Also, it lists the cabinet coach screws as 5mm. Does this mean M5, or 5mm long? And either way, what’s the other measurement?

I’m going to try to make a version that is compatible with SAE pipes but metric hardware. The reason for this is that in the US, it’s pretty easy to get the required hardware, either from physical stores like Ace Hardware or Fastenal, or from McMaster-Carr.It’s the same price for metric or SAE I prefer metric because it just makes more sense, and is much more practical than SAE. However, the metric pipes are more expensive than the SAE ones, and as far as I know the only place to get them is McMaster-Carr. I don’t know when I’ll have time to work on this, though.

On the new BOM, it doesn’t give a length for the 8mm smooth rod. How much do we need?

[evamvid]

WAHOO!

I just found out that the local hardware store sells loose Metric hardware!
(Unfortunately no metric pipes though)

No I don’t have to buy them in bulk from McMaster. This might cut my build costs anywhere from $30 to $100, depending on if they stock some of the less common hardware (like the fender washers).

JACKPOT!

How’d you setup the duct tape belts? That might be a really good idea for repstrapping; on some of the bigger repraps, belts can be a significant part of the overall cost.

Also, I know someone at the local hackerspace who says it’s not that hard to etch heatbeds yourself. The problem is, that would raise costs because you’d have to pay for the etchants.

He also said you can pretty much make heatbeds of unlimited size because you can etch smaller boards and tape/solder them together.

Also, the BOM says I need two 0.9 degree and 2 1.8 degree steppers. Since the cheapest way for me to get the steppers is in sets of 5, it’ll be much cheaper for me to get all of one kind or all of another. If they all need to be one kind, which kind is better?

Thanks!

Also, where is the exploded view of the driveshaft assembly. I know I saw it somewhere earlier, but now I can’t find it.

PS Thanks for taking the time to answer my incessant questions 🙂

I keep seeing references to 6805 bearings; but they’re not in the actual pdf BOM. I see a printed part labeled 6805 bearing adapter, though. How many 6805s do I need?

Also, there is Kapton tape in the BOM, and it says it’s used for assembly. Where is the tape used on the printer? Is it just used in the toolhead assembly?

[evamvid]

I feel like it won’t be that much more expensive to scale up the whole machine; and it would really make the Morgan a very attractive option; because I don’t think any well-documented Reprap has a build area that big.

Thanks!

How exact are the dimensions you have to use for mounting the pipes etc.?
Are there any? Or do you just have to make sure that they are stressed against each other?

[evamvid]

Also, if I went with belts for the drive, do you think I could make a full loop by hot-gluing the non-toothed side together?

[evamvid]

And what about the ported/non-ported pipe adapters? Are those a potentially printable part?

[evamvid]

For the copper tubing, are the diameters given ID or OD?

Blaze_1: I’ve picked up on that a little bit, just looking at all the different build pics on this site. I’ll definitely keep what you said in mind. At the same time, thanks for the dimension. I’m nervous in general about setting off without a predefined plan, so that really helps me out.

How big should the plywood be? And what is the radius of the semicircle you cut out of it?
