Use of linear Axis independently of Snapmaker -Controller

[rst]

Hi, I had the same idea about building a custom device using the SM aixs modules, which really look great. From what I have read in the forum so far, the cable seems to have both CAN and the stepper pulses.

Snapmaker2-Controller Hardware Connection

This is the hardware connection of the Snapmaker2-Controller, it indicates how different modules communicate with each other via CAN-bus. [Hardware-Link] Controller <-> Luban USB to UART: Communication between Controller and Luban is original Marlin supported Gcode. Controller <-> HMI UART: Communication with HMI using SSTP (Snapmaker simple transformation protocol) USB 2.0: Provides the link to read/write USB stick plugged in Controller <-> 3D printing module Wired link: stepper sign…

Move old linear modules with Arduino?

I upgraded my linear modules, and now find myself with a need for linear modules for a non-sm model railroad project. I’m wondering if there is a way to control the old modules with an Arduino or such sending PWM to them? I’m kinda ready to just start testing but don’t want to fry anything unnecessarily! Thanks for any thoughts/help - FAS

Hence, wouldn’t it be possible to connect the axis modules to a different controller, e.g. a GRBL shield without drivers? I have to look further into it, my guess would be that what goes into the stepper driver on the GRBL shield could just be sent to the SM axis modules.(*)
I imagine that this would be an easy and straight-forward solution to control a custom setup with G-code, without having to worry about too many things.

Any thoughts?

(*) EDIT: Just looked it up, the axis modules could be connected to an arduino running GRBL, no need for the hat carrying the drivers. However, any other more advanced printing/CNC controller with MCU on board could also be used this way, i.e. by leaving out the driver modules and just connecting the Snapmaker axes - so more axes and additional functionality would be available.
