Hi Community I have an Ultimaker Original and I have been using it for 3 years now. The printer can produce very nice prints in PLA, but the printhead (especially the hotend) are a pain. Maintenance is very intense and time consuming. I already changed all belts in the past, and of course I switched to the heated bed. Now, I'm looking for an option to completely change the printhead. The teflon coupler is almost $20 and has to be changed just too often, even though I only print PLA. What options do I have to change the printhead? Basically I just want to red

With PLA there should be no need to use hair spray to increase bed adhesion. If bed levelling is fine and the amount of extrusion as well, adhesion should be fine. If I have trouble, I wash the glass plate with water and soap and then it's fine.

Hi I print a self made cover of a cable duct with PLA with my UMO. Printing basically works fine, but there is one feature I would like to optimize. I think the problem is that the slicing of cura is not ideal for the geometry. See the feature marked in yellow in the attached image. First, I printed without the inner whole in the corner. Since I had overextrusion in that part, i made the whole because i thaught that printing without infill would be possible. But now, the print quality in the corner suffers. Are there advanced settigns in cura to change the way this feat

Lubicration of the filament did the trick! Thanks for this hint. It's printing just fine now!

Retraction is off, infill speed is the same as the walls. When I try the oil, isn't it bad when I print PLA again? Maybe silicon spray would be a better option?

Ok, i will give it a try with an even higher temp and layer height 0.2mm. When I tried printing ninjaflex the first time 2 years a go, I just wanted to try. The results were pretty good, which of course increased the expectations. What I just don't understand is that the walls basically don't suffer from underextrusion but primarily the infill. So, how do you print flex material reliable?

Hi I'm struggling printing Ninjaflex with my Ultimaker Original. I tried printing with the following settings: Nozzle: 0.4mm (3dsolex) Print speed: I tried 10 - 30 mm/s Temp: I tried 230-250°C Bed: 50 °C Layer height: I tried 0.15 and 0.1mm I tried with different values for flow and filament diameter, seems to have no impact at all. I often have underextrusion, especially in the infill. At the moment I try printing a cylinder with D=20mm, H=20mm, so basically a really easy geometry. I print with 100% infill, but it ends being rather 40% bec
