first github expierence so formatting isnt great, this purely created as reference for my future self, but shared as it may help someone.
#################### Install via KIAUH ####################
Use KIAUH to install klipper, moonraker and Fluidd as normal https://github.com/th33xitus/KIAUH
following prompts there isnt anything different except the following changes.
############### TMC2209 ###############
Intial setup for SKR1.4 is set to Tmc2208, need to change to Tmc2209
The following paragraph needs to be inserted after each stepper & changed as the name of each stepper (extruder, x, y , z) inside printer.cfg:
[tmc2209 extruder]
uart_pin: P1.4 # every different stepper has a different uart pin, although by changing resistors on each stepstick its possible to address 4 drivers on one pin
interpolate: true
run_current: 0.5
hold_current: 0.25
sense_resistor: 0.110
stealthchop_threshold: 0 # 0 to force SPREADCYCLE / SET TO 999999 TO force STEALTHCHOP/ set 100 to switch from STEALTHCHOP TO SPREADCYCLE AT SPEEDS ABOVE 100
############################### BLTOUCH with an AC heated bed ################################
Bltouch uses a Hall-effect sesnor which is prone to noisey signals at the influence of an AC heated bed, so use HOMING_HEATERS on Z axis to reduce interference at the expense of the bed cooling whilst doing bed mesh, so keep to a small sample size 3x3 opposed to 11x11, and use fast travel speeds along x,y axis.
to be inserted in printer.cfg:
[homing_heaters]
steppers: stepper_z
heaters: heater_bed
POSSIBLEY LOOK AT HOMING OVERRIDE INSTEAD OF SAFE HOMING TO LIFT Z TO STOP BLTOUCH COLLISIONS
################ Display on CR10s #################
on original board the display uses 2 ribbon cabbles on EX1 & EX2 but to get it to work with SKR1.4 use a single cable from EX1 to EX3 on display an Ender3
to be set in printer.cfg:
[board_pins]

########################## ORANGEPI-4 CPU TEMPERATURES ##########################
the below values work for orangepi4, I have orange pi zero lts commands elsewhere will add them here soon. to be inserted in printer.cfg:
[temperature_sensor orange_pi_1]
sensor_type: temperature_host
min_temp: 5
max_temp: 100
[temperature_sensor orange_pi_2]
sensor_type: temperature_host
sensor_path: /sys/class/thermal/thermal_zone1/temp
min_temp: 5
max_temp: 100
########################## resonance using adxl3455 ##########################
RESONANCE MEASUREMENT USING ORANGE PI 4
Orange PI differs from Raspberry pi in GPIO pins and SPI names so changes need to be made.
https://neonaut.neocities.org/blog/2018/orange-pi-i2c-spi-setup.html
Enabling SPI
Enable the hardware through config:
sudo armbian-config
switch on SPI in System>Hardware>SPI-spidev & save
Update /etc/modules:
sudo nano /etc/modules
to include the following line:
spi-dev
Update /boot/armbianEnv.txt :
sudo nano /boot/armbianEnv.txt
to include the following:
param_spidev_spi_bus=1 #origianl is 0 but the resonance measurement.py module expects 1 so easier to fix here
param_spidev_max_freq=100000000
The commands to verify the SPI bus should return output like:
$ ls /dev/spi*
/dev/spidev1.0
$ ls -l /dev/spi*
crw——- 1 root root 153, 0 Aug 25 11:05 /dev/spidev1.0
$ lsmod | grep -i spi
spidev 20480 1
Connected pins on ORANGEPI4:
reference to ORANGEPI4 MANUAL PAGE 75
http://www.orangepi.org/downloadresources/
SCROLL DOWN TO ORANGEPI 4 MANUAL , SELECT GOOGLEDRIVE
orangepi4 ---------------ADXL345
pin 2 5V vcc
pin 9 GND gnd
pin 19 SPI1_TXD sda
pin 21 SPI1_RXD sdo
pin 23 SPI1_CLK scl
pin 23 SPI1_CS cs
ADXL345 markings may be slightly different, tx on pi should go to rx on adxl & rx on pi should go tx on adxl the rest should be straight connections

other changes from klipper website which is for a raspberrypi include:
Armbian will only work with Python3, unless we find an older version we have to use this workaround:
sudo apt install python3-numpy python3-matplotlib
we need to edit ~/klipper/scripts :
nano ~/klipper/scripts/cal.py
change:
#!/usr/bin/env python2
to:
#!/usr/bin/env python3
(this will allow numpy matp-lotlib etc to work ,there may be other *.py *.sh apps that also need to be setup to run python3)
to be inserted into printer.cfg:
[mcu rpi]
serial: /tmp/klipper_host_mcu
[resonance_tester]
accel_chip: adxl345
probe_points:
150,150,20 # an example
[adxl345]
cs_pin:rpi:None
spi_speed: 5000000
spi_bus:spidev1.0
######################## WEBCAM section #######################
WEBCAM /dev/video*
seems to bounce around in number from 0,2,3,4 maybe issue with usb and mjpegstreamer?? used some other streamer on octocitrico?
to be inserted/changed in webcam.txt:
camera="usb"
camera_usb_options="-d /dev/video0 -r 640x480 -f 10 -rot 270"cameravideo* to /dev/video0
then "-d /dev/video0 -r 640x480 1-f 10 -rot 270"cameravideo* to /dev/video1
"-d /dev/video0 -r 640x480 2-f 10 -rot 270"cameravideo* to /dev/video2
create copies of webcam.txt and rename to webcam1.txt,webcam2.txt,webcam3.txt .... etc
cd ~/klipper_config/
cp webcam.txt webcam1.txt
cp webcam.txt webcam2.txt
cp webcam.txt webcam3.txt
use fluidd to edit each webcam*.txt
change camera="auto" to camer="usb"
uncomment
camera_usb_options="-d /dev/video0 -r 640x480 -f 10 -rot 270"
and starting with webcam.txt increment /dev/video* to /dev/video0
then edit webcam1.txt to /dev/video* to /dev/video1
then edit webcam2.txt to /dev/video* to /dev/video2
then edit webcam3.txt to /dev/video* to /dev/video3
that seems to cope with the random assigning of numbers to webcam, atleast untill I get more time to look at the problem.
################## end of changes #################
things to do:
sort out webcam t edit o a stable ntod wiringop or op.gpio to enable relay to shut off printer and power switch localy to turn printer on for maintenance
sort out add switch tton pitoded files :
sort out
that seems to cope with the random assigning of numbers to webcam, atleast untill I get more time to look at the problem.
included files:
printer.cfg
bltouch.cfg (had to include Z homing offsets within printer.cfg as SAVE_CONFIG only writes updates if it can find settings inside printer.cfg)
kiauh_macros.cfg
extruder.cfg (had to include extruder within printer.cfg as SAVE_CONFIG only writes updates if it can find settings inside printer.cfg)
