PCB production

After making hunreds of boards with PCB Express…. we grew out of them. They offer a very easy to use interface, walled garden approach. expensive boards.  Something like 5 x the industry average.

 

I finally found EasyEDA.  It is simple enough for my pea brain to operate.  Lots of libraries built in.  3D view. Direct to JLCPCB to fab  boards.

 

 

We shall see how the quality works out.

Online G-Code editor, JSCUT

New recommendation as of spring 2022, untested.

MakerCam was the easiest to deal with.
It is dead with the death of flash.

 

http://jscut.org/jscut.html# seems pretty easy to use.
Starts from SVG, watch the upper right corner for promts….
Gcodes that are added to the output file.

S100 ;set spindle speed
M3 ;turn on spindle
M5 ;turn off spindle

For 7X Coupling, the set up is:
turn cutter DIA up to .126
.2 pass width, gcode units inch, Xoffset – Y offset =0.
create operation pocket .125
cut the last block of code and put it at the end

December  2020 steps for face cut:
use OODraw to generate svg
JSCUT has difficulty “Picking” objects with no FILL.
so solid fill all objects with black, and line black
ARRANGE order seems to matter,
so if there is a bounding box, send to back

intuWiz software was used for some other cut files with simple shapes
