I personally find BBB pretty interesting, PRU amazing and so on. But what BBB really lacks is computing power. It's just terribly slow, unfortunately. RPi 3 is probably 3 times faster and it's still not fast enough. Also it's pretty disappointing that Machinekit is not going to merge joint_axes... While I own 2 BBBs (and CRAMPS which I have not even used yet), I almost gave up on this stuff. OTOH I still hope for RPi & 7i90 to control at least some DIY robots. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
