Printer and Slicer

• Slicer: Anycubic Photon Workshop 3.4.2 & Chitubox V2.1

Description of the bug

Exposure setting itself to 0s on printer for all layers following Bottom and Transition (including delay UV light activation during transition). When printing a file, the Bottom 5 layers work properly. When the transition layers start, there is a delay in activating the UV light. When the normal layers begin to print, rather than the UV light staying on for 3.6s, it flickers quickly. This can also be noticed in the slicer when the estimated time of the file drops significantly, in the linked file, original file time from slicer is 4h26m, in the UVTools processed file, with the issues of the exposure resetting to 0s, time is now 3h21m. Attempts to manually change exposure on the printer via the settings fail as it reverts back to 0s for the following layer. Attempts to print without processing in UVTools works successfully. Prints immediately fail after processing through UVTools as there is no signficant exposure.

This was tested and confirmed by turning off all AI settings such as Resin Detect and Intellegent Release, covering the screen with a sheet of paper to protect it from the build plate, and watching the UVLight activating via a side hole where the Vat would sit.

Another issue i had noticed in UV Tools 4.4.3; files would take upwards of 15 minutes to Detect Issues. When i downgraded to UVTools 4.4.2, files returned to the normal approximately 3 minutes. When printing with my previous Mono 2; these issues were not happening, as well as the Computing Issues were only taking 3 minutes.

How to reproduce

Slice File in Anycubic Slicer
Save File to Disk
Open file in UVTools
Compute Issues
Fix Resin Traps
Save File
Load file on printer via either USB or Cloud (tested both)
Print file.

Looks like PerLayerOverride is activated which cause problem in recent models.
In same file you can try to: File - Reset layer properties, Save and try to print again. My bet is that will work as that reset all properties and set flag to off.
