First 3D Printer - Some questions unanswered after lengthy research

Hi

The power supply is a standard industrial supply. The "best option" is one from Meanwell. The one that goes with the mounts is about $45 at TRC. There is a new one out that is a bit smaller for $34. Both are mulit voltage / multi frequency.

What ever you do, get one from a real distributor. That way you get a "real" one and not some sort of counterfeit.

Thanks for the reply, Bob.

Colin also mentions speaker wire. He provides link for it at RadioShack's website, but as far as I could see online they sell it by the spool and I have no physical access to a RadioShack store. Is there any way of finding couple of feet of speaker wire online or getting to the store will be my best bet?

Hi

RadioShack is pretty much a dead outfit. There are a lot of places that will sell you a relatively small chunk of 12 gauge high strand count wire. Amazon is one, there are many others. There is nothing special about the wire. Any reasonably flexible stranded wire will do. I'd suggest this is one thing you can pick up when you get home.

Expensive, but very nice wire. Ten feet is way more than you will need.

Colin had listed 16 gauge wire and you suggested 12 gauge. What would be the difference between the two sizes?

Hi

In the AWG system, the lower the number, the bigger the wire. The wire on the heated bed is 12 gauge. Extending it with the same thing makes reasonable sense. Nothing else on the printer requires anything close to that fat a piece of wire. 18 AWG would be fine for the rest of it. You will also need a power cord for the gizmo. A used computer cord with one end cut off works fine. For the insulation on the bed, Nomex felt is a good choice.

There are lots of other ways to go for that.

The Titan appears to be a fairly new, geared extruder from e3d. Looks promising. No one has posted in the MakerFarm subforum about using it on a MakerFarm printer yet. Note that the "standard" extruder on Pegasus is a direct drive, without any gearing. Because of torque limitations from the extruder stepper motor without gearing, that limits you to 1.75mm filament.

The insulating material goes between the heat bed and the Y-bed plate that the heat bed sits on.
