Summary

Archim 2 is a 3d printer controller based on the Atmel sam3x8e 32-bit processor (same as Arduino Due) and Trinamic TMC2130 stepper drivers all on one integrated PCB. Archim is named after the mathematician Archimedes.

Differences

The main difference from Archim 1.0 is the Trinamic TMC2130 drivers. Except for the drivers, the pin mapping and all the other aspects of Archim v1.0 are the same.

Firmware

Requirements

  • Install TMCStepper library: Arduino IDE-> Sketch menu -> Include Library -> Manage Libraries -> install TMCStepper

Marlin 2.0 Configuration

USB Driver

  • Windows 10, Linux and Mac use CDC interface and have hardware driver built in.
  • Windows legacy can use hardware driver: File:RAMBo USBdriver.zip

Troubleshooting

Lost COM port after flashing: Flashing the board using the Arduino Due core will cause the USB to not function. To fix perform a manual erase
