Prunt Board 3: Enhanced 3D Printer Control for Quieter, Smoother Operation (Crowdfunding)

Prunt Board 3

Prunt Board 3 is a 3D printer control board with six TMC2240 stepper drivers, two 15A heater outputs, four fan outputs, four thermistor inputs, and four endstop inputs that is designed to offer smoother and quieter operation. The hardware is said to offer better ESD protection than boards such as the Duet 3 Mini 5+ or BTT SKR 3 EZ and supports hardware-accelerated step generation, but the magic happens with the Prunt firmware and associated server, which enable a 31-phase velocity profile for smoother operation and higher-quality prints compared to boards running Klipper or Marlin firmware. Let’s have a look at the hardware first. Prunt Board 3 specifications: 6x TMC2240 stepper drivers, all capable of running at 3A with minimal airflow 2x 15A heater outputs with short circuit protection (1.3 µs response time) 4x tachometer inputs Fan outputs 4x fan outputs supporting 2, 3, and 4-pin fans, all up to […]
