@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.

Just an updating.

@Charlie Yes prusa has implemented it

@penguinya The introduction of bambulab confirmed my guess.

@nikscha Here is a post about sampling speed

find a better chip for load cell.
CS1237 http://www.asidesigner.com/Files/PartFiles/15315/222/cs1237_datasheet.pdf
spi bus 1.28kHz ADC and PGA

@nikscha Bambu Lab tests pa every print, and 50ms really slow, HX711 can reach 80HZ, Prusa using HX717 320HZ, higher the sampling frequency, the more beneficial for auto PA testing.

Automated PA testing is still an early idea. I hope to implement z probe and collect enough PA pressure data for research.
