Hopefully i'm not distracting from main discussion, but i'm having similar issue with .9 degree steppers on a HEVO with titan aero direct drive.

I recently bumped my X/Y steppers to 85% max rating and my printer is crazy noisy now, but my VFA has really gone down.

To verify i'm not just seeing crap, i'm going to run a test again right now with high rating and lower and see if it proves it out... changed so many settings i'm not even sure anymore.

curious if running at 100mm/s keeps the motors out of quiet mode and changes how they algorithm works - as that may explain why super high power ratings may do something similar.

thanks all! got it all figured out. It didn't click that i had it wired in a series with the 2 A:B setup... I put them on 2:4 and i have auto leveling perfection finally! so happy since i'd just done a bunch of motor swaps and new plum connectors for the z rods so it was super easy to get level after fixing this!

Just to update, i swapped out cooling ducts - what a huge difference. I also tossed out this white PLA and used another brand and its now printing perfectly. I had to print the old white much hotter than i thought necessary to avoid jams but in doing so it stressed out a bad cooler. fixed both and happy now

Got my Hypercube Evolution running RRF 3.0RC1 with bltouch, dual z leveling (g29) and so far so good!

took a bit to translate my config over, but i really appreciate the text labels now that i'm seeing them in gcode!

Found out my problem. I noticed one side of my printer was always sagging towards end of print, ran motor unlock and i could rotate left z and feel steps, but right z just spun - i guess my right z motor had failed.

Replaced my right z motor, and now bltouch is happy and i don't have to run g29 between each print... kind of surprised i got the quality i did with that motor having been bad or faulty for so long...

but, i'm back in business... no more crazy drift, nice level bed and great prints again. took the time to move to reprap3 firmware and enjoy it too!

Poked around in a sliced gcode from cura - it passes MIX/MAX as comments in beginning of gcode.

Looking to see if those are values that can be used in start... if not, may be able to write a small plugin that set variables

Is there any guide to figuring out input shaping? I can't really wrap my head around it.

I've got the Duet3d accelerometer connected and lit up and when I make a movement I can move an axis but i'm not sure what to do beyond that and when i think i'm moving multiple axis it just moves on the first and stops so i'm not sure what i'm doing.
