first layer problems after upgrade to MK3S
I succesfully upgraded my MK3 to MK3S. Compliments to the Prusa team for the clear instructions!
als the first layer calibration ended without problems and a nice result.
When I switched to regular printing again theproblem with the first layer occurred. The calibration layer was exactly 0.2 mm with excellent adhesian between the layers. After that I printed a 50x50 mm single layer square. The thickness here was 0.28 mm with bad adhesion. The result is also transparent.
It seems as if the calibration is not transferred to my prints.
See attached image. What is wrong or do I wrong?
Hope someone can help me
RE: first layer problems after upgrade to MK3S
Make a first layer and let us see a good picture.
If you can see through the lines it is to high, or not enough filament is coming out of extruder.
A new sheet will stick less then a used one.
PLA sticks more difficult on a powder coated sheet. Is still possible settings need to be more preciese.
This how I work on a pei sheet(there are always exceptions):
Most important to 3d printing is:
1. 3d print will never be like start and i have the print, there will always be problems!!!!!!
2. A clean sheet, use dish soap, then you can print on it. A few prints you can use alcohol, then again dish soap,
big flat models and models with small footprint on sheet- use glue stick(and not every glue stick is the same,
use one that makes a thin layer), and big flat models and small footprint, use a big brim attach to model so footprint is bigger.
Petg sticks to much on the pei sheet, use window cleaner, this leaves a layer on the bed, so it does not stick to much.
3. To get it stick very good, a 100% first layer is very important, see youtube for movie on this.
Every new print watch the first layer, and look if it is 100%, this will also prevent a big ball of filament on your nozzle wen model let loose during printing.
Extra: (normally not needed).
First layer, print hotter.
First layer slower.
Bed more heat.
Most problems are first layer to get this 100%, and bed not clean.
Bad filament is possible, or filament with water inside.
Move extruder to the top and extrude filament, it should go straight down(if not, nozzle possible blocked),
it should be thick enough(if not, nozzle possible blocked, or partial blocked), (do a cold pull),
if Bubbling during extrusion then it has to much water inside.
Check after the first layer is ready, then you see if it sticking enough, and not releasing and sticking to the nozzle.
If you see white spots like a bubble on the bed, then filament is releasing from bed.
Also no gabs between lines should be visible.
Use 7x7 calibration for first layer, see settings in the printer.
Search for " 3D printer first layer problem Calibration process" on youtube, movie on first layer calibration, with a good zoom in.

Perhaps you should read these pages. I think afterwards it should work with the z-first layer calibration:
Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.
