Altium DEMO

This is an AllSpice demo showcasing the Archimajor board. With this repo you can explore all the functionalities and compatibility of AllSpice with the Altium ECAD tool .

Board is an all in one 3D printer motherboard. It is an original RAMBo style design with the 32bit Atmel SAM3X8E processor (same as Arduino Due) and TMC2130 stepper drivers all on one integrated PCB. Archim is named after the mathematician Archimedes. The RAMBo stands for (R)epRap (A)rduino-compatible (M)other (Bo)ard.

UltiMachine is a leading 3D Printer component manufacturer. They develop systems that drive additive manufacturing. Specializing in electronics and consumables, they service 3D printing manufacturers, researchers, hobbyists and hackers.
