ho installato Pronterface e cerco di fargli fare i movimenti così.
poi, se ho capito bene dal manuale, devo sistemare lo z offset
" If everything goes fine, when the nozzle touchesthe paper and a bit resistance could be felt if pulling the paper, itmeans the height is OK. Now, check the value of G1Z#(or directly check the Z#from LCD). #is the actual height value(which theoretically should be zero when nozzle touching the paper). For example, ifZ value on LCD is Z001.2, itmeans that the difference between the actual height and the set height in firmware is 1.2mm, so the height in firmware should be reduced by 1.2mm "
