EAF x SAT — Piezo (IT) • Adelaida (ES) • Deathwish @ Société des arts technologiques - 25 Feb feat. Piezo

Finished a first design prototype of a haptic finger pad based on a 15mm by 30mm piezoelectric motor with a ±6V drive input. This design includes 3 3D printed pieces of PLA that fit together to sandwich the piezoelectric motor. The pieces are secured with 2 16mm M2 steel hex bolts and nuts.

Another impro with the pot lid guitar. This time I'm strumming/plucking it, instead of using a bow. I quite like how it sounds. I put a few fx on it, mainly Baby Audio's lo-fi channel strip (some overdrive, low-pass filtering, and chorus).
The Theremin-like sound comes from the Microfreak.

Re: #3dprinting

#bdsensor was a bust because I use an ultra-flat, #MandelaRoseworks heated bed with embedded magnets. Magnets unfortunately fuck with Eddy currents and thus no bueno.
It's unfortunate, I really like the technology and being able to do a scan of the bed by just running the probe across it is awesome and high density scans take essentially the same amount of time as low density ones. Nothing like a 30x30 bed mesh created in under 20 seconds. But alas, I'm back to the #BLTouch. It just works despite not being "best".

I spent a weekend converting the system to #Klipper and while it works, I haven't noted any big benefits compared to Marlin.

In fact, because I need to write macros from scratch and at some point figure out how to use the LCD on the printer, I'd say it's overall more complex. For some reason it's also running slower.

That said, at some point I should be able to wire in an #ADXL345 which will help me deal with harmonics better.

Lastly, I think it would be awesome to use the nozzle as a probe, so I have passively been pondering how to mount #piezo sensors to do so. But my platform wasn't designed for them, so I will probably need to make hardware of some kind.
My thought at the moment is a disc with a lip on it so that it will hold the piezo sensor away from the bed, and then use a aluminum spacer around the bed screws on top/through the piezo so that anything pressing on the bed transmits down to the sensor.

All in time.
