I've converted my mini-mill to 3-axis CNC using the BBB and Machinekit on
the 2-12 image. It works great and I love this conversion! When I grab a
more recent image (3-26) I run into a variety of problems, some of which
get fixed by building machinekit from sources on the BBB, but the app still
fails to load.
I've modifed the CRAMPS config since my settup uses steppers with Toshiba
6600 based drivers. The PRU's are used in that config to run
step/direction. I've modified 'setup.sh' to use the updated path for
bone_capemgr and to load 'cape-universal' and BB-ADC. The script calls for
'helper' and 'uio0' but I can't find these or know if they are needed.
Commenting those out yields:
machinekit@beaglebone:~$ machinekit

Is there an updated config that works with the newer images, or a howto on
how to proceed?
Thanks for your time and help!
