Compiled with Atmel Studio 7, all compile errors resolved and verified it uploads to the machine and runs. Updated the project settings and files to include contributions from Gary Stofer, for his Cricut Cake Mini machine that uses a different display and button layout, as well as GCode parser. So in reality, you get a fairly decent XY controller board with a PWM output for solenoid or laser control for cheap! One of my future plans are to put a laser diode in place of the knife holder and see what I can do with it. The stepper motors are controlled by eight mosfets. Additionally, an onboard USB port and the Atmel ATMega1281 chip running at 16mhz provides all the horsepower you would need. They typically contain wheels that control speed, pressure, and other settings (one of them is usually an optical encoder, the others are potentiometers), a display of sorts, and a keyboard that has a ton of fairly useless buttons with green LED backlights. They contain two stepper motors, a moving solenoid powered knife holder that generates 12 volts to the solenoid using PWM. THERE IS NO WAY TO GET THE ORIGINAL FIRMWARE BACK OTHER THAN BUYING ANOTHER MACHINE.Ĭricut cutting machines can be had for about $50 or less on Craigslist.

IMPORTANT: REPROGRAMMING THE CPU WILL PERMANENTLY ERASE YOUR ORIGINAL FIRMWARE Open Source firmware replacement for Cricut(tm) Expression and Cake stencil cutter machines.
