Repo for pcb layouts, gerber and gcode files

Ki-Cad

PCB layout:


Use as wide traces as possible. 1mm preffered.
Dont use "filled areas" if possible. It does not make good geometry in flatcam
Don't forget to set origin marker
Export gerber: use auxiliary axis


FlatCam

geometry generation:


If you are using thru-hole components or using bottom layer, mirror around y axis for both geometry and Drilling
Edit drill files if necessary for fewer drill sizes
TODO: test double sided layout by mirroring around center axis!


Isolation generation:


Current isolation mill depth to test: 0.04 mm (0.05 was tested and seems to work fine!) (Common copper depth is about 0.03 mm)
Current feedrate on isolation milling to test: 60 mm/s
spindle speed 12000 rpm
use 0.2 mm tool width on cnc generation
2 passes with 0.1 overlap


Cutout generation:


Current cutout mill depth: 1.6 mm
Current feedrate on cutout milling: 40 mm/s
spindle speed 12000 rpm


FlatCam defaults:


put a link in ~/.FlatCAM/defaults.json


bCNC

Probe:


Fastfeed: 120
Probefeed: 25
Probe points: 4/cm (in each direction)


Drilling:


Current drill plunge rate to test 20 mm/s
spindle speed: 12000 rpm
Drill depth: 1.6
