Untrue!! I've been running basically the same profile since SF26 or so.. Sometimes Enrique moves things but moving profiles forward to new releases always works for me.

My MakerBot Cupcake pretty much choked right out of the box. A mosfet on the extruder controller smoked almost right away and, well, it came with MK4. MakerGear parts and support is what got my MakerBot working. Rick was on the MBI google group and walked me through my MK4 problems when MBI was totally missing from the support scene.
I've never had a MakerGear product fail. Even though I'm not r

Layer height is a vertical thing, nozzle diameter is a horizontal thing..
Could you take, say, a fire hose and put it 1mm above the ground and have it work? Sure, as long as the pressure wasn't tur

Most people print in PLA but I don't think there's any reason you couldn't use ABS if you wanted to.

You've probably got different temperature settings for different parts of the print.. SF will add gcode to sorta wander around a bit and waste enough time to get to the new target temperature before continuing printing.
Dunno sfact but in SF, you can either change the heating/cooling rates ("set but don't wait") or you can not use different temperatures.

Excellent idea, as long as the detailed bits are on layers that don't take long to print. And that does indeed seem to be the case on the object he's trying for..

At the risk of restarting the MDF-is-a-sponge discussion, another option is that the cat will pee all over it..

Honestly, I'd forget that calibration object. I was never a fan of it and think it makes even less sense now, SF40+.

Heya Richard.
Looks like a couple people have said they've received tracking numbers. Does this mean that we're going to see pictures of people opening up Sumpod boxes within, say, a week from now, guaranteed?

Possibly not what you're looking for but:
Most of these are from netfabb, not SF+repg, but I think I know how to do most of this in SF.. Are there any outstanding questions on this stuff? Have you tried turning your layer height way down???

Never seen that before.. Bizzare.
Usually, when SF wanders around without extruding, it's doing it for some temperature-related reason.. Either the Cool module is enabled and the layer is going to take less than the minimum time to complete or you've got Temperature settings that tell it you want different temps for different things and it's wasting the time until it thinks (based on the set coo

I think that depends on if you're setup to have 0/0 at the min stops or at the center of the platform. If your center is 0/0, the defaults in Multiply work just fine..
> Nobody else head problems with too big parts being printed?
I don't. I usually just look at the summary skeinforge prints when it's done, where it tells you the min/max values used for each axis.

> perhaps a possibility of choosing ''start from center'' can be addet?
I don't know of any way to have it verify that the build will be within the limits of your machine but if you activate the Multiply module and set both rows & columns to 1, it will center and floor the print for you. This is one of those modules that I always just leave enabled.

Looks right to me. Between that and the other numbers, it seems like you're targetting (on purpose or by coincidence) a thread width that's the same as the nozzle diameter.

Heya Paul,
"W/T" is sorta skeinforge-talk for thread width.. It's the thread width divided by the thread thickness (aka: thread height). With thicker layers, this value is an important component of how strong an object is because a higher w/t ratio means more contact between threads on subsequent layers. That's a bit of an over-generalization and there's more to it than that but it's sorta close

Feeling like you've been scammed, even if you do manage to get your cash back, sorta is personal.
With the site being down for several days now, the lack of forthcoming info on what's going on and all that, I can see how people might think this IS a scam. It's not like this world's short on scammers or anything. I hope it's not but can see how people might think it is.

Yup. (higher res: ∂=4) is an example of this. Sliced with netfabb with a 0.02mm perimeter and 0.04mm infill. Yes, cheating a bit wit

: 0.10mm layers with a 0.5mm nozzle on a DC-extruder Cupcake..
: 0.20mm infill/0.10mm perimeter on a 0.4 nozzle, Ultimaker. Can't really see the details, though.
I like those spiral bevel gears - may give that a shot this weekend..
Also still think it's worth the time to do the whole first layer slowly, especially if you're new. That said... yeah, 6mm/s is pretty slow. I'd do it anyway, thou

Strongly disagree!! The ones in speed are for the whole object. These above are just for the 1st layer and slower = better there..

> Anyone has actual experience on both sizes?
I don't.
In theory, 1.75mm is more consistantly sized while a spool of 3mm can vary in diameter more.. Maybe it's 2.85mm in some parts and 2.90 or 2.82 in others while 1.75 sticks pretty close to 1.75. I don't know that anybody's actually tested this but I believe it.
Also, since you get less volume per extruder step with 1.75, you should be abl

They ship a 3mm rig but I think it should be able to make it work (with parts) with 1.75mm, as long as the Bowden setup is ok with it.
I continue to be unconvinced that 3mm vs 1.75mm makes any real difference for +99% of us.

What about 100mm? This e_steps_per_mm is really important to get dialed in as closely as you can.. If you can easily pull the hot end off, do it - there's no need to a
