pcb-tools

PCB tooling written in Haskell. This library provides Gerber RS-274X and Excellon parser, as well as some other useful programs generally used in PCB Milling hobby industry, locally in Brno hackerspace base48.cz.

Programs

drillmerge (work in-progress)

Rounds diameters of the holes to available drills. Current strategy is regular rounding.

drillmerge --drills 0.8,0.9,1.0,1.1,1.2,1.4,2.0,3.0 --tolerance 0.1 drill.drl

Suggested features:

• --drills 0.8,0.9..1.4,2.0,3.0
• ability to define whether to round up or down for each drill --drills 1.0,1.4,2.0+,3.0- (or whatever better)

drawgerber

Mock-up parsing gerber file and drawing to file. Uses diagrams.

stack exec -- drawgerber --width=400 -o test.pdf

Currently has some perfomance issues O(2^n) :/

generategerber

A generator of sample random gerber files for testing performance.

stack exec -- generategerber --count 200 generated/sample1.gbr

gcoder (work in-progress)

pcb2gcode alternative (with fixed thermals!), not quite done, will come after drawgerber outputs valid diagrams for all edge cases

Install

Install stack and run stack install

Goals

• Try LBNF complete Alex/Happy parser with EBNF grammar
• Attoparsec parser for Gerber format
• Understand monads
• Use monads
• Gerber interpreter/exporter
• Excellon parser / interpreter
• drillmerge
• Outliner & G-Code generator

What's missing

• Aperture macros
• Polygon definition
• Circular interpolation mode
