  1. I don't think so, since the firmware doesn't expect there to be an air manager, and the air manager is controlled through the firmware and slicing of the files (for max build chamber volume). There are some third party S3 enclosures out there with built in fans.

    Wow, I didn't run past this information before. It seems, that it is actually the front fan, that is causing the problem. Thats a connection, I'd have never made on my own. Thank you so much. A replacement part is already on the way.

     

    The fan thing took a bit to diagnose as a potential cause for the issue when we first came across it--but the good news is, it's one of the easiest things to test for and definitively rule out ones you are looking for it.

  3. @capcotechuser are you sure about the bed temperature? 215C is about 100 degrees too high for the bed. What model Ultimaker are you printing on?

    Are the sliding blocks on your machine black or white? If it's an older machine with black plastic blocks, those machines didn't come with any enclosures and the blocks are made of ABS, so they will take wear and tear from heat if you enclose the machine and don't leave some avenue for excess heat to escape. The blocks (especially on your Y axis) spend a lot of time close to the bed during your first few layers.

    For the later machines (S3, Connect, etc), the blocks are made of a different material--it's more heat resistant. However, the enclosures Ultimaker makes for those machines are also designed to control the ambient temperature and keep it from overheating. I think max recommended build chamber temperature is around 55C.

    Hi Erin.  Thank you for this information.

    I guess I hastily purchased a used UM2 not realizing it was obsolete and not (easily) supported.

     

    The Ultimaker 2 was produced from 2013 to 2015. It's a pretty solid machine, but the UM2+ had some really great improvements. If you put an extrusion upgrade kit on the UM2 it  changes out the entire extrusion path for an Ultimaker 2+ one (which makes it more compatible for easily available parts) and just grants you a lot more reliability with the geared feeder instead of the knurled sleeve on the UM2 feeder.

  5. @cav it's exactly what @gr5 said. All the Print Cores go through physical checks as well as functional tests (including printing with it) at the factory before they ship. A little residual filament in the Print Core is definitely normal. The Print Cores are tested with PLA, so anything that's still in the Print Core will purge out the first time you print with it.

    Is there a reason I can't find anything about the Ultimaker 2 on here? Has it been discontinued? I updated the Cura on my machine and now I can't find where the different extruder selections are for the Olsen block upgrade. Can anyone assist me with this please?

     

    Thanking you in advance.

    The UM2 was built until 2015. Starting in 2016 the UM2+ was released...and now we have the Ultimaker 2+ Connect.

    If you need an earlier version of Cura, you can go back to a previous version: https://github.com/Ultimaker/Cura/tags

    However, Ultimaker 4.9.1 does still have the ability to let you pick an Ultimaker 2 with an Olsson block upgrade so you can set for different nozzle sizes.

  7. @kupfeli the bed isn't intended for printing below 60C as far as I am aware. @Szahari can explain in more detail.

    I have found a work around: by starting a print with the temperature at 60 C, aborting it, and then starting your lower temperature print while the bed is still warm.

     

    What are you printing that needs to be done at below 60 bed temperature? I usually find 60C to be a great starting point.

  8. What model printer are you using?


    For most Ultimaker printers the hot end cooling fan turns on when your nozzle or Print Core heat to 50C. It cannot be controlled in the settings.


    For your model cooling fans--how long are you waiting for those to turn on? They don't kick on until the second or third layer, in order to prevent adhesion issues.
