Muffin CNC

I know this is an older project but what psu did you use?????? :)

I don't have a model number. It's a power supply that fits in a 1U server.

Will the Muffin CNC be the next generation Cupcake CNC? I like the Muffin so much more than the Cupcake! If so how much will it be and when will it be released?

To save space, would it be possible to use any of the power supplies here:


It looks like they can custom configure the wire harness...

Those are neat. As DC-DC converters, those would work great if you have a DC supply -- but they can't convert mains AC current.

I tried it with one similar to http://www.morex.com.tw/products/imgproduct/62-1.JPGhttp://www.morex.com.tw/produc.... I chose the internal power supply, so I wouldn't have to carry around a wall wart.

I like how using an external AD/DC converter would increase the build volume. I'll consider this for the next one.

I have used these in desktop mini-itx PCs using an external power brick. Wouldn't that work ok in this case?

Totally, though that's really just moving the power supply to the external brick. :-)

But it makes the Makerbot smaller...harder better faster stronger :)

Seriously, I can assume this might make more space to maybe enlarge the build area or just make access to the internals easier. Also no fan to add to the noise level.

Know what else? Moving the z axis drive system to the bottom buys you like three centimeters of build height by removing the stepper that would otherwise prevent the z-stage from moving further up.

actually we solved that by adding a motor sized cutout to the z stage :)

I actually just noticed that today when I was smoothing out my bot's the XY motio. I think that will be really nice for observing print jobs.

the second reason for the cutout ;)

I guess I'm going for a height record now.

Make sure the rods are well-oiled, though. Gunk tends to build up near the ends of the rods, so running the MakerBot especially high often leads to trouble if you don't have clean, oiled rods.

I'm also considering using acme threaded rod, so that might prevent some gunking.

Oh... oh SNAP.

Well played, Charles. Well played.
