  1. Is this what you were referring to? I have also posted an image of my run time stats, I didn't realize this was a wear item that needed replaced. I will try to make a test print tomorrow in Cura for comparison.
  2. Hello, I have owned my UM2E+ for about a year and half now and I have never been able to utilize the full volume of my printer. I have pretty well tuned in high detail and engineering grade prints a higher resolutions but I have never been able to successfully print much beyond 0.1mm layer heights. Every attempt I have made has massive amounts of under-extrusion between the layers causing the print to either fail or be incredibly weak upon completion. This increased layer height should very well be achievable on this printer and should enable me to make much larger prints in "sane" time frames but I have yet to figure out the settings on this thing to print at lower resolutions. Could someone take a look at the settings I am trying to run to see what I am doing wrong here. I am running Simplify3D and printing the Buster Sword model from MyMiniFactory.com with MatterHackers white ProPLA at 0.2mm layer height. Photo gallery of the model I am attempting to print as well as my settings in Simplify3D Thanks!!
  3. How does the controller find Z Zero? I am using feeler gauges to level the bed and I am wondering how thin is too thin? If I use a .0015 gauge to level the bed does this create an issue with the extrusion on the brim and first layers? It would be helpful general knowledge to know how the machine records its set positions from home (0,0,0) and if this is pre-programmed into the machine or if it is recorded during the bed leveling procedure. Thanks,
  4. Hello, I'm obviously new here and new to the 3D printing game but I recently bought an Ultimaker 2+ Ext and I am looking to both tinker and produce usable mechanical components for the FIRST robotics program I mentor. I am an engineer by trade and I know the typical applications of plastics like POM, ABS and Nylon for small mechanical components and I'd like to apply some of this to the demo pieces that I print. The biggest issue I see going through most of the material forums both here and on other sites is adhesion to the build platform due to warping. Now that I have my printer and I am starting to experiment with POM I can see the difficulty in getting this stuff to stick. I've been reading about other such tricky materials and I keep hearing about printing on wood, cardboard and different types of tape. My mind keeps wandering to these materials being useful do to their ability to entangle the initial layers of the print and if is the case why not use some kind of preformed mesh? I'm thinking anywhere from fine aluminum screen door material up to Bunsen burner steel mesh, something the material can wrap itself around when the nozzle pushes it through the mesh. I imagine cost would be an issue with the mesh most likely being completely sacrificial as well as using a raft on all printed parts. Am I completely out in left field with this idea, or does it have merit? Has anyone tried to print on a mesh surface before? If so how would I account for the mesh thickness in the first layer of the raft setup in Cura? Thanks, I'm looking forward to digging further into what this machine can really do.
