Bambu 0.6 Nozzle

So I’ve bought a Bambu Labs P1P and have generally been enjoying. Its way faster and more accurate than my Wanhao Duplicator I3. Plus my mods looked like a fire hazard. I’ve had basically zero issues with printing using the 0.4 nozzle.

I switched to the 0.6 since that seems to be what Ryan prints with. I switched the nozzle size on the device tab and the prepare tab to 0.6, chose the bambu PLA matte profile and printed the calilantern. First layer didn’t stay attached; maybe the build plate was dusty. I wiped it off with IPA (not the beer), and tried again with the same results. I slowed down the first layer and it got through about ten layers before detaching again. I could slow down the whole print, but that kind of defeats the purpose.

I’ve tried the flow calibration but all of them detach and slide around so can’t get much good information from it.

Has anybody on here had the same issues? Suggestions on how to go about fixing it?
(And again, 0.4 nozzle size works fine so it seems like a slicer/calibration issue)

That nozzle is significantly larger. Your speed increase is by cubic millimeters, not the speed of the movements. Chances are you will need to move slower, but you will be pumping out much more plastic.

You need to do a max flow test, then take note of your max mm/s^3 input that into the slicer.

Same speed gets you more than twice as much flow. Your layer thickness can be significantly increased. Parts will take about half the time or less.

I don’t personaly own the P1P but an A1, so my advice may not be fully applicable. A couple things you can check besides the things you tried:

check if the printplate is still selected as the correct one, mine changed by accident ones and caused similar issues.

Check if there is enough flow rate, A1 can do flow rate testing automaticly i dont know if the p1p also has this function.

Check some values of the selected 0.6mm profile.

What layer height are you using?

I will start off with the max flow test then. And yeah, by faster, I mean faster sliced time; not faster movements. 0.3 layer height vs 0.2 layer height.

Also check if your part cooling fan is working. I remember a video in which someone mentioned that during a nozzle swap on a p1p, the fan wires come out. And it doesn’t cause any error messages if the fan is not working.

Printing a calilantern with 0.4 nozzle today just to get a benchmark, then will start trouble shooting the 0.6 with the above. Extruder cooling fan is definitely working, I don’t have the general area fan.

Not a Bambu user at all, but since I generally build my printers, I’m always chasing stuff like this down.

It sounds generally like a z-offset problem. If there is a calibration you can run with the 0.6 to recalibrate, it might help. (Not just the mesh level stuff, but actually recalibrating the subsystem.)

Alternatively you might try adjusting for a bit more first layer squish.

If you’re still having problems with this I could send you a 3mf file that works on my printer for your to test out. This could help nail down whether it’s a slicer problem or not.

I am using a Bambu X1C with 0.6/0.8 nozzles and experienced similar issues with Bambu PLA and the cool plate. What did the trick for me was nudging the build plate temperature up to 55℃ and if that didn’t help applying a thin layer of glue (not the liquid type, but for the most part glue wasn’t required anyway). And as always: drying the filament can help a great deal. Best of luck!

I have a three day weekend this week and want to upgrade my LR2 to LR4. I’m going to use the .4 nozzle since I know it works well and then trouble shoot the 0.6 nozzle.

I was thinking the bed temp too. I don’t have an enclosure and the temps in northern indiana are cooling down outside and inside my house. Might be a small part of the issue.

Thanks for the responses, I’ll hopefully get back to this in a few weeks.
