Simple G7x Profile editor for Linuxcnc/Axis

Hi guys, 

Created this simple, but effective profile editor for myself. 
It is a lightweight Tk-based conversational editor for lathe profiles, designed for LinuxCNC / PathPilot style workflows.It lets you sketch, edit, and preview turning profiles interactively, then generates a G71 or G72 roughing cycle with a G70 finish pass. All core functionality uses only the Python standard library (Tk), so it can be dropped directly into a AXIS environment.Optional DXF / 3MF import is supported via external libraries.

For example you can: 
 

1. import an STL as a background reference
2. Auto create segment points or (recommended) tracing the rotational outline with profile points 
3. Adding chamfers and radii for finishing details
4. Adjusting geometry for optimal cutting
5. Setting machining parameters
6. Generating G-code
7. Sending to LinuxCNC/AXIS

Hi, great tool — thanks for sharing it!

I ran into two issues with the generated G-code on a standard LinuxCNC setup (not PathPilot), both easy to fix:

**1. D and I parameters are swapped in the G71/G72 line**

The generator outputs:
```
G71 Q#### D{stock_allow} I{doc} R... F...
```
But LinuxCNC G71 expects `D` = depth of cut per pass and `I` = finish stock allowance — the opposite of what is currently generated. With the values swapped, the cycle runs with a 0.2 mm DOC and a 2 mm finish allowance instead of the other way around.

**2. X and Z arguments on the G71/G72 line cause the machine to stall**

The generator adds `X{start_x} Z{start_z}` directly on the G71 line:
```
G71 Q#### X30.000 Z2.000 D... I... R... F...
```
LinuxCNC does not accept X/Z on the canned cycle line itself — the approach is already handled by the preceding `G0`. With these arguments present the spindle starts but the machine does not move.

**Fix** — patch profiler.py (4 occurrences):
```bash
sed -i 's/X{start_x:.3f} Z{start_z:.3f} D{p.stock_allow:.3f} I{p.doc:.3f}/D{p.doc:.3f} I{p.stock_allow:.3f}/g' profiler.py
```

After the fix the output looks like:
```
G0 X30.000 Z2.000
G71 Q#### D0.500 I0.200 R1.000 F100.0
G70 Q#### F50.0
```
Which runs correctly on LinuxCNC 2.10 with AXIS.

Hope this helps, and thanks again for the project!

Thanks for reporting this. I am a little pressed for time these days, so I don't know when I get around to checking and fixing it. 

 

Good morning everyone. But does this conversational lathe software only work with Axis or does it have its own native GUI?

It has its own GUI....I have not tried it with other UI's, but should be able to work. You can save the g-code and load it in any Linuxcnc ui.

In the readme->quick install section it mentions the 'standalone' mode

HI good mornig at all.
The GUI, can running on Debian 10 ?

Thanks
