Hello, it is recommended to check whether there is a problem with the sliced picture. If not, it may be a problem with the resin setting or the machine itself.
but it was not the sliced picture and not the resin settings / eposure times.
I found that the LCD-Paneel has grey circels on the mirrored backside ( see foto ), these circels make black holes on the LCD-Screen while printing. I tested this by printing for some seconds whitout the resin tank. So I disassembeld the LCD-Panel to make this foto for you. What now ?
