BeagleBone with G540?

Has anyone used the G540 with the BeagleBone yet? I either will be running a NUC with some horribly bastardized USB-DB25 solution but I know there are ways to replicate the parallel controls on the BBB but I seem to be finding only a severe lack of information and documentation on it. Any suggestions? This will first just be for a 2d laser (on rails originally designated for light cnc milling and cnc plasma)

I currently have a BBB running machine kit with a custom cape, which would work with a G540. USB not an option for LinuxCNC or machine kit.
I used the PRU drivers that come with MK for step generation.
When I get home from work I can give you more info. github.com/ozzyrob

That won't work. LinuxCNC has no way to work with USB.

You could use a BBB and custom DB25 cable, and then the steps can be produced by the PRU. The G540 interface is just a bunch of wires.

Alternatively, your NUC + Ethernet + 7i92 can plug straight in to a G540.

Don’t forget the BBB doesn’t like 5v on it’s GPIOs hence the set of boards I made, they do the level translation.

What cable is this? I thought it wasn't compatible voltage wise.

You'd have to make your own cable for the BBB.

The G540 should be ok driven by the the BBB GPIO's without any level translation (you'd have to check the spec sheet) but any inputs to the BBB from the G540 would require level translation, otherwise the BBB will go to Puppy Heaven.

If you like my idea I have some spare boards available.

But honestly if you have a NUC grab a 7i92 from Mesa....I'm currently moving away from the BBB to a Mini ITX board and 7i92 setup.
The Linuxcnc support is a lot better than the Machinekit Support ( which is the better option for the BBB imho).
