Hello there,
I work at a school and we recently replaced our 1.75mm student run printers with two Ultimaker 2+. In the week or so we have had them we have done fairly extensive testing on our Cura profiles and just trying to get successful prints out of them so we know how to teach the students how to use them.
Unfortunately, in our short time of testing so far, almost every print we send is failing in the first few layers. It fails in several ways, usually because the print does not adhere to the bed and collides with the extruder as it passes back over that area. We are not sure if this is a leveling issue or a bed adherence issue or an extrusion issue, so any help would be appreciated.
So far we have tried blue tape on the platform, lowering the initial layer print speed, printing with skirts and brims, and even changing the extruder temperature to see if it was under extruding. So far none of this has seemed to make a difference. Any help would be appreciated.
Thanks
