  1. Just a guess, but seems like the set screws on those belt wheels (gears) on that axle are not tight. If they are tight, I think the axle should not move back and forth. I would gently move the print head away from the belt wheels zone til the belt wheels set screws are easily accessible and then tighten the screws on both belt wheels and see if that stops the sliding. Hope this helps! Mike
  2. That's pretty cool! Define 'absurdly high' with what nozzle. Thanks! Mike
  3. On my U2+ printer, I use a small bit of clear plumbing silicon grease on the filament holder spindle (get this from the hardware store/plumbing section). This makes the reel spin easily and the filament never pulls down between the other filament strings. (You could probably also use silicon spray on the spindle but the grease stays longer. I would spray the spindle with it detached from the printer). Hope this helps! Mike
  4. Thanks very much for the ideas! I ended up just building my own supports (which were similar to what the tree support was doing when there was just one object. They had a root which was mounted on an inside wall below the holes and 2 branches which supported the top of each hole). Worked great. Thanks again. Mike
  5. Thanks for the ideas! I tried spacing out the objects but this made no difference... with 2 or more objects, the external trees are generated. Just to be clear... I don't want trees that are external to the objects at all. I only want the small, internal trees that are present when there is only 1 object on the bed. If I have 2 or more objects on the bed... the external trees are generated. I think the answer is to make my own supports with little trees inside the object (like what Cura tree support creates when there is only 1 object present). Thanks again. Mike
  6. When adding the second object... the external tree structure appears. (Would be nice to have the option to toggle the tree structure display in solid view prior to slicing the objects). Thanks! Mike
  7. Here's some images illustrating the problem better: A single object sliced produces only internal tree support for the holes (as desired). Multiply the object so that there are 6 objects instead of one... and a massive tree structure now appears adding time to the print where this structure is not needed. Any way to force NO external tree structure and only have the internal tree support (as in the single object)? Thanks! Mike
  8. Cura 3.2.0 I'm really liking the new tree support! (Had one project where just changing to tree support dropped a lot of time off the print time). But there some things I don't understand about it. I took object above and put it vertically on the print bed and printed several test prints. On each, the object printed fine and had little tree supports inside the tube near each set of holes (nothing... no tree supports outside the object). I pulled out the tree supports when done and all was well. Then when it came to the final print, I put 16 of these objects around the bed and went to print. This time, rather than printing as before (with the tree supports inside the object), the objects were printed with elaborate tree supports outside the objects. This added lots of time to the print (and material) and was unnecessary as proven by the test prints (as they came out perfect with just the interior tree supports). Any idea why these supports were generated differently just by multiplying the number of objects desired? Thanks! Mike
  9. Thanks for sharing these tips... greatly appreciated! Thanks again. Mike
  10. I also want them saved with the profile (as in the old Cura). I also would like the option to save them independantly. But having to re-enter these setups every time the profile is opened is absurd. Thanks! Mike
  11. Awesome Constitution model!! (and I see you must be a Wramblin Wreck as well! My dad went to GT and his naval retirement ceremony was on the deck of the Constitution on the 4th of July). Great work!
  12. Good to know! Yeah, my UPS is about 25 years old (but I've replaced the batteries twice and last time was just a couple of years ago). Thanks for the info and print updates!
  13. Bummer indeed... sorry to hear that. Very nice looking print there though! It will look fine when you splice it together. Hadn't really thought about the power outage issue as I haven't had that happen yet to a print. Was your UPS not able to keep the printer going or was the UM so sensitive to the spike that it killed the print? I've got a big UPS but don't currently have the UM2+ plugged into that... will rectify that when(if) my current print finishes.
  14. Very nice. Don't keep us in suspenders! Hurry up!... (and wait). (I wish I had 2 Ultimakers!).
  15. +1 I don't know how many times a day I am happily orbiting the 3D scene in my 3D app using my SpacePilot and then move the mouse over to the Cura window and reflexively torque on the SP knob expecting to orbit the print bed scene. Takes me a couple of torques for the brain to remember that don't work.
