Archim v2.0

Archim 2.0a

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.

Specification

• CPU: atsam3x8e
• Drivers: Trinamic TMC2130 (5x)
• Everything else the same as Archim 1.0a
• Mosfets: 4 high power and 2 low power.
• SPIFLASH: replacement for EEPROM.
• USB Isolation: ADUM4160.

Status

• Development Status: First batch prototypes of 2.0a hardware were run and available for Marlin Developers or Early Adopter Documentation Contributors.
• Still needs testing and firmware development.

Firmware

• Currently there is a working Marlin firmware called Marlin4due here: https://github.com/ultimachine/Marlin4Due/tree/Archim2
• Use the git branch "Archim2"
• Requires archim arduino addons.

USB Driver

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