      Is it in the belts or stepper motor?

      @norder Good Idea, I'll double check that this weekend, it's the same for each tower, there's a flat on the motor shafts and I have 2 screws on the pulleys, so it's probably not loose. Admittedly not the same as definitely not lose, and I've gone down rabbit holes overlooking simpler things than that.

      Extruder cable shielding improved surface finish (slightly).

      So i couldn't recreate the issue with another cable..Frustrating when trying to show shielding fixed the issue, but I'm still confident that was what helped...mostly. Still, I had another test print showing what i have moved away from when EMF was an issue regardless of the solution ( cable pathing or shielding). I adjusted contrast so the visibility was clear even if the colors are looking a little artificial. The surface issue was apparent in any print with the outer layer lower than 60mm/s.

      turns out that the issue was running two fans off the same cable right up to their own leads.

      Thank you for sharing your experience, this was an interesting report!

      @owend it's the inner parentheses that are redundant.

      @lord-binky said in Pulley quality tests?:

      they had sections that when moving set calipers along the ID the calipers would catch near the flanges

      Same experience here. It was a bit maddening at the time actually. I still have a sack of pulleys I'm never going to use after trying to find a few good ones. I wish I had the good sense then to have just got good ones off the bat and moved on. 🙂

      @zapta said in My tuned tmc2660 settings:

      @wilriker, I still don't get it. 😉

      If ch1 is the current through a coil, why there are two yellow lines and what are all those yellow dots? The current through a coil cannot change in zero time.

      First of all I am not that skilled in o-scope usage but here is my interpretation: they have overlayed two passes so you can see the waveform better. Also CH1 and CH2 are voltages not current though I think this does not matter much.

      The dots I have no real clue what they mean. I would think of noise or they are the actual sampled values used to reconstruct the displayed waveform. From the screenshot you can tell that they used a Rhode & Schwarz HMO3524 MSO. No longer available but looking at the specs that's a pretty expensive piece of gear. So this might have all sorts of math and black-magic available not found on average hobbyist scopes.
