Hi, I was referred to the MachineKit group after discussing plans to switch my router machine control from Mach3 on Windoze. He told me that people are using the PRU on the BBB to do the stepper motor control for LinuxCNC. That sounded attractive.
(I have a Gecko motor driver. My system is 4 motors, but only because the x motor is mirrored.) So I did a forum search here and it didn't really clear things up that much. It was pretty down in the weeds. What I'm trying to figure out is whether using MachineKit LinuxCNC and the BBB with the PRU is standard fare or not. I have basically two choices as far as I can tell: 1. Use MachineKit and a BBB I have lying around, and the PRU as stepper control. Ride off into the sunset. 2. Use a Mesa 7i92 for stepper motor control and standard LinuxCNC instead of MachineKit, making sure that I have a realtime kernel installed one way or the other. I'd probably still use the BBB as my CPU. Although I like the idea #1 above because it is a one board solution (and I save $89), the most important thing is that I choose the system that is easiest to set up and most reliable. Does anyone have any opinions of which that might be? If both of these configurations are regularly used, then I'll go with BBB and PRU and MachineKit, since I can try it all out for the cost of my own time. But I value my time so I don't want to get too experimental. Thanks for any help!! -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
