    Using BB core for AA core and vice versa

    Thanks again @sandervg for all the help.

    Using BB core for AA core and vice versa

    We ordered some new print cores, but were able to get the old ones working. The main issue was here, you can check out the whole thread. https://ultimaker.com/en/community/37150-um3-pausing-between-layers-homing-to-back-right-and-staying-there-until-user-interaction?page=1&sort=#reply-170770
  3. Thanks for all the help everyone. Great diagnosis's. With the silicon parts I was able to get back to printing. One question left is does this look right? It seems to be hanging down a little bit over the nozzles.

    UM3 Menuing

    I totally agree with this, seems like I waste a lot more time on the UM3 than I do on my UM2. A lot of this has to do with the print cores. They are heating up/cooling down all the time and it takes forever. I noticed I can't even abort a print and restart it without waiting a couple minutes. All that time adds up, but honestly I think it's probably so that people who don't know what they are doing will have less of a time troubleshooting the machine.
  5. It does NOT look like that OMG!?!?!?! I don't ever remember that being in our printer.
  6. So I did some testing. I have a hunch that the issue is when both of the hot ends are at 200 and 215. That's when the AA core doesn't heatup. it will stay around 197 and 213 respectively. I did try your fix and that sometimes made it instantly begin the next later, and sometimes not. It still stopped during the next layer. Do you think it's the print? Can you guys point me to some good test prints for PLA and PVA? Here is a pic of the temperature.html page. Is the bed power supposed to be fluctuating that much?
  7. I would like to note that I can print just PLA core only no problem.
  8. @tomnagel still not sure what you are speaking about, so I'm posting a few photos I took. @daid Heated AA core to 240, printout said 240. Maybe only problem when power is going to both cores?
  9. @tomnagel I think you nailed it. It was doing the first layer then sitting in that corner until I came back ~1 hour later. The other day we had a massive print fail where PLA got stuck over the entire outside of the cover and when it got cleaned up we must have lost the o'ring on the BB core. What kind of o'ring is this? I don't see any mention of it. Could you ship us a new one? I have emailed you the logs.

    Thanks for the video! Managed to get it apart before watching it, but great info.
  11. Here is the gcode I exported https://gist.github.com/shawnkirsch/0c531832763d6ff165ee7ebaa91f84ae
  12. I should also note that the machine isn't technically in the "paused" state. I actually have to hit the pause button, then unpause it. It just won't actually continue printing.
  13. Not sure what is going on. Finally got the printer printing with PVA and PLA. Now for some reason between layers the machine is homing to the back right and staying there until I press "pause" then "unpause." Then it will do another layer and do the same thing. This is happening between each layer that I print with both PVA and PLA. Printing with PLA works just fine. I printed 3DBenchy in just PLA without any issues. I don't have any plugins enabled. I will post the GCode to see if there are any issues there. I can also get logs off the machine. Has anyone seen this behavior? I also rebooted machine to see but it's still the same. Using default profiles on CURA 2_4(beta) and the 2_3_1(released) app. Both have same issue. I will take some video of this today.

    I should have taken a picture of it for you. There was no way that I was going to get all that stuff out of the nozzle. I could have hot pulled for days. It was golden burned. I think we have a bug in our machine. Posting another thread that will explain, but for some reason I think what is happening is that machine is getting confused homing itself to the back right (when looking at machine) and sitting there with the heat on. I think this caused it to burn up and get super clogged. We are using Cura. I have tried the new 2.4 beta and the 2_3 version. I also upgraded the FW on the machine to the most recent stable version. I'm using default printing profiles and ultimaker PVA and matter hackers PLA. Haven't had any issue with the PLA yet.
