My problem after updating Bambu Studio to 01.07 and the printer to 01.06 is that I can’t print anything completely because everything is peeling off the PEI table.
All prints are made of PLA or ASA
In addition, the structure that appeared did not quite remind me of the structure from the first prints on PEI. (photos).
At first I thought it was too low a table, then too low flow and now I don’t know.
So far I’ve done:
plate cleaning,
nozzle cleaning,
manual table setting,
calibration,
return to software version 01.05.02.00 and 1.6.2
increase in flow,
increase and decrease of the first layer,
Still nothing. On the engineerig plate, the print sticks to the plate and the print is nice.
On PEI, I managed to make a few prints without the material peeling off, but with the structure from the photo.
Photo: Object on the right - old print,
object on the left - after update.
tell me what do you think when you first saw it? maybe I’m going the wrong way. Below is the last printout. A little better because it didn’t peel off but the lines are still visible on the structure.
I know the photo is a different model but the problem is in every model. As if the record did not give structure. or there was not enough material that did not fit into the board structure. In addition, it must be added that the elements do not stick to the plate.
There are two problems, but only one solution.
Problem 1. - Models do not stick to the PEI board
problem 2. - no structure on the model on the bottom layer
Near the bottom of the ‘Machine start G-code’ is this:
;===== 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{-0.04} ; for Textured PEI Plate
{endif}
You can try to lower the nozzle a little bit by changing the following: G29.1 Z{-0.05} ; for Textured PEI Plate
or -0.06 to press the filament a little more into the plate.
But not to much or the nozzle will scrape the bed.
The PLA is by eSun and it prints nicely on generic PLA profiles.
I mainly use generic profiles.
On PEI it’s 55, I tried to 65 but it doesn’t make much difference.
I’ve done some printing with the same settings. The spell was broken after the software change.
Asking the obvious because no one else has yet. Have you cleaned the print surface? Unlike the other plate materials, a little bit of oil from your skin isn’t visible but it will ruin first-layer adhesion until it’s cleaned. I spray and wipe my textured PEI with IPA from time to time. I’ll only bother with dish soap if I’m going to print ASA and the model looks like it’s going to be a high warp risk.
I’m having the exact same issues with the PEI plate since the upgrade of the slicer + firmware.
I’ve managed to have some successful prints with downgrading the printer firmware to the 05 release, but still getting significantly more failed prints than before
might give the bed adjustment thing a try just be careful and good luck.
