TRAMS is a derivative of the popular RAMPS board and is build to work with an Arduino Mega Board. We developed a Marlin variant that uses the internal ramp controllers of TMC5130 and thus relieves the MCU from the task of generating the step pulses.

We will solve the “double step” problem all available open source printer solutions have. In addition TMC5130 comes with the absolutely silent stealthChop™ mode and will make the printer as silent as it can be.

Of course the board will be open source hardware and the firmware will be given back to the open source.

TRAMS is based on 4 TMC5130 cDriver – a Stepper motor driver with integrated ramp controller, so it offloads the AVR and reduces interrupt load to 10% of the original load.
