  1. I hope I can get some good suggestions on how to improve my prints. Thanks for having a look, I hope this video helps explain. It's about 3.5 minutes but you might get the idea of what is wrong in the first minute or so.http://www.youtube.com/watch?v=cZME9TRrmeo&feature=youtu.be The model is of these thin tubes that are overhangs, so I tried to print with 100% fill density and thin layers (I am using Cura). The edges were curling so much that they were hitting the extruder fan, so I removed it. I didn't have it running anyways. The edges did end up curling anyways and the print failed. I also tried a simpler model that was a vertical extrusion (with default Cura settings), but that failed as well. So these are the questions I have now: 1) I thought I didn't need the fan and it was hitting the model, but does it help with overhangs by getting the plastic to cool instantly? 2) How do I stop the curling of the edges? I used a raft... 3) How can I stop the stringing? 4) How can I stop the delamination between layers? 5) Generally, what do i need to change to get good prints? I want to do some more prints later this afternoon/evening. Maybe I need to have a higher print temp., and print the infill before the loops.
  2. it seems like the activity is at the google group, if you have some advice i would appreciate it. Have a look here: http://groups.google.com/group/ultimake ... cf6d82e663
  3. it does have a little green light on at the bottom which is labeled "led 7", and the blue light at the extruder will flash on for a split second when i unplug the usb and plug it back in...but it is still not working I don't necessarily believe it is a software issue, but I tried using ReplicatorG Ultimaker Edition - 0035, and I have Python installed, but it does not help. It says "Couldn't find a port to use!". The Ultimaker does not seem to be turning on properly, the first time I plugged it in, without even connecting the USB, the blue light stayed on and the fan was operating, etc... I also tried a different USB, and I get the same thing when I plug it into the computer, the windows makes a "chime" sound for when you plug in a device, the blue light comes on the extrusion head for a sec, and there is a noise coming from the extruder head for a second, then it all dies
  4. I powered my Ultimaker on last week for the first time. Everything seemed fine, the lights came on, it was making wonderful noises, it was beautiful. I ran Cura, and the the first run check, and it communicated with my computer. I didn't run a print, and shut it down. Now it is a week later, I plugged the Ultimaker in, and the blue light at the extruder flashed on for a second, I heard it connect to my computer, but then nothing. There is zero activity. I thought I saw a little spark fly out when I plugged the power cord in. Anybody have thoughts as to what might be wrong? :?:
