Qtdragon for lathe??

The lathe screen is only available in the development version (2.10 master) of linuxcnc.

You're an ace dude !!!

I'm sure it will need more tweaks - lets me know.

Hi Chris,
I noticed that my screen included a scroll button in the DRO section which I didn't want/need and this appears as if it maybe part of this change?

I was looking for "MACHINE_TYPE_HINT" in the documentation and via GIT, found a few references but none that indicated
acceptable values.
 

All qtdragon versions have that button now. I'd you have an MPG you might like it to scroll the gcode, mdi or graphics view. There is no option to remove it currently.

Got it. No problems.

Ahhh, I misunderstood.

"scroll the gcode, mdi or graphics view" now understood.

Thanks

Hi Chris,

Thanks for the Lathe GUI. I've tried to set it up using 2.10 but ran into a few issues.  I did my setup for my lathe in pncconfig selecting QTDragon as a gui.  After I've completed the setup I changed the DISPLAY setting in the .ini file to qtvcp -d qtdragon_lathe.  Is this the correct way or is there another way to setup qtdragon_lathe?  I'll elaborate on the issues if my attempt was correct. 

I've modified a manual mini lathe to cnc to test some lathe features and would gladly assist with practical issues with the development of qt_lathe.

Yes, that is a good start.

It is under developed, but I will help as I can.

There are a few extra pins:
qtdragon.axis-x-load (float input range 0-1)
qtdragon.axis-z-load (float input range 0-1)
qtdragon.spindle-load (s32 in put range 0-100)

wear offsets are available when using remap - the wear will be shown in the tool offsets page regardless.
qtdragon.mpg-in (s32 input for scrolling things on screen)

Thanks.  The first issue is the output to control the spindle speed. I use a mesa 7i76e card with 0-10V as reference voltage on the spindle port TB4. The output won't go higher than +5V or for that matter, 50% of any reference voltage that I use.  The spindle also starts turning at 50% of the maximum spindle speed output setting when I use the slider in manual mode to control the spindle speed.  (The spindle only starts to run when the slider is in the middle.) The reason why I suspect that the issue is related to the qt_lathe gui is because when I do the exact same setup with pncconfig selecting AXIS as gui, the maximum output is the the same as the max+ reference voltage. 

The output is similar to "bipolar mode" as descibed in the 7i76e manual p15:as in the screenshot of the manual..     

I also noticed that the -5V to +5V (or 0-10V) output setting in the Spindle section of pncconfig for qtdragon has no influence on the output voltage of the spindle speed control. Whether the box is selected or not it makes no difference. 

My current goal is to get the lathe running with the correct axes and spindle control.  Once that is sorted I'll inform you of the other issues as I find them.

Remark:
The issue was resolved by changing the OUTPUT_SCALE parameter in the .ini file to a value of 1000.  As I read through the comments in the forum regarding the OUTPUT_SCALE value I realised that this is not an absolute value. 
 

Can you post your config files?
