so in that way the problem is solved even if I reboot or plug off the printer?
How much thick is a quarter? (I'm not in US )Maybe I can use the puck instead of the quarter?
I used the puck instead of the quarter and now is printing the holder over the the Fleks plate (held by tape for now)...
My fleks just arrived, seems to be absolutely flat without any warps or something like that. Will test it this evening
