Clicking stepper motor.
After doing some calibrations for a bit. Printer has probably only been in motion for less than an hour going through the commissioning guide steps. It started up while I was doing my bed mesh and is very consistent. I’ll post it driving itself as well as me isolating it and driving it manually. Already emailed sales but maybe this can be fixed. Not sure…

did u check that it is not the external bearing?
Your not the only person who has had this but I can't remember who it was from the early birds that did and it's not a bearing it was the stepper
Then I guess there is no reason to check 🙂
I isolated each of the pulleys. Sound only shows up on the stepper motor like in the first video of me manually moving it. 😔 Looks like I get to take that stack apart again. Hopefully ratrig can get me a new one out soon. I think I remember the video @Samus VC400 - Minion is talking about. Sounds exactly like it. Not sure if they found out it was the stepper or the carriage but that consistent clicking is the bearing skipping or something I think.

Found the guy who had the same sound.
Ok, I was actually thinking of the bearing that the tip of the axle goes through. But you'll probably see once you disassemble the stack.
Yeah looks like he managed to fix his. I’ll check it out tonight. Hopefully it’s the same deal going on.
Glad that helped sorry I didn't have time to look for it was on my way into work
No problem. Thanks for the responses @Samus VC400 - Minion @mazas
Yup belts too tight.
Did so once you loosened them the clicking stopped?
Pretty much. Loosed them then moved the toolhead around for a bit. Took it a sec, I think it kinda faded down. Idk, I was doing a lot of crap with it lol. Now trying to get this bed mesh under 0.2mm… been a chore..
Check with a reliable straight edge. I spent some time trying to get below 0.1, before I realized it is the bed, not my frame :).
Yeah I’ve tried literally everything. I think it’s the bed at this point. Can’t get below 0.27 or so. Need to find a long enough straight edge somewhere. If I pull the back left down like it shows, the back right then needs to go down... I can go back and forth between the two and nothing changes. What value did you end up with?
It was 115um in the end
What does your map look like?
I had both of the back corners making a dip downwards. Luckily I had an almost usable straight edge, i.e. one that has a specified flatness of <50um
Or ”straightness”..?
And I remember seeing that the spec for the bed is <100um, so something close to 200 might be acceptable. 270 sounds a bit on the high side, but perhaps some could be caused just by the gantry? In which case you might be able to straighten that part out of the equation.
I will show you my last two when i get home. I picked up a machinist caliper from work thats about 600mm or so, i think it should be straight enought to test my bed.
My last two tests were me lowering back left then lowering back right on the next one. Tried pretty much everything I can think of but maybe your experience can help me out. Much appreciated.
Huh, well after sitting for a day I got the best one I've seen yet. 0.24mm not amazing comparatively to others but it's the best I've gotten yet on my machine.
