Elegoo Centauri Carbon

I was a bit surprised that you had deleted the URL for that Bambu Lab thread about the brittle filament from my comment - then I realized that you had not deleted it, but that I forgot to include it.   Sorry about that - there is some more information, and other ideas there. You may want to take a look at that thread, along with looking at other search results.

Thanks will check it out. No worries.

For this see "Link Here", but same PLA+, so clearly it's probly either setting in slicer or a diff in the printers...

Scrapy device provided, odd having to print one, but prints come off really easy.

Mod to hold glass top to side of printer. Pretty snug, so it don't giggle at all.

Ok, first maintenance issue. Clogged nozzle.

Tools Needed:
   -Tools inc from printer or Allen wrenches.
   -6 mm wrench
   -5/16 wrench
   -Needle nose pliers or multi-tool pliers.
   -5/64 drill bit
   -Nozzle cleaning tool. (Whatever the heck the sharp wire is...)

1) Shouldn't have to say, but keep the hotend cold. Pull out bowden tube.
2) Pop off front fan cover, literally magnets hold it on. Disconnect wire.
3) Push cutter on side.
4) There are 2 screws on top of hot end. Remove screws and there are 2 small connectors, 1 for heater, larger, 1 for temp, smaller. Carefully remove.
5) There are 4 screw on the sides of the hotend assembly. Remove all 4. Pull off cover.
6) There are 3 screws holding the extruder cover on, pull off, NOTE: The cutter is on here, USE CAUTION as it's basically an X-Acto blade.
7) There is a larger gear here, pull out and check extruder for clog. Replace when clear n replace the 3 screws.
8 ) Replace cover and 4 screws.

Nozzle:
1) Pull black cover off hotend bottom.  Keep note of the 2 sets of wires how they are on the hotend.
2) Use pliers to pull metal sleeve out of black sleeve.
3) The black wire is the temp sensor n the small white thing is the heater, they will fall off, keep note of how they wen if they didn't fall out.
4) I used a 5/16 wrench on the heatblock and 6mm wrench on nozzle, remove.
5) I used my pliers and a candle to heat up nozzle to try and remove filament.
6) If nozzle is clear already, and nozzle cleaner goes through ok, goto 10; otherwise continue to 7.
7) Replace nozzle in heatblock n tighten.
8 ) I used a 5/64 in drill bit in my cordless drill to put the bit into the top of the hotend and using super slow speed, pushing the bit into the block slowly removing the filament as far as possible. I use super slow to keep from damaging the inside of the passageway.
9) I had to remove nozzle again to put drill bit into nozzle end directly to completely remove filament, then pushed nozzle cleaner into it to make sure the tip was clean.
10) Replace nozzle n tighten.
11) Place heater and the sensor into their original locations, and put metal sleeve over them. Replace Cover over hotend,
12) Reinstall connectors to hotend using tweezers or pliers, and install screws.
13) Replace fan cover.

Here is a short vid of the hotend teardown if needed.

Thanks for this post, Joe. It will come in handy if/when my Carbon gets a clog (or my daughter's if she takes it.)

Well, I got an app called OctoApp from the Android store, IOS, no idea. There is an official app from Elegoo, Elegoo Matrix, but when I tried it, no Centauri Carbon 1, support, but I did try this app and it does work on mine from on my network. Can it go online, off my Network? I think so, NO clue on how that's be done.  Now I did notice that the app couldn't give perfict control. Was a few hickups that made function not totally work, but overall, did work.
