looks at MRW shop well a set costs 25$... the cheapest shipping option is almost that amount on top (USPS international) 23.69$ - and then i don't even know how much tax/customs i have to pay once they are here, as the EU and esp. germany cancelled any form of free imports for private people if it's under amount of X 😂 i guestimate that i would likely have to pay another 25-30$ just in customs/taxes on top. thats almost 80$ or around 75 € just for two metal clamps :kekw:

i'd like these clamps too, sad thing that you can't get them easily in germany

and i wanted the idex specifically to do multi-material-stuff 😄 guess i'll just try and get it "as good as it gets", see how it prints, and go from there.

going to hybrid would suck for me, would mean i'd have to get new belts

ooof. well i re-did the rails (removed old thick grease, added new grease - WD40 specialist white lithium grease) and added the 1mm padding under the bottom steel plates. i have a feeling that this improved things a bit and dropped the noise floor, but i still have to figure out proper belt tension now. and if that isn't working, guess i'll also have another look at my mechanical assembly.

there i noticed that T0 has multiple spikes between 10 and 40 Hz shaking frequency, above 40 you just get a single peak on the frequency you are shaking at, so i think maybe there's the reason why my graphs are so bad, but no idea what that could be. holding the umbilical or cables on the printhead or other stuff around the head doesn't seem to influence those peaks.

maybe some guidance on how to do rough tuning/belt tensioning with the realtime analysis tool would be great, as every shaper run takes some time, even if you only do it on x or y alone.

same. thought maybe my belt on T0 is rubbing/binding somewhere, but that's just when it's super loose - with more tension it runs okay again. no idea what to do. experimented again today, got it at one point where T1 had MZV with 1e3 and a good peak, but broad base, while T0 had two huge peaks, 2HUMP and also 1e3... guess i'll just do it really rough, do the rest of the calibration and then wait for a proper detailed guide on how to do belt tension and IS on idex machines. like this it's too much trial and error for my taste.

i don't think it's anything mechanical because i checked the idlers when i had the gantry out, they roll smooth. rails - maybe a bit rattling (could be that my lubricant i used is a bit too thick) but not binding or sounding "damaged" (but i must be honest, i never had a damaged rail, so i don't know how that would sound, but i'd imagine it would sound horrible - grinding noises and stuff. i don't have that). and frame-wise, the only thing i did at the very begining was adjust one side a bit with slight taps as my bed mesh showed me a high spot in one corner. that's it.

at least knowing that my belts are somewhat equally tensioned would be nice, a proper working IS is just the cherry on top. but like this it's throwing red hering after red hering towards me. i mean i even had the x-gantry out this week because i thought something was wrong. idler-assemblies not properly inserted to the extrusion or something like that. nothing. i pulled both x/dc-belts out to make sure they are both the same length. they are now. i de-racked the gantry a few times, both with belts out and belts in again. it's as square as can be now. i re-tightened all the bolts and screws i could easily acces. i just can't wrap my head around why it won't go over 1e4, and most of the time with only one toolhead, or with completely different shaper algorithms on both toolheads IF they both manage 1e4 with veeeery low tension on all belts - that graph was with what, i believe a little bit over the first marking on that belt tensioning tool you can print? so very very loose, just tight enough that nothing slips off of idlers and pulleys. so from my feeling, too loose. then i went up again and here we are, 1e3 and 2HUMP_EI on both heads...

those are nice. would be so great to have a MRW-reseller here in europe, especially germany. it's not really viable to order anything from mandala because of freight costs, taxes, tariffs etc.. ordering stuff from the US is stupidly expensive right now.

i wonder if the realtime analysis could help with a rough tuning of the belts and then do the finetuning with IS

:kekw: so basically IDEX is trail & error all the way
