As of todays update they have a warning pops up in Bambu studio about the brittleness of the CF filaments before you print. PLA CF definitely sounds alot more grindy going through the AMS then the PLA or PLA support materials.
I personally donât bother with support filament as it is not necessary. I do supports with the print filament being used. In general I was not a fan of supports at all until I switch to tree supports. I use auto, change it to tree slim, and 30 degrees as requirement for support angle. Totally changed it all for me. Far easier to remove, they fall right off and adds drastically less time this way
@TinWhisperer - You could have used either the black or green for the support. The settings leave a good interference layer that it pops off easy. I donâs use support filament on any of my prints, just whatever happens to be in the printer when I am running.
The added time in your print is all filament changes. You can shorten that up a little in the flushing volumes on the left panel. I looked at the poop that it was spitting out and I easily cut 2/3 off the total. White is the tricky one. Usually takes a little more than the other colors to not show the bleed, but still only 1/3 of the OE settings.
You can also reduce the size of the purge block and click âFlush into infill and supportsâ. Also you can use PETG for PLA as support and vise versa. problem being is the PETG needs a higher hot end temp, but it works.
Innovation is working to our favor. There are a lot of ideas out there that people are developing to make multi color prints faster. I personally am holding out for a RBG or a CMYK printer - commercially available, not a hack - that blends the filament for the color.
Can lidâŚFirst multiple color print. Going to be a stocking stuffer for one of the boys. My tiny bed slinger is going to be working 24/7 the next few weeks. I do get to hit the workshop tomorrow and play with some metal.
Well mine multi colour failed. It was just printing into midair but throwing no errors. The internet says thatâs either a nozzle or an extruder clog. Going to watch some videos on how to fix that up and try again. Likely a chunk of PLA-CF in there?
Lol. Not sure if Knick is really trying to help you or not. Obviously you are both forgetting that Mrs. 72Pony put a spending freeze on Erik until the new house is built!
It was just going through the motions. It ended up being the PLA support stuck in the hot end. I put a new hot end in because I could not find a pin small enough to push it and lost the pin that came with the kit.
After the switching the hot end I printed this fidget toy which printed great.
Now i am brave enough to try the same print from yesterday?
You could have tried a hot pull. I donât know the specific instructions but basically you are manually heating the hotend while on the printer to 220*c then take a stick of filament and manually push it in the hot end, wait a couple seconds, then pull it out.
There is a procedure for disabling the extruder drive. BL Forum has it somewhere, and I am sure the BL Wiki pages has it.
@gregmanz not necessary until you need support in a volume that you cannot access. Water dissolvable support material is awesome, if you have a dual extruder or multi filament system. The purge process (time) of the latter would make me opt for a dual nozzle system, not to mention the bambu âfilament poopsâ waste.
