[powden tube pop out during print.]

This happened to me some time ago, and I don't remember if I got the solution from here or from 'another network', but the issue was that the fitting that holds the tube into the feeder was defective, as in had a weak grip.

 

I ordered a supply of replacements (third party) and popped one in and it has not happened since.

Thanks, which third party product did you get?

Hi, I have been printing with PVA and PLA and the powden tube popped out during the last print. Luckily the print didn't fail completely. But how can I stop this from happening?

[cura slicing make curved bottom flat]

Hello

I am trying to print this 3d vaulted arch model in cura but as soon as I slice the model the curvy bottom part  of my model become flat. I tried to load the same model into prusa slicer and it turns out to be fine. However, I want to print this model with my ultimaker. So what could be the cause of this?

I have attached some screenshot and the cura file below.

Thanks

[Blocked pva nozzle]

Thanks guys . Sorry for the late reply. But I managed to dissemble the print core and cleared the blockage.

[Blocked pva nozzle]

Hi guys,

 

I have an Ultimaker  3 extend here and after a couple failed print with dual extrutions, the BB0.4 nozzle is blocked by the botched up PVAs and I cannot flush out the block with hot pull even after multiple attempts. Here are the photos showing how far the cleaning fillament will go in marked with a black marker. Any chance I can unblock the nozzle? thanks

And your first fail seems to happen due to the material not sticking to the build plate. Which material are you printing with? With most materials it is recommended to use an adhesive like a glue stick. Also make sure your build plate is clean before you start (no dust and no grease). The second fail seems to have happened because of under extrusion. Make sure your feeder at the back is at the right tension, there is a indicator on the side. It should be in the middle. 

It could also be that the feeder has not been cleaned in a long time and needs to be cleaned. There is a bolt with teeth in there, pushing the filament upwards. If there is a lot of residue in between those teeth it can not grip well and will give under extrusion as a result. Here are some resources on how to clean them: https://ultimaker.com/en/resources/52504-clean-the-feeders

In addition, I think both of our feeder are broken. I have spoken with my colleague and there has been previous attempt to open up the feeder but the guy who worked here before might have broken something. And  tension adjustment   on both feeders aren't working. Where can we order replacement feeder parts? We are based in the UK

Hi thanks, I checked the feeder and it is a bit dirty . There are some deep marks on the filament and I think the tension indicator has snapped off. Here are the pics below

Not sure if it is just the photo, but your front belt seems a bit too loose. Please check if the tension is ok and if not, check which pulley is loose and tighten the set screw.

Thank yes the front belt does seem to be a bit loose. But how can I fasten it?

Hi guys, 

I started a job at a university and we have a ultimaker 3. We are trying to print this piece for our project but it kept failing. I have attached some images below. First the print turned into a spaghetti ball while using dual extrusion with pva support. Because it's kind of urgent so we thought it might be easier to print with a single extruder. However, it didn't work either, the print start becoming stringy. 

 

And we need this piece for  project next week. Please help!!
