This method does not require Pronterface, it can only be done with the printer. Tutorial made by @Matosantos and @davidtgbe
1º- We raise the Z axis, from the menu Movement / Move axes / Move Z. We raise it a little.
2º- Preheat in PLA mode, from the Temperature / Precal menu. PLA. We wait for it to reach temperature.
3º- Now we are going to add an offset to the Z to later adjust it, for this we go to the menu Movement / Leveling Bed / Offset. Probe Z and we put a value of -3.00
4º- We proceed to make a home, from the menu Movement / Bring to the origin.
5º- Now we return to the menu Movement / Move axes / Move Z, we proceed with the important step, we will need a paper of 80 gr / m2 (which is a tenth of a millimeter) very typical in a Din A4 . We place this under the nozzle, lower the Z axis and move the paper until we notice a slight friction.
6º- After carrying out the previous step, we will have on the screen the necessary offset behind home to bed "this is the necessary height that the Z axis must lower to start printing" which must be left indicated in the probe offset Z, so we return to the menu Movement / Leveling Bed / Def. Probe Z I will introduce the value it gave us, in my case it was -1.80
7º- At the end of all this process, remember to save in eeprom otherwise all this will not have been of any use, for this we go to the menu Movement / Leveling Bed / Save EEPROM.
