Reproduction steps

  1. Set "Initial Layer Temperature" to a different value than the regular "Printing Temperature".

  2. Slice a model that has a solid bottom.

  3. Check the G-code or observe the active printing process.

Actual results

The first layer walls are correctly printed at the "Initial Layer Temperature". However, when the printer starts filling in the first layer bottom (skin), the temperature unexpectedly changes to the regular "Printing Temperature". Interestingly, the printing speed for the first layer bottom is correct and matches the "Initial Layer Speed".

Expected results

The entire first layer (both the first layer walls and the first layer skin/bottom) should be printed at the "Initial Layer Temperature".
