1.2.6 Bed center

I was having trouble getting the print to start in the center of the bed. Here is how to configure the bed center:

In the printer settings window > size and coordinates >Bed shape > click set.

Size: put in the measured size of the bed.

Origin: This is the distance from the extruder X & Y zero coordinates to the left front edge of the print bed.

My X zero coordinate is left of the actual print bed, which required the X origin number to be negative. So my numbers are:

size: x 240 and y 200

origin: x -40 and y 0

You can set endstop coordinates and/or nozzle offsets in the firmware and/or EEPROM to put the (0,0,0) position at some logical location over the bed. The slicer doesn't care, as long as the firmware and slicer settings are compatible, but it does make for more logical inputs when you're driving the tool head(s) around manually with g-code.

You can use the G92 command to put the 0,0 position anywhere you like. e.g. position the nozzle over the left front corner and send "G92 X0 Y0" and that becomes your origin.
