How to set e-step on the Ender-3 V3 KE

I tried contacting support but they stated that you can’t update the e-steps on the Ender-3 V3 KE until it’s open sourced. One, when is it going to be open sourced? Two, what can I do in the mean time to get better prints? I want to stay in the Creality eco system, so Creality Print and using the stock hardware.

Can I add it to a g-code file in the nozzle? Will this give me the desired results for each print I slice?

You can usually amend the flow rate compensation from within the slicer.

Here is a link to the calibration tutorial…
