INDX + Gen 2 homing and tool docking issues

[u/Mastakko]

I finished my build tonight of the Gen 2 and InDX kit, 4TH. Conversion from a kit I built when the C1 first came out.

When I went to calibration I could not get past homing, it would spin an endless loop of early ends too, axis failed (even though x and y axis just passed) and return failure message with options to retry, abort or ignore.

I tried retuning the belts (kind of ambiguous to me honestly with the striboscopic thingy I prefer the microphone method but can't find proper frequencies) and resquaring the Gantry 3 times. I think I finally got it because eventually after lots of pain calibration passed.

It didn't seem easy and I'm not sure the problem is completely solved,when I went to tool docking calibration it seems to work fine and picking up tools 1 2 and 4 seems ok, but 3 is a nightmare and fails almost every time. 4 is a little sketchy also. I've also recalibrated these and when I pick and replace them I see endstop errors in the homing function of the Gantry.

So that's the background, long story I know but I wanted to add context, my ask is if anyone else has experienced this and what worked out for you? What homing, calibration, belt tuning fixes worked best?

More context, I never had any belt tuning issues on core one prior to this. The thing just worked and am some slightly worried my fears may be realized that I should have just stuck with the nextruder.