  16. Thanks very much for this info! I see now. I definitely would like to be able to Reload All Models so that the modelling changes would be easy to incorporate into the existing project. As it is now, I must open the project (to get whatever settings the project contains) then pull the newly modified models into Cura while deleting the old models within Cura (all the while not getting the models mixed up as the modelling changes can be very subtle and hard to spot)... a hassle indeed. Thanks again. Mike
  17. OK, I found a line in the manual that implies that the models are embedded into the Cura project file. So that means that when I open the project file, I get the old version of the models. I would have thought that Reload All Models would reload the original OBJ files from disk thus showing the updated modelling changes... but when I do that, the modelling changes do not seem to appear. Thanks! Mike
  18. Cura 3.1 OK lets say I had a project file that had 6 objects on the print bed. When the 6 objects were originally dragged from the file browser to the new Cura project, they were: Object1.obj Object2.obj Object3.obj Object4.obj Object5.obj Object6.obj Then I saved the Cura project file. Then later, I make some modeling changes in my 3D app and re-save out all 6 OBJ files again to the same filenames. Then I open the Cura project file from before and choose 'Reload All Models' while watching closely to see if the modeling changes I made appear... they do not. Am I misunderstanding what Reload All Models is supposed to do? When Cura saves a project file, are the 6 OBJ files saved within the project file or are there merely pointers to the actual original 6 OBJ files? Confused. Thanks for any ideas! Mike
  19. Thanks for the info... interesting. I would certainly vote for seeing that back in the current version! From an automation standpoint (which was really why I was asking about this originally), I have found that changing to OBJs in my 3D app (instead of STLs) allows the use of some scripts to automate the saving/naming of multiple selected objects. So basically, select 10 objects, click 3 buttons and 10 OBJ files appear. Now drag all 10 into Cura and they can be shuffled around the print bed quickly. So this may be a current workaround for me. Thanks again. Mike
  20. Thanks very much for this info. That's what I thought. I will look into 3mf as well. Thanks again. Mike
  21. Cura 3.1 I'm pretty sure this is not possible but I thought I'd check. When you have a single STL (which is made up of 2 sub-objects) on the print bed in Cura... is there any way of selecting just one of the sub-objects and transforming that sub-object around the bed independent of the other sub-object? (Not sure if this would defy the laws of the STL format or something). In my 3D app, it would be convenient to select 10 objects and save them into a single STL. Then I could load the STL in Cura then select the individual sub-objects and shuffle them around the print bed to then have them all be printed at once. As it is now, I must save the 10 objects individually to 10 different STLs (which involves typing/naming all the STL files, etc.) and load them all into Cura before I can shuffle them around. Just thought I'd check. Thanks! Mike
  22. Thanks very much for the ideas. Bummer. Well, hopefully in the future... man will have options to control the blob! More specifically, I hope Cura enables more options to control the blob in the future (like squirt for N seconds, etc.). I will have to try without the blob to see what it does. Thanks again.
  23. Is there a setting in Cura to control the initial blob? Like 'squirt the blob for N seconds' or something? I would like to control the squirt so that the blob is only extruded for half the current amount of time/blob. Thanks! Mike
  24. Thanks very much for this info! I think I screwed up by accidentally saving only a .3mf file instead of a .curaproject.3mf file as when I go to load the .3mf file, it won't contain all that I wanted to restore for this print. Oh well... live and learn! Thanks again. Mike
  25. Cura 3.1 When I go to save a project, I sometimes click Save As... and I get a .3mf file. If I click Save Project... I get a .curaproject.3mf file. I'm assuming that the more comprehensive format is the .curaproject.3mf format? What is the difference between these two? Should there be some menu separation or more descriptive text to ensure the user get's the file type they want? Thanks! Mike
