It’s not that they melt as much as they just keep dumping heat into the heater cartridge and wires.
And if failed in an on state thermal runaway isn’t going to stop it.
It’s relatively rare though. I’m not too worried about it but it’s one of the reasons I watch my printer and of course there’s thermal fuses for such occasions if you really needed it.

The only other thing to worry about are mosfets failing in an ON state.
Not sure if it’s the same risk with SSR’s

Wiring from the PSU to the board?
Or any kind of backfeed on the motors like when you move them by hand quickly? Which I’ve done and not, so far, fried anything but it can.
Man… Gremlins suck.

Ahh. Maybe some internal resistor was causing noise on the pin… or even the MCU.
Like trying to debug a pc issue only to find out it’s a faulty motherboard

How’s the printer doing? Has the Gremlin moved out yet?

I assume they’re past some operational limit. But as long as you have redundancy that’s a risk I’d take for the capacity
- Comment on Resin Printing: Good for a Beginner with Limited Space? 1 week ago:
I will say for ABS this can be mitigated with the following:
- An enclosure (I use a comgrow grow tent)
- Not opening the printer enclosure for at least 20 minutes (so the airborne particulates settle down)
- A replaceable carbon filter (I built a Nevermore duo and bought some activated Charcoal to refill it with)
After doing the above I don’t smell fumes at all. In fact I run the Nevermore even with PLA just to capture any micro particles since the charcoal is easy enough to replace.

Except this bypasses that I believe.

Keeping in mind that may mean that somebody like a cellular provider could do so. Since your local network in that context would be them.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 week ago:
Basically and then that only makes sense if the company’s going to foot the bill. Otherwise they could just make it very very clear that by using extended mode they’re reducing the lifetime of the battery and doing so at their own risk, yadda yadda.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 week ago:
Honestly it makes sense if it pushes the batteries out of the optimal (say 40-80%) charge level.
E.g. it wears out the battery faster.
But if, and only if, you’re getting an extension on the warranty where Tesla is eating the cost of the replacements.

Oh yeah. That makes sense

At least in the space odyssey series they had a weird kind of explanation for that approach. Unlike in Independence Day
- Comment on All cheap smartphones have a fingerprint sensor but all laptops dont have one. Why? 2 weeks ago:
Right. Fingerprint is something you are. Can’t be changed. Same for any biometric.
Useful as one part of a multiple factor authentication at best but never on its own. Not to mention there are cases in the US where you can be compelled, forcibly if needed, to unlock a phone. But compelling you to “say” what your password may be covered under fifth amendment protections.

No problem. I have a script that automates generating the title and link to a video when sharing automatically.
I should look into having it do the same for pipe

I found that pretty handy. Came across it looking for a Numberphile video on the subject. I was pretty sure I’d seen one before but didn’t have a lot of luck finding it.

- Comment on 2mm thick layers on a trophy cup 2 weeks ago:
A little but nothing too fancy. Probably just make it hard to get consistent line widths.
Closest analogy is a hot glue gun. Unless you’re lifting up as you extrude to make a “dab” it’s just going to smear as it moves sideways
- Comment on 2mm thick layers on a trophy cup 2 weeks ago:
Extrusion is a mix of temperature, feed rate, speed and pressure.
Basically the hotend temp could be high enough that the plastic melts but it still “pushes” just fast enough to build pressure to drive it. Not too much, otherwise the filament grinds and extruder skips, but at the right amount you can keep up with the feed.
The nozzle, lifted up a bit, moves slow enough that the filament comes out and spreads out from the pressure pushing on it. Making the line wide and tall.
The dance is keeping those in sync. Move too fast and the lines are thin, too slow and they’re too wide.
Nozzle too high and it doesn’t blend into the layer below as much as sit on top. Too low and the extra pressure pushes the filament around and it curls back up onto the nozzle.

- Comment on 2mm thick layers on a trophy cup 2 weeks ago:
As odd as it sounds, as long as you can feed enough filament into the melt zone faster than it can come out the nozzle you can make larger widths and heights than the actual filament width itself. It’s technically just packing it in.
I can only imagine how hard it had to be to tune the retraction though

Have you updated Klipper itself on your mcu?
In fact what’s the firmware version before you do if you haven’t.
It may be a big fixed by a firmware update but if not as much work as you’ve done with capturing details would probably be handy for Kevin in tracking down a weird bug/issue.
- Comment on Are filament vacuum bags worthwhile? 3 weeks ago:
They have some that change colors letting you know when it’s time but it’s months. Especially if you’re in a dry climate
- Comment on Are filament vacuum bags worthwhile? 3 weeks ago:
For PETG and TPU absolutely, for ABS, probably.
For PLA it’s alright. I live in a high humidity area and so PLA left out for a few weeks tends to get brittle or have issues. But in reality even then it’s generally ok depending on the brand.
All that is to say if you live in a high humidity area get a filament dryer (or make one) and maybe a big thing of desiccant beads.
Put those in a tub and dump your filament in there and you’re probably good to go.
I put filament in my dryer and run the filament via PTFE tube to my printer.
So new filament goes in there and dries for a few hours before I print with it.
Anything I’m printing with goes in the dryer out of the tub and is usually fine but if it’s been sitting there for a few days or it’s going to rain I run the dryer.
But if its hygroscopic like PETG, etc it goes from a bag into the dryer, the dryer’s run while it’s in there and then back into the bag (along with a small canister of gel beads)
The vacuum isn’t so much of a deal as long as there’s somewhere for the moisture to go hence the dessicant beads.
- Comment on Modernizing the best Woodworking Joint to use for 3D Printing 3 weeks ago:
I was wondering about that. Considering with ABS a little acetone makes a stronger overall part.
I was thinking maybe the dovetail would be good in that situation for strength but maybe something like a biscuit or peg and hole as mentioned is better?

Hot end fan. E.g. blowing over the fins on the heat break

One thing that could help with your testing is some way to hand feed it while having the cool ing on the heartbreak. To ensure that only the melt zone has melted plastic.
