This is documentation of my work and questions throughout the semester
INPUT LINK OF ROB’S VIDEO
FUSION 360- where 3D modeling takes place, professional software
each Gerber is one layer of your board
NC drill file places and poits on board where drill bit needs to be
G code language for *CNC machines
insure units are the same, in millimeters
Offset will bring it away from corner
FIX: have zero as offset it will be easier over, ou can choose starting point
Thickness is important so it doesn’t cut through too much and so it doesn’t barely scratch surface
Copper Carbite
Gerber file
V bit- v shaped bit, cuts down to make correct cut width
Cuts trouph around circuit
you can increase size for more isolation
Copper Carbide only has drill bits, can’t make slots
LAYERS
SAVE & EXPORT
While you can export another Gerber, let it create in Carbide Copper
can save all the G code filse together as one
or you can save them seperately into a zip file (this always feels safer)
WHY NOT TO USE COPPER CARBIDE
weird shaped boards
any slots
lots of diff size hold
cutting in one pass is a little to much for machine or what you are looking for
OTHER PROGRAMS
easy EDA browser
keycad (notibaly good)
Circuit board form: one side copper, other side fiber glass
design rules check- just makes sure you are not breaking any rules, anything too small or things too close together
factory check make sure they can make it before being sent over
Distance between circuit pins how far pins on sensors, and ho far breadboard pnis are
2.54 millimeter
.1 inch
Clean and rub surface to roughen texture, get rid of finger prints, solder will want to roll off of it
501 60 degree V
You can make big holes to fit things, but slots will allow things to fit perfectly and cleanly
WHERE THINGS ARE: end mills (cut out the board) and are on top of the cutter, most *other circuit things are in metal drawer cabinet under cutter
end mills are extrememly sharp and fragile, be aware when tkain gout so it doesnt cut you or fall and break
make sure to close machine
quarter inch before the cutting part
use wrenches, small on top big on bottom, no need to do super tight, just snug
You want it to start inside the material not right on the edge, especially when there is no offset, establish X and Ys
Do not use fast setting near the material
once things are lines up, loosen bit got it to ease down and such the material
Fun Tip: there is a bit of resistence to untighten, this is non purpose to keep it from falling, but you can work with it
when finishes adjusting set everything at zero and run
load new tool to rerecognize the new position
use spindle to test if it is touching, check for dust if it cuts through
BIG PROBLEM the spindle did not turn on while cutting and did not cut into the materil, reason to not trust Copper Carbine might just use other program Rob knows
EDA PRogram we will use : http/mods.eda.mit.edu/
EXTRA NOTES:
Needs something big to happen? IoT Power Relay, control standard outlet devices with a microcontroller
