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: What does the + mean?
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 99% of dust out.
