If you have problems with this firmware, do not consult PROVO CRAFT. This firmware was developed completely independently, without any documentation of PROVO CRAFT products, and without any and all original firmware. This firmware cannot read your original cartridges ever.Ĭricut is a trademark of PROVO CRAFT and this firmware is not a PROVO CRAFT product. It may cause permanent damage, and it will certainly void your warranty. This firmware has only been tested on the machine that I have. Original firmware cannot be restored through any PC application used for normal firmware upgrades. Original firmware cannot be copied from another machine (it has been locked and cannot be read from the CPU) Merged pull request from Gary Stofer to improve HGPL reliability Still have to perform testing because my machine is currently not responding to button or dial changes, so either the code is flawed somewhere or my machine is (which is not impossible, as I have had it opened and mistreated it with a soldering iron several times). 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. Cricut cutting machines can be had for about $50 or less on Craigslist.
