  1. I think that your setup of that printer is well beyond mine (I still print from SD cards though I did have an single board micro driving a printer a while back)! I do have a UM3 next to my remaining 2+ though so I have you there! I am still thinking that I need an SLA or DLP printer but am holding myself back. I have so many half done projects at this point that it is getting silly.
  2. It is a lot easier than some of the other stuff that you have done with your printer! Just go for it...there must be a reason that the seller gave you a spare! I have done it numerous times without issue and it is easier now on the + than it was before. Did it help though? Will Haha, yeah it was super easy. Less than 20 minutes to change one start to finish now. Exactly! The pre "+" printer had a compressed spring that made it a little more exciting as once in a while the spring would come shooting out like a little rocket.

  4. That explains why I could not find it. I just rolled back from 2.4 to 2.3 because of some issues that I was having with my UM3 and 2.4 so i guess this will have to wait! Thanks, Wisar
  5. Where is this setting in Cura 2.3? Thanks, Will
  6. I have done quite a bit of work at the 1:100 and 1:160 scale but the stuff that I do are structural originals...like an articulated drawbridge or a windmill. The Ultimaker, with a 250 micron nozzle, is perfect for that kind of thing. What you want to do needs an SLA printer! Maybe you need both...but for what you are describing you need the resin.
  7. Reverted to Cura 2.3.1 and the problem has resolved itself!
  8. I did a cold pull and it came out remarkably clean. I guess there is something to be said for the UM3's handling of the print core! It made no difference as expected. I had been coming to the conclusion that I might have an issue with the Beta and had just done a test print that goes at least part way to proving that point. I am going to take your recommendation and revert back to 2.3 (clean). Are there folders hidden somewhere that I need to wipe? Thanks, Will
  9. My UM3 has suddenly decided to start oozing after months of printing perfectly. I am still doing some tests to try and narrow things down and will post some images later but first wondered...has anyone else seen this happen? I am using the same materials across a UM2 that is working perfectly and my UM3. I am getting the same result on both AA cores. I have cleaned the extruder driver (and it needed it). I am using the stock profiles from Cura. I am running the Beta but am pretty sure that this started before I downloaded it (test coming). I also have S3D so that is another test coming. I have not done an atomic clean and am wondering if I should. Just asking the question makes me think that the answer is yes! Any suggestions would be appreciated. Will
  10. My scientific method in regards to working on this problem, frankly, sucked. The problem does seem to have gone away but I am not completely sure why as I changed more than one variable at a time. I did do the adjustment for the bed per the post recommended by neotko but did not find this to work. On one occasion I cleaned the nozzle on the BB print core and a subsequent auto level did work...but on another occasion, it did not. Then, somewhere along the line, I upgraded the firmware on the printer and, this is where the method broke down, I am pretty sure that I had an auto level failure after the upgrade, but would not swear to it in a court of law. So, at the moment I am working fine............!

    One for each of the distinct materials that I have in my filament locker. Done at 150 micron resolution but for the Flexible Fox (300 micron) and the Fat Layered Fox (400 micron). There was an NGEN Fox in Black but he got thrown away!
  12. I am running the current firmware, just updated last week, so whatever version that would be.I would be fine with manual leveling if I had not had the failed dual extrusion print in the midst of getting the message that I asked about at the start of this exchange. Interestingly, I just did an active level and it failed. This was on a build platform that I just manually leveled to perfection yesterday. So I heated the core that is in slot #2 and then wiped the tip of the nozzle and re-did the leveling. It worked. Might be worth a try. I would like to hear some thoughts from someone at Ultimaker!

    This is a customer print that while simple does a nice job of illustrating what the UM3 is capable of printing. Note the undersides of the print where the support material had been printed...it is as smooth as if it had been printed on glass.

    First piece that I have done using Copperfill and still not sure how to best finish it. Used a Dremel with a brass brush at low speed then a polishing disk also at low speed. The process seems to work though it actually seems to highlight the layers!
  15. This happened to me as well. The good news is that the fix is reasonably easy to implement. I say reasonably because I am not that dexterous and found it somewhat hard to get the new slider on and so designed this aid: Ultimaker Sliding Block Fitting Jig Thing I only used it on the x-axis so am not 100% sure that it will fit the y-axis. I also found that wrapping the two cracked sliders with cable ties, secured as tightly as possible and positioned to not get in the way of anything, had me back running until I got the replacement parts. Will
  16. More on the above. I replaced the BB core with an AA core and the automatic leveling process worked. So I swapped cores again...and the leveling process worked! Even better my two material print with PVA is now well beyond where it had failed before........... :-o
  17. I manually level for single extruder prints and am fine with that though I still want auto leveling to work. My print surface is sparkly clean and the bed is adjusted manually and is not far from the recommended clearances between the top of bottom plate and the bottom of the heated plate. Yet the auto level fails and what is WORSE is that I just tried to do a two extruder print and IT FAILED! Looks like bad extrusion. The PLA side was just fine. Will
  18. Whats up with this message? Just started doing it out of the blue a couple days ago. Followed advice elsewhere on the forum about the distance from the build platform base plate to the bottom of the heated bed and still same error. Printer is working fine in single extrusion mode but have not tried a dual extrusion print since the error manifested itself. Help appreciated! Will
  19. I appreciate Tom's tactful response and would hope that he understands my point of view as a customer...one that worked for most of his career at a manufacturing company with a name most everyone will have heard of and one that has fought the occasional quality issue. It is all about process discipline, and of course, that includes learning from one's mistakes. I am back up and running, and the repair was not terribly hard to implement, but this is the second issue that I have had (first printer went back as the LCD display tipped over) and that is concerning after my experience with my two UM2's (flawless).
  20. Tom: I have to take a little exception to the language "probably partly our own fault". Ultimaker manufactures a product that occupies a premium price point that it can demand at least partly due to an expectation of superior quality. It is the Ultimaker name on the printer. If there is a bad part anywhere in a finished product shipped by Ultimaker then it is your fault as it happened in your supply chain and is indicative of a process failure! It is always nice to be able to blame a supplier but it is the Ultimaker name that will suffer regardless of the excuse. Just sayin'[Above statement comes after my spending of hours fixing a new and expensive printer that had been down for days.]
  21. Replaced the cracked blocks on my printer. Am curious as to the cause of the failure. Obviously I am not the only one impacted. Anyhow. Replacing sliders is really fiddly. For me anyway. So, being a 3D kinda guy I designed a couple of parts to make slider replacement a little less fiddly. No expressed or implied warranty! Ultimaker Sliding Block Fitting Jig Thing
  22. How about a cloud based repository of profiles with user feedback incorporated. Uploaded by any registered user of this website. Defined by (and searchable by) the printer, material, and whatever else makes sense. Voted on by users as to whether they actually work or not. Authors develop credibility when they upload profiles that are scored well. Authors with credibility automatically have a quality attribute of new profiles set to something above zero with feedback also contributing to that quality attribute. Users can search for profiles with a certain level of quality. Ideally accessible from within Cura with the search capability mentioned above.
  23. Is width alone enough? I guess Cura will adjust the flow rate to compensate for the larger width?
  24. Thanks. I have uploaded the print with some comments as to the configuration that I used (which was S3D). I have not done a print with this material yet in Cura but having just looked at Cura I am wondering how to handle a nozzle that is not one of the selections. Do I manually adjust stuff like extrusion width and flow rate to account for the 500 micron nozzle that I use or is the nozzle size accessible somewhere and I have missed it?
