I'm using the Melfa robot as a template for my robot.  I have my DH params loaded and I even had my cad running in vismach.  I added new Cad files and something broke. 

So my moveogui.py looks like so...
Code:
try: # Expect files in working directory     # create toolholder from file     link7 = AsciiSTL(filename="link7.stl")     # create wrist from file     link6 = AsciiSTL(filename="Joint4.stl")     # create forearm from file     link5 = AsciiSTL(filename="Joint3.stl")     # create ellbow trom file     link4 = AsciiSTL(filename="joint2.stl")     # create upper arm from file     link3 = AsciiSTL(filename="joint1.stl")     # create shoulder from file     link2 = AsciiSTL(filename="joint0.stl")     # create base (waist) from file     link1 = AsciiSTL(filename="base.stl") except Exception as detail:     print(detail)     raise SystemExit("moveogui requires files link[1-7].stl in working directory")

And I get the folllowing error can find "joint2.stl"  and
Code:
Running HAL command: loadusr -W moveogui Running HAL command: net :kinstype-select <= motion.analog-out-03 => motion.switchkins-type Starting DISPLAY program: axis [Errno 2] No such file or directory: 'joint2.stl' task: main loop took 0.109735 seconds Shutting down and cleaning up LinuxCNC...

I know the file is in the source directory and is in ascii format.  What am I missing?

Linux is case sensitive, I notice you use file names with uppercase 'J' and others with lowercase 'j'. Maybe the file name is actually 'Joint2.stl'?

That was it, the case.  I don't know how I missed that detail.

And I found one Cad file in Binary.  Question, is there a practical size limit to the Cad files you should loaded as links?

Not that I'm aware of but depending on your hardware I would expect things to start to get sluggish at some point.
