One of NYCR’s most popular weekly classes is in using our Epilog mini-35 laser cutter. The only supported system is Windows with CorelDRAW and Epilog’s closed source driver, which doesn’t seem right for a hackerspace. Luckily, AS220 Labs has figured out how to talk to the Epilog using PJL. I’ve written a command line tool, epilog, that will translate the Postscript file into commands for the cutter. There are a few differences from Epilog’s driver — the most significant is that with the epilog command line tool the home position is always the upper right of the page, not the center of the bounding box as in the Windows printer driver version. The other major difference is that the lines to be cut are distinguished by color, not width: anything that is #FF0000 will be translated into a vector cut.
To use it from inkscape you will need to write out a Postcript file by selecting “Print to file” and writing the output.ps file. Then you can run it through the tool like this…
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

I never thought a for loop would come in handy in shop class before.
