That sounds like a good target to aim at.
If you want to do it that way, I'll need something I can plug my stepper drivers into. They're not like "big iron" with wires and such, they're just little circuit boards (about the size of an SD card) that plug onto the interface board. Here's an eBay posting with some good pictures...the stepper drivers are the 5 small boards in the lower-left of the main image, next to a USB jack on the Arduino which gives a sense of scale: http://www.ebay.com/itm/Iduino-Mega-2560-A4988-RAMPS-1-4-LCD-SD-Ramps-Cooler-fan-ect-3D-Printer-reprap-/190845097970?pt=LH_DefaultDomain_0&hash=item2c6f4117f2 >> I can create a BBB signal chart to make a HAL from for the K9.

It's a bit hard to say without seeing your board, but to me it seems focused more on traditional LinuxCNC applications, with 25-pin parallel port connections. Is this correct? If so, I can quickly whip up a HAL configuration file for my PRU code and make a device tree overlay to setup the pin multiplexing if you can get me map between the BeagleBone header pins and the desired function. ...but it will be hard to hook a 25-pin port to my 3D printer. - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlG2ODsACgkQLywbqEHdNFxYcwCgp+T3IJsDhHaC1l3ekCS0/rwf KhkAni9PB82I1Sug62NN8KXPyR1SvhSS =p49W -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
