stepper-ninja

An open-source, free, high performance step/generator, quadrature encoder counter, digital input/output, pwm interface for LinuxCNC using W5100S-evb-pico or pico + W5500 module.

You definietly not need this to work with the ninja, only a W5100S-evb-pico or a normal pico + W5500 module and a cheap printerport breakout board!

Features

• communication:

  • W5100S-evb-pico UDP Ethernet. https://docs.wiznet.io/Product/iEthernet/W5100S/w5100s-evb-pico
  • pico + W5500 module (need same wiring as W5100S-evb-pico)
  • pico2 + W5500 module (if you use pico2 board with 48 GPIO you can use the extra GPIO now)

• step-generator: (max 8 with pico 1, max 12 with pico2) 1Mhz per channel. pulse width set from hal pin (96nS - 6300 nS).

• quadrature-encoder: (max 8 with pico1, max 12 with pico2) high speed, zero pulse(index) handling.

• digital IO: you can configure the free pins of the pico to inputs and outputs.

• pwm: you can configure 1 GPIO for the pwm signal (1900Hz(16bit resolution) to 1Mhz(7bit resolution)) and can configure active low or active high

• Software:

  • LinuxCNC HAL driver supporting multiple instances (max 4), with safety functions (timeout, data checks).

• Open-Source: code and docs under MIT License.

• ready-to-ride: w5100s-evb-pico and w5500 + pico version prebuilt uf2 in the binary directory. To install the hal driver you need to run the install.sh in the hal-driver directory.
