2.7.3 rc1 XL-IS 5T Hotend temp & bed probe start gcode changed (intentionally?) #12517

Description of the bug

When starting a print with TPU, the extruder leaves dots of filament on the bed because the nozzle temp is preset to the first layer for bed probing. I noticed in the recent 2.7.3 changes that code that appeared that it was supposed to handle it had been removed in the preset that my settings were based on. (5-tool XL-IS 0.4 nozzle). Regardless, I saw this issue before the recent change, and it still seems to be there, vs. having it either use the filament-defined idle temp, as I think the old code was intended to do, or a predefined base temp of 70C, etc.

Project file & How to reproduce

Non-project specific, just using the 5-tool IS preset with the Sainsmart TPU settings.

The recent change only drops the temperature for heat absorbtion phase to prevent oozing during waiting.

MBL is then performed with the same temperatures as before.
