  1. Same issue here. First print job on the new S5 that actually required precise alignment of screw holes. Spent about 10 minutes scratching my head, thinking my PCB was not symmetrical or was mis-cut, then I check the square on the part and it was off by about 2 degrees. Printing the larger alignment pegs now (had the 8mm ones already for my 3E), so I will try to re-do the alignment tomorrow.
  2. It could be related to the firmware version. I have not updated my firmware in 9 months or so. I will try to post the firmware version currently on my machine later this week.
  3. Thanks. That makes sense based on what I have read on the S5 setup.
  4. Here you go. You need one base, and two arms. Arms clip onto the base. I usually only print with a single material, so I never bothered to make on for the extruder 1 filament spool, but I may do that in the near future. I will keep you posted if I do. Enjoy!

  5. I am finally getting around to posting this. We bought our UM3E about 12 months ago. The first time I ran a print over night, the filament jumped over the edge of the spool, got bound up around the spool post, and caused the print to fail (in the last 60 minutes of the 20 hour print job). I was very frustrated. So I designed a simple add-on to prevent this from happening again. The factory equipment restrains the filament at one point around the spool, leaving it free to jump the spool around the rest of spool. To fix this, I created two additional restraint arms. To make sure it fit correctly to the existing components, I downloaded the part CAD files from Ultimaker. It fits over the spool post, and positively locks into place against the existing retainer arm (to prevent it from rotating with the spool). When changing spools, you just sit the retainer on the side of the spool, and load it normally. A little turn ensures it is locked in.
  6. I think in both cases it was following an aborted print. Interesting. I will add that to my workflow to make sure the printer is power cycled after an aborted print. Hopefully that will prevent that from happening again.
  7. Twice in the last few days, I have started a print on my UM3E, only to have the machine basically stall during the initial filament purge (the glob it puts down in the front/left corner). In both cases, I had to shut the machine off to get it to stop. Normally, it purges for a few seconds, then lowers the print bed a bit while purging for a few more seconds, then moves to begin the actual print. The total time is normally no more than 10 seconds. The first time, it purged for about 30 seconds (at the initial height, and never lowered the bed) before I realized what was happening. It made quite a mess on the nozzle. After that was cleaned up, I started the print again and it worked fine. Today, I went to run another batch off the same G-Code file, and it did this again. I caught it quicker this time, so less of mess. As with the previous time, I started the print again and it worked fine. Any ideas? I have had this machine for 12 months, and have never seen this before. The firmware has not been updated recently, and the same Cura version has been in use for months.
  8. OK, so as I typed the original post, I realized I should have checked a 3E profile setup. Using the 3E profile, the default file type is G-Code. The UFP file type can be selected as the file type for the 3E. It appears the default file type for the S5 profile is UFP, but G-Code can be selected from the file type drop down. Still wondering what the UFP file type is, and what it is used for.
  9. I just updated by Ultimaker Cura to version 3.5.1. After I get a print set up in Cura, and I save it to my desktop for later use, I noticed the sliced file is being saved in a *.ufp file format, instead of the *.gcode format that my previous version of Cura (3.1.0) saved as. Is this expected? I am not familiar with this format. Cura does not seem to recognize this file type (as in I can select Open File in Cura, and it will show me all the saved G-Code files, but not these new UFP files). I have not saved any new files to my thumb drive yet to use on the printer. The files I am working with are using the S5 profile so that I can see how many extra production components I can fit onto the build plate on an S5. I currently have a 3E, so I am trying to convince my boss to get an S5 to increase our production capacity, as well as to take advantage of the new features on the S5 (particularly the "fully supported" composite materials and the new CC print core). Anyway, maybe the UFP file format is exclusive to the S5 profile? Any help would be appreciated.
  10. With the new UM S5 coming with both a glass and aluminum build plate, I was wonder if Ultimaker will offer an aluminum build plate upgrade for the UM3 line? My firm exclusively uses engineering materials for our prints, so that aluminum build plate would be a great time saver. We currently use the adhesion sheets, but the time/effort required to change those out periodically is becoming a pain.
  11. I am looking to get the dimensions of the Ultimaker brand (NFC) filament spools (750g). We are purchasing a UM3 and are planning to get a vacuum sealer to store partial spools of filament, so we want to verify the dimensions to make sure they will fit in the vacuum sealer bags. Thanks in advance.
