Topic: Home assembled SD2

After all the mods I did to my SD2, I realized I almost had enough parts lying around to build another printer. This got me thinking for a minute. Should I horde the parts like a hardware junkie, sell them, or make another unit? Well, all 3 sounded like fun, but I wanted to compare the differences between stock SD parts, and one modded from day one.

I decided to start with:
*Lawsy's carriages
*Pillow block
*McMaster-Carr rods
*E3D v5 w/Volcano 1.0mm nozzle
*Slightly modified MK5 extruder
*Supernight PSU
*DRV8825
*Active cooling on the board
*Vertical feeding for filament
*Acrylic enclosure with a snip of PTFE tubing to keep dog hair out of everything....if you have an Akita, you know my pain smile

As my first test, I can say I have zero issues with the infamous "circle problem" sweeping the community

This is going to be an ongoing project with other mods. Direct Y drive and 3mm Z rod, and fishing line are on my list for the future, but I really can't complain with what I've got going on now.

Thanks to the following:
wardjr for the Sanguinololu wink
elmoret for the frame which he had powder coated and installed radial bearings for the Y rod
n2ri for the platform
jagowilson for appropriately naming this printer "Spookidoodle"
Anyone's designs I used for the assembly
Everyone's contribution to the forum. 14 months ago, I would have found it impossible to do something like this. You all rock!

Re: Home assembled SD2

Nice work! Good performance from the Spookidoodle 1 so far. Any idea how much you spent, in total?

Lookin good sir. Id buy one. Now you need some lights. I recommend some white cold cathodes because they're cheap, but you'll need a couple because they aren't very bright.

Re: Home assembled SD2

I think I spent about $250-$300 since I chose to go through SD for some parts. That does not include the cost of stuff like the E3D or LM8UUs since I already had those lying around. All I really needed were the frame, platform, and a few motors and belts.
Come to think of it, I think I spent mostly on screws wink

I've actually been debating on blacklight LED strip since I think it would compliment the whole theme. But it isn't something I'm in a rush to do. I have flashlights tongue

Re: Home assembled SD2

I am not surprised at all those socket cap M3s can be some serious fairy tales to local hardware stores. especially when you get into the 30mm or 50mm sizes you need!

Re: Home assembled SD2

looks like power supply/motherboard is inside inclosure? thats not gonna cool well if so. maybe swap it with filament spools and add a low speed exhaust fan with charcoal filter on top. otherwise looks perfect

Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs

I need everything to be fully enclosed since I have a toddler running around who likes to get into everything. I have been running my other printer with the exact same enclosure (aside from a few vents) with no noticeable issues with overheating electronics. The PSU actually has a built in fan which only kicks in every now and then, so the only real issue here are the steppers overheating.

And thank you smile

Re: Home assembled SD2

about them dang screws... I talked to some family over holidays that are in CNC biz and told them we are having hard time finding them at all much less for under .80 cents each. asked if they knew any still sold by the pound lol.

he just said McMaster carr has em just buy the 3 dozen needed there. LMAO he obviously has no concept of lower cost supplys or low on cash.

Re: Home assembled SD2

I've actually found most of the socket cap M3s at Home Depot. I cleared them out quite a few times.
However, they only stock them UP TO 20mm. Fortunately I found longer ones affordable at Inventables.com which stocks various parts for 3D printers and desktop CNC machines. Kinda got addicted to the sight. smile M3x35mm screws went for $6.75 for 10. Since they are located in Chicago, I *should* have picked it up, but didn't find the time and ended up paying a bit more..even slightly more than MC would have charged.

M3 screws longer than 20mm are hard to find around Chicago. I am currently running the new printer with only one screw that actually threads into the Z motor. My longer M3s came in today, so I will finish anchoring the motor this weekend.

Re: Home assembled SD2

Very nice build!  That powder coating looks sweet, any idea how much it costs?  I just looked it up and the one shop near me has a $110 minimum order, but that is a little more than it would really be worth to me.  I might look a little further away.  I might build an SD3 from the ground up like this too and I would love to get it powder coated if the price is right.  But I could even get it blue or something, that might look cool...

Re: Home assembled SD2

I bought the frame off (the infinitely generous) elmoret as is. He said the powder coating ran about $60 if I recall correctly.

I like the plain metal frame since I can scribble notes onto the frame with a pencil, but this does look pretty swanky!
This was a fun build. I hope to have the time to post comparisons of stock/modded designs this weekend.
I will mention the frame can be quite difficult to get your hands on if you wanted to go as bare as I did with as little shop tool access as I do.
Hope I can do this again only with an SD3. Again...fun build smile

Re: Home assembled SD2

Yup, $60. I called a few shops, they all wanted $60-100.

I have an electric motor shop and access to plenty of machines and equipment. Do you think making some shells would go over well? It's incredibly simple

Re: Home assembled SD2

I think 90% of most 3D printing can be done on a 6x6 bed like an SD2. and its less space on a bench/shelf. you could buy an old 4 shelf rack out of a walkin cooler or commercial kitchen resale and have 16 humming on 1 wall in garage like I saw a guy doing in the UK once on youtube with the 1st gen makerbots. make a nice little factory to retire with.

Probably, if you could develop a reputation for quality.  The main reason I want a workbench printer (but may settle for an SD3 if they take much longer) is for the 12x12x12" frame so if you could build one of those for a good price and with excellent quality, I would buy it.  But I bet you would have to sell a ton of them to get your price per unit to an acceptable figure.

Re: Home assembled SD2

nah. I have tons of scrap sheet metal and a brake. The only real cost would be the pop rivets. Get me some demensions and I'll make one big enough for a 12x12x12

Re: Home assembled SD2

I wish I had a solidoodle workbench so that I could give you dimensions but I don't have one yet (no one does as far as I know).  If you had another solidoodle, you could scale the frame off that one if you wanted to start another project.
