RE: What does the + mean?
"Hello.
Today I printed from this link: https://www.printables.com/model/1486513-prusa-core-one-to-core-one-upgrade-community-versi
Everything works correctly. Version 6.4.0 RC2 is installed."
RE:
Aha... that one... thanks.
But... i just installed auto-grill opener and started my first print with PLA. I intentionally closed grill. Nothing happened - grill didn't open. When it should open?
Is there anything else to be done?I did set it to auto in settings and i installed "thing" to the left two screws, as it was pointed out by users.
Worked for me. You have to switch filament types though. So start with PC-CF (for example) and it should close the vent. Then switch to PLA. It should open the vent. If you switch to PETG it won't open the vent again because it's the "same" type of filament (in terms of venting requirements). So basically it only triggers once when you swap filaments types.
The way to test is to send M870 O to open and M870 C to close over the console or create a text file and "print" it. I think it's a bug though that it is not forcing open or close before each print since it's possible (for example) that I'm printing PLA and for whatever reason the grill gets manually closed. The next print of the same won't open the vent. It's easy enough to add this to the start and end g-code sections.
grill_test.gcode
; Start with vent closed M870 O M870 C

Hm... that's not good... grill can be unintentionally moved at any time...
grill_test.gcode
; Start with vent closed M870 O M870 C
Thanks, that works, but other way around: O closes and C opens my grill. I'll have to figure it out why...

I raised a bug on this issue.
Really, it's opposite for you? O definitely open the grid for me and C definitely closes it. I think I know what it is. Did you flip the grid 180 degrees (turn it over) before you reinstalled it? The latch needs to cover a closed slot, not an open slot.
RE: What does the + mean?
Found it... i installed movable part of grid other way around... solved.
I think that we'll have to add this g-code to our profiles - at least until prusa changes this bug.
RE: What does the + mean?
My bug report is here, feel free to chime in:
https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/4956
After I get home from work I'll add it to my start/end g-code.
RE: What does the + mean?
I also noticed that open-close direction is quite opposite now (at least for me is): before it was right=open, not it's left=open.
After I get home from work I'll add it to my start/end g-code.
Since i'm not exactly "g-code pro" any solutions would be welcome if you choose to share... since it's not that easy for an amateur - it must be "if-then" sentence with filament type dependancy...
RE:
Only gripe is the boxy lid thing, If they can improve that then great...I get a feeling that wont be improved though, I guess thats Prusa's wheelhouse and they seem a bit blind to things like that.
Yeah it's really "bad" compared to the Core One itself. However, on the long livestream from formnext, one of the INDX guys said that you could design whatever you'd like, as long as you don't go below a 45 mm radius (spools apparently have a 90 mm circle where the filament string starts).
So you could simply cut into your top cover and print something to lead the PTFE-tubes.
Like a slot with a 45 mm radius rounded TPU insert.
I guess the MMU3 cover is quite efficient to keep the volume that has to be heated as low as possible, but giving the tubes enough freedom.
It really should've been some shaded transparent material though.
You have to switch filament types though.
Regarding the automated vent opening:
I'd really like the printer to close the vent after each job anyway, to keep out dust etc.
Btw: I've bought some black "organza" nylon fabric, cut it to the vent-sliding-panel and used a tiny drop of UHU max repair glue (stays slightly elastic) to keep the corners in place.
Slides very well and keeps most of the dust out, while restricting air flow massively less, compared to a solid grid.
I didn't really think it would work that well, but it's a 10/10 for me.
RE:
Something like this (I'm not in front of my printer to test though). I think it's a good idea to always close the vent at the end of a print. So this will only open the vent for the listed filaments and close otherwise.
; Start g-code section
{if filament_type[initial_tool] =~ /.*(PLA|PETG|FLEX).*/}
M870 O
{else}
M870 C
{endif}
; End g-code section
M870 C
RE: What does the + mean?
And for the people who like compactness this will work as well
; place in start g-code section
M870 {(filament_type[initial_tool] =~ /.*(PLA|PETG|FLEX).*/ ? O : C)}
RE:
Sorry, the above won't work. Apparently the ternary operator can't handle strings, only numbers so use this instead:
M84 E ; turn off E motor
G28 ; home all without mesh bed level
M870 {if filament_type[initial_tool] =~ /.*(PLA|PETG|FLEX).*/}O{else}C{endif} ; Open vent for low temp materials
{if chamber_minimal_temperature[initial_tool]!=0}
RE:
I have the MMU3 enclosed version upgrade so the top cover automatic vent improvements don't apply to my setup.
It was an easy decision just to print the new side filament sensor and spool holder parts myself.
The required o'ring for the new spool holder has been ordered (was about AUD$3 off Ebay).
Stickers don't matter.
If I was to buy the upgrade kit, I was looking at AUD $17.99 plus cheaest shipping option of AUD$64.99.
Prusa should investigate the use of cheaper options via normal post for those who can wait a few weeks for shipping of smaller items etc.
RE: What does the + mean?
I think that that cover is… well… ugly to say decently… beside it’s unacceptable to have all 5 spools just lying around like a bomb went off… so i made coreboxx and rewindr systems and i have my spools nicely stored on the top of the printer. And rewindr eliminates that bulky buffer
RE: What does the + mean?
Hello there, I have a dumb question regarding of the new spool holder. The product page claims this:
New Bayonet-Style Spoolholder: Allows you to use various spool sizes. Ready for a direct-feed drybox.
I feel kinda stupid. After printing it, I do not see how you can achieve that, either different spools sizes or the drybox. My guess is that you are supposed to design or find (Maybe Prusa itself will release new designs eventually) an attachment for those uses-cases, but I am not sure. Am I right?

