So I made a wedge with a 10 mm base to a razor edge, 70 mm tall and sliced it with Netfabb. I haven't printed it but I looked and the simulation and looks like the wall slowly comes together until it stops infilling and for a few layers does a hollow section with just an outline. Then it looks like the outside and inside contours but against each other and then overlap until it only traces a single line, interestingly it does that for only a few layers then stops short of the intended height of the object for several layers, I assume the wall thickness is less than .4 at that point (or whatever the width of a smashed flat .4 extrusion is) and so it just doesn't place any plastic. I doubt there would be much noticable difference in the wall surface, but the height might not be what you intended, nor as razor sharp. -b

Just so you know, the tube is PFA not PTFE, PFA has a higher melting point than PTFE. McMaster-Carr sells it by the foot in the US. Not sure about the EU. http://www.mcmaster.com/#pfa-tubing/=f0wc6h -b

Even if they did offer the kit in two sub 1000 kits wouldn't you shipping twice? So pay an extra 200 in shipping on a pair of kits you hope they will offer, or, 250 for duties and get it the regular way, all in one box. Not a big difference to me. You could try to build it yourself and source the parts but that is pretty difficult to do from scratch. -b

Exactly as Daid said, no curling and the parts come right off after it cools to 40-50C. ABS doesn't want to stick to the glass at all but PLA and ABS can be made to be happy together on a heated Kapton covered bed. -b

I've got a reprap bed, I have to manually handle the heat as it's on a different power supply. But it fits fine. -b

Anyone noticed this? Most of my longer than 1 hour prints will stop during the print 6 to 10 mm before completion. Not always in the exact same place, but often very near the end. Netfabb seems to stop sending, the animated toolhead jumps to the 0,0,maxz on the screen, the heater stays on and the fan is left running. Happens with the most of the latest Marlin builds. Seems like I saw somwonw talking about this but now can't find a reference here or the google group. Any ideas? -b

It doesn't make the loud grinding sounds the original cupcake did but it does make bleep-bloop type sounds that most people compare to the sounds of "movie computers" from the 60's. I'm not sure what exactly is making noise, it must be the steppers but It's hard to pinpoint. My cupcake updated with polulo drivers is nearly silent now. (Much quieter than the UM.) But it does run at a fraction of the speed the UM does. I presume running the UM at 30-40 mm/s would quiet it considerably. -b

Yes the versions of marlin in the repG firmware area are very old and still have skewing issues. Git isn't so difficult for those not interested in setting up git on their system. Just download the arduino IDE then go to the marlin git page and click "downloads", the select the "download as zip". Extract that somewhere and sartup the Arduino IDE. Load the Marlin.PDE file. Under tools->board pick arduino mega 2560. Click the play button to compile it then click upload (second button from the right) It may need you to specifiy a serial port. Then it will tell you if the upload was successful. Hope that helps. Also you probably (if you haven't already) may need to upgrade the motors to the larger nema 17 ones. -b

New plugin smooth to check out. http://fabmetheus.blogspot.com/ Anyone already messing with it? -b

In my experience Netfabb is only slightly smarter, if at all, about jumps vs Skeinforge. Seems like something with access to more processing power like NF would you some advanced shortest path algorithms to cut down on stupid fills. But it doesn't. It even resorts to jumps when doing hollow objects that don't need a jump at all. Don't get me wrong I like NF, there are just a new set of stupid things it does. But it does things a whole lot faster than SF. (A lot faster) so there's the trade off I suppose. -b
