  • It's kinda mindblowing what we nowadays consider a print of unacceptable quality, which few years ago was just straight up amazing quality. To get a print looking alright close up was impossible to get without hours of sanding and painting.

    • Right? I know that the pursuit of perfection is a thing, but even a short 5 years ago to get a decent-looking print in less than 10 hours and (after spending hours fiddling with settings) would have been a grail. Nowadays printers out all sorts of amazing things requiring very little work. So, logically, we complain it's not quite good yet :)

    • I still have my wooden Replicator Dual from 2012 🥰 A bunch of my own custom designs to fix flaws in the machine, prints incredibly nice. Arguably on par with my new machines. And I'm thinking about klipperising it, as it's actually supported 😈 that old 8-bit board limits printing to 45mms on fine movements or prints up to 160mms if I lower the print resolution enough to prevent buffer issues. I've rarely used it in the last two years, but I'm really thinking of modernizing it for good dual material use. With a bump cutter like on the Bambu machines. Edit: One thing that completely changes the machine to make it's frame incredibly better was to add washers to all the screws. But also a small amount of impact resistant super glue (or thin epoxy to soak in) to where the washers mount to strengthen the wood.

  • It's really a testament to Prusa that their old printers are still good printers. My mk2 is still working. Sure, it's got the extruder and heatbed of a mk3, and has had the belts and half the moving cables replaced, but it's good enough that I hesitated to jump to the mk4. And I was wondering if the bandages were bike injuries. Both hands at once, light bandages...I hope your face gets better too; swift healing, and thank goodness there's no worse injuries.

  • Hey, TY for making such a comprehensive video! I would like to add that "quality" does not nessearly mean bad or good. I am running a MINI with the IS firmware, and for me, the quality is is just fine. The reduced print-time is way more important to me, than the finish. To be honest, I only noticed it once so far. The surface finish is not great, but since I only print functional parts, looks is not in my requirements. The dimentional tolerances are good and I had no failed prints so far. Thats all I care about!

  • The real killer feature for me was that the Mini/+ now has full PrusaLink, not the weedy barely usable interface it had before. It's great to be able to just print straight from the slicer and watch the progress from a web browser or HomeAssistant plugin. Honestly that to me is more useful than the input shaping.

Even the ender 2 pro can have input shaping with some small edits.

Some static pictures with a side by side comparison. I absolutely trust what you are seeing, but I don't know what exactly you are looking at when you say something isn't quite right. The models are constantly moving, probably to catch the light differently, but I just don't see what is wrong with some of the poorer Input Shaping models...I can't tell what you are looking at. If you had some static pictures with circles or arrows, then I could see what you are seeing and understand a bit better. Keep up the great work.

  • Excellent channel, very good information and analysis. I am from Argentina, unfortunately the recurring crises make it very difficult to have a fleet of printers updated, in the case of our only mini (original, but with a mod on the extruder and barrel) the alpha version with input shappe practically revived it, the speeds and The quality is excellent and the difference with the impressions you got is quite obvious. Do you think there may be other inconsistencies that cause the artifacts seen in the prints of the mini with the alpha version?

I did two prints one before and one after the update and the quality was actual slightly better and printed about 30 minutes faster. I've been printing minis for about a week now and all of them have came out really good for the most part (at least for a FDM printer printing minis). My mini is still running the first alpha release firmware.

