Five things you might not know about your Original Prusa i3 MK3

[@Lycius84]

Got my kit a few days ago, put it together and have been printing non stop. As others mentioned, the quick z axis move is fantastic.

[@NinjaClyde]

I like that quick Z-axis feature.

[@christiansprojects-cgmanuf1426]

Didn't know about the fast Z-Axis movment. Thanks! Your Printer ist absolutely awesome Jo, I love my MK3!

[@0calvin]

#6: Ship date ;)

[@structure7]

This

[@matteocristini6221]

Haha true!

[@MrSnowboarder0]

Three Year old comment, yet it still holds truth 😁

[@martonyoutube]

Its coming from czech so big ship date

[@MrSnowboarder0]

@@martonyoutube No, shipping isnt the problem. They are quite slow to produce, thats what takes all the time.

[@frogsareop5623]

I found out about all of these just from using my MK3S, I use the Z-axis all the time as I always need to clean the nozzle with my pliers (haven't even been using the nozzle long, only with regular PETG/ABS, and it leaks like *crazy* always curling inwards and getting everywhere, even mid-print).

[@thibfpv]

Whoo the Z axis adjust shortcut is amazing !

[@Robothut]

A great filament detector would be a rotary encoder, either optical or hall effect. That way both filament run out and filament jam could be detected. I am sure Prusa could design a 3d printed simple wheel that triggers a optical or hall effect sensor , the sensor output could be compared to the extruder stepper motor pulses for errors. Might be the ultimate filament sensor design.

[@MarkWheadon]

The MK3 does all that (detect filament jams and detect run-out) - with, I believe, an optical sensor designed for use in optical mice (mouses? :-)

[@MarkWheadon]

Really like that long-press to move Z 👍

[@bebedasilva9700]

Thank you! Make it so easy to change filament.

[@valida85]

just bought the mk3 cant wait to get it put together i would love to see some multi color prints

[@jmsaltzman]

Thanks! Loving my MK3!

[@Iwekzy]

Why is that printer not printing parts for my kit right now?

[@spikekent]

Fantastic Josef

[@mlorenzati]

How do you manually move the XYZ axis in fraction of a millimiter? I'm using it to do PCBs too and when setting my own initial position, the Z is either high or too low with 1 mm.

[@danthwad3r451]

Great video! Thanks Joe!

[@omegaclark5248]

Tip 1 is gold

[@martincaneva4247]

0:44 whats PID calibration ?

[@Prusa3D]

help.prusa3d.com/en/article/pid-tuning_2265

[@renterjack]

really hoping this works on the MK2S. that fast z is just what ive been looking for. menuing into it to z up is a pain.

[@TheMikolasZuza]

It does work ;)

[@MarkWheadon]

It works on the MK2S? Who knew? (I certainly didn't :-) Excellent.

[@christopherparker1823]

Very helpful thanks

[@Nachmed]

That's awesome, dude!

[@nolesen5699]

ok man, Where is the stl / gcode for your new spool holder? I want it!

[@Prusa3D]

Hi there! You can find STL file on our website: www.prusa3d.com/prusa-i3-printable-parts/ Gcodes comming soon. ;) Happy printing!

[@buas7]

got the same filament holder but i made it longer zo it can hold 3kg rolls

[@dwainmorris7854]

THANK YOU !

[@zimmy1958]

great info. thanks

[@envt]

Whats that fan on the extruder stepper motor? :)

[@Ed_Stoddard]

It was an add on print that shows the extruder motor turning. They had several designs available.

[@ultrawide5900]

There is an article about these visualizers at prusaprinters.org as well :)

[@structure7]

[@MarkWheadon]

Looks like a very bad idea for anyone who has (or has anyone in the household who has) long hair...

[@SianaGearz]

It's just hanging on the axis with a neodymium magnet. The worst thing that can happen is that it'll fall off, so you just pick it up and put it back on again, you can't lethally entangle yourself.

[@cthulpiss]

When will those be available in MK2S firmware?

[@DatMischael]

As i know, filament change, PID calibration and Fast Z movement are already possible at the MK2. Bending bed ofcourse not, and didnt look for the sensor reading yet.

[@falcon3dparts]

Where is my 2.5 upgrade I ordered in October?

[@Hopeinformer]

That is so awesome! It's making me anxious to receive my MK3. Quick question. Why are the printers labeled with "i3"

[@enlightx]

it stands for iteration 3, look up early reprap printers and you will see how prusa released his early designs and he updated them a lot but major changes are iterations i personally build I2 and I3 prusa printers many years ago and i can happily say the I3 MK3 is the best printer iv built

[@Hopeinformer]

Luke Turner, thank you Luke for your reply and explanation. Now that makes perfect sense.

