Resin Calibration

[RedDevilLax31]

I don't have it yet but planning on getting a Mars 2 Pro around Christmas time so I have been lurking and planning around it a little. I wanted to be sure to have an exposure test so I went through and edited the model, then processed the ctb file with 010 editor to adjust all needed settings and remove the lifting for the layers after the base layer and should have a 50 micron file for AA 4. Not 100% sure if this works or not but thought I would share it in case its needed. its also set up for the Mars 2 Pro to have .25 second intervals instead of the 1 second in the standard file. I assumed with a exposure time of 2-3 seconds the .25 multiples would be much better than 1 second multiples. If someone wants to test the file feel free and let me know how it works.

sorry wouldn't let me attach the .ctb file, ill port somewhere and provide a link

Forked the GitHub to upload the file there, can be found at https://github.com/RedDevilLax31/resin_x...r_mars_pro

I could not get any of the previous links to work on a relatively new Mars. Starting around eary 2020 they shipped with Firmware v4.3.x and that version does not run the .photon files. 

Therefore, I created a new set of test prints that span exposures from 1 to 20 s in one shot. 

You can find how to use them and extend them at https://github.com/r-a-i/mars-resin-xp-finder

I have purchased the Elegoo Mars 2P this month- great machine! running V4.3.9... Im interested in calibrating various resins prior to printing, so need a good workflow.

The gcode files to put into print mode seem to work ok, but the .cbt file are not valid on this firmware. I have managed to re slice the original file in CHITUBOX following the settings in the readme (attached). I dont know how to create the multiple files using 010 editor - but Im not that bothered as I only want a couple for 50 micron no AI, so I created a single 50 micron file. It only prints the rectangular base without any features. I set the layer height 0.05mm - should this be 1mm as per below.? Im not sure the editor changes this.. 

other than this test it prints fine using the ABS like Elegoo grey Im using. My exposure is ok, and repeatable prints. It mainly for other resins Im about to try..

hardcak, from what I found out you need to go into the file in the 010 editor and run the template, then go in manually and update the settings in each layer created, https://youtu.be/s_NIeiNoKi0?t=204 was a link in one of the github pages for it that sort of shows the process that needs to be used but is a little confusing too because some of the settings in 010 editor are not in the same spots as the video