  • Of course, I typed too much... Good to see you revisit this, and reminder "alpha and beta firmwares are not finished programs... use them to give feedback to the devs, not as review targets or production systems". I had my own experimentation like this. I installed the IS ALPHA on the Mini... it plasters labels that indicate it's an alpha on basically every screen. I did a small test not unlike the low poly wolf. The quality was nearly identical... but that wasn't what impressed me, what impressed me is that it didn't get louder. They managed to do a 20-40% speed increase with, for that test, no real quality changes... and it didn't get louder. Compare that to the MK4 which has rubber paddings between every bearing and mount (and is pretty quiet itself when printing at speed). I had a larger decorative print (2+ days without IS, 1.5 days with IS) and I opted to print the base (8h with IS) on the Mini before I dropped the big print on it... needless to say I went "ok, ALPHA is not ready to do the big print" because it had extrusion issues along the way and I didn't want that on the big print, which is currently printing on the MK4 instead. My expectation is that they're going to keep tweaking things on the MK4... a new firmware with features but also a slight adjustment to IS. Some extra settings in PrusaSlicer 2.6.2 and later. Etc. I did not have "Prusa Mini gets input shaping" on my bingo card, so it's impressive in and of itself since it's a lower-power 32 bit board compared to the MK4 and XL without the stepper cooling and physical parts to reenforce it. I will be curious to see future firmware on it (and the eventual final addition of power panic which has been "coming soon" since 2019 but has recently gotten actual code additions and configurations). Please keep contacting support on issues. The more they get, the more they either update their processes to include IS prints, but it gives real reason for them to do some code changes in the slicer and firmware (no really. Make a ticket on Github saying "there's ringing because I can't calibrate IS against my surface my printer is on", IF they ack. it, it just goes to a list that they may or may not get to. But if you contact support, and a trend comes up that ringing is happening, and support can't produce but you can, and they get photos and other things showing "yes, it's happening here. With proper belt tension, etc." then eventually managers review it and say "yo, fix this" and the engineers will be required to do such a thing and may eventually go "ok, we're gonna send you an accelerometer and instructions to run it. Please use it and send us the numbers back" and take those into account. It's hypothetical scenario, but people vastly underestimate contacting support for any company. If you ever read "why do they keep adding features we don't care about?! They need to listen to their customers!" yea, they listen to them via support channels... not random shoutings on Twitter and Facebook) I will have to look at that filament as it looks nice. Last on the accelerometers... , I don't see it in the current set of top comments, additional reminder that the accelerometers are used for calibration, not when the printers are running (as you seemed to discuss it). Also, I've mentioned it in Maker's Muse video (and others added onto it): there's been many "traditional" reviewers and commentors who have commented about recalibrating printers on different surfaces, but "klipper" reviewers (biggest being Nero) have commented that you don't need to and that the differences will be minimal at best on a properly tuned machine. Key words "properly tuned", such as belts. I know at least one Bambu user who swears on the recalibration fixes print quality issues when moved to new surfaces and such... but after poking them with questions, they admitted the only times they've moved the printer is when moving house, doing system repairs, etc. and that they often need to readjust the belts. So every time they had print quality issues, they adjusted belts, and then recalibrated and the issue when away... commentators on Maker's Muse video pointed out that it keeps being missed that the calibration is less to do with the surface it's on and more to do with the gantry's motion relative to the bed, so hanging it from rafters, hanging it upside down, etc. and other arrangements that will change that relative interaction, not unlike belts having more slop or backlash or stretch. I do hope they eventually either sell the accelerometers or at least indicate what senors they're using so 3rd parties can [provide them + firmware update so we can run it locally. It may not be needed, but having the option available is still useful. If anyone is wondering: the connectors Prusa uses on the MK4 and XL are Molex CLIK-Mate. So normal JST connectors won't do it.

Like i built a MK4 and nothing went wrong during construction, tuning was stupidly easy and the first set of inaugural test-prints all came out without a single little flaw with IS on. I expected some tiny little artifacts, but nope. It is perfectly fine. A BBL would have been cheaper sure, but i highly doubt it would have left me feeling like i acquired a device designed to outlast me if given the chance. I am impressed to see a company that actually delivers on promises even if later than intended.

This definitely isn't taken into consideration with the input shaper. I ended up taking a 1 inch thick piece of scrap sound attenuation foam from our assembly department and setting the enclosure on that. now the floor is supported and the ringing has been reduced but still not like it was before putting in the enclosure.

  • I wish you had tried the Prusa Mini+ with a Revo Micro. I've got Revo Micro installed in mine, but I haven't gotten around to trying the alpha firmware on it yet. What I've noticed with the regular firmware is that there is an improvement in print quality with the Revo Micro, including less stringing than with the default setup, so I wonder if it'd also fare better with input shaping.

