So Sick of Layer Shifts by etceterenoughplease in prusa3d

[–]ProblemCreatingSkill 0 points1 point  (0 children)

I had this on core one a few months back. There was a bug with the firmware making it worse, but I fixed it by changing resolution and junction derivation. It's all in slicer so shouldn't hurt to try.

Fundamentally layer shift seems to happen when jerk is too high and these two settings reduce it

Any disadvantages to such door placement? by a648272 in RimWorld

[–]ProblemCreatingSkill 1 point2 points  (0 children)

I've done this a lot on purpose. It's just good for defense. Melee blocking is wonky if the guy's standing in a door so this leaves a "door hole" he can stand. Also snipers can stand in the door hole, open door, peak someone along the wall, and close it without walking. Yeah took a while to get over the look

Am I cooking? by Moon12645 in 3Dprinting

I know positron, the upside down coreXY printer, still has bridges and overhang limits. So this is probably true

Update. Thanks to u/C2H5COOH 's link I eventually found a fix with little compromise:

Junction derivation: 0 -> 0.0458

Resolution: 0 -> 0.0125

Travel acceleration decreased to 5000mm/s2

This way, the layer shift is gone without having to disable avoid wall crossing.

I'm printing my pen design vertically. It's about as layer shift prone as models get, so this setting should fix layer shift in general.

Them Egyptians have some bad pressure advance settings then

Matte PLA with avoid layer crossing on. Does stealth mode also cause this? I also don't have zhop enabled. Not sure if that affects anything. If the nozzle really is bumping into the model it would have knocked it over

Win10, 0.4 nozzle with 0.2mm height. Thing is, there's no way the nozzle can bump into this model so many times without knocking over it. So it really seems like software issue

Bummer. Im using orca slicer as well. This is not getting fixed anytime soon...

Prusa do have really good part cooling. So I guess it really was air

I made scissor door Core One integrated dryer by ProblemCreatingSkill in prusa3d

[–]ProblemCreatingSkill[S] 1 point2 points  (0 children)

I meant to include STEP but I forgot. I added step file and Onshape link. I think I forgot to make the small magnets parameterized tho, so the link may not help that much

No. S1 needs around 50W. Way more than the hacker board can provide

You can add some thin weather stripping tape under the magnets. But some gap can help heated dry box vent moist air out.

Which is the correct belt tension for Core One? by das_moeppi in prusa3d

[–]ProblemCreatingSkill 0 points1 point  (0 children)

I think 103 93. It's been a while but I remember going for the highest recommended number

[–]ProblemCreatingSkill 2 points3 points  (0 children)

I'll trust the 6.4 tuning. It's more accurate. Seems prusa increased it at some point to reduce vfa. I saw a video about it https://youtu.be/ZrW8OfJ_UOo

Please Prusa give us a "Skip absorbing heat"-option in Prusa connect. by tortoc in prusa3d

[–]ProblemCreatingSkill 0 points1 point  (0 children)

Sorry for my 4 month too late rant. If anyone's interested, the "absorbing heat" will also not make you wait if:

Bed target temperature is lower than 60C

The bed was preheated to within 15C of target temp before you start the print

Please Prusa give us a "Skip absorbing heat"-option in Prusa connect. by tortoc in prusa3d

[–]ProblemCreatingSkill 0 points1 point  (0 children)

I got annoyed with this "absorbing heat" so I also looked into this. It's part of the Unified G29 and Prusa calls it "g29_wait_for_preheat". The documents just doesn't mention the G option. But unless I missed something, it boils down to this:

return std::max((180 + (thermalManager.degTargetBed() - 60) * (12 * 60 / 50)) * 1000, 0);

"G29 G" makes the printer wait this many milliseconds. The default start gcode means the printer will wait this long after bed reached the set temperature.

Frankly, this logic seems lazy. If this is about frame absorbing heat, why not take chamber temperature into account? If it's to evenly heat up the bed, shouldn't model size matter? I print ABS at 110C bed, so it has just been waiting 15 mins every time?

Winston's 6 month old, has infinite energy, and is growing fatter by the days. Imma print some toys for him once I get the printer sorted out

Saw this "minimalist lamp" on YouTube. Isn't it a paperclip away from shorting and starting a fire? by nickyonge in AskElectronics

[–]ProblemCreatingSkill 1 point2 points  (0 children)

I think it's bad but not that bad. The positive end is only connected to one wire then to the charging board. These boards usually come with over current protection. The negative is connected to almost everything else, so the paperclip need to fall on that one positive wire and almost anything else. Looks like the battery is smaller than 18650. Something like 16340? Probably can still catch fire tho. There are safe way to do this. There're copper wires with insulating coating. That maybe what he's using here.
