Hello Forum, I would like to use the linear Axis for a different application. So my question is: What is the CAN id of the Axis and the commands to move the slider ? Has anybody done this before ? Any advice/hints would greatly appreciated. (G code commands for the axis, etc) Best regards, Mich…

For your purposes you can completely ignore can and just control the enable direction and step lines like you would any stepper driver. If you need the status of the end stop switch then you would need to monitor for that in can and that gets way more complicated honestly I wouldn’t recommend that p…

thank you very much for your comments. Unfortunately, I need the status of the limit switch. I think I have to work with CAN. I will experiment a bit and see if it is worth it. Does anyone know of any documents/sources that might be helpful in this direction. From another post on the forum I have a …

The best reference is the source code. There’s not much else.

That’s what I thought already. I’m already sifting through the source code and if I have something usable, I’ll post it here in the forum. I can imagine that the very good linear axes from Snapmaker could be interesting for other positioning tasks.

@brent113 . Do you happen to know what the pinout is in the connector for the linear axis ? I can see 8 pins - the two thicker ones are probably the power pins and two are for CAN, any idea what the remaining 4 pins are used for ? Direct stepper movement ?

I’d love to know too. There’s got to be a way to repurpose them for something. Such nice machinery laying idle.

thanks to brent113, I have now an idea how to interface the axis on an arduino based level. I’ll do some experiments and if have have something useful, I’ll post it here on the forum.

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. [image] Snapmaker2-Controller Hardware Connection Official Articles …
