Is there a way to figure out firmware parameters on marlin firmware?

Software / Firmware General

Greetings All,

I am currently running a MPCNC with a Rambo 1.4 board. I don’t recall the marlin firmware version. I want to add some additional functionality like mechanical end stops and a relay to start the router at the start of a program and turn off at the end. As long as I am modifying firmware, i might as well upgrade marlin to the most recent release.
Looking around on the firmware configuration page, i see that I may need to do some tuning on the motors. I bought my unit 2nd hand (i may have been the third owner of the unit) and I can’t talk with the person who built the MPCNC originally. Is there a way I can figure out what tuning parameters may or may not have been configured when the controller was flashed originally? Is there already a post that explains that? I wasn’t able to find my answers on the forum but I may not have been typing the right questions.

Thank you for the help, always appreciated!

You may be able to read out from the eeprom any modifiable and saved settings. I don’t know of a way to “reverse engineer” the compiled settings out from the compiled binary. (Doesn’t mean it can’t be done, just means I don’t know how).

I always used to go back to https://marlinfw.org/ for guidance when I run across these sorts of questions but it’s been a while since I’ve run Marlin on any of my machines.

did you ask m503 and m115 with pronterface?
m503 = Print Current Settings

m115 = Firmware Info – Reports version, features
