- Take the current Z value on the printers LCD screen and negate it. (so a value shown of 1.6 becomes -1.6), this is the offset between your print Nozzle and the sensor height. | - Take the current Z value on the printers LCD screen and negate it.

- Next, do a bed level using the LCD and the print bed levelling knobs so that the bed is as level as you can get it using this method, basically proceed to set the correct 0.2mm layer height pretending as if you don't have an IR sensor.\\ | - Next, do a bed level using the LCD and the print bed levelling knobs so that the bed is as level as you can get it using this method, basically proceed to set the correct 0.2mm layer height pretending as if you don't have an IR sensor.\\ | ||
