Firmware 3.3.0 for Original Prusa i3 MK3  

Re: Firmware 3.3.0 for Original Prusa i3 MK3

Hi RetireeJay,
this is a very strange behaviour. I've flashed 3.3.0 to several printers and no issues at all. Are you running stock parts, or do you have some mod? Ideally please start an issue at GitHub to alert the devs: https://github.com/prusa3d/Prusa-Firmware/issues

Re: Firmware 3.3.0 for Original Prusa i3 MK3

Well, the problem is solved in one sense, but quite mystifying in another. I had previously modified the source code to compile my firmware with bang-bang control for the bed heat. This time, I had failed to make that modification. It turns out that apparently once you have implemented bang-bang control of the bed heat, there's a bit set somewhere that does not get reset when you upload firmware that uses PID control for the bed, making PID control fail. I tried using the "factory" versions 3.3.0, 3.2.1, 3.2.0, 3.1.3, and 3.1.1 and none of them would heat the bed. But once I commented a single line in Configuration_Prusa.h (line 432 //#define PIDTEMPBED), the bed started behaving normally. I will raise this as an issue on GitHub.

Supposedly failed, looks like it might be OK? Printer says it is on v3.3

avrdude done. Thank you.


Tried 3.2.1 now, the output is a bit different, seems like 3.3 is trying to do something more and failing at it?

Re: Firmware 3.3.0 for Original Prusa i3 MK3

I'm having the same issue with filament use not being recorded. Also, the statistics screen flashes and stutters during a print. Print time seems normal, however. Thanks for all your hard work, Prusa devs! Hope you guys can fix this issue soon.

Re: Firmware 3.3.0 for Original Prusa i3 MK3

Just upgraded to the latest firmware(3.3.0) and now, I cannot print without interruption !

1-SD card print: Printer just stop in the middle print showing no error.
2-Print with pronterface: Printer stops every 10 minutes with error code:

File "printrun\printcore.pyc", line 471,
in _print File "printrun\printcore.pyc", line 545,
in _sendnext File "printrun\printcore.pyc", line 567,
in _send MemoryError

Has resorted to downgrade firmware. Any clues ?

Re: Firmware 3.3.0 for Original Prusa i3 MK3

updated to 3.3.1

have display issues. no matter which language, there are blocks in some lines - not text....

Re: Firmware 3.3.0 for Original Prusa i3 MK3

I've just gone from 3.3.0 to 3.3.1 and found the text on screen to be fine. Have you tried a full factory reset? (Hold dial down as printer is powered on, then release when you hear the BEEEP). Are both cables between screen and Einsy connected OK?

Re: Firmware 3.3.0 for Original Prusa i3 MK3

After the upgrade to 3.3.1 from 3.3.0, all of my prints immediately started failing the bed level portion of the print. I went ahead and had it redo the Z axis calibration and then everything started working perfectly again. I physically changed nothing.

Just an FYI.

Re: Firmware 3.3.0 for Original Prusa i3 MK3

something went wron when flashing.

did it again - now the printer works better than ever before.

That seems to be the best process lately and really doesn't take too much time for peace of mind. I think a lot of problems arising from these new firmware revisions would be resolved if a full wipe is performed.

Should this be updated as the link is directly to the 3.3.0 tag rather than the tip production release. I would guess many folks are quickly skimming and grabbing it without knowing that there is a later release.

Re: Firmware 3.3.0 for Original Prusa i3 MK3

I have the same issue as bellow.

Slic3rPE-1.40.1+linux64-full flashing v3.3.1-845.

Fail messages at the:
avrdude: prusa_init_external_flash(): MK3 printer emitted incorrect cfm code: `echo: 3.3.1-8`
avrdude: arduino_open(): Failed to initialize MK3 external flash programming mode

LCD shows 3.3.1-845, and it prints.

