and if the printer at least works in hybrid-mode - so be it then.

yeah i think if it boils down to "oh well you need new X-belts. AGAIN." i'd at this point just say f it and convert back to normal corexy/hybrid... idex is not worth it then if we are basically extended beta testers at this point. this is what it feels like for me. no proper guides, no statements from anyone officially involved. starts to feel really really fishy for me.

box trick across the build plate? if you mean print squares/boxes - yes. it's the same everywhere. consistently 0.5 mm off in X

and oh well i thought about un-idexing, just have a good, enclosed printer for ABS and stuff - but on the other hand i bought idex specifically to use some multi-material options (like printing petg with pla-support and such stuff). but it just sucks to have problem after problem with this machine. i tried 2-color-prints in PLA this week - but my toolheads won't align properly. although i get them perfectly aligned in VAOC, once i print, T1 is 0.5 mm off in X. and i have no idea how to fix this.

hm, so maybe i'll re-adjust my motor mounts then, i pushed mine all the way back now. what i also noticed: i tried what mikl told me a few days ago in #ratos-development and plucked the belts while in realtime analysis - i got accurate values, my Y-belts seem to be around 21-22 Nm of tension, my X-belts are somewhere between 17 and 19. but i noticed something strange: i can't get a proper "signal" from the X belt segments that run from the XY-joiner to the front tensioner arms. on both sides. in the live view it just produces a broadband mess of a spectrum, reaching from low 20s all the way up to 120-130 Hz. and on my T1 i clearly hear something ring when i do that, but can't pinpoint where it's coming from - it could be the bearing block.

they SHOULD have designed it with bigger tolerances in mind... on the other hand i'm asking my self, why hasn't this been such a big issue on the old VC3 and VC3.1 - they are basically the same design regarding the belt path design.

yeah i mean... just watch xulkals rant-video about the design. 0.1 mm here, 0.1 mm there... that stuff adds up. and then you get wonky shaper graphs, slapping belts and all those other fun things we have to deal with - especially with the idex-machines.

and there are no guides on how you would adjust the X/Y alignment of the toolheads. my Z offset is perfect :ughcat:

my fear now is that it's still not good enough belt wise and/or still has a mechanical issue somewhere, although the numbers speak against this.

hm.. i'm not sure yet, but it looks like i found the next problem with my machine. can't get T0 and T1 close enough aligned so that there isn't a visible gap in a dual-color print - i did test-squares and this offset-L-piece-thingy, and it looks like my T1 is about 0.5 mm off in X. despite VAOC showing them both bang-on, with good x-offsets (0.04) and so on and even after completely resetting VAOC and endstop-offsets and doing it all again.

almost double the PSD - nice. but graph-wise, sadly not that impressive. so maybe the xy-joiners aren't as big of a deal as we thought.

yeah i'll wait for MRW to finish his stuff and then see how much it would cost me in detail. regarding the chinese parts, i don't know. i've heard that the funssor parts also have tolerance issues sometimes. also i wouldn't expect a future 4.1 upgrade before end of the year, if it's planned.

yeah those will be expensive, even more so if you take the reworked motor assembly parts on top - but i think it's worth it.
