    Printcore Heights

    in UltiMaker 3D printers

    Posted

    Hi and welcome,

    I'm having trouble viewing the pictures.

    Anyway, the whole point of the Ultimaker 3 is having the two cores at different heights so that they don't interfere with the print while they are not being used.

    It prints with the left nozzle with the right nozzle up, then it goes to the side of the printer and switches the nozzle, this brings the right nozzle down (lower than the left nozzle) then it prints with it ... etc...

    It wasn't letting me embed the images, I tried again and it seems to work now.

    The different heights of the print heads was one of the reasons I went with this printer. I just thought that would be more while it was running and the heads would sit normally at the same height. Currently it looks like print head 1 can never get as low as print head 2. Just wanted to see if the tapered parts that they sit in are meant to be different or do I need to send the printer back.

    When you say the printer stopped feeding part way through, which core?

    The unrealistic difference between heights can be because there is a bit of filament poking out. Try to clean the core as much as possible.

    Also, you may have to do a manual leveling to make sure it is within tolerance and then do an active level to make sure.

    There is also a difference in the AA core and BB core in design in that the BB core is designed differently for PVA printing.

    It was printcore 1 that stopped, I wasn't printing with the PVA. But I also pulled out the filament and it looked pretty munched at the feeding point so I think maybe it just got caught on the spool holder or somewhere.

    I did a manual leveling and that's when I started getting this error and when I noticed the difference of where the print cores sit I thought I should check if it wasn't a problem with the printer itself.

    I was aware that there was a difference between the AA and BB cores, but didn't think to swap them over. I will do that when I get home from work

    Hi,

    I got my Ultimaker 3 yesterday but have had a few problems so far. The first print stopped feeding part way through and now I am getting an error saying something along the lines of the height difference between the print cores is not realistic. I've had a look into it and apparently that means the autoleveling is failing.

    However I also noticed the print cores sit at two different heights, even just after installing them. Is this normal? Print Core Heights

    I also noticed that the tapered hole that the print core drops through is more tapered in print head 2 than print head 1. This seems like the sort of thing that should be the same on both.
