What choice did hbo have?

Another round of updates. I have figured out the z axis belt tensioning. As you can see the bottom belt enters a printed block and then exits back out the bottom. I used another piece of belt along size to make sure it doesn't slip out. On the top, i have a screw and captive nut that pushes down on a block to pull the belt tight. I designed the part with some grooves so that it can't pop out. I didn't really have enough room for a belt along side the main belt where it exits (its there but only three teeth) so i zip-tied the belt together up top to stop it from slipping. It did not slip before i zip-tied it however. Over at it works These are the things the belt pushes against. I put a bolt on the top where the other bolt pushes into this piece so that the plastic doesn't get worn or give as much. The little slot was for an alternate idea that didn't go anywhere :D. I was going to slide in a small washer and have the main screw hit that and feed through the plastic piece. This way is simpler and works. Due to several factors i will need to redesign the hot end mount, as well as the x-rail. I am not happy with it ATM because it costs me too much y-space (3" almost) and i also need to be able to move it down about three inches. I think i will get another wider rail for the x axis and mount it in a more similar way to The Digital Dentists original design. In the end i may not go with the nimble because it creates about the same amount of problems as it solves. I bought it when i was committed to sticking with my Delta... was hoping i could repurpose it for the corexy but the drive cable will make an enclosure harder to design. Figuring out the z-axis was so far the hardest part of the printer. I eventually settled on this set up. I had an extra 8mm rod, so cut it to length and mounted it to the top of the printer as you see. The pulley slides on the rod without a bearing. Its not the best, but i think for my purpose it will be OK. If not they do have some 5mm id 8mm od bearings. I can then get some 5mm rod and mount it in a similar way, with the bearing in-between the rod and pulley. Im up for other ideas as well. I got the bed mount ready. The three black screws will be 50mm flat head screws that will be fed through the mic6 bed, with a spring, to allow me to level the bed. The aluminum blocks are tapped and there is a 6mm hole drilled through the extrusions to allow the screw to pass cleanly through without interference. I may need to beef this up, apparently the plate weighs 10 lbs! Coming along.

In cannuckistan it doesn't get above 80 degrees though, right?

Gtagrl, you could ship one of those to each of us! How long does Canada to us customs take? Should be fine for 3-4 days

Some minor updates I managed to mock up a cable carrier. I'm not sure if this one will have enough room to carry all the cables i need, but i bought multiple sizes so once i move into the wiring phase i'll make my decision. One of the biggest changes is that i decided to go with 3" L bracket for a more roomier feel. It doesn't cost me any y space, but it might cost me some x space. I'm not 100% sure this is the final design but for the moment i like it. It allows me to mount my extruder and hotend right to the aluminum. For the extruder i am planning to use the Zesty Nimble which is a worm gear extruder and then a cyclops/chimera for the hotend. Initially i wanted to with two v6's... but with the chimera i can still get most of the larger nozzle sizes... and i already have a water-cooled cyclops in my delta. I might add watercooling to this printer too if needed, but i think with the wide open space for airflow under the hotend mount and the big hunk of alumninum, i might not need it. I'm only going to 50c in the enclosure. I also changed how i routed the belts. I made basically a larger version of what was done on The Digital Dentist's corexy Z axis. It consists of a back plate, a center plate, and a front plate. The belts run through and are sandwiched together with six m3 screws. I have a peice of belt facing the opposite direction in each "tray" to help hold the belts. I'm not sure how this will work over time, but it seems like i got the belts a lot tighter using this method. In order to tighten the belts, i made the ends long so they fit all the way through the plates, then inserted a peice of belt along side the drive belt and pulled it though until everything was tight. Seems to work, but we will see how well everything handles being tugged on my motors soon. I also started work on the z-drive. Nothing too crazy here... looks like it will work. Finally decided to invest in a nice set of metric taps, which made tapping the mounting holes a lot easier.

3D printers let you create things you can't buy... I mainly use it to create custom enclosures for electronic components.... I've made custom vases as well... you can also use them to make lost-casting molds for aluminum parts. a lot of people use them to test fit components that in the end will be cnc cut from metal. Printing is cheap, machine time on a CNC is very expensive...

Minimouse is hot, but i got a system that was invented by a sweed that makes it impossible to die from auto asphyxiation... #hadtohaveit

Me too, massacre.

We should take bets on who is the next to die.

