Printer Creality CR-6 SE, Motherboard: CR-ERA v1.1.0.3.
Motherboard and screen running code from CF6.1.1-Final-cr6-se-v4.5.3+v1.1.0.3ERA-mb-2024-12-16.zip.

For testing purposes I need to send commands to the printer. To set home I issue G28 or G28 X0 Y0.
With both commands the printer starts to heat up bed and hotend totally unnecessary.
How can I home the printer without the heating?

How do you send the command to the printer? A simple G28 shouldn’t result in heating up hotend or bed!

Yes and no. G28 X0 Y0 switches to a heating-up window for some seconds then revert back to normal.
The community firmware seems a bit sloppy. Rough-and-ready / quick and dirty programming.
