I have Dub Crank and Axs D zero Spider
Have some problems with the chainline
Is the Spider on the photo ok at this position?
The Spider is 2mm out of line

That's person 3 or 4 in this thread (including me).
Safe to say the DUB cranks and 110mm AXS spider isn't a huge success when it comes to chainline. It works, but some frames (rim brakes with a smaller hub width possibly) have more issues than others.
Count me in as person 5. My situation is a bit different though.
I purchased some Red branded D1 cranks in December along with a Sigeyi AXO AXS-4-110 power meter. Magnetic charging as opposed to coin, and a 55 gram weight difference compared to the DFour attracted me to this point (duh, where are posting
). This is a rim brake bike with a 68mm BSA BB.
I paired these with brand new DA 9100 rings and a BB Infinite BSA Dub bottom bracket. BBI's 4.5mm outboard spacer and outer cup creates the same distance/width as the SRAM BSA BB with the 3mm spacer installed. They did their math right. I checked at a local shop who let me compare both with a caliper.
Sigeyi's own chart and a photo or two from customers on their website lead be me to think this would work. Attached a photo of that.
I assumed(like a fool) that the 4-110 version was made as a Dfour equivalent, with chainline maintained for 9100/8000/7000 set ups running the AXS cranks.
I could tell soemthing was off right away because my inner 34 ring was about 3mm or so more outward from the normal distance my Shimano crank and 34T is in relation to my chain catcher. I had to adjust the High Limit quite a bit, and the bike shifts and works fine, but the chainline is not to my liking at all. I know that the attached photo showing the interface between crank and PM spider doesn't seem like a big issue. I think it has to do with offset off the chain ring mounting points as well.
I really only read this thread attentively enough to learn that I was late on getting the Red D1 cranks at the lower price, and didn't realize there were chainline issues for some folks. I am pretty positive Sigeyi used the measurements from the DZero set up and they simply just have different bolt patterns, but the chainline is not changed at all from say 5-110 to 4-110 like the Dfour Dub appears to incorporate.
Gonna see what they say about it. Costly experimentation since now I just have to buy the Dfour anyway. I am going to try and move the DS dub spacer to the NDS, and see if I can fine tune with the chain line with spacers. The thought of it all being "wrong" bothers me though.
Cliffsnotes: Sigeyi AXO AXS-4-110 with Red D1 cranks seems to create the same issue as the Dzero on some rim bikes.
