Hi Everyone,
I received my Elegoo Mars a couple of days ago. I am new to resin 3D printing, and while looking for calibration test pieces, I also stumbled upon https://github.com/altLab/photon-resin-calibration and thought it would be a good idea to have something equivalent for the Elegoo Mars.
After reading somewhere that the Elegoo Mars firmware does print .photon files I had to try it myself and it turns out it does recognize them. So I forked the photon-resin-calibration repo to https://github.com/dxxb/photon-resin-cal...legoo-mars and added an experimental "resin-calibration-setup.gcode" file for the Elegoo Mars. I am not an expert but I believe the first test was a success, pictures attached. The first was taken when the calibration sheet was still attached to the build plate, the second after curing with a brighter paper below it to improve the visibility of some details.
Please read instructions (from https://github.com/dxxb/photon-resin-cal...0a74cdbd75) here:
Note that another fork by toluse (see https://github.com/toluse/photon-resin-calibration) seems to be also working towards the same goal. However, I haven't tried calibration tests from toluse's fork (yet).

Quote: ElegooMars: remove photon test setup/teardown gcode and add experimental Elegoo Mars setup gcode
- Print resin_calibration_setup.gcode to setup the printer for testing.
- Print one or more exposure calibration files without power cycling the printer.
Test settings are not saved to non-volatile memory so power-cycling the printer
restores normal operation. This is intentional.
The first test was successful using:
- Elegoo Mars: "V4.2.20.3_LCDM/1440x2560/F2.9"
- Resin: Elegoo Standard Grey
- Previously saved persistent settings from: "ChiTu Mainboard SpecificationV3.0.9.gcode"
- Test settings from: "resin-calibration-setup.gcode" included in this commit
- Calibration test file: "resin-test-50u.B100.2-20.photon"
