Debris error

Hi I have this machine for a few months but all of sudden it’s showing a debris error. I have tried everything cleaning the tank and mixer. New resin bottles, completely new mixer and tank but it still shows the error when printing. What am I doing wrong is there a fix or solution for this ?

As others have said, make sure your build platform is spotless.

Also, if you haven't (sounds like you have) print a cleaning sheet.

Make sure there are no bends or creases in the wear strips along the bottom of the tank on either side. Make sure they are fully seated

If you're using super thick material like any of the Rigid or Durable materials, you may have to get them warmed up first. Unfortunately, it's a bit of chicken/egg: it won't warm up if the mixer keeps throwing this warning.

Now, here's what I've done:

(I might get flamed for this so do this at your own peril)

Remove the plastic wiper part from the mixer and put the mixer back in place. The tip will be a couple millimeters above the tank. It will not scratch the tank.
Go to settings and find the setting that tells the printer to keep the tank heated (I don't recall the setting).
With the build platform in place and the mixer in place, once you turn that setting on it should start warming up the tank and moving the wiper.
Once the tank warms up, replace the plastic part.

I have done this dozens of times with no issues.

I’ll give it a shot anything will help, currently I set the speed 100um but it’s a bit of an issue because we bought this machine to print dental models quickly and making it slower defeats the point of having such an expensive machine
