Qtdragon for lathe??

Has anyone gotten this working cleanly?

Built qtdragon with pnfconf and set mode as lathe.

Still seeing Y axis on the screen

Need to change the default view to look at xz only

Keyboard shortcuts work when nothing is homed. as in Left and right move z (towards spindle)  up and down move x (The cross slide). However once homed the keyboard shortcuts go to typical mill fashion where x is left and right...... and z is page up and down. 

I wasn't seeing a lathe specific config, hoping I missed something???

I don't mind being the test monkey if anyone could fix those....I'm also going to get my hands dirty learning at to make some changes for tube cutting in qtplasmac and could hop over to building a lathe when done with that.

Seems like the lib/python/qtvcp/designer/readme.txt has the basics for getting started. Anything else I need to know?


Thanks!

AFAIK no one has used QtDragon on a lathe. It was not built with that in mind I would say.

Saying that we could modify it to make it more suited.
What version of linuxcnc are you using?

Well mark me down as the first!

Cut a few parts yesterday worked better than I was expecting (was originally debating going to back to gmoccapy but mill is on Qtdragon so similar interface would be nice) glad I have it a shot.

I have both 2.9.2 and 2.10 setup in for run in place so whatever you would prefer working with I'll do. Just let me know when to pull.


Few more ideas after using the machine.

Gmoccapy has displays for both radius or diameter and changes which is highlighted depending on your g code called g7 (dia) or g8 (radius). This is displayed instead of an "x". Nice but not necessary feature.

Some lathes do have Y axis for milling and spindle that can position itself for milling operations (C axis). I don't need this but someone will.

Where the mill tool is on the main page. Would be nice to have a lathe tool but this isn't as useful as it is on the milling side the tool diameter offset isn't useful to know. (Unless it could be edited to dial things in e.g. diameter .01 oversized adjust offset .005 to compensate).

The sfm calculator (surface units per min) would be easy to calculate for lathe tools by just multiplying the spindle rpm by 2π "x position with current tool offset" to get the sfm.

Trying to brain dump before I forget.
Thanks!

I would be very interested in a lathe-focused version of Qtdragon.

Some wishlist items:

• Parts counter
• Multiple spindle display/control based on INI num_spindles (sub & live tools)
• Placeholder(s) for spindle load and axis load indicators
• DRO display based on INI (show C- and Y-axis)
• SFM display (as mentioned earlier)
• Chipload display (ipr/mmpr)
• Easily 'flippable' backplot views
  • Some lathes are 'normal', some are back-tool, and some have both tool orientations.  An automatic (or semi-automatic) method of flipping the display based on tool orientation (and maybe spindle direction) would be extremely helpful for visualization.  @Aciera and I discussed this last year a bit.
  • In addition, being able to flip the Z-axis for subspindle work would be nice
• Collet/chuck status and/or controls
• Parameter value display tab/window
  • I use parameters frequently for things like part length, parting tool width, and similar job-specific values for use in barfeeder/puller and part-family calculations .  Being able to quickly view/verify what's in the .vars file would be spectacular.

Just figured I'd throw this out there...

Did some preliminary hacking om qtdragon:

Wow that was fast! Looks great! 
Let me know where it is at on git and I'll test the operation/workflow. 

 

Pushed a development screen/sim config to master branch (2.10 pre)
Look for qtdragon_lathe
Early days of course..

Hello,
I have just started working with LCNC and I am therefore an absolute beginner. 
I have found the files for qtdragon lathe on github (share/qtvcp/screens/qtdragon_lathe).
Unfortunately, it is completely unclear to me where I have to copy these files and which adjustments are necessary so that I can start qtdragon_lathe. Maybe someone can name the necessary steps.
Best regards

If you are using linuxcnc 2.9, I'm not sure they will work.
In linuxcnc 2.10 (master version), they are included.

What version are you using?

I have installed the latest LCNC 2.9 ISO.