Just a small update today. I got the endstops for x and y going. I am using hall effect sensors. I am planning to print a small cover to cover the sensors The wiring routes underneath the extrusion so that you don't have to see it video

I have no idea what you are trying to say. I'm like six episodes in now, maybe more... the one where she doesn't get a note in the secret note thing from that guy. Still no reason to kill yourself here. She is still a cunt. I have a suspicion that people who were popular in school will like this show. It's stereoptypical rubbish. It assumes people who will kill themselves do it for easily identifiable reasons and if we were all just a little nicer no one would ever kill themselves. The show is silly. It is for us to judge whether a person is justified in killing themsevles. The statement "can't judge" is rediculous. Can judge and should judge. The show is pretentious garbage hurled out of the mind of some popular narcissist designed to elicit false emotion in equally egotistical teenagers under the pretense of empathy.

There are a lot of people with a lot better reasons to kill themselves than that spoiled cunt...

Better call Saul is as good or better than breaking bad

Well, honestly, we all thought it. We missed one before.... its customary to send the new members tit pics ain't it?

I watched the first two shows... so far not really impressed. I mean, there is no reason to feel sorry for the girl that killed herself. She sounds like a pretentious cunt that the world is better without.

13? shows left

^Worlds most complicated 2D printer

And she chootches! Or, at least moves. The sound you hear is from the stepper motors. Delightful, amirite? Im using a cheep-o control board in the back which is why the steppers are so loud. Will switch to a duetWifi once the build nears its completion.

Do you do tongue painting ?

i have about $300 in already, I probably will spend at least $1000 more. I am making it top of the line, spare no expense. They are using fans to cool down the stepper drivers on a RAMPS board. You don't really need the fan, i never had one of the stepper drivers fail.. Honestly though, i got some great prints out of a stock $300 printer.. It's just a matter of reliability.

Hi guys. LED's got me into Arduino, and Arduino got me into 3D printing. And now that I'm into 3D printing i've found a nice hobby. Anyway, i am working on a coreXY machine with an approximate build platform of 18" cubed. For those of you who don't know, that is a large format printer. The gold standard prussa i3 has a build platform of around 8" cubed, for comparison. My design is inspired and almost entirely coppied from The Digital Dentist's build over at RepRap.org. His printer is almost done, but I was so impressed with his build that I took at look at his pictures and I'm in the process of building an approximation. He has access to a milling machine, and I don't, so had to make some sacrifices to account for this, but over all its looking good. I was able to finish a version of the effector mount. I haven't fully decided on my hotend it yet so there is definitely going to be changes.... im thinking about either dual e3dV6 or i've already a cyclops i modified to have water cooling. I want to do a direct drive (no bowden) system, however. I have might have some Nimble extruders for the cyclops, and if they get here and work that might be OK. The only issue is now i have a big printer and i really need a .8 nozzle or larger to make practical use of it and they are only available with e3d v6. The motor mount didn't have enough "play" to get it to where i need to be in order to make the belts parallel, which is a requirement for coreXY printers, so i've got another one printing down that shifts the upper square over. derp. You can also see where i've added some mechanical stops to prevent the rail from sliding off the guides. Had that happen to me yesterday. Not again! (not a big deal, the rails have ball bearing retainers). Thanks to The Digital Dentist for the idea of the belt mount. Overall, the belts look parallel, which is good news. I'm waiting on the slowboat to get here for the larger pullys for the idler bearings... only option was to get them on aliexpress and wait forever. Well, unless you wanted to pay $15each for them. I've got an old RAMBO board hanging around so once i get the motor spacers reprinted i might fire it up and see how she chootches!. I've made some hole in the effector mount to attach a spare linear rail to so i can try the pencil thing DD did. I think that is a great way to check for backlash/optimum speeds, since you can easily see the ripple. Though, i expect with the hotend attached you might have to run a bit slower because of the added mass.

I make blueberry jam, but the blackberrys and raspberries I just eat fresh i am consisdering getting a bee hive stand... but I'm not really sure I have the time and start up costs are around $600

Yep, gardening is great.. i grow tomatoes, bell peppers, summer squash, green beans, and potatos... I also got blueberry, blackberry, and raspberry bushes... I use those as a perimeter around my yard.. I get a modest amount of blackberries and raspberries, but I get tons of blueberries. I still have a few pounds in my freezer from last year.

dish soap is sorta accurate, i could see the similarities. But, your not supposed to eat it like lettuce... your supposed to use it to brighten up otherwise muddy dishes.... it providers a sharpness to food.

seemed like some daytime soap opera so i ain't seen it yet.
