Ok, your bed mesh is OK, a difference of 0.5 is manageable and mine has a similar difference.
I will provide further experience with some examples of yesterday’s prints.
I needed to print some ‘everyday tools’ for my SLA printer and were searching for simple filament for it. I found a view rolls of 10 YEAR OLD PETG with strange colors! I calibrated a print profile for it according to my standard procedure described here in the forum and started a print.
Then I had to print a large part for my friend’s shop and I wanted to use a nice, brand new spool of extrudr XPETG Matte filament for it which I also had to calibrate.
After the calibration I started the print and realized after 20% of the first layer (he stared at lower right corner) that I had some issued with the filament. By the way, it prints on 80° for bed and 2350° for nozzle on my Qidi which I used here as well but the part was too big for the Qidi and that’s why I tried it on K2.
There were two problems: I forgot to clean the plate and the z-offset not good for this PETG (which I had for other ETG already as well).
I changed Z-offset vie fluidd within the print by setting it to 0.015 mm which then worked for the rest of the 1st layer and then the print.
As you see, the rest of the print worked well and just need some cleaning (I like this matte finish PETG which looks like it would be iron, I have also a silver version of it which looks like Aluminum…).
I usually add the different Z-Offset to the filament profile but I found a bug in CP6 (this works in Orca slicer but not in CP6):
I usually put in 'Filament Start G-Code the Z-Offset like SET_GCODE_OFFSET Z=+0.015 MOVE=1 and in Filament End G-Code the SET_GCODE_OFFSET Z=0 MOVE=1 and then the filament will work next time.
But CP6 does not output the Start code, only the end code is in the file!
You still can set it in printer profile but you have switch if on/off depending of your filament or create special profile for this filament!
Anyhow, tried to post it on CP6-Forum as a bug…
