SOLVED New to the UM3 world

[Ziogianni84 3]

Hi guys I have recently bought an UM3, loading the PLA and PVA spools included in the box. I manually levelled the bed, then I installed the ultimaker app for android and started printing the UM robot as test print.

Actually It's messing with PVA, there're blobs of material all over the bed surface and there's no trace of a prime tower.

What's wrong with it?

Hi,

If you have no experience in 3d printing i would advise to first try single prints with PLA.

Regarding your issue, wild guess would be that the print bed is to low, did you do the active levelling? Also, i would advise to use Cura instead of the phone app because it's limited in features.

Hi, thanks for your reply. I'm trying active levelling but it doesn't work since the UM says there's a non-realistic difference in height of both printcores. Indeed I see that on the right side while performing the levelling the second printcore doesn't touch the bed glass. It has been a while I'm trying manual levelling to fix the active one but no way!

I have solved the issue related to the active levelling eventually, which I wasn't able to make it work. This maybe will be helpful for new UM users not habituated to auto-levelling procedures, before starting these few steps you need to keep in mind that the distance between the heatbed and its aluminum support underneath doesn't have to exceed 14mm otherwise it won't work! Rule of thumb: tighten up the three bed screws all the way down then start the manual levelling and slowly loosen them in order to calibrate the noozle with the glass plate. At the end of this procedure you can go ahead with active levelling, hope it helps.
