting it right and  tweaking the Z lead screw for the minimum force required to raise and lower the bed  by hand. I adapted the Z carriage to be able to get more bolts and nut  on the Z beams http://www.thingiverse.com/thing:1848728

    The lead screw are a little shorter than what the design ask for they were meant for the prusa i2 at 250mm.
while I was tweaking I had the idea of adding the top plate of a mendel max Y frame I had around, had to drill a four holes in the plate to fit the beams spacing. and awaiting an aluminium mk2 heatbed  " which gets attached later on in the build

happy that the Z axis would run smooth the next step was to mount the X,Y
 motor mounts and its installing these you get a sense at just how simple and elegant a design the cube is, if the top beams are level with the upright corners than all the pieces are pushed up against right angle bracket the Y Bars become parallel to each other on either side of the frame



 now for the belts fiddly at times but straight forward enough left side though the top section of the xy joiner and the right  on though the lower section

next it was the xy joiners here depending on which beams you opted for, here I already added the bearing and bars,
waiting for the  623zz flange bearing  when the pic was taken also adapted  these parts to hold two bearing  http://www.thingiverse.com/thing:1874781 I had to tweak the bolts to prevent the  bearing binding  with each other, the idea here is to have these joiners glide across the bars with just a flick,


  Once the joiners are installed it's time to add the X carriage, you cant see it in the pics but I used 4 lm8uu bearing and again time taken to adjust the  bolts on the bearing holders  so the whole carriage glides across, and at this point I had something that resembled a coreXY printer. 

 
 next was to install the belts a little fiddly  but straight forward left side  passes through the upper section of the  joiners and left through the lower section  takes a little tweaking of the pulleys  on the motor and tension on the belts to get right , but I had something I could power up and test.



   The tronics is the bastille of 8 bit 3d printing!. Ramps 1.4 with A4988 mounted in the base and using the groves in the beams as conduits for cabling.



    I opted for the endstop modules rather than just a switch "going cheap on ebay £3 for five"  1 mtr cable more than enough for where ever I put the RAMPS. Am still undecided where the final resting place for the RAMPS will be.

 Extruder and hotend setup as a titan extruder with a v6 hotend I made a mount http://www.thingiverse.com/thing:1873648 does an ok job, but along with the LCD its the only other piece  that outside the frame,


 I used T2C mount but not needing the fan blower I thought I pop the wires through the void, such a bad idea although you cant see it in the video

the cabling caused the hotend mount and x carriage  to raise ever so slightly  but the effects on printing was bloody awful "looked as if a rat was eating at the walls! and the main reason I added a second bearing to the joiners thinking it was the loose bearing on the bar causing the wobble, then realised  its the cabling being passed through the void of the mount"
    So not needing the the void in the HE mount I modified a shorter version  http://www.thingiverse.com/thing:1876861  and using the v6 adjustable shroud world order was restored!.

the cube is finished  and modified for a complete M8 smooth bars gantry


Let the test begin!!
  all models where sliced in cura, with varies changes in setting

the owl:
speed         : 20mm/s, 150mm/s   'non print movement
layer height: .24
infill           : 10%
retraction   : 4.5mm 40 mm/s
shell thickness:0.8
 spun a nut of the left XY joiner " use those nylon lock nuts"


voyager:
speed         : 40mm/s, 80mm/s   'non print movement
layer height: .24
infill           : 5%
retraction   : 4.5mm 40 mm/s
shell thickness:0.8


hitman:
voyager:
speed         : 30mm/s, 80mm/s   'non print movement
layer height: .22
infill           : 5%
retraction   : 4.5mm 40 mm/s
shell thickness:1.2

hitman actual print speed varies throughout the model, 30mm  print cooling fans cant keep up!.

Hey Jinx,

I am just about to embark on this build, but looking to upsize the print bed to 300mm x 300mm and build height to 500mm.  I figure, if I'm going to do it, might as well make it bigger than my current (rubbish) printer!! :D

I too have watched the whole series on the build, however, still haven't found the answer to my conundrum, so I'll ask, lol.

What are the dimensions outside the print area of this?  So from base to bed, then nozzle to top and each side around the bed?

Cheers
Rich

Welcome to RR

  scaling the orignal aint gonna be straight forward at those sizes start with the Zaxis  500 mm beams  you loose an 120 mm with a v6 hotend to the xy gantry at the bottom close to 80 mm with the stepper and coupling, so its around 300 mm printable  area on the Z

 the X axis roughly 75 mm each side of the bed from the outside of the corner beams so roughly 450 make it 480 " you may add a bigger cooling system or something". 

Y axis again around 70 mm from and back 480mm.

those are a rough guess, I be concerned if the bed stay level you be looking at 380 mm beams for the bed to sit on , held in place on one side!. then I consider using 10 even 12 mm steel bars Z rather than 8mm " they a few mods on thingiverse for 10 mm so it doable.  thinking you need extra support beams to ensure the frame rigid like i did with expanse http://www.robotrebels.org/index.php?topic=661.0

 you familiar with any scad  like sketchup make ?  be a good idea to model this and

Cheers for the welcome... and thank you for the reply :D

I was potentially thinking rather than using a cantilevered bed, instead adding lead screws and Z beams on either side, mounted outside the frame so as not to impede the XY movement belts and gubbins.  OK so it'll add a bit of width, but reduce on the depth, which is more important for the location I'm looking at.

Your measurements give me a lot to go by though in terms of framing up.  I'll have a play in Fusion 360 and see what it looks like in simplistic forms.  I can't use sketch up for the life of me lol.

Rollers?

I'm still getting used to some of the terminology  :o

aaah, right.

No rollers in the build.  I'm currently looking at two leads screws on direct driven with stepper, the other with closed loop GT2 on the other side of the bed, add in tensioning rollers and golden. :)

Once' I'm in a position to, I'll chuck up a build log :D
