Just did a Boot to 3D Calibration CAN sniff. https://pastebin.com/p0Pka2gz all the Data is in Hex
IDs 0-20 are Marlin specific and only set to 0 at Homing start.
0x16 looks like a Info request or a Heartbeat as its regular 500ms intervalls
0x615 Probe 3D module
0x616 is the Filament sensor (which is currently 0x01 as it has Filament loaded)
0x617 Target Nozzletemp (Bytes 0,1 report current x10, 2 is a spacer and 3 is the target Temp)
0x60D is Limitswitch Z axis
0x600 is Limitswitch X Axis
0x605 is Limitswitch Y Axis
Im not sure which limitswitch counts for the Dual Modules, i guess first reported?
