endstop switches - 3 needed, ebay or see Dan Royer
Power Supply, either an ATX or a slim style LED
Tinkerine have a 15A or ebay vendors.
$40.00 Canadian for a 30A from a ebay vendor in Ontario with free shipping: http://www.ebay.ca/itm/261704139766
For the hotend we bought a genuine J-Head from MakerFarm
Wiring kit - ebay or AliExpress
16 or 18awg wire for wiring 12V to RAMPS and also heated bed and hotend - Princess Auto
They only have 5/16" stainless steel rods, which aren’t chromed or precision. So you’ll likely end up with bearings pitting the rods and having issues.
There should also be sets on Aliexpress for similar stepper motors that come in lots of 5, you just need to make sure you get the right motor length and amperage. RobotDigg also seems to have some fair priced steppers which I plan to try out.
Do they carry precision rod though? I don’t see anything like that on their site. I do however have a few year old HP printer that went for poop, if some one wants to blow that shit up for some rods.
I did buy M8 smooth rod from a 3D printer supplier out of Ontario, but they screwed up the order so badly I don’t want to recommend them. What we bought from the AliExpress supplier was better quality than what we got from the Ontario supplier but cost more.
So it looks like the M8 Smooth Rod may be the most difficult to source…
I have started getting the various parts and bits (thanks for the link to the power supply)…
I’m going to try to build one of these printers as well.
I’d thought about building one before, but it was too overwhelming a job to do alone. (This was before I found out about the Hackspace and the local 3D community.)
I just received some beautiful case hardened 10mm x 610mm shafts from Rotoprecision. They’re precision and straight as an arrow. $80 for 6 including shipping.
Any thought/recommendations/comments on hot ends? Sizes, types, etc. I’m leaning towards the Hexagon 1.75 (available at a good price from Dan Royer) but would welcome any advice. My needs are pretty generic as I’m sure I’ll want to try different types of filaments, etc…
@ashley - Good info on the Rotoprecision source. I have ordered some 8mm from AliExpress but will try this place the next time (if there is a next time)
@packetbob, If you are just starting out and plan to print mostly PLA and ABS, then I recommend a genuine J-Head. All-metal hotends like the ever popular E3D and the hexagon are great for high temperature filaments but there is a slightly higher risk of filament jams since the metal bore must be very well polished to achieve the same low friction as the J-Head’s PTFE liner (this is ultimately what separates the good hotends from the bad, that and heat dissipation / heat creep). It is recommended that you season all-metal hotends with oil prior to use, especially for PLA. With a J-Head, you just install and go and you will have zero problems with it. The heating resistor used in the J-Head is also, IMHO, a little safer than the 40W ceramic cartridge that you find in the all-metal ones.
