Interesting results, but why are you investigating this point?Quote
Mr.Lupastr
Black colour strong absorbing IR radiation, thereby IR sensor may have very small sensitivity.
Spacing between IR probe and Lego has been cca 3mm.
Here are results:
colour: G31 code:
Gray 203
Yellow 560
Black 33
Blue 440
Red 432
White 692

Yes, many other people have also found it necessary to stick some reflective tape or some white paint on the X homing tab. Also, X homing may not work if the IR sensor is close to the bed because there is enough reflection from the glass to make the sensor think it is over the homing tab. The updated X homing code first raises the head by 5mm before homing.Quote

My report is for those, which experimenting with different bed colours. As well as, when anybody will build ORMEROD from black filament is necessary to sign (mark)
home point X-axis - for example white.
