+## Project
+LinuxCNC configuration and custom G-code macro library for a Lagun milling machine.
+
+## Structure
+- `configs/lagun_gmoccapy/` — machine config (INI, HAL, tool table, pendant)
+- `nc_files/subs/` — macro subroutines (auto-loaded via SUBROUTINE_PATH)
+- `nc_files/programs/` — standalone part programs
+- `nc_files/HEMA/`, `HEMS/`, `HEQJ/` — project-specific part programs
+- `nc_files/*.ngc` — older part programs (root level)
+- `datasheets/` — Mesa board PDFs
+
+## Key docs
+- `nc_files/MACROS.md` — macro API reference
+- `nc_files/OFFSETS.md` — work offsets, tool offsets, cutter comp quick reference
+- `nc_files/TOOLS.md` — deep dive on tool changes and GMOCCAPY interface
+- `configs/lagun_gmoccapy/README.md` — machine config, wiring, HAL, pendant mapping
+
+## Macro conventions
+- All macros in `nc_files/subs/` use lowercase filenames (LinuxCNC matches `o<name>` to `name.ngc`)
+- Mode bitmask is always the FIRST positional arg (#1) for macros that accept it
+- Z heights come from globals `#<_z_top>` and `#<_z_bot>`, not positional args
+- Tool diameter comes from `#5410` (built-in LinuxCNC param, requires T M6 G43 first)
+- Optional globals: `#<_z_clearance>`, `#<_rampang>`, `#<_stepover>`
+- M101/M102 enable/disable Z-axis CNC control (for manual quill operation)
+
+## When editing macros
+- Do not change functional behavior without asking — these run on a real mill
+- The `o<number>` labels (o1, o101, etc.) must be unique within each file
+- LinuxCNC G-code uses `[expressions]` for math, `#<name>` for named params, `#N` for positional args
+- `G90.1` = absolute arc centers (I/J), `G91.1` = incremental arc centers — check which mode each macro uses
+- Test calls should never appear after `endsub` (they execute on every load)
+
+## When editing caller programs
+- Programs set `#<_z_top>` and `#<_z_bot>` before macro calls
+- Mode arg is first: `o<pocket_circ> call [0] [x][y] [d] [fincut]`
+- Commented-out calls (`;o<...>`) should keep their format consistent with active calls
+
+## Machine details
+- 3-axis mill: X (+-24"), Y (+-12"), Z (-4" to +1")
+- Mesa 5i24 FPGA + 7i52 servo interface + 7i37-TA isolated I/O
+- Dual PID on X and Y (motor encoder + linear scale, outputs summed)
+- Z has special override mechanism (M101/M102 via logic AND gate)
+- GMOCCAPY GUI, XHC WHB04B-6 wireless pendant
+- Units: inches
+- Manual tool change (no ATC)
