FEP Clean button

Hello, I would like to add a button that allows user to clean the Fep in this way:
open shutter with blank image
turn on led
set timer of X secs
turn off led
close shutter

After that, in order to a timer compatible with the resin used for the process, the user can manually pick the layer of resin hardened and throw it, then the fep in the opened screen location is completely clean and user won't have to mix and search into the resin container looking for possible hardened resin pieces that would break the lcd pannel on starting a print
Now with Gcode it is possible to turn on Led and set the plate on a neutral position so it doesn't touch the resin during the cleaning process
And then, is it possible to set that button with a command to open shutter like in screen test page?

Thank you, hope Shanin will help us

Re: FEP Clean button

You can use custom button support to handle the senario.

Re: FEP Clean button

Thank you for the reply, but the real question is: what command opens the shutter?
Thank you again

Re: FEP Clean button

You can use the G code to open the shutter. Same Gcode you use will printing. Probably something like M280.

Re: FEP Clean button

Ok thank you, but unfortunately I'm stuck on the problem because my RAMPS firmware doesn't communicate with the lcd pannel, then I can't use a GCODE to open the display
I was looking for something like a command which sends on HDMI the blank image
Maybe I'm stuck on a problem that doesn't exist or something that can't be done in the way I asked
If you have some other advices, I will appreciate, I also think it could be a grat feature to add on nanodlp
