Resonance, spreadCycle and stealthChop

on your corexy design , did you test the motion system before connecting the belts ?
maybe the rails are not 100% parallel .ooooh yeah it took forever to align those rails
in the new motion system I have even more rails. I'm becoming an export at aligning rails!@hackinistrator said in Resonance, spreadCycle and stealthChop:
on your cartesian design , i'm not sure if its a good idea to run the rails unsupported like that .
I dunno, they are pretty hefty rails. I hope they will be fine. If it doesn't work I'll put them on a baker.

this is funny because on my config (core XY tmc2209 all metal frame and parts) i had to force the spreadcycle because stealthchop was noisy at more than 60mm/sec
and what i think is that stealhchop induce some counter force to reduce the sound (and so on a move you don't have a really perfect sinus wave on your motors wires) but the problem is taht they mess together when using a core XY, because both the variations from each motors arrives in the x cage and from my observations this is from the sound comes. for me the stealthchop mess with itself because it's not supposed to work on core XY. and that's why you got wierd noise when moving both motors at the same time and not on diagonals.
and i have to admit i can live woth spread cycle because honnestly the fans are louder, by far.oh and on the BLV mgn FB page when io talk about my problem the first thing people said was "disable stealthchop, it suxx with marlin" as they thought i was on marlin.

that's interesting. just a note though

it's not a noise issue. everything shakes!
but anyway with the new kinematics I solved the issue. Don't tell @dc42 but I also installed klipper on the duetwifi

How does this work, did you replace the Duet's firmware with a dumb version that is controlled by the Klipper SBC?

yes, you have to replace the original firmware with Klipper's. I like RRF "all is Gcode" philosophy, but over all I prefer klipper and I don't think I'll revert back, at least for now.
