Worked for 54 sec
Il placement ora è senza collisioni rilevate, ma il report di densità continua a segnalare congestione seria. Eseguo il pre-check dell’autorouter; se conferma il blocco, passo a 4 layer per tentare il routing senza cambiare la meccanica.
Worked for 57 sec
Il pre-check autorouter non ha trovato blocchi, solo avvisi su GND pour vuoti/da rigenerare. Avvio ora il routing completo mantenendo fissi i controlli meccanici.
Thought for 3 mins 10 sec
Ho completato il placement elettronico: tasti, encoder e USB-C sono protetti/bloccati; MCU e passivi sono stati spostati per togliere collisioni, mantenendo fissa la meccanica. Il pre-check routing è passato senza blocchi gravi, ma il routing automatico non è partito perché l’account non ha ACUs disponibili.
Open item:
- Routing non eseguito: serve disponibilità di ACUs per continuare.
- Restano avvisi non bloccanti sui GND pour vuoti, da rigenerare/verificare dopo il routing.
Prossimi passi:
- Aggiungere ACUs.
- Riprendere il job di autorouting.
- Verificare airwires/DRC dopo il routing e fare cleanup mirato.

Case-v3_002302.stepLid_002330.step
Coordinate convention used
- STEP XY coordinates were converted to PCB layout coordinates by using the USB/grid-centered datum:
- STEP datum X0 = 43.970 mm
- STEP datum Y0 = 41.751 mm
- PCB coordinate = STEP coordinate - datum
- This keeps the USB-C opening centered at PCB X = 0 and aligns the extracted MX grid to a 19.05 mm pitch.
Board outline applied
- Applied PCB outline: rounded rectangle, 89.0 mm × 83.6 mm, 3.0 mm corner radius.
- This is a fit outline derived from the case/lid extents and slightly expanded from the first extracted pocket so the actual hotswap and encoder footprints are not clamped by the board boundary.
- Routing remains deferred.
Mechanical anchor extraction
MX switch grid
The STEP geometry contains a regular MX-style 19.05 mm grid with nominal cutout centers:
Table
| Column | STEP X (mm) | PCB X (mm) |
|---|---|---|
| C1 | 15.523 | -28.447 |
| C2 | 34.573 | -9.397 |
| C3 | 53.623 | 9.653 |
| C4 | 72.673 | 28.703 |
Table
| Row | STEP Y (mm) | PCB Y (mm) |
|---|---|---|
| Top | 53.604 | 11.853 |
| Middle | 34.554 | -7.197 |
| Bottom | 15.504 | -26.247 |
Applied 11-key assignment
Updated per the user's reference photo: 3 switches on the top row, encoder at upper-right, then 4 switches on the middle row and 4 switches on the bottom row.
Table
| Component | PCB X (mm) | PCB Y (mm) |
|---|---|---|
| SW1 | -28.447 | 11.853 |
| SW2 | -9.397 | 11.853 |
| SW3 | 9.653 | 11.853 |
| SW4 | -28.447 | -7.197 |
| SW5 | -9.397 | -7.197 |
| SW6 | 9.653 | -7.197 |
| SW7 | 28.703 | -7.197 |
| SW8 | -28.447 | -26.247 |
| SW9 | -9.397 | -26.247 |
| SW10 | 9.653 | -26.247 |
| SW11 | 28.703 | -26.247 |
The top-right MX cutout is left unpopulated because the encoder occupies the upper-right position in the reference layout.
Encoder
- User-provided reference photo (2026-07-21) shows the encoder at the upper-right of the key cluster.
- Right circular lid/case opening center extracted at approximately STEP (76.824, 68.351) mm.
- Applied encoder position: ENC1 = (32.854, 26.600) mm.
USB-C
- USB-C case opening extents include X ≈ 39.370 to 48.570 mm and Y ≈ 82.501 to 85.101 mm.
- Opening center X ≈ 43.970 mm, aligned to PCB X = 0.
- Applied J1 position: (0.000, 35.680) mm, rotation 180°, with the connector mouth toward the top edge.
Verification status
- The exact requested mechanical anchors have been read back after mutation:
- SW1–SW11 are on the STEP-derived MX grid in the 3+4+4 layout.
- ENC1 is on the right circular encoder opening.
- J1 is centered to the USB-C opening and rotated toward the top board edge.
- No component-outside-board, component-body-overlap, overlapping-copper, or ground-return-loop checks are currently reported for the selected review set.
- Airwires remain intentionally unresolved because routing is deferred until the mechanical placement is approved.
Open mechanical assumptions
- The case provides a 4×3 MX grid but the electrical design has 11 switches plus one encoder. The current assignment intentionally leaves the top-right MX cutout unpopulated and uses the right circular opening for the encoder, matching the user's photo.
- ENC1 uses a PEC11R/EC11-style substitute footprint. A final physical fit check against the actual encoder part and knob height is still required before manufacturing.
