Error generated at the end of exposure time finder, only when "Pattern Loaded Model" is enabled.
Fine for one off models.

Will need the sliced file and settings used to replicate.
But the problem is related to have more copies than your build plate can have. Try lower the number of copies by reduce the number of tests

Please find attached.
Also, in the fourth picture, you can notice I am scrolled to the very bottom of the Exposure time finder pop-open screen. The Pattern loaded model drop-down is not available.
If I generate the model and then reopen settings, it becomes available like in the fifth picture.
Thank you.

Ah you are doing it wrong...
You must have 1 sliced body, and that file is already full with 8 bodies... That will never work.
Also never call your file R_E_R_F when printing

The section dont show up first because theres no space and UVtools auto hides when is impossible to pattern at least 2 copies

Do the following steps to keep only one object on plate:

  1. Go to layer 0
  2. Hold shift + right click on a white base
  3. Go to tools -> Pixel arithmetic
  4. Select Keep Region and Apply

Then you can use Multiple exposures

Also keep in mind that test will be slow to execute, either wait for next version of UVtools which almost eliminate lifts OR use multiple brightness instead which print all objects at once

v2.14.2
683a6f4 
- **Exposure time finder:**
   - (Add) [ME] Option: 'Use different settings for layers with same Z positioning'
   - (Add) [ME] Option: 'Lift height' for same Z positioned layers
   - (Add) [ME] Option: 'Light-off delay' for same Z positioned layers
   - (Improvement) Auto-detect and optimize the 'multiple exposures' test to decrease the print time, by set a minimal lift to almost none
   - (Improvement) Better information on the thumbnail
   - (Fix) Importing a profile would crash the application
   - (Fix) Error with 'Pattern loaded model' fails when generating more models than build plate can afford (#239)
- **GCode:**
   - (Fix) When the last layer have no lifts and a move to top command is set on end, that value were being set incorrectly as last layer position
   - (Fix) Layer parsing from mm/s to mm/m bad convertion
- (Add) File formats: Setter `SuppressRebuildGCode` to disable or enable the gcode auto rebuild when needed, set this to false to manually write your own gcode
- (Fix) ZCode: Some test files come with layer height of 0mm on a property, in that case lookup layer height on the second property as fallback

Thanks. That worked great. I just assumed it would delete existing and resize to suit.

When using the 'Pattern loaded model' it does exactly that, pattern whatever you have currently loaded. For example you slice a amarelabs tower and use that feature.
