  1. Hello all. As a matter of follow up, I have done about 3 more prints, each lasting 12 hours or more…I have used spool slots A, B, and D, in the subsequent prints - each with Ultimaker ABS (the same as before), and the error has not returned. Things seem to be fine as it relates to this odd error. I have seen the behavior other people are reporting with the filament eject buttons being unresponsive, but that seems to be confirmed as a shortcoming of the 5.8.0 firmware (and something I can live with until the next firmware). I am going to go ahead and call t

  3. Thank you. Last question (for now)...does this suggest that, on this firmware, if I can complete a print successfully without the unknown error occurring - perhaps it could be related to the firmware? I do know about the mystery of the 998 error...just curious what to look for after doing this.
  4. Thanks. I will take a look. The print head seem to be secure and in place. I will first try the file @SandervG suggested...then check this. If you are referring to the "Lift switch" calibration...I did that...I also re-installed the 5.8.0 firmware three times...twice over the network (once on wifi and once wired) and the last time using the USB. No luck.
  5. Mine has the robot...I got the S5 close to it's release...only got the air handler and material station a couple days ago. So excited (just hoping to iron these issues out). I will get this file installed as soon as my 4-hour test print is completed. Do I just choose to "upgrade firmware" to install it?
  6. I am so glad I found this thread. I posted a [lengthy] message yesterday describing my issue (with videos). I have all of the same experiences here...can't unload material using the button on the material station or with the touch screen...but I am having a different issue then mentioned above which is an unknown error at the end of every successful print. I get this screen each time and have to reboot the printer manually. I even caught it on video (seen at the end of the video): I would love to know that this may be part of the bugs
  7. Hello all, I just received my air handler and material station a couple days ago. I have printed a few things successfully with Ultimaker ABS…but I can’t get the print to end gracefully. Each time the print ends, I get the following error: At the end of a 14-hour print, I decided to video the end of it to see if it would happen again - and it did. It has happened each time. Here is that video: You will notice that the filament begins to pull back away from the hot end and it stops in the Bowden tube right as the Ultimaker
  8. Ha...sorry. Thought it was obvious. The issue I am referring to is the curving that happened at the top of the print. I definitely know it wasn't the most ideal orientation...my later print came out fine. I was mostly curious if I could print it on the S5. You may have nailed it with the wobble theory.
  9. I have a question about my S5. I tried to print a camera mount for my CR-10 printer. I found the mount on Thingiverse (https://www.thingiverse.com/thing:2916010) and decided to print it using my S5 and Ultimaker ABS filament. I made a few minor modifications to the print settings, such as to extend the brim size, since I wanted to print this standing upright and with good bed adhesion at the bottom. This is how it looked sliced in Cura: The pics below are how it actually printed at the top. For the record, the bed adhesion was so good (and I was mildly impati
  10. I only wonder then, how are the printers of far less quality and price, seem to get the tolerances closer. I have had far fewer issues with both the Prusa and the CR 10. The only answer I can come up with is the software. Before I bought my Ultimakers, I had never used Cura. I still only use Cura for my Ultimakers. I use simplify 3D for the others. Could this be simply be a slicing issue?
  11. Thanks to all here. Very informative post. I do get that the best tolerances can be built for in CAD (and I usually do). Unfortunately, I was having to print a complex part that someone else designed. All I had was an STL, but the print was part of a bigger installation where I needed better accuracy than I was getting with the default profile. The horizon expansion adjustment (to -0.03) allowed me to get the expected tolerances without any other changes. And this was printing with PETG (Polymaker Lite).
  12. Changing Horizon expansion to -0.03 was experience changing for me. This was a magical thread. Thank you. And credit to @gr5 as well. I know he tried to tell me to try -0.025 some time ago, and I did...but I didn't have a part to print that would be so sensitive to spec. This setting just successfully printed a PETG part I have tried 5 times to no avail (only changing flow rate before this).
  13. Definitely interested in tracking these results. I love the quality of my prints on the s5, but the dimensions are seldom what I was expecting. I just started a print with the horizontal expansion of -0.03 in hopes to get a product that fits my application.
