VC4 500 IDEX - 125hz Peak
Finished cube, still honing in on proper PA value so some corner bulges.

Got the 0.6 CHT in, max flowrate on this filament (HTPLA+) is 30mm³. Got Orca set to do outside perimeter at max speed (316mm/s @ 5800 accel), and slow down on the inside to maintain minimum layer time. Pretty funny to watch it zip around that outside perimeter.

If the dimensions of the prints in Z are important, you probably want to buy a titanium tube and implement the suggestions you find in that thread.

I would also watch for a few days as others try out the new commissioning steps, maybe they provided the key to tuning these right

Hybrid+CoreXY definitely has the cleaner graphs. I would ask yourself how much that extra toolhead will mean for you, vs being able to print very fast at acceptable quality. Not sure how fast IDEX can go with the noisy shaper graphs

Yeah I didn't see many issues on that front, and they have some software skew correction as well. Print quality at speed was my primary want for this machine, so really went into it wanting a clean shaper model and well defined resonance peak (which IDEX doesn't have)

If you're not too concerned about surface quality, it might be sufficient

It's hard to say now that they are providing new tuning instructions that I haven't had an opportunity to test personally. It will be interesting to see others go through those new steps, and if they improve anything or not

I had bad print quality, but others have had good quality (but they may be printing slower, etc).

I did manage to get some decent ones off IDEX, but it was when I was running belts way too tight. Going up in tightness can eventually clean the graphs up, but we're not sure exactly why (it could be dampening in the system from running things too tight).

the graphs directly above that print are Hybrid+CoreXY with a single toolhead

Hi, this was not an IDEX print. I unIDEX'ed and I am testing Hybrid+CoreXY config. 👍

It looks like Ratrig has dropped an updated commissioning guide now too, with a lot more tuning steps

I've seen three cases now (including mine) where unIDEXing arrived at immediate good results. This kinda rules out a lot of the speculation about frame assembly, zipping up umbilicals, etc etc etc. All we did was take a toolhead off and attach another belt to the toolhead that remains

It's hard to say. Going from IDEX to Hybrid+CoreXY is such a shocking change. It makes me think if the belts were the problem, we'd see similar effects between the two configs

Yes, unIDEXed. Never got close to these on IDEX, except when running belts at tensions that break things
