Citat: stipe  u 19.09.2023. u 21:30:27 satiIma teflon na osovinici, a sa druge strane ona 4 kuglicna lezaja. Prevelik je otpor na spojki i ona se uvija. Ako malo popustim pritisak, cijev mi klizi.

E onda neznam. Kompenzacija backlasha neće tu puno pomoći jer ne vjerujem da se svaki puta isto odradi to uvijanje.
Moraš na neki način podesiti da to ide lakše ako hoćeš autofocus.

Moraju biti mali kuglicni lezajevi na osovinici fokusera kako bi to moglo ici glatko.

Evo napokon test od veceras! *hopla*

Ponovio par puta i test je bio isti! *hopla*

Potvrdio i g. Bahtin *zubko*

Sad da li ce tako htjeti raditi na terenu, veliko je pitanje... :-D

Ako su postavke ok i ako radi kako treba, kažeš da si odradio par puta testove i da je ok onda nebi trebalo više zezati
