Hello, i have an Ortur Laser Master 2 and it works great. The only problem is that sometimes I press the fire button to set the origin of my work and suddenly the laser doesnt move anymore, in that moment i cant do anything (Start engraving, stop, move, etc) One thing i have noticed is that whenever this problem happens the Lasr Window shows the Word “Busy”, i don´t know how or why… it just shows. Someone help me please. (I don´t know if it has to do with the fact that i am still on my trial days…)
