Re: LinuxCNC with Mesa 7i76e Control Issue
Matt, you are in very good hands with PCW but really the first question is do you have holding torque when you fire up your machine? eg. you should not be able to turn your motors by hand. If you can, you have a wiring problem to sort out.
The other tip I have is that its easy to get the number of steps per mm/inch wrong. When I fired up my 7i76e for the first time, I had holding torque but I did not see movement. Then I saw the tiniest of movement and realised it was working! I just needed to correct the steps per mm and I was away.
Also be aware that you must home your machine before you can jog. (estop off, machine on, home all). You might need to read the homing configuration section of the html docs.
V2.7 is very old now and the dev team is frantically trying upgrade the release version to 2.8. V 2.9 or master branch is the development branch that new features are added to. Sometimes it breaks. But having said that, I've only ever used master branch. I think 2.8 is a better bet today as there is some issues in V 2.9 with converting from Python 2.7 to 3.0 that you don't need to get mixed up with...
