2 days after I assembled my XL/5, I have some small issues...

I am happy my XL/5 has arrived, and I built it 2 days ago. All together it prints, but...

I have some questions/issues:

  1. The primary  purge lines in the front of the printbed are printed on the tabs, but partly next to themn, in the open air. So I have purgelines that are drooping down. Is this by design?
  2. Severe stringing. This is with the default settings in 2.6.1 for generic PLA (DasFilament PLA in this case). I understand that some stringing is there due to the larger nozzle, but this is a 'bit' too excessive, I think. Ambient temperature 24-26°C, Humidity ~35%, filament was open for several weeks in this environment.
    I am not looking forward to drying every filament before each print...
  3. I switch off the power during night (until I found a way to switch off the lights by some command/function) when it's not printing. I use a switched socket, so it is the same as the power switch at the back. But twice I got a BlueScreen when I powered it up in the morning. After a press on the reset button it starts up normally. Any idea?
  4. I am currently printing my first self-sliced multi-color model: a dual-colored benchy. It is visible (more or less 🙂 ) in the first pic. Sometimes, the printer pauses for 10-15 seconds between tool changes. Any idea why this is?
  5. The benchy is done. Aftzer I removed most of the stringing, I noticed two very different surface textures. The part of the hull where there were no color changes per layer is printing perfect. The part of the huill where there are color changes, looks almost like a 'fuzzy' print. Ho can I solve this?

Sorry for the long (first) post... 🙂

Thanks for giving me some advice!

Hi, I suggest you read this tread. It provides the best guidance on things to check/try.

I think you've answered your benchy problem

  I am not looking forward to drying every filament before each print...

It's already necessary for (most of) us to dry filament for every print, by buying a five headed machine you commited yourself to five times as much drying.

Before doing anything drastic dry both those filaments properly and print again - let's see how much stringing is machine based and how much due to the filament.

Cheerio,

I'm pretty sure its not a humid PLA problem XD
I have never dried any of my ~50kg PLA yet in my past 8 years or so.

@ardjan, take a look at this guide that adds "G1 Y360 E-1 F24000" on the End G-code of filament profiles.

As for Issue #1

I quite like it. It gives you less (sometimes strongly) attached purge lines to remove, and it even has a starting handle to get it off. So I think this is by design.

#3
I have noticed this too. I think it has to do with the slicer wrongly thinking an extruder is not going to get used for an extended amount of time, and starts cooling it 110C lower. But then needs to come in action again before it had time to heat up and stabilize again. Some layer changes I see this happening, and some other not, and I'm not sure yet what causes this to happen. But I'm pretty sure this will be fixed soon.

Thanks! I will take a look and try it.

#1 I now get used to it. It doesn't droop to to the floor/bottom of the printer; as long as that doesn't happen, it's ok with me.

#4 (I guess you meant that) I have connected a Raspi4 with Octoprint yesterday, and can now see what's going on: it sets the non-used nozzles to 70°C, and starts heating them up before they are needed again. Usually, they heat up right on time and it can do the tool change immediately. I think in the beginning it needed to learn how long the heating would take. At least, I haven't seen the issue anymore since yetserday.

Dry it first and we'll see what's left to deal with.

I have never dried any of my ~50kg PLA yet in my past 8 years or so.

Maybe you should try it.

Cheerio,

I was also in Team Never Dry but that's because where I live humidity is around 35% in summer and not much better in winter. It's basically impossible to have wet filament unless I put it in the bathtub. But I recently had to change my tune when printing TPU. I now have a filament dryer and it makes a huge difference.

I've noticed that humidity in filament has quite an impact on the XL. Even brand-new filament has stringing on the XL that gets fixed after I let it sit overnight in the dryer.

I printed a benchy on the XL that showed stringing, then printed it on the Mini right after with the same filament and it was flawless. Then I dried it overnight and now it printed flawlessly with the same gcode on the XL. I don't get it.

Even PLA shows that behaviour. I never had to dry my PLA before, only the PETG.
