Gene, just expanded to dual par ports, and am eliminating optos from my stepper drives with a direct via db25 Bob . My drive is +-10 and I do have a Chinese opto'd bob that has a pwm , but it is not bi-directional . And I don't really want to put a flip flop relay in the output , so I'm still rather trying to solve this puzzle. I just tried the mesa site for that spinx 1 card and it appears the site is down, or my internet here in East bfe Ozarks could be causing issues as we are one of only 5 houses on this road out here. I will likely go to an fpga board when I get ready to do servos. I am also going to get some of those omron encoders as I would like to Ridgid tap with this machine eventually . I am nearing completion of a bunch of retrofit upgrades since I cabbaged this old knee mill to CNC 5 years ago . It's been a bit of a road after some surgeries, a new wife and baby the last year or two but I'm finally seeing this thing near fully functional and I want to put a fourth axis and lathe spindle on this machine as well. I'm trying to get it all together with what I have on hand to get it all under cnc control.
I have been paying attention to your ramblings on the old Sheldon and the pi retrofit and find it quite interesting. And have considered making a go of the pi on my next machine. But I'm trying to get this one to make a few $ I also found a couple threads on the forum about rs485 but I haven't concluded if that was pwm or serial data and the night is almost long so I will dig deeper after the sun comes up. ------------------------------------------------------------------------------ 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
