If you're prints aren't sticking to the bed despite having good Z offset calibration, one possibility is that it the print bed surface is dirty. This can be a build up of oil from your skin or surroundings, as well as other debris such as dust. It is a good idea to clean the print surface every now and then to maintain its stickiness.
Avoid using painters tape or glue stick, as they will leave behind excess adhesive on the print bed surface which will prevent your prints from sticking properly.
Step 1 - Clear the print bed
- Clear the print bed of any filament that may be stuck to it.
- Rubbing alcohol will not be able to remove filament that has stuck due to a Z offset calibration that was too low.
Step 2 - Clean the print bed
- Wipe off any dust or other loose debris with a clean cloth.
- Using a clean cloth, apply a small amount of rubbing alcohol and clean all areas of the print bed surface.
Step 3 - Run a test print
- Print a
Cali mouse from the featured models section in BuildBee.
Do not use heavy-duty solvents such as acetone to clean it your print bed surface. You should not use anything stronger than rubbing alcohol.
