add a wiper to elegoo?

[ele]

Hello, I have an elegoo Mars Pro, and like to add a wiper so that I can wipe the resin vat for each layer. My thoughts are to insert a line or two g-code between each layer, for example, after each Z-axis lifting. In order to do this I will need to 1) insert gcode after each layer; and 2) get a signal (or control) from the motherboard to activate a Ramps/Arduino/actuator.

I was wondering if this is possible to modify the elegoo mars? Thank you!
