With the latest firmware 1.5.15 come two nice features:
Print hexagon mesh for removing objects on tank surface. In less than 6 minutes it creates even and thin mesh over the print area, you grab one end of the mesh and it peels easily from the bottom, including all parts stuck to the bottom.
Calibration of resin level sensor - very useful feature!
After calibration the printer level sensor becomes more precise and avoids using excessive amount of resin in the tank. In my case, after the calibration the printer used the resin from the tank instead of pouring new resin from cartridge.
