How do I make it louder tho? I WANT my neighbors to know I'm printing my 27,000th boat

[@3DMusketeers]

loudspeakers and amplifiers.

[@ulaB]

@@3DMusketeers Or just an Ikea lack table.

[@3DMusketeers]

LOLOL same same

[@falxonPSN]

Subwoofers. Always subwoofers.

[@Markevans36301]

I feel kind of bad I've never printed a boat.

[@JHittle]

Nice can wait for the release to try this out....

[@3DMusketeers]

It's in beta still I think, but you can load it on easily.

[@eric_r_colby]

Dang that alpha is so promising! Are you building a custom enclosure or going prefab?

[@3DMusketeers]

maybe both, dont know yet.. Not sure when the first party solution will be available.

[@RichardR140669]

did you re-do the tool offset calibration after you updated? i tried and on mine it fails every time with Alpha 6.0.0 when I go back, offset calibration passes

[@3DMusketeers]

nope, you are not the first to ask me, I didnt have to do it.. But I didnt do a multi head print either.

[@michaelschuler8984]

I want to like this machine. After we add our second Voron, almost built, I really would like to get a Prusa XL but a have believed that it is still in beta even though it is in production. I have seen some good things our the last few months and hopefully by the time I have the money it will have all the firmware figured out because I really want a 5 toolhead machine.

[@3DMusketeers]

I dont feel like it is in Beta, I feel like it is getting better than I bargained for. I did not buy a machine with input shaping, but I got one. I did not buy a machine that is darn near silent, but I have one now. My cost? Nothing extra. Gotta love that. Sure, if you consider the landscape NOW, it feels beta to some extent, but when you consider when many of us first purchased it, this is amazing to have and is now my quietest printer, I THINK.

[@falxonPSN]

@@3DMusketeers I'm with you, but only to a point. The dramatic price premium they charge does mean that many of us have higher expectations, and I feel that's rightly so. Sure, the Bambu printers waste massive amounts of material and cannot do dissimilar nozzle temps, but they are a small fraction of the price and have a much better user experience in some key areas. So I'm not quite willing to let Prusa off the hook so easy. Once they get true multi-sized nozzle printing working properly, as they hinted at during the product reveal - years ago - then I'll consider the promise fulfilled. They are not far off now, aside from crappy network hardware choices.

[@jamesm5200]

Looking forward to this upgrade making its way to the MK4. There are certain moves that I can hear throughout the building... As an FYI phase stepping is not input shaping. Phase stepping changes the input to the stepper motor to more resemble a sine wave rather than a square wave, whereas input shaping aims to 'predict' system resonances and adjusts the input steps. I'm an electrical engineer; the nuances of motion systems get complicated VERY quickly. Phase stepping can sometimes reduce motor torque, so I'm curious if this change will introduce any 'missing steps' (layer shifts).

[@3DMusketeers]

I think the MK4 would need an additional accelerometer, but thats okay! Noted RE: Phase stepping.. I should have looked it up, but I didnt...

[@Govinator]

I’ll have to try it out on mine! I have mine in a closet next to my bed with my other printers but it’s been too loud to ever do 24hr+ prints without losing sleep lol.

[@3DMusketeers]

I would be cautious of having printers that close to you no matter what, regardless of sound, but you do you, I guess!

[@falxonPSN]

I have been pleasantly surprised/shocked with how much of a difference the 6.0 alpha FW makes in concert with the newer slicer that disables helical lifts. Before 2.7.2, I ended up having to make a fork of PrusaSlicer to force those lifts off since they were ruining my print surfaces. (That's not the only reason, admittedly - my "MultiTool" fork also allows the wipe tower in many places where the stock slicer doesn't like using different nozzle sizes.)

[@3DMusketeers]

right?!? kinda crazy..

[@mariuszstanisz9070]

The more exciting thing for me is that there is a built-in accelerometer in each buddy board. That means one day they will release fine-tuning for inputshaping. Does the MK4 buddy board also have it built in?. Why do they keep calling it RGB light strip when it's only white light. One feature they should add is auto-shutoff of both the light strip and LCD screen. Also, they still need to quiet down diagonal movements above 150 m/s. Did you have to do nozzle calibration as well? Only reason why I did not flash mine yet. As a side note, the ObXidian .4 nozzle seems to eliminate almost all stringing even with silk PLA.

[@elchavode6479]

From my understanding mk4 doesn't have them

[@3DMusketeers]

I do not believe the MK4 has it, but I believe there is provisions to add one. Do not quote me there though.. I dont mind some of the diagonal movements being loud, that is what it is. Every printer we have has issues with fast motions and noise, it is seemingly a fact these days. No nozzle calibration (I had done it when we built the machine), just the resonance calibration which is only done for TH1.

[@langph]

It is RGB: in case of a failure the light turns red

[@3DMusketeers]

true, I do like those colors, but I get why some dont

[@ovDarkness]

In machines that are repeatable and unmodified there's no need for "fine tuning". This is because the band of the input shaper is typically much wider than a deviation in resonance frequency. Watch Michai Designs interview with Duet 3D engineers.

[@saulrecktom5310]

First I have to fix why the Wi-Fi is not connecting now. I changed my mesh network.. same name and password. But there may be a space at the end of my SSID... Wondering if a space at the end makes it impossible to connect. The wifi icon comes on for 1 second then ever to return after loading credentials. Need time to contact support. Any ideas folks

[@3DMusketeers]

Not a clue, 100% sneakernet for this machine and I. Never bothered to put it on the network yet.