That's basically the idea, like this for example: New Core One+ Spoolholder for 250G spools
RE: What does the + mean?
the holder is the change I did not implement. I am feeding from a quad dryer and I only use the side holder for quick jobs when it is not worth the hassle of removing a spool from the dryer, loading a new one, and pretty much immediately reloading the old one again.
I am looking forward to the INDX upgrade and the horror-movie style FTFE tubing from the dryer to the unit 😀 Even if it is in a remote room, I am going to hear from my wife about the optics of it 😀

I bought the plans for the INDXX box so that'll be my project until the INDX arrives.
RE:
Does anyone tried final version of fw ? Did prusa correct grill open/close at each print start or not? Is above code still "necesarry" ?

The released firmware will open or close the grill based on the filament that is loaded but it only does it once. It won't open (and never closes) the grill between prints with the same filament type loaded. The above g-code is not strictly necessary because I guess this is intended behavior and not really a bug.
However, in my view, this could cause an issue, especially with PLA if the grill is accidentally closed between prints. Which happened to me when I took the top off, put it on it's side, gravity closed the grill, I forgot to open it and on the next print my nozzle clogged. So I prefer for the grill to be forced into its correct state before each print, whether needed or not since the printer has no way of know the current state of the grill. I think a servo controlled grill would have been better but of course more expensive to implement I suppose.
I also prefer to have it closed automatically after a print since my C1 is now in the garage and I don't want dust to enter the chamber when not in use. Of course I used to manually do this before but now that it is "automatic" it should be one less thing for me to worry about.
Also, was pointed out to me that a better workaround is to do this instead which will work for any filament that doesn't require a heated chamber.
M870 {if chamber_minimal_temperature[initial_tool]!=0}C{else}O{endif} ; Open vent for low temp materials
RE: What does the + mean?
I asked because if i’m not mistaken a github case was opened for this exact purpose and when i’ve read that case i was under impression that it will be changed in fina version… but obviously not, so this code stays in my case. Like you said, it’s pretty easy to close the gril accidentally, in my case especially, since i have coreboxx on the top of my printer, so all filaments i use i load there, so that move lever is prety close.
