   - 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.

     * My Screen showed 1.6mm, I perfonally found I needed to add 0.2mm onto this, so my final value became -1.8     * My Screen showed 1.6mm, I perfonally found I needed to add 0.2mm onto this, so my final value became -1.8
-     * If you want to lower the head by 0.02mm then you would issue the command "M851 Z-1-8" or to raise it by 0.02mm, its "M851 Z-1.4". Yes, INCREASING the number LOWERS the head, backwards to what you'd think logically, but were using a - sign before it, so the logic is correct. Issue a M500 command to save this value in the EEPROM once you've figured out what it is. In my case, a value of -1.80 works well.\\+     * If you want to lower the head by 0.02mm then you would issue the command "M851 Z-1.80" or to raise it by 0.02mm, its "M851 Z-1.4".

   - 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.\\
