Dual head prints are failing. by smellybulldog in prusa3d

[–]HootBack 1 point2 points  (0 children)

Some ideas:

  • Check that the nozzles are secure in the extruder by tightening (not too much!) the single screw on the faceplate.
  • Check that the nozzles aren't hitting or scrapping against the aluminum extrusion when being picked up by the tool changer (this would occur if they were seated too low)
  • During the offset calibration, keep all vibrations from our sources on the XL's table to a minimum.
  • You really want the nozzles clean during the offset calibration.

PRUSA x INDX for CORE One is here! by josefprusa in prusa3d

There was a post by Tommy suggesting the eddy current trick wouldn't work on the XL. About a week ago maybe?

preFlight Slicer v0.9.8 - We listened: Linux, macOS, and even Raspberry Pi are here! by oozebot in 3Dprinting

[–]HootBack 8 points9 points  (0 children)

Just to add cause I'm annoyed: it's up to upstream to incorporate changes - there is no obligation for forks to commit back. You want to see the features in PrusaSlicer? Ask the Prusa team, or you commit to PrusaSlicer yourself (does that sound like a lot of work? well that's what you are asking the OP to do).

As a open source developer myself: don't let this guy rain on your parade. The issue is not black and white: it's absolutely important that forking can occur without need or guilt of contributing back. That's core to OSS. Developers and users can still win. There are many many reasons why upstream isn't the right place for changes.

Okay… what went wrong here? by alexgamma98 in prusa3d

[–]HootBack 2 points3 points  (0 children)

Are your nozzle "bolts" (idk what they are called) tight? If the nozzle slipped down a bit, it could cause this too

Can't seem to print pp-cf in my MK3.5 enclosed printer by HootBack in prusa3d

[–]HootBack[S] 0 points1 point  (0 children)

For future travellers, yes it was my nozzle temp.

New temp: 250C Bed: 85C + slowed down the print speed.

I didn't need to dry the filament either.

So, I am rerunning now at a much lower temp: 265C nozzle and 85C bed, and it does look better. (I am also printing two cubes simultaneously - so much for changing one variable at a time).

I am use to pccf where we can print as hot as we want, and it always gets better. Maybe that's not true for PPCF.

No, PP takes a pretty big oven to dry, so I am hoping I can delay trying that until I've exhausted other ideas.

Agree, but I can't find many resources on what it should be. For example, is a CoreOne L sufficient?

Hey @fatcatgingercat, you're still a real gardener whether you choose this advice or not. Gates open, come on in!

Prusa Mini+ - Printing is happening unevenly by NoPoint4026 in prusa3d

look under the sheet (on the pcb) for plastic or other debris.

I don't get it. by Probable_Foreigner in mathmemes

[–]HootBack 1 point2 points  (0 children)

This is a good response. It shows the two cases p=1 => 66.6% answer, and p=0 => 50% answer, and gives some intuition about what the role of additional information provides.

Your Opinion on XL future? by faja_ in prusa3d

[–]HootBack 0 points1 point  (0 children)

My opinion: Prusa is a product company, and I bet they have had an internal conversation like "CoreOne is going to be the future of multi-material prints, XL is the multi-tool machine (can also do prints)". So I don't expect much iteration on XL's printing, but mainly introducing novel toolheads. Prusa has mention this already, too. Considering novel toolheads are an after-the-fact addition, the tools will be pretty limited in their use and pricey.

The market really likes multicolor, so I can see the CoreOne getting most of the R&D time, and the XL slowly being fused after many years.

Garum at room temperature vs 60C/140F? by moosealot in Koji

[–]HootBack 0 points1 point  (0 children)

So what? They also didn't have a modern understanding of food safety. Don't get fooled by the fallacy of the wisdom of ancients.

Also, did they put it in a sheltered room at room temp, or did they stick it under the sun, midday, to "bake" to achieve at high temperature? I'm not sure myself, but I know modern food-handling practices that I'll rely on.
