I wonder when we’ll get upgraded one and a new resin printer from them

Old printers? It's a buddy board printer! It's very new! I want to see input shaping on the Mk3! (Marlin has input shaping that was written to work on all the 8 bit boards!)

@ElectraFlarefire Sure, but MINI is here for 3 years. I saw sth about IS on 8-bit MCU, but MK3 can be upgraded to MK3.5, which should be easier for integration current solution by Prusa. And to be honest, debugging and developing new features is much easier at 32-bit platform MCU these days.

@@ElectraFlarefire Don't worry, it's not an old printer. This is already a museum exhibit 🤣😂

​@@27Damianwhat should creality users say about that?

u say this but i dont see input shaping on a mk2

​@@Mr_Pewpy_But-Whole bruh

@@Mr_Pewpy_But-Whole Maybe the main board of the mk2 has not the capacity for that new firmware. So even PRUSA can't upgrade it with any magic.

@@caspar3152 Input Shaper is only supported on newer 32-bit control boards

​@@Mr_Pewpy_But-Wholealso MK2 will be 8 years old

ikr.. mine doesnt do this... maybe this is their response to bambu lab a1 mini

@@trevorbelmont4633 You need to upgrade to the IS firmware, and then you should be able achieve nice speeds, I know I certainly have.

Yeah I was waiting for awhile and I never printed a Benchy. So with no context I was confused. Plenty of mini owners like myself aren't very technical. 😢

@@kvol1668 But at minimum, you can see how fast it is compared to your printer right now. Yeah it's kinda lame they have the explanation in the link/description but cmon

Fast? It's just a single perimeter and almost no infill. 🙄But I haven't seen a Mini and it's original speed. If it's still increase that's good.

A proper SpeedBenchy on a MK4 is about twenty minutes, and since the "Bonkers Benchy" on the MK4 is 12 minutes vs the Mini's 16 minutes, I don't think the Mini with Input Shaping is too shabby...@@hologos_

Omg SO brill

What rules doed it break? From some of the atrocities I've seen for WR attempts this is a perfect looking 3D benchy?

​@@Zwettekopthe rules don't stipulate it needs to look nice but they do stipulate certain layer, walls, and infill. It's actually what they accused their competitors of, being disingenuous. Awesome job with the new firmware but they shouldn't call the kettle black

there are standardized rules about wall count, infill, layer height and so on to make speed benchies comparable. this looks to be less infill, one wall instead of two and could be any layer height@@Zwettekop

​@@TheLordiniobased on the file name it's .25mm layer height.

​@@Zwettekop it should have two perimeters but this only has one. Also it’s supposed to have 10% infill, and this is using “lightning” infill. It also should have 3 top and bottom layers, and this appears to be one or two.

I won't complain though, I have my MINI and 0 intention of getting a new printer so it is great to get a better printer escentially for free

i have the mini+ and the bambu X1C, best of both worlds!

@@kneel1 How do they compare? :)

Not in a stock firmware but if you have an rpi you can install klipper and half the same speed and input shaping improvement

@@dougshellusn Or install Marlin and enable it's Input shaping. It was written for 8 bit boards.

​@@ElectraFlarefireinput shaping only works on 32bit boards

@@aregulargenericname8794 Nope. Marlin's input shaping was written for 8 bit Atmel boards. There is a bunch of forum posts from the guy who wrote it.

I was always going to keep my mini because it sits on my coffee table and entertains like a having lava lamp, but now it’s a super fast lava lamp! And not much louder than it was before.

No

I got mine this February, couldn't be happier with a printer in my life, you should get one, it's small but an amazing printer

It's not yet an official stable release. What they've released is an alpha version of this new firmware and that means there's still a lot to test and it's reasonable to expect some issues that will be fixed before these new features end up in an actual stable release.

no, it's software only.

@@REDxFROG Of course you are right, but I feels like switching from an HDD to an SSD. :)

Probably. Though it may need some community tweaking to get the best results. Considering the print-head's weight will be slightly different compared to the vanilla head.

Tbf the tool head mass won't change on this either. The bed will be heavier though

@@tjCooper88 You're comparing a single axis tool head to a dual axis

Very little. Resonance drift is relative to the Proportional change in Mass. Basically to keep drift low, you either keep the weight constant, or significant enough that the change in weight is rendered insignificant. On which a print Bed has so much mass that its resonance doesn't drift much even if you print a big solid wad of plastic on top of it. If you sacrifice some speed to allow for significant tolerances (mandatory for "universal" settings like this) and/or anticipate the drift in resonance by tracking the amount of material being added. It can be consistent regardless of how much plastic you plop on it. On that i wouldn't say Input shaping is more suitable for CoreXY, but that it is significantly easier. Input Shaper can be effectively used with every style of CNC machine. Be it Cartesian, Mendel, CoreXY, Delta or even Polar. Just takes more work to get it good. But if you can implement IS, you honestly always should.

@@chielvoswijk9482 You said it yourself "proportional to change in mass" How much do you think an average bedslinger bed and gantry weigh? A lot less than a 1 kilo spool of filament... so it would be off by a factor of 2 if the bed is assumed to weight 500 grams... I wouldn't call that "very little" at least in my case.

@@hd-be7di I'm trying to keep it simple for sake of a comment, not a lecture. My fault for reducing it too much resulting in loss of accuracy. i guess. An additional factor i skipped is that with a decrease in base frequency. The sensitivity to resonance induced artifacts reduce as well. That at a high-frequency any resonance will be exhibit in the output, while at low the resonance needs a significant amplitude to become apparent. Basically. The heavier the gantry, the less Impact drift will have and the easier it is to compensate. Pretty sure that past half a kilogram plastic it doesn't even matter anymore due to the gantry being so cumbersome any resonance is muffled. Part as to why you kind of need a accelerometer if you want precision with a super lightweight print-head. The lighter, the higher the frequency, the harder it gets to hit the sweet-spot in calibration. Regardless my point still stands. All forms of CNC machines no matter the construction can benefit from the style of PID Regulation that lies at the heart of Input Shaping. Some easier and more drastically than others. There is no sense in discounting input shaping just cause a printer isn't a CoreXY...

Cause the MK3's controller can't handle it. The Mini+, MK4 and XL all have modern 32-bit ARM controllers running at 168Mhz and up with a good amount of memory. While the MK3 is using a 19y old 8-bit AVR controller running at 16Mhz with very little memory. That just isn't remotely enough for Input Shaping. (It is also why the old models were still using monochromatic LCDs for so long)

Hi. You Flash the firmware, load the new profile in Prusa Slicer (menu Configurations > Check for Configuration Updates), and create the Input Shaper gcodes with this profile.
