I can't seem to get TNG v2 to display in workpiece diameter (G07) mode, it always shows as a radius value for me.

G07/G08 defines how input coordinates are interpreted. It does not affect display. Just like all other modal state Gcodes.

[blowlamp]

Oh OK. In that case I'd like to suggest having an option to show a diameter reading for lathe users, please.

[PlanetCNC]

You can define your own expression in state file. For example:

expr "2*_hw_work_x" 3 "Diameter"

[blowlamp]

I'm trying, but I can't even gain access to change the Profiles folder.
Even though only I use this computer, Windows 10 says I need Admin permission. :devious:

Martin.

[PlanetCNC]

Then do this as admin. Or install TNG somewhere else.

[maki]

I am using TC for that, simply copy existing file to other (workable) folder, make changes, copy it back (TC will ask for replacing =yes) it wil also ask if using admin privileges = yes, that is....
you must adjust TC to show "all" system files !

[blowlamp]

Thanks for your help. I've got it working now. :cheers:

I uninstalled/reinstalled TNG in a different folder, but the Profile folder disappeared & I couldn't find it anywhere until TNG was put back in its default location.

In the end, I created a State1.txt file on the Desktop and simply Copy & Pasted it into the Profile folder. I could find no way to gain permission to save straight to the Profile folder.

Maki, what is TC?

Thanks again. Martin.

[maki]

TC - Total Commander, free tool

[theRat]

I could find no way to gain permission to save straight to the Profile folder.

The best thing to do is to add modify permissions for All Users to the profiles folder. That way you can then just edit files at will. It would be nice if the TNG installer would do this (either for All Users or just the user that is doing the install).

You can define your own expression in state file. For example:

expr "2*_hw_work_x" 3 "Diameter"

I'm trying to solve the same problem and I can't find the file I need.

[adidoro]

I'm trying to solve the same problem and I can't find the file I need.

I think THIS was the solution.

[R2D3]

I created a State.txt file in the profiles folder with the text expr "2*_hw_work_x" 3 "Diameter". Looks like it didn't work. I just don't understand what I'm doing and why....:tired:

I need to: 1) Choose which axis I need to switch G07/G08 (X,Y....)
2) The working coordinates of the selected axis were multiplied by two(Work coordinate is equal to the workpiece diameter when switching)

[leomonti]

Has anyone found a working solution? I too would like, on TNG, to display the diameter on my lathe dro

[toni123]

It would be a helpful feature to get the X-Value of the Workpiece-Coordinate -System doubled. I have tried the the solution that mentioned above, but wasn't sucessfull.

I have created a "expr_diameter.txt" file in the profile folder with the following text:

expr "2*_hw_work_x" 3 "Diameter"

Nothing happened. Then I have added a the text "onInit", but this also didn't work. I have read that the parameter "_hw_work_x" is a read-only Parameter. So how can it be possible to overwrite the shown value on the display of the workpiece coodinate system.
Or was the above mentioned solution only for displaying the double X-Value to the output window?

Can anyone please provide us us with a "ready to use" programming / code to show the x-Value double in the workpiece coordinate system?

In lathe-mode, it is very confusing to see on WCS the radius values instead of diameter values.

Thanks for a possible solution!
Toni

[leomonti]

@toni123: I completely agree. I really miss this feature too.
Any lathe Dro offers diameter/radius switching.

[PlanetCNC]

Here is state file example for lathe. Just copy this file to your profile folder

[toni123]

Thank you for the quick response!

I have copied the file "State_Lathe.txt" in my Profile folder and restarted TNG. Machine Typ is Lathe.

Sadly, nothing changed. When I run a g-code programm (with G7 definition) the values in WCS show unchanged radius values as before and not diameter values. Seems like the script isn't working.

[PlanetCNC]

Yes, it is working. See "State" panel, tab "Lathe".

[toni123]

Ok, I thought it would be possible to change the original X-Value of the WCS (the red one in the picture)

Switching between State tab and IO Tab isn't much comfortable.
