To recap what ive posted in the Other Thread.
Ive Taken the Splitter apart with Top and Bottom Pictures, its a streight through PCB, no Resitors (CAN wise), some small SMD componets (i guess resistors for the Step,Dir and Enable lines) and two Caps for Power smoothing.
The Lasermdule has gotten a basic look at, didnt take it to a PCB Lever Bits yet. It has the main controller PCB for Laserdiode and Fan and a ESP32-S Board for the Camera and its white LED. The black sticker on the Top of the Lasermodule is a Antenna which is connected to the ESP32 board via UFL connector.
The CNC Module again relativly simple in construction. The top of the PCB has all the components on it. The motor inside is a Spinpowertech.com one (which is a quite empty webpage, no infos on their products btw).
My guess, the reason why this motor is on the CAN and not on the “normal Motorcontrolle”, its not a Stepper so a Dir,Step, Enable signal isnt needed, give it Power, PWM, direction and your set.