    @WereCatf@WereCatf7 ай бұрын
    • Those improvements SHOULD transfer. I had 2 minis. 1 with revo micro and 1 without. The one with the micro did not receive the alpha FW, and the other one did. The one with the alpha FW had pretty bad print quality. I had made a profile called 0.2mm SUPERSPEED on the regular 4.4.1 (I think) FW where I basically doubled the print speeds. It was fast, but not alpha IS fast. The print quality was still really good, but there was some stringing since I didn't adjust retraction or z hop, those stayed normal. My takeaway was that the alpha IS was just not very reliable so I reverted back. When I did that, I think it reset all my settings IIRC. TLDR: probably wait for the official release. Now... let me watch Tom's video.

  • Hi Thomas, what I would really be interested in how the accerolometer is noticeable in reality. I don't think it makes much difference in terms of frequency. There is a test print at Klipper where the echoes are measured and the frequency is calculated. Marlin uses the same test print but does it differently. The print starts with 15hz input shaper and changes up to 60hz at the end of the test. So you can see very well the effect of the input shaper. And there you can see that it is not as extremely sensitive as many believe. There are other factors that play a role in the measurement at Klipper. Which input shaper, maximum acceleration or damping. But if these values are determined by an experienced team and it is ultimately only about the frequency, I do not necessarily see the need for a sensor. A video from you on this topic would be very interesting. It could be investigated what really affects the practice. Otherwise, I liked this video very much. Also please be critical when it is necessary.

  • Is the new firmware available for the older Mk3 printers, or is it dependant on the 32 bit board, which would make a HW upgrade necessary on the MK3 to a MK4 (at least partially)? Also does Prusa Slicer now support other printers that have input shaping and pressure advance (printers running Klipper, or converted to run Klipper) such as Voron?

  • It's not true that you can't tune input shaping without an accelerometer. You can always print the test model and measure the resonances manually, like what Michael over at TeachTech did maybe 2 years ago. And I'm pretty sure the MK4 allows you to enter the X and Y frequencies via the control panel.

  • I never heard about u were running input shaping for these 2 Prusa printers. May I ask if Input Shaping feature in Prusa machine is actually no needed to be tuned but pre-built into firmware in one-size-fits-all basis?

  • My experience with input shaping on my Mini is just about the same, much faster but with significant drops in print quality. I rarely print anything that takes more than a couple of hours on my Mini, so I suspect I'll probably end up using the input shaping selectively. Then again, with the Mini now running on the same codebase as the Mk4, and Prusa talking about more features coming in the 5.x firmware, I am really starting to think that one of those features might end up being MMU3 support on the Mini, since that seems to be the way things are going right now.

  • We run large structural parts once in a while where speed matters more than perfection. A real life example for a part taking 19h46m on mini+ 0.2 speed: with input shaper, we cut the time to 9h45min on the mini+, but here is the mind-blowing thing: Printing the same part on our new Bambu Lab in standard mode takes only 6h45m, and speeding up to ludicrous mode cut the print time to only 4 hours. It is mind-blowing that we have gone from 20 hours to 4 hours in a few months, it is a world of difference in the propotype phase!

  • I'm really curious about the mk3.5 upgrade and if that would be worth it. Especially with a revo hotend. While the mk3(s+) is older I think it still holds up to most printers out there. Feature wise too. So would the upgrade be a good idea and is therr any chance of input shaping working on it?

    @SirFridge@SirFridge7 ай бұрын
    • On the mk3.5 the mechanical parts are not upgraded and some of them might cause problem with input shaping, for example the heavy extruder motor and the slim Z rods. On the mk3.9 and mk4 the extruder is now a pancake motor and the Z rods are about 50% thicker, probably to handle better the fast accelerations needed for input shaping.

But overall, mini is now pretty capable small machine. And seeing quality improvement on MK4, I think mini will also be able to print nice with IS as without it.

  • What I don't get is that the "input shaping" is coming as an apparently uneditable setting in the firmware? From my experience with a voron those built machines, which are a similar animal to prusa (built from printed parts) the numbers from machine to machine would have some variance. Maybe someone with more expertise could counter that it wouldn't have that much effect, but I would think allowing some users to edit their own settings would be better.
