Hello, I am having a weird issue that I cannot print with my 0.2mm Nozzle anymore. As soon as i change to the 0.2mm Nozzle the Nozzle is scraping on the printbed. Standard Bambu Profiles.
I have enabled Bedleveling, change the Nozzle size in the Printer, washed the Printbed, tryed another slicer (Orca) even tryed a different fillament, not that that would make a difference. No change. As soon as i change to the 0.4mm Nozzle no problems again.
Not new to 3D Printing but new to Bambu Labs Printers, what do I miss here?
It also was very hard to remove the enbedded filament, only overprinting and peeling off with the 0.4mm Nozzle did the trick here.
Its the nozzle audible scraping on the bed. Extruder is skipping steps because the build plate is blocking the filament flow. Thicker layer line settings woun’t cut it here. I also used the standard Layer height, nothing crazy low.
Hey,
I am having the exact same problem:
0.2 Nozzle is scraping while printing the first layer, that layer is hard to remove and looks patchy/too thin like in your picture.
I tried full calibration, washing the plate and drying my filament as well as checking the hot end screws. I also tried a higher first layer height, but nothing works.
The 0.2 nozzle was printing just fine earlier last week.
Meanwhile the 0.4 nozzle is working perfectly fine.
Did you have any success in fixing your situation?
What I did to fix it tempoarly is change the value in the Nozzle settings in BambuStudio.
You go in there search for this passage in “Machine Start G-code” and replace G29.1 Z{-0.02} ; for Textured PEI Plate
with
G29.1 Z{0.12} ; for Textured PEI Plate
or you can try another value, this was the one working for me. Then save under a new name I chose “0.2mm No scraping” And then I also selected Textured PEI Plate instead of smooth plate for the print even when printing on smooth.
Here is the whole passage you have to search for:
;===== for Textured PEI Plate , lower the nozzle as the nozzle was touching topmost of the texture when homing ==
;curr_bed_type={curr_bed_type}
{if curr_bed_type==“Textured PEI Plate”}
G29.1 Z{0.12} ; for Textured PEI Plate
{endif}
But I would love if Bambu would fix this, not sure if they are even reading this forum?
Thanks. Used the edit and now it’s working. This is clearly a Bambu/Slicer issue.
They need to fix this or at least allow us to change it in Slicer settings rather than directly in the G-Code.
THANK YOU! It was driving me crazy that my 0.2 nozzle prints suddenly stopped printing correctly. I thought i had accidentlly changed some setting or something but couldnt find out what. Now it prints perfectly just as before.
I have the same problem and would like to try your solution. However, I’m wondering where you can find the G-code.
I can only find one G-code under the filament settings in the “Advanced” tab. There you have “Filament start G-code” and “Filament end G-code.”
But you’re talking about nozzle settings.
Could someone please tell me where exactly I can find the nozzle settings and the G-code for the change?
I think I’ve finally found it. Bambu Studio 2.0 has been available for a few days now.
The Edit button is only visible when you hover over it. So, you have to hover over the printer (in my case, the Bambu Lab A1) in the top left corner, and then you’ll see the Edit icon. The relevant code can be found there in the “Machine Code” tab.
I hope this helps someone. I’ll test the settings now.
