Slabý zdroj nebo chyba FW?
Napsal: 17.06.2016 19:17Zdravím vás a žádám o pomoc. Postavil sem si tiskárnu o rozmerech pro tisk 450*450*550 a nevím si rady. Firmware mam Marlin z gmax1.5+ tiskárny a HW: 500w ATX zdroj, Ramps 1.4, arduino mega 2560, motorky (Nema 17, 0.4nm, 1.7A) a drivery A4988, 40w topné těleso, lcd 12864. Problém je ten že když zapnu nahřívání tak se tiskárna začne dokola restartovat a nic se neděje a to stejné u os Y,Z , jak s nimi začnu hejbat tak v nich začne cvakat a když jim přidám trochu proudu na potenciometru, tak se tiskárna restartuje. Prosím o pomoc a děkuji za každou radu.

. Na zdroji při pohybu os sem naměřil 8,5V a při ohřevu se to nedá stihnout, zdroj se ihned restartuje, zítra objednám asi tento
