Quick microstepping configuration question.
Stupid simple question, this is my code.
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
I would like to configure E to 32 microstepping no interpolation, I see ( I ) means interpolation, If 1 means all how do I deselect E but keep the others on?

There is no issue running interpolation at 32X correct? This is a Cartesian and is far from computationally demanding.
I'm getting a .9 stepper soon (direct hobbed) and will be going back to 16X, but I'm just trying to see what it does.
On the Duet Ethernet/WiFi, interpolation only works at x16. You can ask for interpolation at other microstepping settings, but it will be ignored.
On the Duet Maestro, interpolation works at all microstepping settings.
Cool, thanks, so technically I can just change E on that one line of code and all is well?
The second you answered me, the mail truck just delivered my new stepper, go figure! E3D doesn't grind a flat in their shafts!?
Thanks, I will try posting results 16X 32X 1.8 deg, and 16X .9 deg.
So I did the tests, need to take some pics still, but;
1.8 16x interpolation- good results some minor banding when shining light above it- naked eye it looks great.
1.8 32X no interpolation- OK results, fares worse than 16X, looks like a normal ramps board printed it.
.9 16X interpolation- best results so far, only slightly better than 16X 1.8.
I will say with the .9 stepper cranked to 1.4A (max 1.7) it gets pretty noisy on the retract/prime, but 1A exhibits skipped steps.
currently adjusting steps/mm It seems like it extrudes just a tiny bit more when simply doubling the stepps/mm
