Why not both

Was it in “Ubik” that people had to pay a fee every time they wanted to use their domestic appliances or even open the door to their own house?

Not one in particular, just the first thing that came to mind since I use it a lot on linux. I even use NewPipe on android, didn’t even remember it had an option to download

yt-dlp inside termux?

Baikal works wonders

Nah 85/90 degrees is perfect for the job. Much better and more uniform than a heatgun, let alone a hairdryer

Is that a motorola moto z2 play? I owned that phone and I used to disassemble it just like this!

Edit: saw in another comment that it’s a z4. The camera did look strange for a z2 at a second glance

While I don’t remember his name, I remember there was a Darknet Diaries episode about the researcher who first investigated the problem. The episode was very thorough, I liked it a lot. I also don’t remember the name of the episode, so I guess this comment is kinda useless

I second this

Also dumbest idea, have you tried a brand new spool of PLA? Just to exclude an incredibly wet filament. Because that can cause all sorts of problems

Hello, I suggested heat creep in your last post, which didn’t end up being the issue. I don’t remember if anyone suggested it, but have you tried checking the bowden assembly, on the motor side? Whether the stepper works, or the gears wore down (I’m pointing towards this), or there are clogs somewhere in the mechanism, even some dust that accumulated where it shouldn’t had. Or did you change settings like the current limit on the steppers? If that’s controlled with a potentiometer on the main board, maybe it got turned down for some reason (if so, I’d try to understand why’s that). I don’t know how Klipper handles motor drivers where current limits are controlled in software, I know that Marlin has a dedicated submenu in the Configuration>Advanced Configuration. If you reflashed the firmware, maybe the settings where in the eeprom and did not get transfered over or got overwritten in the flashing process.

I remembered that on a couple different printers I had the same problem as you, and it came down to damaged/untightened nozzles (which you excluded already) or wore down gears or, on the printer I’m working on right now, too low current limits which made the stepper skip steps somewhat randomly

That’s exactly how I wpuld test heat creep. Maybe that’s not it

Since you’ve already excluded a damaged nozzle and other parts, I’m gonna suggest heatcreep.

Maybe the extruder fan broke, so heat creeping up the extruder and melting the filament before it should?

The lid of the pot. Keeping the pot covered makes the water boil quicker

I did that some time ago. I just put the letter in an envelope, with just the receiver address on it, went to my local post office, paid for the service and the stamps, left them the letter and I was done.

I also just saw how they places their vbat and gnd on your main chip, I don’t think I would put any there either unless it asks for it.

What are you exactly saying here? You wouldn’t put vias behind those pads?

Just saw your comment on the PCB size. In that case I would definitely go with a four layer board to avoid issues (heat and signal integrity).

Yep, I’ve also done some tests with ground planes on both layers, and it comes out sparse to say the least. Problem is, I have never made a 4-layer board, do you have any resources on those I can learn from? Are there any particular things to pay attention to? How do I “organize” layers? Which ones do I use for traces and which ones for power planes?

If you have pics of the schematic, I can take a deeper look at it. Cool project, first time I see that chip.

Here’s a quick screenshot, in the original post I linked the git repo which includes all kicad files. It’s rough atm, I haven’t made it look good yet

0.8mm (size) / 0.4mm (hole) vias

Trace width depends on the net class, I calculated them using kicad’s built-in calculator

• 0.127mm (minimum by jlcpcb) for signals and low current
• 0.15mm for motors (the max. current the driver can source is 400mA per channel, I overspec’ed them since my motors will absorb current in the order of 100mA)
• 0.3mm for power supply

I also need that the PCB stays as small as possibile, so having components on both sides is a necessity for me

What do you use now?

My dad has an ender 3 which occasionally does this. I haven’t been able to find anything regarding the problem. Could you elaborate on this hot end fix?

Is this it? https://www.thingiverse.com/thing:3203831