[@berlinberlin4246]

If i remember it right a Space at the end of the SSID is not in the 802.11 standard so the manufacturers do it in some way there like...

[@Tombaumgarten]

I hope the bring something to the MK4 and make it more quiet too.

[@3DMusketeers]

I believe it will need an add on accelerometer, but that shouldnt be too bad!

[@ulaB]

My XL5 is so quiet now I got mad that I didn't have the firmware before and started developing a time machine to install the new firmware a few months ago.

[@3DMusketeers]

ha ha, right?!?!

[@RedSlashAce]

I am definitely tempted to try the beta firmware. Bit hesitant though since it apparently disables crash detection...

[@3DMusketeers]

I believe it is always off for input shaping, but I could be wrong there?

[@josefgoedde6592]

@@3DMusketeers I accidently witnessed crash detection and print resuming with input shaping. Worked fine.

[@therick0996]

it's wild you can turn phase stepping on and off while the print is running

[@3DMusketeers]

yeah, its kinda cool!!

[@falxonPSN]

Just be careful with this. A number of us on the forum thread have reported issues up to and including hard lockups when doing that.

[@soundspark]

Too bad right now I blew the motherboard on my Voron, and am waiting for a replacement...

[@3DMusketeers]

oh no! What happened!?

[@soundspark]

@@3DMusketeers Short circuit fed 24V where it doesn't belong. Replacement coming tomorrow or Friday.

[@3DMusketeers]

oof :(

[@soundspark]

@@3DMusketeers Just got the replacement board, accidentally got an Octopus instead of an Octopus Pro. I guess that's just 1 line of config to change. Got around to recompiling my Klipper for the replacement board, realized I had not updated in a long time.

[@elchavode6479]

The bugs are the only reason i havent installed the alpha. But looking forward for beta release.

[@3DMusketeers]

The bug I had isnt related to firmware alas :/ hopefully Beta will be out soon though!

[@ulaB]

I didn't have any issues so far. It's definitely worth a try and you should be able to go back anyway.

[@elchavode6479]

Does prusa even give anyone special treatment?

[@elchavode6479]

To add Prusa seem seem give everyone same threatment and good service.

[@3DMusketeers]

I dont think so? but hey, shoot your shot, right?

[@3DMusketeers]

lololol

[@awilliams1701]

time to bring the XL inside so it will work better. lol

[@3DMusketeers]

it really is..

[@johnpapiewski7022]

80% reduction is about 6 dB. 95-98% gives close to 20db,

[@3DMusketeers]

Pretty crazy right?!?

[@michele_for_prusa]

The reduction is not quantified in a decibel scale but refers to the microscopic oscillations produced by the motors during the X and Y movements. While this will drastically reduce noise, other parts of the printer will still produce other kinds of noises during the operation. On a side note, phase stepping is also meant to partly improve the print quality! 🙂

[@3DMusketeers]

correct. We dont have a chamber to do proper testing of noise. The post alpha was quieter, other than on fast travel moves, than my noise floor on that set.

[@Rob_65]

Your video does not show the real amount of noise from this printer. I also have a 5 headed XL and it screams ... At certain speeds it sounds almost like the printer is coming apart and that is not because of the this metal sheets. With my office door open, I get a good audible feedback from the printer being in the room next doors, 5 meters away from me 😮 I'd love to put the new firmware on mine, but it is used in production and I don't want to risk slowing down production due to bugs/changes in the firmware that affect my printer output. Next thing to tackle is the cooling. Better cooling will surely also help creating support that is easier to remove with less visible 'damage' to the part. I am used to be able to get ABS printer perfect parts with easy to remove supports that do not leave any visible damage to my parts but on my XL, support always sticks too well to my parts.

[@3DMusketeers]

I have such issues with bed adhesion, we did what we could. Humidity here is a big issue. So far I have not noticed any game changing bugs, but downgrading takes only a few minutes to flash too.

[@Rob_65]

​@@3DMusketeersHumidity could actually be why my colleague has problems with his XL. He is on holiday now and I am now testing the alpha 6.0.0 firmware on his printer, sounds very good and it seems that the bed adhesion is fixed too. But I guess that is due to a change in the weather (nice moderate sunny instead of cold and rainy 😁)

[@3DMusketeers]

could be!!

[@StumblingBumblingIdiot]

I cant afford the XL but would love to see if there is any difference in actual print quality with it on and off.

[@3DMusketeers]

I need to fix my bed adhesion issues first, but yes, it is on my list to test. The issue we have is that I cant get my garage dry enough to get things to stick to build plates well without some sort of adhesion promoter.

[@coreyfro]

@@3DMusketeers on my XL, I just print the first layer glacially slow. I haven't used my PCA Hairspray trick, yet, but I haven't been printing PC.so I haven't needed it.

[@3DMusketeers]

I will have to try it out! I just hate putting sticky stuff on the beds!

[@coreyfro]

@@3DMusketeers I take a olive oil sprayer, fill it halft full with 60% isopropyl, and add a cap of PVA 150ml 60%, 15ml PVA Shake, pump, spray. Works best on satin sheet.
