How do I use my cartographer for input shaping?¶
Note
These instructions do not apply to Simple AF for RPi, although it is certainly possible to use the Cartographer as ADXL on non creality printers.
This just needs a few changes in printer.cfg
You need to modify the [adxl345] section
First of all change the cs_pin from nozzle_mcu:PA4 to scanner:PA3
Then disable the following settings:
spi_speed: 5000000spi_software_sclk_pin: nozzle_mcu:PA5spi_software_mosi_pin: nozzle_mcu:PA7spi_software_miso_pin: nozzle_mcu:PA6
And add the following settings:
spi_bus: spi1axes_map: x, y, z
So your [adxl345] should look like:
[adxl345]
#cs_pin: nozzle_mcu:PA4
cs_pin: scanner:PA3
spi_bus: spi1
#spi_speed: 5000000
axes_map: x, y, z
#spi_software_sclk_pin: nozzle_mcu:PA5
#spi_software_mosi_pin: nozzle_mcu:PA7
#spi_software_miso_pin: nozzle_mcu:PA6
I do not know if this is a good idea, I just know it's possible!
