Adaptive Bed Mesh

I just purchased a Vcore 3.1 on the cheap that was not assembled verdy well. I have been going through the build including the wiring to finally arrive at printing. The Pinda probe seemed inconsistent so I upgraded to a Euclid probe. Homing and z tilt go well but a problem with adaptive bed meshing. With the pinda probe adaptive bed mesh went ok but with the euclid probe once a print was started and z tilt was done, the toolhead would go to the center of the bed and do a probe that seemed to not recognize the probe then move to the purge blob spot but did not lower the bed and proceeded to knock the probe off. Not expected. I have now returned to normal bed mesh ( no adaptive) and that probes with the Euclid probe fine except I originally had an error "horizontal_move_can't be less than probe's z_offset". My online search found a fix by adding [bed_mesh]...

Board flashing error

I am trying to flash the octopus on my V3.1 and i keep getting Octopus V1.1 detected but is unresponsive. Klipper doesn't seem to be running on your board, which may indicate faulty firmware or a faulty board. Please check your board and try flashing it again. ...

variable_hotend_heat_soak_time as slicer variable?

Would it be possible to have variable_hotend_heat_soak_time change depending (for instance) a variable in the slicer? As I often print quite some stuff, consecutively, it happens a lot that i have the hotend heater on (as a result of a filament change) or that I just finished one print and want to redo or start another and as such would like to have a lower variable_hotend_heat_soak_time....
Solution:
SET_GCODE_VARIABLE MACRO=RatOS VARIABLE=hotend_heat_soak_time VALUE=100
SET_GCODE_VARIABLE MACRO=RatOS VARIABLE=hotend_heat_soak_time VALUE=100

No extrusion after the first toolchange (VC4 IDEX 500)

fetch origin

Attempting to update RatOS, as I have done several times before over the past year or so. Pi > Network page says, "Failed to initialize. This panel needs NetworkManager installed into the system. And the appropriate permissions. Without them it will not function. Failed to detect NetworkManager service." Pi is connected to Windows 10 PC via Ethernet cable. PC has very solid Internet connection. Where to find, and how to install NetworkManager, please? Thank you!:ratrig:

Using Raspberry Pi GPIO header pins from RatOS/Klipper

I was just happily configuring an additional chamber temperature sensor (https://www.klipper3d.org/Config_Reference.html?h=temperature+sens#ds18b20-temperature-sensor). The DS18B20 has a one wire interface, which i'd like to connect to the Raspberry Pi that also runs my RatOS. After checking that i get reasonable readings from the sensor via cli&ssh i tried to implement the sensor in my printer.cfg. I struggled when i needed to name the "sensor_mcu" name (which in my case is the Raspberry Pi), because i could not find the name of the Raspberry Pi mcu in the RatOS docs. - Is RatOS implementing the host mcu (Raspberry Pi) as secondary mcu per default? - If yes: How can i refer to the RPi mcu in my klipper cfgs?...

RATOS bug?

H723 reported as f446 in Y endstop. RATOS RC3 reported as RC2. This affect the printer?
Solution:
No. First one is a cosmetic issue, the second one shows 2 different things, the OS image version that you installed and the version you updated to.

BalenaEtcher older versions give malware errors on mac and shutdown.

Since the new versions of balena etcher never work for flashing and I had to resort to older versions to flash ratos2.1 and all of a sudden when I go to redo my chonk the older versions are closing with a malware error and putting the app in the trash. Rasberry pi imager writes the image but I never see ratos coe up in my wifi. With balenaetcher is came right up afterwords but now I cant use it.
Solution:
I found somebody with a windows computer and downloaded an older version of etcher and it worked. After updating everything then running the config my X and Y motors are swapped. Same wire set up where it was running last time

Can't connect to wifi after SSID/Router Upgrade - V-Core 4

We just recently switched internet providers & got a new router (Went from an Erro Pro 6 to a Pro ^E, nearly identical) And I can not get the Pi to connect to a network. All of the mesh basestation show up individually. I have tried to connect to each one with no luck. RatOS network pops up each time. I have disabled 5ghz mode, I have turned on "legacy mode" on the router side, and still nothing. Everything connected and worked fine before this, with the exact same Mesh extenders and same settings. There is also a "\x20" at the end of the SSID that doesn't show on any other device....
Solution:
I have solved it. Apparantly this little part "There is also a "\x20" at the end of the SSID that doesn't show on any other device." was the issue. Turns out the \x20 is the Pi seeing a space at the end of the name. My SSID had an extra space at the end, and the Pi hated it....

Areas outside the print area

The VC4 is different because actual travel is quite a bit larger than the actual print area to accommodate IDEX. If I am using a non IDEX machine, but I want to include gcode to access areas of the printer outside the bed margins, how do I do that without erroring out the print?

Internal (klipper/RatOS controlled) heater

Here I go again... Google could not save me... I have a single Chamber sensor connected to say "PF5" (using example pins). If I dont specify "temperature_sensor chamber", RATOS will use the Extruder sensor, which I dont want as I have a chamber sensor....
