Turn G-code: conversational lathe cycle generator for LinuxCNC (12 cycles)

Hi all,

I run a small CNC lathe on LinuxCNC, and I got tired of writing the same turning, threading and grooving code by hand. So over the past months I built a desktop tool for it: you fill in a form (diameters, lengths, feeds, speeds), watch the toolpath in a 2D preview, and save a ready .ngc file for the machine.

What it does - 12 cycles:
- OD turning, facing, boring, grooving, drilling, cut-off
- Taper (OD/ID), sphere (including concave profiles, e.g. a pulley groove)
- Chamfer / radius (OD/ID, front/back)
- Threading: OD/ID, right/left hand, multi-start, adjustable lead-in / run-out
- Tapered threads
- Archimedean spiral (face spiral groove)

Things that were important to me:
- Live 2D toolpath preview before you save anything
- G7/G8 (diameter/radius mode) with one switch for all cycles
- G32 or G33 threading syntax, with a configurable pitch word (I/K/F)
- Coolant M-codes, tool number, comments, M30 - all can be turned on or off to match your habits and your postprocessor
- mm and inch; English and Russian UI

Most cycles (turning, facing, taper, sphere, threading, boring, chamfer/radius) have been proven by real cuts on my machine, not just air runs. Tapered threads and a couple of others so far only have air / single-block runs - feedback is welcome.

To be upfront: this is paid software. There is a free 15-day trial, no key needed. After that it's $25 for one month (no auto-renewal), or $60 for 3 months and then $20/month. Linux .deb (Debian 11+ / Ubuntu 20.04+, amd64) and Windows.

I know there are free options too (NGCGUI, Probe Basic conversational, etc.), and they are great. This one is aimed at people who want a complete set of lathe cycles in one simple form, with a preview, without writing subroutines.

Happy to answer questions, and I'd appreciate honest criticism.