Supposedly failed, looks like it might be OK? Printer says it is on v3.3

Re: Firmware 3.3.0 for Original Prusa i3 MK3

I received my MK3 in February an assembled printer and had no issues printing out of the box, when new driver and firmware was installed had no problems installing, when I tried to use the layering I received error messages which said I had a windows driver missing also graphics card issue. My computer was 7 years old was a windows 7 updated to windows 10. My son had a new computer he uses to play games on, we installed Prusa software on it no problems, I bought a new computer. I have had no problems since.
I have been working with CNC equipment since 1973 the Construction Company I worked for bought 2 CNC for rebuilding heavy equipment under carriage parts they had 5 tool heads for the different operations, they where programed with punch cards and run with tape reels. No PC's in those days and no internet, if you had a problem long distance to Italy.
I wrote my first computer program in the early 1980's with Microsoft Basic which is a long way from today. I have a CNC I use to do wood work for 11 years.
We all are downloading the same software to run our Prusa printers some are having problems some are not. I work with computers 5 days a week and have seen every issue that you imagine, al lot of them are with drivers, my issue was a computer that needed driver update and a updated graphics card. If I was to see that I was having a problem and you are not and we have the same Prusa printer but we don't have the same computer, I would look at my computer real hard.
I own two knockoff printers that bought a year ago I put together myself that where a nightmare to set up and print. The Prusa MK3 prints are awesome, the only thing I change sometimes are the temperatures.
I have had no extrusion problems, I have had the power go off and when the printer restarts smooth as glass. I ordered the MM2 can't wait.

Josef keep doing what you do. I turned 80 in June and found out you are never too old to learn. thanks Norm

But because yours is running fine and someone else's isn't doesn't preclude the possibility that there's an issue with the printer. However, you're correct in that one should always start with the basics... Is it plugged in?

Re: Firmware 3.3.0 for Original Prusa i3 MK3

To clarify what I was getting to, if the downloaded drivers and firmware are not operating right, it could be the windows drivers need updated, it is what happened to me, also the printer not operating right could be that the printer is not calibrated correctly. I built two 3D printers from kits and found that if I wanted a proper print everything had to be correctly put together. When I started 3D printing I was lucky to have a person who works with 3D printing at an aerospace company he was a great help with the setup of the printer kits and the storing of the filament to keep it dry with desiccant packs in plastic bags, when I am printing I use a Polybox from Polymaker keeps the filament under 20% humidity the garage I was printing in had a humidity of 70% + that's Florida for you. The difference in a print with filament of 70+ % or less than 20% is like night and day. The CNC that I use for woodworking, the wood needs to be around 11% humidity. I know that there has been things that Prusa had to correct like not counting the filament etc. they react to them in a promptly.

Understood and agreed, at my previous employer and we started having all kinds of strange issues with our modeling software crashing and certain modules not working properly. After several reinstalls and and calls to the modeling software's support it turned out it was the updated Nvidia quadro driver that was causing the issues, oddly enough it was only happening on a few machines, in our case a video driver downgrade resolved the issue.

Re: Firmware 3.3.0 for Original Prusa i3 MK3

I got some problems after flash 3.3.1 firmware.

1) Can't move Z axis on LCD, the menu show but rotate the knob do nothing, lcd digits don't change. It start work after i print something from sdcard
2) Very slow print from octoprint, print constantly stop during some large seconds and then do the next step and keep doing that. Work just fine before the upgrade. Print from SDcard is OK.

Anyone have this problems?

Re: Firmware 3.3.0 for Original Prusa i3 MK3

UPDATE: Version 3.3.1 is out! https://shop.prusa3d.com/forum/hardware-firmware-and-software-help-f64/firmware-3-3-1-for-original-prusa-i3-mk3-t23335.html#p99345

RE: Firmware 3.3.0 for Original Prusa i3 MK3

I hope this is the best spot for this. This month I upgraded my i3 MK3 to MK3S with the new filament sensor. Everything is working great except that it will print (go through the motions) even when there is no filament in place. This happens in two instances that I've noticed. One is if I fail to properly feed in the filament after a color change and prematurely press the button in response to the question about whether the filament fed properly and the color is correct. It will just proceed merrily on printing air. Likewise, if it runs out of filament, it just continues. The first instance has happened a couple times and the second occurred during a specific test where I just cut the filament line to see what it would do.lk

After the upgrade, I checked/tested the filament sensor in the hardware settings area and it dutifully acknowledged the presence of filament when in place and noted its absence when it was gone. After the hardware update, I d/l the current firmware (3.13.2) and the latest PrusaSlicer 2.7. Everything has worked fine after the upgrade except this particular issue. Any insight would be appreciated.

RE: Firmware 3.3.0 for Original Prusa i3 MK3

Still hoping for some thoughts on this issue. I am concerned about leaving the printer on overnight and then running out of filament or having it break. Thanks again.
