This platemaker frame start working but is imposible to open his motherboard programme, because the touch button damaged, and you can not do the funtion uv expose. So if someone want to buy have three options: First to use it for another same platemaker machine as spare parts because is very difficult to find it. Second to use it as plag and play exposure, this mean electical modification to cancel motherboard programme pls. Third to repair the motherboard programme and find new touch button, this mean very well knowledge of elecronics and plenty of time to do this.
