PrusaSlicer 2.8's new features might be quite useful...

[@supercurioTube]

I really like the "Actual volumetric flow rate", it has been particularly helpful to identify quality issues I had with a soft TPU recently.

[@ZappyOh]

What is you max reliable flow for 95A TPU? I'm using 9mm² on a K1max, and that is perhaps a bit low?

[@supercurioTube]

@@ZappyOh the max usable depends quite a bit based which TPU, extruder and nozzle. To give you an idea, with a direct drive (CR-10 V3) and 0.6mm nozzle, I calibrated to: - 12.5 mm³/s on AmazonBasics TPU 95A - 9.6 mm³/s on Overture TPU A few % above that, the extrusion becomes inconsistent then the filament buckles and escapes its path. I'm sure the temperature influences that too but I haven't tested. BTW, the Shore hardness of the TPU seems to be the main factor, I measured - AmazonBasics TPU 95A: 95.5A, 48D - Overture TPU: 89A, 40D - Fiberflex 40D: 94.5A, 38D OrcaSlicer Max Flow Rate works perfectly to evaluate that one. But for quality including on tricky overhangs you might need to go much lower on softer filaments.

The "actual speed" information is also useful for optimizing a design for mass production. If you know where the print is ACTUALLY slowing down, you can make (hopefully) minor changes, to limit the speed lost to acceleration.

[@critter42]

Actually, I would like to see a video on the maths involved where you get into the stuff that you didn't want to get into here. I never realized what exactly jerk was until now

[@dbuezas]

At least in Marlin, jerk doesn't mean acceleration change rate as in physics. It's actually the maximum allowed instantaneous change In speed. Afaik it's the max difference between the end of a velocity trapezoid and the beginning of the next one. Except for E jerk, that one limits printing acceleration when using linear advance (nozzle pressure needs to be achieved instantaneously for now in Marlin. Working on that)

[@ahow8017]

I definitely watch every video like this. I have not been printing as much as I used to. Sometimes I will jump a few versions of the slicer. Then I’m lost relearning for the next few prints. I now use Prusa slicer exclusively because it is the only slicer that is supported by my older Mac. I am not going to replace a fully functional computer that I solely use for backing up my phone and 3D printing. Keep it up.

[@mvadu]

For me these videos are worth watching, eve after reading the release notes I had missed few things you showed here.

[@meanman6992]

Printing to fast or cold can also cause the Matt finish you spoke of, which is also a sign the print will likely have weak layer adhesion and you should raise the hot end print temp or slow down, or a combination there of. Shiny finish tends to equate to a stronger layer to layer bond and stronger part in my experience.

[@tommihommi1]

too much cooling too

[@evanbarnes9984]

I was just thinking about this yesterday, because every print that comes off our Bambu printers at work comes out matte, but every print on our mk4s comes out shiny, even when they both use the same filament. And similarly, the Bambu prints are much more brittle with worse layer adhesion. It's nice to have the option to trade quality for speed since we use these for rapid prototyping, but I think Bambu was too aggressive in their stock tunings. It's impressively fast, but I often need the slower mk4s for strong and dimensionally accurate prints. This is such a fascinating technology!

The menu change is typical of open source folly in UX design. Deviating from basic interface conventions is fine if there's a big upside, and I don't see it. I do see a "we know better" mistake that too many OSS developers make.

[@JoeSchmoe-lq1uo]

One advantage to the new design is the recovery of a bit of screen real estate for the 3d model space. When my laptop is plugged into the huge monitor on my desk it doesn't really matter, but when the slicer is displayed on the laptop's 13" screen every pixel counts.

Hopefully the other improvements really are improvements, but for now the new menu is not an improvement.

[@JustTryGambling]

This will be super useful for diagnosing print artifacts. You can immediately tell if something wrong is due to speed and acceleration and adjust accordingly. All they need now is a thermal capacity mode that tells you how much thermal capacity a specific portion of that print will have and we will be one step closer to perfectly predicting a print’s outcome

[@EscapeAero]

I honestly think the actual speed is going to be pretty useful. Here's why: Layer adhesion is affected by the loss of gloss on the straightaways and long runs. Having a preview like this let's you know in advance what structural benefit you're trading for max speed. Pretty nifty for structural prints!

[@awkwardsaxon9418]

6:50 what changes were made? Reduced top speed or reduced acceleration? Would be cool if you could paint an area you want to have a nice looking surface finish on and the slicer would use that data to make it so. Like how you paint supports

[@JoeSchmoe-lq1uo]

The only setting you really need to change is the max volumetric flow rate in the filament profile. If you run a max volumetric flow rate test (Orca Slicer) you can determine that rate for each of your filaments.

[@suivzmoi]

adaptive pressure advance is coming to orca soon. this will require calibrating PA at different accels and flow rates and letting the model change PA automatically depending on any line's given flow rate. this means any improvement to flow rate display will be welcome.

[@JoeSchmoe-lq1uo]

The best way to deal with this is to run a max volumetric speed test for your filament (Orca Slicer). On that test print you will notice a flow rate at which the finish changes. Set the max volumetric flow for that filament according to the results of the flow test. After that you can set your layer height, extrusion width, accelerations and speeds however you want in the print settings and the slicer will make sure the print speed is capped so as not to exceed the max volumetric flow rate you set in the filament profile. Subsequent prints will not show those artifacts from the vid regardless of acceleration because the volumetric flow rate will not exceed what you put in the filament profile.

[@JoeSchmoe-lq1uo]

Yes, I'd love to see more slow-mo in the videos to catch print errors as they happen. A nice example from this vid is at 3:26 where the 1st layer of solid infill for the deck of the benchy fails to anchor properly and just leaves a sagging loop. My vote is for more slo-mo, but maybe not a 15min continuous play of it. That would be a bit too much like compilation porn ;-)

Yeah, but in the real world of printing objects, the flow rate is dependent on print head acceleration (and velocity) to lay down a consistently shaped bead of plastic.
