I would prefer that if possible the device didn't get much bigger than it is now. Aesthetically, the 4.2.4 is a world of difference compared to the 4.0 or 4.1. If anything, I would love to see it get smaller but I don't see that being a possibility. On a side note, I will be posting the A+...

Nice work!

I have one on order and will adjust the existing supports and then add piA+ specific ones.

Cool. I'll make a case version that closes the ports for the piB and shaves that post a bit.

This is a nice write up by a former bell labs physicist who happens to love bbq. http://www.huffingtonpost.com/craig-goldwyn/physicist-cracks-bbq-mystery_b_987719.html

That's a great price

If you're that worried then just clip the ends of the propeller a bit with a scissor.

The fit is supposed to be very snug. I usually take a Phillips head screw driver and press along the holes in the propeller to snap it in place.

The Geeetech looks to be a clone of the E3d which I am a huge fan of. I agree about the bowden oozing concerns because they are not easy to deal with so if that compact i3 design is light enough I'd give it a shot.

It's not that difficult to setup but you have to sacrifice some part of your build area to compensate for the hotend offset. If you are going to do it, I would look into a bowden setup because pushing the mass of two full extruders will hurt your print quality. I played around with it for a...

The screw should just be tightened enough to hold the valve on. If you see chattering, it is too tight. The speed doesn't look off to me but your closed position does. The closed position should be just before the point where the fan wire hits the end of it's track. Try to make sure that you...

Matt is the other forum member that helped design the case. I haven't spoken to him in a couple of months and wasn't aware that he isn't making cases anymore. I try to help as many people as I can but my time is limited.

Joel, there are fairly clear instructions on what to do in the first post of this thread.

Sorry about that, I didn't even see that the extruder was fixed on the x-axis and that the bed moves in both x and y. Forget what I said about the filament strain relief stuff, the z-screw stuff still holds though. Just look up z-wobble and you will find tons of information. Tom

These issues are usually due to the threaded rod which is why you see this pattern with perfect periodicity. Trapezoidal screws are definitely a worthwhile upgrade but you can often fix a lot of it by making sure that you are choosing a layer height compatible with your pitch and by putting some...

Hey Dave, what is the pitch of your z screws and what layer height are you using? What type of z screws? This looks like z banding but you should see this in all of your prints if that is the case.

4mm is a huge retraction distance. Lower that to 2mm and see how it goes. You really want the retraction length to be as low as possible without having too much blobbing or stringing.

This looks like a retract problem to me. I've seen this before where certain layers in an object will slice in a way that there are a series of retracts that can foul the hotend. Look in your slicing settings at what you have set for retraction and in what instances you are using it...

Did you continue the test for longer? The reason I ask is that it appears from your graph that all of the fluctuation occurred at the first 2 hours during startup and then you finally reached a steady state, but I can't tell for sure with the limited time at the end. You don't want to tune your...
