Smoothieboard

[PcS]

Thank you for your service !!! Words are not enough !!!

Great attitude Dennis.....you'll live to be a hundred, thinking like that!

Thank you guys for give me the chance to give my service I'm a very positive person and really there is no reason why anyone living in this day an age shouldn't be hell look at this awesome stuff we all get to play with and share our thoughts on and help one another!! how bad to the ass is that? I have spoke to Rick at MG and you couldn't ask for a better person to deal with and know that when you need help with something on your printer or just need to ask about something his crew is there and ready to tackle the job/task at hand and i love to support our small businesses as this is such an important part of what we lost in our country. I think we would all agree there!

As for myself i have lots of hobbies and lots of cool things I get the chance to share with and teach not only my boys but a few other guys i have "taken under my wing" but with forums like this we all get to learn from one another and even tho i may know a lot about a lot of things i don't know everything and learning is something love to do!

Alright well i don't want to move off topic to far from this really awesome Smoothieboard that will be at my house on Monday!! But please understand that this whole forum stuff is new to me as I'm very much a stay to my self kinda guy almost a hermit but not there yet lol I do have to fly around for business meetings and i donate percentage of money I earn to children's Hospitals all over the U.S to help family's that are struggling with bills,travel an so on as i lost my mother to T-cell Leukemia which is found in kids more than adults and what better feeling to give help to those who truly need it right!? anyway enough with that you all get the hint lol i keep myself busy cuz I'm still human and i have problems i have to deal with also just like everyone else

Now the fun part as if you guys haven't put the pieces together yet I'm building a huge as in 4' x 4' x 4' 3D printer that will also have a laser (100w co2 laser is what I'm aiming for now but could change) now the bed will not move instead it will be gantry style where the Z axis ran by two NEMA 23 servo's will move the X axis with two ball screws the X and Y will use GT2 belts the total size of this will be 5' x 5' x 5' and I would like to keep it all contained with in this 5 foot square..

As for the bed I would like to go with MIC6 (cast) alum 1/8" plate and of course heat it but i am running into trouble with the heating part. I contacted the sites i was given and the one that sells the silicone heater doesn't seem to wanna work with me at all. As a matter of fact i emailed them telling what i needed and the replay was that they don't make anything that size and the biggest they go is 12" wide by 48" long well what i really need is something that 46" x 46" so i have an inch around the edge for mounting and leveling and I'm not sure if i should go with a glass plate on top like out M2's or just print onto the alum and its not cheap stuff so maybe the borosilicate glass top would be a good idea.. Don't be afraid to chime in with ideas cuz I'm a fly by the seat of my paints kinda guy..

right now I'm waiting for my linear rails to get here all are 1500mm and I ordered 10 of them with pillow block bearings and regular bearings (round) and the ball screws are also 1500mm all of these i can machine the ends to my needs.. I also ordered a few of each GT2 pulley's 16T,20T,36T,40T I want to test them and see what will suit my needs the best, the servo's are 350oz in servos..

so please by all means feedback is def welcome as i don't get to look things up on the interweb as much as i would like to..

Ps. right now until all my stuff gets here for this build I'm building an enclosure for the M2 which is in a room in my basement that has no windows so I ran 2 1/2 inch conduit to the outside with a 120v 3" (really the fan its self is 2 1/2") to pull fumes from the room its self and not just the enclosure but it has 2 140mm computer fans with plates i printed that i can slide open little by little to control air flow and i also have a computer fan controller so i can control the speed of them also.. The enclosure is made from 1/4" x 24" x 24" x 24" plexiglass...

told ya I'm a busy body! lol

Hope you're designing an enclosure for your retina searing box. Check out Ed's strenuous warnings in this old thread: https://groups.google.com/forum/#!topic ... h9IawuBWME

Dennis,

Sorry the guys at Omega had no imagination. Did you check out Watlow as well? I did a bit more searching, and these guys will do custom work: http://www.hiheat.com/products/silicone-rubber-heaters

Edit: these guys, too: http://www.keenovo.com/design/flexible-heaters.html

Not sure what that would run you -- probably pretty expensive. But if you call them, at least you'll know.

As for the addition to the house, once you get Big Bertha running, you'll be able to print the structural elements for that addition!

jsc yes it will have an inclosure made from one way mirrored 3/8" acrylic.. The main reason that it's going to be a foot bigger in each direction is so that everything can be inside the frame and a compartment in the back side will store all the electronics and radiater for the laser.. I have worked with co2 lasers in the past and since they have an invisible light I will add a red dot laser to know where it's at for aiming and it will show up any kind of disbursement of the laser from the mirrors or anything else but they are very dangerous and not to be taken lightly (no pun intended) but Ed is very right they are no joke..

Dale I have not but I will now! Thanks a bunch!! Yea I was planing on the bed heater to be up there in price lol but it's what we run into when building something completely custom..

Lol my wife asked the other day is we will be able to just print out the pieces for the addition and glue them together

It will be awesome to see a huge 3D printer like this.. I was going to make it a router table also but I think il save that for another project as all the dust won't be good for the rest of the machine..

I know Tim is into electronics and such and I was wondering if anyone has used or owns a Rigol oscilloscope? They seem to have good reviews and mich fun to have one to play with.

My Smoothieboard will be here tomorrow and I did order the 1A voltage regulator from Digital-Key as I needed some connectors and pins also. I think I may get a another Smoothieboard and build a Delta printer (normal sized lol) but you can never have to many printers right?? Lol I already have a bunch of filament well a ok I have a ton of filament of al kinds and I have a foodSaver vacuum sealer and I got the extra large bags that are made for turkey and large dishes an ty work great for the filament even tho I keep that room about 45 % humidity..

Here is one for you. Took these at the 3d print show. I know jetguy has a printer he built thats 4x4x4. I saw that one at makerfaire

Sorry for the img size. Posted from my phone

I don't own a Rigol, but they are well regarded. If you don't need four channels, there is an easy firmware hack to upgrade the 50 MHz version to 100 MHz.

Delta printers are interesting to watch, and I considered building/buying one when I was printer shopping, but after doing some research decided they were too finicky to set up. Besides the difficulty of calibrating the non-cartesian mechanics, almost all of them use a Bowden drive to reduce moving weight, which removes the possibility of printing flexible filaments. People have done direct drive delta conversions, but then you lose some of the speed advantage of the delta setup. (I'm not convinced there IS a speed advantage; people [e.g., Ed Nisley] print on the M2 at ludicrous speeds already, and you soon get into issues being able to melt plastic fast enough.) I think the main draw to a delta is that it looks cool.

In a similar note, I would suggest you design your giant printer for high-speed printing, with a large nozzle. No point in having a huge build volume if it takes a week to fill it.

[Dale Reed]

If you put the build platform on a wide belt, you could take it off and use the speed control and have the thing double as a treadmill. Might as well keep the cardio going when you're not printing... Now, how fast do I walk in mm/min?
