Hydraulic press brake control

I am using Debian with 2.7 and a component for the ssr's that PWC helped me make. There is no support in the pnc config just yet. You could use a different board in the pnc config and then just change the board info in the hal. I have a working 3 axis plasma cutter running on the 7i96 and can give you those file's including the comp if you like. otherwise you need to use the version 2.8 from the master to get the ssr's running. I'm probably going to switch to that myself and ditch the comp.

I've made progress this week. I made a comp to get things moving. It does work but I have no homing sequence yet and the movement is a little jumpy. Also need to change the steppers to closed loop. Just doing position for now. Attached is my files and a link to a video of the machine moving.

found that my compensation was not linear so I changed it up. Things are much soother now. I need to make the steppers on the valves closed loop as I've found that if you hit the pressure relief and it causes a pressure spike witch kicks back on the valve causing it to loose position. attached are my updated files.
