Line 13: − + − I also bought a few lots of these, you can ask the guy to remove the gears for you before shipping. They should work, but I haven't actually tried them yet!+ − Line 24:
Line 23: − + − + − − Also, there's the MacGuyver option... I'll have to find a photo but I know a fellow who has used the bottomparts of a clothesiron to make a heated bed that works great. − + − − This can be sourced too many ways to list. :) − I am using "Sanguinololu" on my current builds; it is smaller and cheaper:+ − The easy way to source this, or probably RAMPS, is to get ont he #reprap channel on IRC Freenode and ask. − + − + Line 57:
Line 51: − − I'm using the Makergear hot end in my current builds and it's very nice. I have ordered a couple of the Arcol to try out, but it takes him longer to ship, so I'm still waiting on those.
→What you'll need to acquire on your own to complete the build:
* Steppers (you will need 5):

These are what I'm using in the current machines and they work great, but possibly a little pricey, and overseas shipping:

These should work, but haven't been tested yet:

1/4" MDF works just great to get started. I'm using 1/2" MDF because it's what I had on hand, but it's a little heavier than it needs to be.

You might want to get a heated bed; PLA prints just great with no heated bed, but a heated bed is pretty much required for ABS. I haven't purchased any heated bed yet, but there's two interesting ways to go I am considering:

By all accounts, this is a fine heated PCB that's ready-made:

Another good choice is "Sanguinololu"; it is smaller and cheaper:

These are great stepper drivers and frequently sold out, but still ship within a reasonable timeframe on backorder. You'd do well to get heat sinks for them, too. There are many suitable options, but I am currently using these:

Hot end nozzles come in a variety of sizes; I recommend starting with a .5mm nozzle and getting a supplementary .35 or .25 later on. I've only actually /used/ .5mm nozzles ever, personally, although I have some .35mm here I mean to try out 'someday.'
