I think that I use all of your advice, but I lack experience, so I can't be as good as you before I get some experience

Holy cow! If you knew how many of my prints I still ruin today, you would speak differently.

Here is the tuning discussion, I used this number for E jerk on purpose
guys are saying that E jerk should be high enough so that it doesn't "cap the X and Y jerk values for a print move"

I am no tuning expert. Despite of my long bowden, I don't even use PA. I'm just printing slowly. But, with respect to your stepper settings, it might be helpful if @Phaedrux could have a quick look. He has a "feeling" (or call it "intuition") for suitable values that I completely lack.

My strategy is "try and fail, but do not stop".

šŸ‘ Thatā€™s the way! With a caveat: to learn from a fail, you must be able to localise its cause. If you operate too many handles at once, this may be difficult (remember the ā€octopussy syndromeā€œ? šŸ˜‰).

The thing that I lack about the DWC is git.
It would be great to have a VCS for configs.

This was my very first thought when I updated my printer with a Duet and converted to RRF. In fact, I grabbed some config.g for my type of printer from the Web. To start with, it didnā€™t even match my RRF version. In the end, I had to spell every single line of it (by the help of the GCode dictionary - thatā€™s how I learnt GCode the hard way. Most of the templateā€™s entries were either idiotic or faulty. It took me three months until I had a functional machine again. TBH, Iā€™m still working on that project - after years. The fun never stops, my journey continues.

In my eyes, it is better to use the RepRapFirmware Configuration Tool as a starting point - see: Configuring RepRapFirmware for your machine. It has some flaws (see your Z values), but IMO itā€™s arguably better than some template ā€from hearsayā€ which could easily turn out to be ā€from hellā€.

that is also how the generator creates a config today

Iā€™m perfectly fine with separate entries for axes and extruders, I just noted that it is different from my settings.
