I want my desktop to look like this：https://www.tecmint.com/wp-content/uploads/2013/07/xfce-11.jpg
 

I like the mouse background! Is that still available as an option in LinuxCNC?

It reminds me of the startup screen on Heidenhain TNC640, since it's no secret that it's just an application running in Linux on XFCE desktop. In fact, my job programming for and running a Hermle 5-axis mill is part of why I decided to finally start using LinuxCNC at home.

I am otherwise totally new to Linux, and I haven't even bothered to figure out how to change the desktop background yet. I am one of those weird people that usually keep the default desktop background.

Excellent news!

Yes, duty cycle is the correct pin.

Is the frequency reasonable and the valid bit set?

It sounds like the EDM output is single ended which means:

1. The EDM duty cycle output should connect to TB2 pin 13 (IDX+)
2. The EDM signal ground should connect to TB2 pin 15 (7I96S ground)
3. The 7I96S IDX input should be jumpered for TTL mode (W1 left)
4. 7I96S IDX- (TB2 pin 14) must be left unconnected

Note the if you connected the inputs to TB2 pins 13 and 14 without a ground
and ran the EDM system you may have damaged the EDM output or
7I96S input.
 

I should have explained more.
point = [wx, wy, wz]
if not self.plotdata or point != self.plotdata[-1]:
self.plotdata.append(point)
This adds a plot point. We would need to change it to also add color.

point = [wx, wy, wz,color]
or maybe better:
self.plotdata.append([point, color])

then later in the file:
#GL.glColor3f(1.0, 0.5, 0.5)

GL.glBegin(GL.GL_LINE_STRIP)
for p,c in self.plotdata:
GL.glColor3f(*c)
GL.glVertex3f(*p)
GL.glEnd()

a few other initialization and clearing details to follow up. but that might work.

Another update.  It seemed that I didn't have the Mesa tied to ground properly.  It is now tied to earth ground (I also tied the shielding into earth ground). The jittering all went away and now the 'hm2_7i96s.0.periodm.00.duty_cycle' is sitting at 0 even when the EDM is running.  Anyone have any ideas? 

Is 'hm2_7i96s.0.periodm.00.duty_cycle' the correct pin?

I have tried various ways to use this code, but so far no results..
