Finished everything up assembly-wise. Still lots of tuning to do, but I'd say this first print looks phenomenal for not having done any tuning other than Klicky+calibrate_z

Two different problems. First with y endstop, and not really an issue with the endstop, more the cables. They keep wiggling out of the nook you're supposed to stuff them into, and that causes them to get pinched when homing. The cable is just thick enough that it prevents the endstop from triggering.
The other is Klicky, I get wildly different readings to the point where it just gives up because the tolerance was exceeded too many times. I've checked for loose screws, belt tension, etc., can't find anything obvious. I've basically given up on Klicky and ordered a Klicky PCB kit, hopefully that will fix it.
That's my guess with the 3kg, too. Probably need a holder with bearings. I plan on printing this holder (https://www.printables.com/model/513779-voron-horizontal-filament-spool-holder-w-608-beari) because I need something a little more forward based, I'll let you know how it goes.
On the cable, have you considered hot glue? Most of it has a melting point well above 100c, so it should be fine in chamber. Especially if all it's doing is keeping some wires in place. I'm using a PCB xy endstop, so I don't have a lot of advice to give here :(
On klicky, I've had quad gantry level fail a few times as you've described, but it was always a mechanical issue. The first go round I didn't attempt to manually level after assembly and I guess it was too far out of level. I manually leveled somewhat square to the frame and it succeeded on the second attempt. The other times it failed were when I didn't have the ptfe tube installed and the spool fell off its holder and caused misstepping. Have you ever had a successful level?
Finally, on the spool holder. I am using a holder with bearing, but it was designed to sit on top of an I3 clone. There's not really a spot for it on the voron, so it's currently sitting on my desk. I finally figured out how to get the ptfe tube to feed from it, which has helped. The thing I'm running into is that the polymaker 3 kg spools are too wide for the holder, causing friction between the spool and the bolder itself. I've run a couple of other companies 3 kg spools on this holder before and it was never a problem. Then again, none of them were this wide. I'll have to measure the spool to see if it fits this holder.
I have not, what a marvelous idea! Thanks!
With regard to Klicky, yup, I can get it to go through the whole QGL/bed mesh/Z-calibration process and get off a print I'd estimate about 50% of the time. It's mostly just consistency. I can probably increase the tolerances in printer.cfg, but I figure the defaults are what they are for a reason. I had trouble with assembling Klicky due to tolerances of the printed parts, and some of my magnets weren't perfectly flush. I suspect (hope) this is causing some wobbles in the probe itself.
No problem!
I wouldn't increase tolerances, at least not yet. Maybe reprint the parts that deal with the magnetic interface on your voron? I've been reprinting the odd part as I get my printer further along and print quality improves. Another thing to look at could be magnet strength. I bought a bunch of "ultra strong" 6mm x 3mm neo magnets on Amazon for my panel mounts. They're strong enough for the job, but they're nowhere near as strong as the magnets west 3D included in my printer kit.
