  • It is meant to work with Mellow Fly Super8 board with TMC5160 HV on XY and TMC2209 on E and Z

Note for Super 8 Pro with STM32h723 Chip:

If you are having random MCU disconnection/shutdown, please switch to software SPI, by commenting out the "spi_bus: spi1a" line on each 5160s section and uncomment those 3 lines:

  • spi_software_mosi_pin: PB5
  • spi_software_miso_pin: PB4
  • spi_software_sclk_pin: PB3

DISCLAIMER

  • The macro files are REQUIRED for our printer.cfg to work with klipper.
  • Its also REQUIRED to add a "Linux Process" to klipper, See the "Install the rc script" and "Building the micro-controller code" section [https://www.klipper3d.org/RPi_microcontroller.html]

Macros information: DO NOT USE THE SPEED MACROS WITHOUT READING THIS.

Speed Macros Explanation

Explanation:

  • 1st line: Steps << number of times it will do the stop and go, 100 times in the below case>>
  • 2nd line: Velocity/Speed << The speed/velocity at which you want to test. 1000mms here>>
  • 3rd line: safety distance << the safety distance in mm that the print head will not go from X max and Y max defined on your printer config>>
  • 4th line: Starting Accel << the starting acceleration value for the test. 10K here>>
