Robots and Ink
So I am now using a CNC machine to operate the stamp. For this I manually wrote the g-code (see below) using NCPlot. I must say, NCPlot really speeds things up.
Here you can see the CNC acting as a robot to stamp my cards. So I’m able to make plenty of cards quickly.
I also considered writing on them with a pen using a robot. To test this I attempted a portrait. I brought a photo into GIMP, cropped it, increased contrast and shrunk it down a bit. I then brought it into Inkscape and did an image trace on it. From there I used a laser plugin to convert the curves to g-code. I came across this technique by reading this DIY laser from hardboard and this one that uses an old blueray. I tested and verified the g-code using NCPlot, then finally loaded the g-code into Mach3 to run it on a CNC machine. I used a glue gun to stick a pen to the CNC machine.
The g-code came out like this:
(initialize machine to absolute, inches, XY plane)
(dip in ink)
G00 X14.5000 Y1.0000
(stamp in place)
G00 X1.75000 Y1.0000
(and so forth…)
I alternated back and forth between the ink and stamp sections. On the stamp sections I just in the coordinates of all the locations I wanted stamped. Worked like a charm.
I can see this standing in for a while to keep my business cards coming.
What to do to improve next?
