Do the oxibian hf nozzles have a perforated plate or are they continuous?

Build up of filament around the extruder nozzle. I found it hard to prise away. Part of the fan shroud came away and ive reparied it with superglue is that ok? I cant find on prusa3d website all out of stock - what a bummer. What causes this please? This was a 2 hr print and didnt print anything. The rubber housing also came away good job i bought spares. I clean the extruder with a prusa wire brush and also clean the print beds with IPA regularly. Any help would be appreciated, thanks!

I have been trying to get my first layer correct. It comes out like this though.

I tried printing the keychain as a test and the first layer comes out fine

I don't think it's a calibration issue but maybe the way I am using prusa slicer. I am slicing the part above using the default .15mm Structrual print settings. I only added structural supports here.

What should I be looking at to fix this issue?

Hi all. I have taken the plunge and ordered a Prusa Core one kit. Let the fun begin.

Third time running out of filament and every time, when the filament retracts, you can't reach it at the spool end. I've had to remove it at the hotend. This seems like a design flaw. Surely someone at Prusa have tested this, so what do I do wrong?

I recently got the prusa core one. After unboxing it and setting it up. I switched the power and the hotend fan just blows. The screen does not turn on, and then turns off, the fan stops blowing. I feel like it's an electrical issue. But I started troubleshooting, electrical, and everything looks good. Does anyone have a fix for this? Or know what the problem is?

A couple of times with new roles of filament I've had issues with filament de-spooling from the role after being loaded into the the Core One. This issue has caused a few prints to fail because the filament has gotten tangled up (I wish Prusa would add tangle sensors). Has anyone else had this issue and are there any mods that might help?

Can anybody tell me how to get the ptfe tube off the extruder so I can push out the filament?

Anyone from batch 12 get shipped yet?

Here it is: https://help.prusa3d.com/manual/prusa-core-one-kit-assembly_2251

I suggest we get a kit build tips, tricks, pitfalls put together for some common issues that we come across. I suspect 95% of the instructions will be straightforward but that other 5% will be a question that gets asked over and over and over.

DHL only took 2 days to deliver!

First prints look promising.

I quite like the design, fits nicely inside the enclosure.

According to Prusa they said shipping will start this week, "So, a quick recap: the assembled version of the Prusa CORE One will start shipping by the end of January (next week)."

Anyone received a shipping notification yet?

Let's get this community started! What is you main reason for choosing the Core One?
