  1. I went through all of these problems too and I've come to some conclusions based solely on my experience. PLA manufacturer and filament color matter, Hatchbox technical support actually said their filament is not compatible with the Ultimaker line. I've had the same brand of filament act differently, black was very viscous and sticky, printed wonderfully and stuck to the bed, then red wouldn't. I tried glue, no glue, tape, and weights on the brim all to get it to stick. Different brands and colors leave behind variable amounts of residue after a print. So when I have a fail like your describing the first thing I do is remove the glass build plate and wash it with dawn. Try not to touch the glass with your fingers, reinstall the built plate and level it. Try your print again with a slower initial layer, I sometimes slow down to 20 or 30% speed until that first layer is on the glass then crank it back up to 100%. And Gr5 is right too the lines should be smushed together more. Hope this helps.
  2. Every print has had some problem. This happens to me when the bed is oily from a fingerprint or other contaminate. My Ultimaker can't print two times in a row on the same spot, the filament leaves a residue that keeps the next print from sticking. I have to take out the build plate between every print and wash it with dish soap. Then reinsert it and run the bed leveling procedure.
  3. I love the salt idea, right now I've been squeaking by with a raft and glue smeared everywhere. I started with the thin film of glue like in the instructions, that wasn't enough. I just had a print fail today because the raft didn't stick to the glass.
  4. I'm working on a model of a building and all the parts keep warping. I have tried cleaning the bed which didn't work, I put on a new glass bed, it made it better for three prints and now it is just as bad as the last bed. I have releveled the bed every time I changed the bed. I rotated the model to have less surface touching the build plate, I changed the layer thickness thinking that a thicker layer would adhere better, then I tried glue and the glue print failed faster than all the others. I have tried Hatchbox, Ultimaker, Lulzbot, and Gizmo Dorks filament. I assume everybody is thinking that ABS has a lot of shrinkage and that is true I have fought with ABS before but I am printing with PLA. What is the next thing to do when everything else has failed? Maybe I'm making a stupid mistake somewhere so I'll try to include as many details as I can. I have not changed any PLA settings in the Ultimaker 2. Details: [/media][/media][/media][/media]
  5. OK, I am trying to build a rocket to show the physics classes, started with a simple cylinder and did a .8mm offset, extruded to 65mm tall. Added a .4mm ring to the top of the design to keep the motor from sliding through. The printer should just lay down two lines of filament in a circle, done! Unfortunately no matter how many times I level the build plate it is not starting close enough to the glass to get the filament to stick, and it is completely ignoring the brim I told it to do. It just runs in a circle extruding plastic into smushed circles, never getting any taller until it separates from the build plate and starts wandering around. I really wish there was a straightforward way to upload .stl files and gcode. I could really care less about emotacons. STL file, if this works gcode, if this works.
  6. Okay, this all took a new direction. I followed some of the wonderful advice given above and changed settings, I even did a factory reset. Nothing worked, just failed print after failed print until I finally got one to work. How did I do it, I changed filament from gray to black. It was the Ultimaker filament the whole time. The Gray is so brittle it was shattering in the Bowden tube and little bits were jamming the hot end and the pusher motor. It would be pushing filament up the tube then crack off a piece and wedge it just above the grinder wheel and that would be the end. So I took everything apart to get all the little gray cylinders out of the motor housing and hot end, switched to black filament and it printed the first try and hasn't failed once since. Both Filaments were ordered at the same time and opened at the same time in the same dry place at the same temp. The gray was just bad filament.
  7. GR5 I used the image gallery and all the pics are still in dropbox and Google drive, I didn't move a thing. I'll try it again. I also discovered all kinds of problems that I didn't know I even had. I lost one of the Bowden tube clips and could not figure out where it went, and in trying to solve this problem I discovered it has slid down to the teflon coupler and was sometimes impeding the Bowden tube from seating in the coupler. Then when I took off the fans I noticed discoloration in the shape of the block on the shroud. When I installed the block I cranked it down so hard I though I was going to break the threads and yet it never fit under the shroud and even though I made sure the nozzle was center in the hole I think the whole block was touching. So it was over heating the filament in the tube above the hot hot end and then when it cooled the filament created the blockage that was causing the grinding. I could shove the filament through but the moment it did any amount of printing the clog would happen again. So I abandoned the Olssen block and installed the block it came with and then I changed the suggested settings. Getting ready to start, crossing fingers.
  8. Well I tried to add an image gallery and include images through shared dropbox links and nothing looks like it works so I'll try to share with Googlehttps://drive.google.com/folderview?id=0B6Qt_aaNkZ8kbDV3YnBJVUIwSlE&usp=sharing Advanced Settings.tiff
  9. Here are screen captures of the settings used, but I can't get the little robot sample to print without the flow stopping midway through the print. Yes there is grind and yes I break it off and start fresh because the filament won't move past that point. I also have tightened and loosened that adjustment from as loose as it can go to as tight as it can go with no significant change in frustration or outcome. The printer worked for the first three weeks and nothing but failure since. Here are all the settings I know to find, I hope someone can shed some light on why we can't shove hot plastic through a little hole.https://www.dropbox.com/s/j3lzqqw5c91p3w9/Basic%20Settings.tiff?dl=0 Advanced Settings.tiff[/media-thumb][/media-thumb] Advanced Settings.tiff
  10. I have had two long prints fail, one late and the second almost immediately, each time I removed the bowden tube pulled the filament out and I could see that it was melted at the end but flat. I reinserted the filament and just applied pressure until filament extruded. So why couldn't the Ultimaker do this? After the first fail I restarted the print and it failed again in about 60 minutes. Do I need to do some cleaning on the nozzle? This is only the third print through the nozzle and the first one worked perfectly. So far I have adjusted the tension on the feeder and that didn't change anything. Ideas?
  11. I'm just starting out and I've made a few things successfully and now I was trying to see if I could make something big. So I did this complicated design in SketchUp and I thought it might be a good idea to try a 1/4 scale print just to make sure it was good and it literally printed a gray ball of fluff. So I backed up to the basic shape I started with and found Solidworks2. Checked the mesh for holes and it printed it out (see picture, shape on the right). Then I went to the next step and added a couple shapes and ran it through Solidworks2 again. When it printed it went back to a giant blob (see picture,shape on the left). I'm just not sure what to do next? Here is where it gets really complicated, I have to use Cura 17.10 because the computer designs for the Ultimaker2 and the Lulzbot Taz 5. You just pick your machine in Cura and it loads the profile of the machine you are outputting to. I'll open to any ideas at this point I've been beating my head on the desk for 17 days trying to get this to work. I've thrown it all away and restarted from scratch four times.
