So i picked up an X1 carbon off facebook a few weeks ago. Previus owner only printed on it a few times. I printed in PLA and PetG with good results.
The last few prints were Petg.
I had some stringing with Petg HF but i seemed to have cured that with an Auto calibration.
So i went back to Pla for a few prints and i get this.
Bambu basic Pla.
It might be but hard to tell. To do a decent inspection, you have to take the magnetic cover off. Also, I found that this tool is perfect for inspecting the nozzle from underneath.
You want the version that has the rotating lamp so that you can aim the light. I purchased and returned 3 of these because they all have fixed lights which is damned-near useless in my experience. This one pivots the LED so that you can aim it properly onto the nozzle.
These are not easy to find. There are hundreds of BS Chinese vendors spamming Amazon with the same cheap product. They all have two things in common: they don’t have a pivoting lamp, and the battery holder needs to be unscrewed. This model is what you would expect from a proper light—it has a snap-on battery cover with no tools required and no small cover screws to lose when swapping batteries.
