Floor of box not flat one side

I printed this tray using polymaker asa. Job did not warp. The bottom of the tray is good and flat but the inside is not. What could cause this?

Hi @CQAdam,

 

This seems to be caused by "old" remains on the heat bed and -it is amazing that your printer did not fails due to this..

If you look closely at the inside surface and compare with the outside -it is easy to see.

I'm using a scrape for cleaning windows after painting, to clean/removing this stuff from the bed. This works very well.

Now and then, you'll also need to wash with mild lukewarm soap water and remember to rinse thoroughly with clean warm water(50 deg. C). You can also use alcohol to remove this finger marks (oil) etc.

So, in order to avoid build up like this, we must make sure that the bed is clean, -my best advice here.

 

Good Luck

Thanks
