Worked for 2 mins 56 sec
Blocked: I cannot create a true internal Edge.Cuts routed slot with the available PCB edit tools in this session.
What I did:
- Removed the earlier pad-style NPTH slot, because you clarified it must not be a pad or drilled hole.
- Did not resize, move components, reroute, or modify copper.
Current DRC after cleanup:
- Airwires: 0
- Overlapping copper: 0
- Floating copper / invalid layer / missing footprint errors: 0
- Remaining: 3 pre-existing dangling-trace warnings.
Why blocked:
- The available line/shape tools only support Top/Bottom layers.
- The board-outline tool supports a single closed board outline, not a separate internal Edge.Cuts milling path.
- So I cannot safely add the requested internal routed slot as true Edge.Cuts geometry from here.
You’ll need to add this one slot manually in the PCB editor / manufacturing mechanical layer:
- Centerline: X = -8.5mm
- Start: (-8.5mm, -60mm)
- End: (-8.5mm, +60mm)
- Routed slot width: 2mm
- Non-plated milling / Edge.Cuts layer.
Export the current Gerbers without the slot, and clearly note the manual slot requirement for fabrication.
Thought for 7 sec
I’ll export the current Gerbers as-is, without the slot, and state the manual milling-slot requirement clearly for fabrication.
Worked for 1 min 21 sec
Exported the current Gerbers without the isolation slot: glecs-v4p1-motor-starter-controller-gerbers.zip.
Manual fabrication requirement:
- Add a non-plated routed/milled slot on Edge.Cuts, not a drill pad.
- Centerline: X = -8.5mm
- Start: (-8.5mm, -60mm)
- End: (-8.5mm, +60mm)
- Slot width: 2mm
- Length: 120mm, leaving 10mm solid board bridges at top and bottom.
Pre-export DRC gate was clean: airwires = 0, overlapping copper = 0, missing footprints = 0, invalid layer = 0.

GLECS V4.1 Project Specification
Objective
Build a 2-layer PCB for a 415V agricultural motor starter controller named GLECS V4.1.
Board
- 200 mm x 140 mm, 2-layer FR4 1.6 mm
- ENIG finish, green solder mask, white silkscreen
- Non-plated milled isolation slot: X=84 mm to X=86 mm, full board height
- Bottom layer solid GND plane
Power
- Input: +12 VDC via J_PWR on left edge
- +4 V rail: LMR33630ADDAR buck for A7672S LTE module
- +5 V rail: AMS1117-5.0 for relay drive and optocouplers
- +3V3 rail: AMS1117-3.3 for STM32 and logic
- AMS1117 parts require 10x10 mm copper heatsink pad and 4x 0.3 mm thermal vias to GND plane
Key Circuits
- STM32F103C8T6 controller, A7672S-FASE LTE modem, ACS712-30A current sensing, LM358 signal conditioning, PC817 optocoupler inputs, relay driver and 415 VAC contact path.
Safety / Layout Constraints
- All 415 VAC copper remains left of the isolation slot
- 3.3 V logic remains right of the isolation slot
- Only optocouplers cross the barrier
- HV net class: 4 mm clearance, 1.5 mm trace width
- Fail-safe: PB5 defaults LOW, relay contacts open, motor stopped; firmware watchdog target 2 s
Build Plan
- Source components and footprints.
- Capture complete schematic.
- Run ERC/design review and fix issues.
- Size PCB, place components by zones, route, run DRC.
- Export Gerbers only after checks are clean.
Important Safety Note
This project handles 415 VAC motor-control wiring. Final production design must be reviewed by a qualified electrical safety engineer and validated against applicable IEC/UL/CE/regional standards before field deployment.
