It's normal for the MCU and ESP to be slightly warm. The blue LED on the ESP won't turn on unless the MCU initialises it.

I suggest you try erasing and reloading the firmware in case the MCU is still OK. See https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3.

The M557 XY coordinates are machine coordinates.

The height map is an additional Z offset, so the Z coordinates in it belong to no particular coordinate system. The XY coordinates are machine coordinates.

Why do you think this is a bug?

@marius-h did you get it working?
