i installed a .2mm full hotend on my P1P the other day. I can’t seem to make it work. When it draws the little purge lines on the plate, they are very choppy and look very thin (vertically). When I print a model, I get grinding and adhesion issues. I also tried printing a large circular line and it’s noticeably thinner/fainter in some parts of the circle.
I’ve tried printing with different filaments and with both the high temp and textured plates. When switching out the plates I do a complete recalibration (level, freq sweep). Both plates have been cleaned, but I have tried glue as well. With a .4mm nozzle, prints are perfect.
I thought maybe it was under extruding and increased the flow. All I ended up with is a thicker grindy line.
Any ideas? Is there something I should be changing when I swap hot ends? I did change to the .2mm nozzle in bambu studio and orca slicer.
On the X1C m, I always set the nozzle diameter both in the slicer and on the printer display. Not sure if that is neccessary but I’d expect calibration settings in the printers config. Only changing it in the slicer does not change the printers steps.
Otherwise, a cold pull may remove any obstruction in the nozzle.
P1P settings are very basic on the printer. No way to change there. Tried a cold pull but no luck. This happened with the very first print with this nozzle, right out of the box.
Ah, bugger. On the X1C, its under Settings → Maintenance.
Maybe @Olias has some advice on underextrusion after auto-calibration with a 0.2mm nozzle on a P1P?
Actually, I just noticed that you can also set the nozzle type and diameter on Bambu Handy.
Settings → Nozzle on the Device page.
That should tell the printer, not the slicer, what is actually installed.
Many thanks @Olias for taking the trouble to make a clear sketch.
Jason did set the diameter on the slicer but still had a grinding noise and underextrusion.
So my thought was that the printer would be using e-steps for a 0.4mm nozzle with a 0.2mm nozzle, immediately overloading. Especially since Jason did not see an improvement after a cold pull which should have taken out potential debris.
Not owning a P1P, I am not so well versed though. With the X1C’s Lidar, extrusion calibration should pick that up and lower the steps even with a wrong nozzle size.
Thank you both for your replies. I got desperate and uninstalled bambu studio and cleared everything I could find related to it. Installed latest version and magically same print on .2mm is coming out perfect. No idea what I might have done in bs to cause it and I guess orca slicer was importing settings from bs.
Should have remebered
