Basic Information:
Printer Model: Voron 0.2 S1 rev A (LDO kit)
MCU / Printerboard: Pi 4 / BTT Pico

After I got the printer operational, I tuned the IS according to the recommandations, and I’m fully satisfied (beyond my expectations). It’s been printing parts for a Voron 2.4, but couldn’t resist to the temptation of making some mods on the Zero…
Among others, squash ball feet (it is a bit noisy : prints fast, 10000 mm/s², high currents and spread cycle…)
This printer is always sitting on a 300x300x70 granite plate. Temporary, as it is normally in the workshop, dedicated to blueing (cleaning was a bit of a pain !)…
I did 3 tests.
- the Zero on its standard feet, on the granite
- the zero with its homebrew squash balls feet, and a half full filament spool
- the zero with its homebrew squash balls feet, and no filament spool
IMHO, the results make no sense because we get absolute values, relative to the earth, not no the bed or the frame. (but I have an idea)
The Zero, standard configuration ; looks similar to other printers, even to my homebrew bed slinger… :
The Zero, filament spool and squash balls ; here it becomes funny :
The Zero, squash balls, NO filament spool :
What do you think of such measurement (on my side, I think they have absolutely no value !)
I also have a dual accelerometer, made from a Pico and a pair of ADXL. I was wondering if running the X and Y test with a ADXL attached to the bed (or somewhere else) could be interesting : is it possible to use the csv data and substract them from the normal X and Y data in order to negate the printer moves ? Does this make sense ?
[EDIT] not sure about the interest of such super soft damping from a print quality point of view, but on my bed slinger, it didn’t hurt, and drastically reduced the noise. Didn’t add any artifacts. But it is much heavier and rigid than the Zero.
