  1. Ah, I see. Seems like I had a limited understanding of the spiralize feature. I had always just adjusted the wall thickness to the nozzle-diameter, thinking that it would override it to that value anyway. Seems that by increasing the wall-thickness I may have more success in making things watertight, thanks.
  2. Hi Arjan, I recently got my hands on some XT clear and was already aware that XT can be quite temperature-critical to print. Looks like i'm going to have to do some testing of my own, only have a 0.4 nozzle though. Nice to see some examples of the difference that different temps and cooling give. Just a note: As I understand it, the spiralize function in Cura overrides the input for the shell-thickness. So if I'm not mistaken, all your tests would have generated G-code with a shell that is equal to your nozzle-diameter (in your case 0,8mm).
  3. The silvery color of bauermakers first print is probably due to his choice of abrasive. Usually when using Aluminium or Stainless steel it leaves a silver finish (when polishing like this you're not only taking away a small amount of material of the surface of your piece, but also slightly degrading your abrasive material, which leaves a residue on your piece.) also, congrats on your 'leet' number of posts
  4. Yeah, it's 'Margo' from the new production company 'Bold Machines' that Bre Pettis (I still feel strangely betrayed whenever I come across his name...) is heading now he stepped down as CEO of Makerbot. They have released the models for 2 of their characters now (on Thingiverse, obviously): Margo Mr. Walthersnap (The villian). and according to their blog they will be providing more models in the weeks to come. They seems nicely modelled and all are already broken up in individual parts and optimized for build orientation, I was rather impressed. Haven't had the time to look at them for l
  5. The endstop I mentioned is the little black block that's glued to the side of the case (in your pictures it's behind the metal bar). This is a limit-switch and there is another one in the same corner glued tot the roof of the printer; normally as the carriage is moving in a certain direction the printer needs to know when the edge of the buildplate has been reached so it can stop. This is when the limit-switch is pressed and at that point the motor should stop turning. The metal arm (/clicker) is supposed to be straight, however in your pictures the top part is bent, (If you check, the other
  6. The metal arm from the endstop looks awfully bent, did you do this yourself to correct some alignment issues? If not, it probably means the whole carridge simply smashed into it without stopping the motor. Could the continued running of the motor have streched the belt? (since the lower part of the belt is somewhat fixed inside that black slider-block, pulling on one side could make it longer?) Not really sure, just putting it out there, I do agree with Illuminarti that the amount of play is quite substantial.
  7. Alternatively, you could increase the Bottom/Top Thickness so it would have more layers to eventually fill the final top layer: Say your using a layer-height of 0,2. A Bottom/Top Thickness of 0,8 would mean creating 4 solid layers at a local highpoint of the print. The first layer wil sag and string severely, the second one would have little to build apon but more so than the first, same goes for the third and finaly you'd have to hope by the forth layer it will be solid and flawless. Increasing the Bottom/Top Thickness to 1,2 would give it 2 extra layers to even out the surface. I've been
  8. IIRC, the default height for the fan to be full on is 5,0mm, under the expert settings, I'm only 99% sure since I have been playing around with a lot of settings for the past couple of weeks so I may have changed this without me realising, but I'm almost certain the fanspeed scales linear to 100% at 5,0mm. I think it's along those lines. I haven't looked at the g-code that much, but what I found during prinitng was this: My settings have the fan start at 0 on layer 1 to 100% at height 5,0mm (usually this is layer 50 because I tend to print at 0,1mm). So after say 3mm of printing if I g
  9. Ah, I see, well never mind then, in the case of one-off's and exclusive designs printing them directly seems the to be the best option, I just wish I had any experience printing flexible materials for any further advice.
  10. I have never tried any flex-PLA's before, so I don't have any advice on printing with flex-PLA, however if commercial work or bulk production are your intent, why not print in regular PLA, make a mold of your PLA part and then use that mold to cast dozens/hundreds of the part in flexible silicon. 3D-printing seems to me as a less likely tool in producing bulk (it's strenghts lie in prototyping, one-off's and small production runs), espescially when increased detail usually means longer printing times and therefore lower production capacity. Instead, you could print in normal PLA and crank up
  11. hehe, yeah that arc is a tricky one :smile: as with all overhangs the general rule is cool and slow, for a specific feature like that I usually go back to 25-30 mm/s printspeed and around 200C. Also manually increasing the fanspeed during those last couple of layers in which the overhang is most extreme (just before the two halves of the arc meet in the middle) may help, although if you cool too much (especially the nozzle) you might harden the plastic before it exits the nozzle which will at first start to lead to under-extrusion and eventually a clogg. So it's one of those interesting bala
  12. I have the same versions of Cura and Marlin, and I also noticed that the LED Brightness settings are a bit wonky now. It's not that they don't work, it's just that they only activate once you cycle past them in the Menu on th UM2. A couple of days ago I set them to 50% brightness and as I did so, it changed on the fly. A day later, after a power-cycle, I noticed the LED's were on full and only as I cycled past the option "Led Brightness" in the Tune menu during a print, did the LED's immediatly change back to 50%. Didn't even have to open the option, just cycle past it. So it seems any chan
  13. Hehe, I had the same thing happening to me. I recieved my UM2 last Friday and was also surprised to only find the MiniCalTest.gcode on the SD-card. After I mentioned it in my feedback mail, Sander apologized, seems like a small hickup in the calibration department, after calibrating they forgot to replace their calibrating-SD card with the customer version. Still, I knew Cura came with that friendly little robot, so before moving forward, first thing I did was copy it to the SD card. It may be weird, but it kind of....felt...right, that my first print was that friendly blue robot that's now
  14. I apologize if my previous post implied that 'water soluable' meant dipping it in water would wash a support material right off. As Daid very accurately described, trying to solve a plastic like that is basically like untangling the spaghetti. (breaking up the polymer into many loose monomers). What your left with, is going to be 'snotty' mess who's viscosity depends on the ratio of plastic and amount of water used. I'm glad to hear that running it under a tap appears to be sufficiant to remove the slurry, although perhaps a more thorough aproach may be needed for hard to reach/flush places
  15. I've always been a fan of combining any dark grey / black with very vibrant yellow accents. It always remainds me of those industrial looking safety rails with the slanted black and yellow bands but in this case it also has a 'BumbleBee-thingy' look going for it, which should work well since it's going to be buzzing with productivity like any good worker-bee should :-P (I appologise if I come of as rambling, I just recieved some very happy news : Dear Customer, Your order has been shipped ============================== Shipment Summary ================================================
