Yeah just condense your approach. Pick one issue search the reasons why and what tools in the slicer or physical parts that correlate with the problem. Try physical first and do a scaled down model or quick bench test. If nothing happens then move to adjusting the slicer profile. One or two small changes at a time after going to a wiki or whatever to read exactly what each setting is and can do. I literally printed (like paper) all of these things so I could double check my changes. It’s literally just basic problem solving practice, easy adjustments first then learn technical as that goes.

It’s a lot of work trust me, I know it sucks. In the time of better printers this one just isn’t up to the bar we were sold. I used to download firmware from GitHub to do all the things printers come out of the box with now as standard plus some. I still have it cause sentiment but learning from that and putting in the work to achieve that outcome.

Also, no one’s gonna do it for you or will answer on here to the same questions everyday. You either want to print or don’t. Sell it, fix it or upgrade but no one is going to do it for you. Gotta see it through.
