Ender 3 Pro - E-steps

Forgive me if this sounds like a noob Question but I’ve been watching tons and tons of videos on how to calibrate your E steps etc. spent a lot of time messing around with different programs to upload it to my EPROM and today I was fiddling with the settings on the printer and noticed there is an E steps setting directly on the printer. Having watched 30 or 40 videos about the saying you couldn’t do that I was perplexed. So I investigated and this function seems to be working and I was able to find a single video on this feature.

anybody else know about this or use this function. Seems to me to be a game changer

You are correct. That setting is available on many printers, especially now that so many printers have 32 bit controllers.
