From what I recall, from a along time ago when we were fixing threading , what I say is true as it applies to the internal threading
code. 

I would have to look through a lot of notes to see if my exactly wording is correct....I think so as the words are not mine.

Index debounce is relative to the number of times a stable  index pulse is seen by Mach before it will accept the index signal.
The amount of debounce required varies from system to system. A value of one is not practical since it's not possible to average the
the true rpm. If you set it really high you could be waiting  be waiting a long time before implementation of threading.

Stephane,

You will find it in Config>Backlash.That is where you define the backlash, speed , and if you want to  enabled  it.

 I DO NOT KNOW HOW TO DO IT

What are you talking about?

Using the xml reader or about xps file?

If it's the about xps files I have never used them. Below is info about XPS.

XPS Functionality Included With Windows

Windows Vista, Windows 7, and Windows 8 all include built-in XPS tools. Even Windows 8 has better support for XPS files than it does for PDFs.
•Microsoft XPS Document Writer: Microsoft installs a virtual printer named “Microsoft XPS Document Writer.” This printer creates XPS files from documents you print to it. It’s like a “print to PDF” feature, but less useful because it’s not as compatible with other software.
•XPS Viewer: The included XPS Viewer application allows you to view XPS documents on your desktop.

LC is what it is and anything I know about it is in the manual I wrote.
It's not like some other CAM software. See page 18 of 23 in the manual  for my definition of what Set layer Depth does.
Thus  there is no "set material thickness". I guess if you wanted to have something appear in the graphics one could have a layer
which would represent the material foot print and set that to a some depth below Z=0.

BTW, it must be accurate as you are the one telling LC how deep to cut a layer.

Machscreen Screen Designer / Re: Assign Led to step value
« on: September 10, 2017, 10:22:55 PM »
Hmm.....
I didn't find a LED which is associated with any of the Jog Increment positions for 1 to 10.
May be able to add some scripting which would turn the led on/off.
Can't be of much help on the scripting.

Make it easy by adding the Jog Mode button so you can toggle between Cont, Step, MPG.

Otherwise, have a check of the button / led / dro list if  there is a button to just select step.

"Whats your opinion on closed loop steppers?" :)

Teacher responds:

That is a very good question Grasshopper, but, since you didn't do the homework ( reply #36) like all the other students did, go sit in the corner of the cave with your candle and envision $400 + for one ball screw, the whipping of the existing screw at 30 ipm, not being able to hold tolerances because the existing wimpy screw may have  antibacklash nuts that need constant adjustment.

Now go sit in the corner and think about it all....and remember Grasshopper:

You can have anything off the shelf your heart desires but once you choose it
you must pay for it. Some times that which one envisioins may not be a complete truth.  ::)

FWIW,
Radio Shack did sell a small 1/8" diameter  x 1/16" high rare earth  magnet. Very easy to just crazy glue to about anywhere
making sensor installation very easy.
