Bambu lab release new the A1 mini, using hotend pressure.
I think this is light enough on the MCU

bambulab a1 mini measure Inductance for pressure advanced auto calibration
Prusa mk4‘s hardware can do same thing.
I’m interested in how they do auto Pressure Advanced
without computer vision

@nikscha Here is a post about sampling speed

@T3P3Tony Reimplementing not porting.

Does closed source firmware reimplementing the CAN message protocol violate the GPL?

@gloomyandy For example, the Protocol 2.0 used by DYNAMIXEL XL330-M288-T, PWM servos cannot be used for torque control and speed control. Two-way communication can be used not only for servos maybe digital sensors or other non-real-time device control.

@droftarts Hope it can be used on Expansion boards. The serial bus servo can be connected to IO 0 of 1LC.

Improve servo motor scalability, position, speed, and torque support
Perhaps it can be controlled by commands similar to M260

Bambu Lab may also use a similar algorithm to achieve flow calibration.

@penguinya Just early version, I think it is ok.

@Charlie According to the simulation results, the impact on printing is unobservable.
