Hi Bambu fans,
I would like to have some advice and help in printing wood pla on my Bambu Lab Carbon X1.
I’m trying to print wood pla miniature doors, but i’m still getting blobs on the surface of my doors, therefore looking not nicely:
I had to change my nozzle from 0.4 to 0.6, as the 0.4 nozzle started to get clogged after a while.
So now using the 0.6 nozzle I tried all these setting improvements:
- nozzle from 0.4 to 0.6 (no more clogging for now)
- temperature lower to from 220 - 190C
- max volumetric speed from 12 mm³/s to 8, then 4 mm³/s
- slow down outher and inner wall printing speed from 120mm/s to 60mm/s
- put on ZHOB spriral 0.4mm
- put on detect thin walls
- put on avoid crossing walls (but with standard values 0 mm or %)
- filament in dry holder 20% humidity
even with all these changes I still see blobs on the surface. I did not have this with the 0.4 nozzle configuration running ad standard 0.25mm specs at 200mm/s, but those specs are not even standard in the 0.6 mm nozzle configuration in bambu lab
Any advice to improve the quality on this?
Thank you very mutch

What brand?
Polymaker Polylite Wood PLA is the worst filament I have used so far. I have dried it for over 24 hours, and calibrated and it looks like your examples. It doesn’t even have any wood in it so I’m not sure why a wood-colored PLA would be any different.
Hi, It is resolved.
The main help was to print not at the default speed for a 0.6mm nozle being 120 or even lower I think.
On the contrary, I increased all speed levels to the standard speed of a 0.4mm nozzle (250 mm/s i think). That resolved the issue.
Furthermore, I improved it I hope a bit more with zhob 0.2, not transferring walls 100mm, detecting thing walls and having “dry” filament of 20% RH.
On top of that, i used the new calibration feature to have an accurate K value
The other calibration feature to calibrate flow did not work well on my printer. As I calibrated at 220 the flow calibration. He told me to put the flow factor at 0.71. But when I afterwards printed at 190C (wood), I had way too much undernutrition. So resetting it to 0.98, got the job done.
Finally, it was a day or 2 search, but we got the job done.
Kind regards,
Jan
You need to do a flow calibration with the temp you are planning to print at, I would suggest if you change temp do a new flow calibration. I have found doing a temp tower first helps alot.
