Online G-Code editor, JSCUT

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

Lion battery repair

 

brand new fancy “drop in” lion battery intended to be used for home generator start battery.

 

Failed out of the box, with no support from the manufacturer.

 

out comes the dremel.

 

 

 

These look bigger than the 18650 cells.  Could these be the newer tesla cels? 21700 or even 26650?
