Printing Speed too fast for First Layer? No Adhesion?
Hi folks
I have some Issues that the first layer does not stick properly and then it fails. Even the brim does not stick well and goes into the Object, also a bit much oozing...
Can you print with a max speed of 200mm/s? Also the solid Infill 85 mms and outer perimeter goes far too fast for a good result.
I orderer now some 3DLac now, for spraying on the bed (Altought Joe thinks it's not nesscessary)
I reduced the speed to 80%, by some codes it's better, but not solved
Have no time for all the failures all the time...
RE: Printing Speed too fast for First Layer? No Adhesion?
You did not provide very much information here. What type of filament are you trying to print?
Adhesion problems are 99% related to non optimal first layer heigt configuration and/or unclean printbed. Make sure to clean the print bed with soap and water every now and then and try to not touch it without gloves.

I wanted to print normal PLA...
What is a optimal first layer height config? I Always use 0.2 (like default) and 20% Speed

Sorry my reply was probably missleading. I meant Z calibration to get a proper 1st layer. This is essential for all prints to be successfull.
I suggest to follow this guide:

Hot Water wash: often, as needed, and after any of the following
(not recommended for daily use on Powder Coated sheets)
- Handle the bed only by the edges.
- Wash the bed in hot water, use a fresh paper towel as a wash cloth, with a few drops of plain dish soap (Dawn, unscented, no anti-bacterial, etc.).
- Rinse well in hot water - if you have very soft water, rinse a bit longer.
- Dry the bed with a fresh paper towel.
- Handle the bed only by the edges.
- Place bed on printer.
Alcohol wash: every few prints as needed
- Gloves recommended.
- Once in a while, an alcohol rinse is helpful to remove PLA residue. It does not remove finger oils well.
- Pour a 5 cm puddle of 91%+ alcohol in the middle of the bed, with clean hands use a fresh paper towel to scrub the bed. Wipe up all the alcohol.
Acetone wash: infrequent as needed
(Not recommended for USE on Powder Coated sheets, but some find it necessary)
- Pour a 2 cm puddle of acetone on the bed, scrub it around with a fresh paper towel. It will evaporate fast as you clean. This step removes PEI oxides that form over time and with heat, and improves PLA adhesion to a like new state.
Streak test: when contamination is suspected
- With a fresh piece of paper towel, and very clean fingers, dampen the towel with 91%+ alcohol, and wipe the bed side to side moving back to front, like you're painting it with alcohol. The alcohol should be thin enough on the towel it quickly evaporates from the bed. If you see any streaks, the bed is dirty and needs a wash.

Please post a brand, temp settings, speed settings (in mm/s) you're using.
