klipper-configs file will need to be updated due to recently deprecated options in Klipper

[TheTinkeringSquid]

As per the Klipper changelog (https://github.com/Klipper3d/klipper/blob/master/docs/Config_Changes.md), several options/features have been removed.

"20211102: Several deprecated features have been removed. The stepper step_distance option has been removed (deprecated on 20201222). The rpi_temperature sensor alias has been removed (deprecated on 20210219). The mcu pin_map option has been removed (deprecated on 20210325). The gcode_macro default_parameter_ and macro access to command parameters other than via the params pseudo-variable has been removed (deprecated on 20210503). The heater pid_integral_max option has been removed (deprecated on 20210612)."

The most notable one is the pin_map option. I found your config file very useful, but I just wanted to let you know that Klipper no longer allows you to specify an arduino pinout. Thankfully, it's not that hard to make the required changes, so I will share them here when I am done.

First of all I would like to thank You for an excellent video tutorial on klipperization of CR-10 max 3D printer.
It helped a lot and I have now CR-10 max fully operational.
Nevertheless I would like to point out that I ran into several problems while using the provided printer.cfg file.

1. The command:
   pin_map: arduino
   is not supporter by klipper any more
   Instead I had to paste the following aliases:
   
# Arduino aliases for atmega2560/1280 (Arduino mega) boards
   [board_pins arduino-mega]
   aliases:
   ar0=PE0, ar1=PE1, ar2=PE4, ar3=PE5, ar4=PG5,
   ar5=PE3, ar6=PH3, ar7=PH4, ar8=PH5, ar9=PH6,
   ar10=PB4, ar11=PB5, ar12=PB6, ar13=PB7, ar14=PJ1,
   ar15=PJ0, ar16=PH1, ar17=PH0, ar18=PD3, ar19=PD2,
   ar20=PD1, ar21=PD0, ar22=PA0, ar23=PA1, ar24=PA2,
   ar25=PA3, ar26=PA4, ar27=PA5, ar28=PA6, ar29=PA7,
   ar30=PC7, ar31=PC6, ar32=PC5, ar33=PC4, ar34=PC3,
   ar35=PC2, ar36=PC1, ar37=PC0, ar38=PD7, ar39=PG2,
   ar40=PG1, ar41=PG0, ar42=PL7, ar43=PL6, ar44=PL5,
   ar45=PL4, ar46=PL3, ar47=PL2, ar48=PL1, ar49=PL0,
   ar50=PB3, ar51=PB2, ar52=PB1, ar53=PB0, ar54=PF0,
   ar55=PF1, ar56=PF2, ar57=PF3, ar58=PF4, ar59=PF5,
   ar60=PF6, ar61=PF7, ar62=PK0, ar63=PK1, ar64=PK2,
   ar65=PK3, ar66=PK4, ar67=PK5, ar68=PK6, ar69=PK7,
   analog0=PF0, analog1=PF1, analog2=PF2, analog3=PF3, analog4=PF4,
   analog5=PF5, analog6=PF6, analog7=PF7, analog8=PK0, analog9=PK1,
   analog10=PK2, analog11=PK3, analog12=PK4, analog13=PK5, analog14=PK6,
   analog15=PK7,

Marlin adds these additional aliases

ml70=PG4, ml71=PG3, ml72=PJ2, ml73=PJ3, ml74=PJ7,
ml75=PJ4, ml76=PJ5, ml77=PJ6, ml78=PE2, ml79=PE6,
ml80=PE7, ml81=PD4, ml82=PD5, ml83=PD6, ml84=PH2,
ml85=PH7

2. There is an error in Your printer.cfg in line 86 - the whole line (containing: "Rotation_Distance.md") needs to be removed

3. I ran into some problems with BLTouch not extending from time to time
   and causing nozzle crash into the printer bed during mesh calibration routine.
   The solution for me (so far) was to add in [bltouch]:
   stow_on_each_sample: False
   and changing z axis limit in [stepper_z]:
   position_min: -0.1
   The first limits the number of extensions so a crash is less likely,
   the latter should prevent damage in case the BLTouch would fail again.

4. Also I corrected offsets of BLTouch to:
   x_offset: -27
   y_offset: -3

5. Since I have a standard CR-10 max extruder the dir_pin is reversed:
   dir_pin: ar28
   instead of
   dir_pin: !ar28

6. Also the standard CR-10 max extruder rotation_distance is different:
   rotation_distance: 22.8571
   instead of
   rotation_distance: 7.824

Other than that the printer.cfg file You provided was a great help to start using klipper.

As promised, here is my slightly modified config that I verified with my Ender 3 Pro with a BLTouch as the only HW modification. I am still figuring out multi-point mesh bed leveling. Currently, my BLTouch is sampling a single point in the center of the bed. Lastly, since this is semi-specific to my application, I figured I'd post it here as a text document rather than request a merge.

Hi guys,
Firstly, sorry for the slow respomnse, I don't monitor this repo at all and stumbled upon this issue by chance. Thanks for the input and motivation to get me to update. Some notes:

• There are several printer configs here but I think the Creality 8 bit board based CR-10 Max config is what is being discussed.
• I have updated some parts in the past, like the changes in variables for macros, but have not updated here. The CR-10 Max config has now been updated with this and the change from pin_map. Thank you [KrzysztofKam] for the pin mappings, they saved me some time.
• My printer has a Henera which explains some of the variations in cnfig. i have added this information to the header.
• "Rotation_Distance.md" line must have been a copy and paste error publishing to GitHub, as it wasn';t in my actual Klipper config. Fixed now.
• I also experimented with BLtouch reliability and came to the same conclusion.

Thanks again to both of you :)

Hey, I have some trouble getting a connection with the updatet printer.cfg and my standard cr10 max. Mainsail throws me:

Internal error during connect: [Errno 19] No such device

The Klipper LOG gives me:

i assume it has something to do with

mcu 'EBB': Starting CAN connect

As there are EBB references in pinout I was wondering if you @KrzysztofKam could post your printer.cfg for further debugging.

Kind reagrds

To clear things up, I got everything working, one thing I would like to mention, is that the last commit adds a second controller via can bus, that is why it is not directly working. So I recommend checking the version history and use the version before.