[@Hopeinformer]

Oh my gosh, wow! You're right. Looking at that printer the Mark 2 and 3 seem to have evolved tremendously. That's so cool. Thank you for sharing that. 😁

[@kraken3d718]

Probably still printed better than most MK3 though.

[@erikcramer]

What about the remaining print time?

[@MarkC-1970]

How do I get support for a 6 week old mk3 that has failed? I purchased it from a 3rd party who is not knowledgeable and the Prusa forums are not helping me. The printer was great for the first month and printed all the prototypes we needed but now it is an expensive paperweight. Thanks.

[@christiansprojects-cgmanuf1426]

What's wront with it? Maybe someone can help you here.

[@kox-killzcymerii3322]

Did You Fix It? Xd

[@fischer1672]

Fantastic!

[@wittsullivan8130]

Here's something I didn't know. The filament detector is turned off by default, you have to turn it on yourself.

[@Hi-wm6nb]

Really? How can I turn it on? Or was this changed to the MK3S (My printer)

[@AlfredoAntonioMartinez]

why you dont use full graphics display? it is something about the performance of arduino? thanks in advance!

[@LogicalWaste]

because they want to focus on things that help print quality. a touch screen or larger screen would cost time and money, increase unit price, and have zero effect on print quality. purely cosmetic, effectively.

[@MarkWheadon]

In short: yes. The Prusa only has what it needs in terms of processing power - a simple 8 bit processor. Neither printing quality nor speed would be improved by having more grunt, so it would just make the printer more expensive.

[@mamber1100]

Yeah... Prusa is great. But have some problems. In new version (MK3S) power panic does not work. Printer not startig in point of break. And big problem for me - sensor don't sense filament flow. It try to sense end of filament, not flow filament. Many times my nozle is block, but pinter "printing" in air. Many hours of print is waste. But, yeah nex but... ITS REALY GREAT PRINTER

[@cymond]

That's funny, I have the opposite. IIRC, Power Panic is not supposed to activate if the power switch is used, only if the power is interrupted externally, but it does on mine.

[@LogicalWaste]

Hey josef, will that quick Z-Height make its way onto mk2s firmware? Thanks.

[@TheMikolasZuza]

It works on MK2S ;) It's in Marlin firmware which is the base for both MK2 and MK3 fw.

[@Mike_zxc]

It's always been on the MK2S, I found it by accident and have been using it ever since.

[@ScottLemmon]

life changing

[@timfredriksson3245]

I knew all the features before. Okay not the pid calibration thing but all other thing. I use the z axis most of all the features in the vid.

[@ArcAiN6]

You should have a contest, where the winner gets an original prusa i3 mk3, and only let me enter the contest. just saying :D

[@TheDigitalsun]

All good but my printer does not unload filament like the one on the video. Seems many folk are having this issue also. Can we get it fixed, the Firmware upgrade did not improve it.

[@Game-Univ]

David Young there’s more issues too,I’m having issues with the fan is one of the things people also have problems with,after one week the fan started to fail and now I have my printer just sitting in my room waiting for a replacement fan

[@101rotarypower]

Does anyone's MK3 eject filament without catching on the top ptfe if not pulled through quickly and vigorously? Mine still catches even if I am ready to pull as it's ejecting. And if not pulled as it's hot and ejecting, the melt zone comes up, and refuses to eject if left for even a few seconds.

[@MarkWheadon]

My MK2S has done that for a long time now. I just pinch off the extruder tension and pull the filament out - much quicker and works just fine. Presumably the MK3's extruder will let you do that? (Let you squeeze against the extruder tension so you can manually pull out the filament.)

[@tooez7397]

I'm doing everything wrong. The way I change my filament is by cutting it near the extruder lol

[@mamber1100]

And one more thing. Maybe in next generation You could try to do extruder like a module who we can easy on and off. Replace of nozzle or even heatblock is verry hard, when You must do this Up side Down

[@Chris-xh4hw]

Can PRUSA i3 MK3 Laser engrave 4mm high lettering on Acrylic? I am thinking of flight simulator panels.

[@AquaticSCP]

......................ummmm................ ITS A 3d *PRINTER*

[@dhruvbose8294]

Are some of these features common in the ender 3 as well?

[@Fejszi]

No

[@ruwo7697]

nice

[@ImGriffinP]

Not to be that guy but you spelled successful wrong in the unload menu.

[@TheMikolasZuza]

I went to github to put in a pull request to fix it, but someone already fixed it :)

[@Klepczar]

1. realy!? after 2 years using?

[@janimrich]

Your filament spools are pretty dusty :-)

[@garrydye2394]

One thing you might not know is the Y axis is loud as hell in real life.

[@BedardTruther98]

tfw you forget to grease moving parts

[@antcri730]

Number 6, Its ridiculously overpriced.

[@alsmith1025]

they sell crap parts that burn up and provided crap customer service.
