Klipper Replaces first layer temps with default bed & extruder temps in config file.

[Broadmeadow-Tekton]

I have two identical K1 Maxes, both have their firmware updated to Creality's latest - according to the Wiki's instructions. Both are rooted with the helper script and Mainsail; and I use latest version of Orca - which up until now, all have worked just fine. I do call the 'START_PRINT' macro within Orca, via the printer profile's Machine start G-code.

Can't remember exactly when - maybe it started after the Creality firmware upgrade, but lately on both printers, when I print anything, the first layer bed & extruder temps from the slicer are replaced with what is entered into 'printer_params.cfg.default_bed_temp' and 'printer_params.cfg.default.extruder_temp'. This is only for the first layer, starting on the second layer, the temps follow the slicer's settings fine. It seems to me something on the printer is intercepting the print file's first layer temps and replacing them with the default temps listed above, and when layer two starts, the temps called out from the print file resume.

I find it hard to accept I am the only one experiencing this, so maybe there a setting which needs changing with the latest firmware update I am not aware of yet? The helper script has been unchanged since June 2024 as far as I can see, so other than the printer's firmware interacting with the START_PRINT macro somehow, I'm now sure why this is happening.

Thoughts or ideas?
