Using a smaller build sheet then the actual bed size.
I have a vcore 3.1 500mm and found a deal on some 470mm PEI build sheets. It there an easy way to modify the printer settings to use this smaller sheet so the start print will probe and print in the center of the smaller sheet?

Change Toolshift during VAOC
Ok, so my issue is that I have a much smaller IDEX printer I've been working on building and I'm finally working on getting the IDEX part up and running. It is a roughly 200mm machine with dimensions that would be similar to a VC4 300mm, just 100mm less.
I've managed to adjust almost all the variables I need to run RatOS on a 200mm "VC4" machine, but during VAOC when switching toolheads, it clearly assumes I have more area in the X direction than I do. So when switching between T0 and T1, the toolheads hit the frame, skip steps, and result in VAOC tuning being impossible.
I'm terrible with coding, but I think I found the macro I need to change - [gcode_macro _VAOC_LOAD_TOOL]...
Option 'max_accel_to_decel' is not valid in section 'printer'
I did a software update and getting the 'max_accel_to_decel' error in Klipper. See the other posts about this option depreciated and to be changed to minimum cruise ratio.
Found 3 reference to the max_accel entry in the printer.cfg in the /config root folder. 2 under Base Setup and one under the Stepper motor, drivers, speed limit section. Changed them to the minimum cruise ratio, save restart, reboot, power down/up. Still getting the error. Example of the section in the printer.cfg file entry below. Not sure if the setting is not replicating to other config files or maybe missing another location to update. Could use some help hear please?? ideas??...

abs(): 'Undefined' Error
Hello! New to RatOS, somewhat familiar with Klipper. Just set up the printer (INDEX) and am getting this message when I try to print:
Error evaluating 'gcode_macro START_PRINT:gcode': TypeError: bad operand type for abs(): 'Undefined'
As far as I can tell is comes to this line here under the RatOS/macros.cfg - [gcode_macro START_PRINT]...
Solution:
Fixed it? I re-entered the configurator wizard and skipped all the board flashing stages.
EBB42? Which version?
I’m currently building a RatRig together with a colleague for the first time. After we apparently finished the assembly, we moved on to the configuration. Now we’re supposed to flash the two toolboards, but we can’t really figure out which board it actually is. Based on the layout (compared with the pictures in the OS), we’re leaning towards the EBB42. However, it’s completely unclear whether it’s version 1.0, 1.1, or 1.2. How can we find this out? Honestly, the “experience” of building and comm...
Chamber heat in Orca Slicer causes extruder undertemp in start macro
Hello, I would appreciate some help interpreting this error. I have been manually using my chamber heater, but I would like to use RatOS control. I have tried to set up my heater per the docs.
However, using the same model, I toggle chamber temperature and get an overtemp error.
Driver overtemp error was because I had my fan off to look at wires....

troubleshooting toolboard usb issue
Dear all , I'm looking for help.
I'm using this toolboard from bigtreetech onto my voron 2.4 r2 https://bttwiki.com/EBB%20SB2209%20USB.html
I'm having issue during print ,after fews minutes klipper lost comunication with the toolboard. So far within the documentation grounding of the steppper motor requested/done, the heatsink installed; no information found inside documentation where to install, 2 spots possible.
After adding a fan onto the pcb tool head i'm able to print for about 20 min now.
I'm not sure it is a heat problem related, or pcb issue or usb cord/conection/interference?...
Solution:
well, i've replaced the cheap usb-c/usb-a cable provided with the board, seems to do the trick. I was able to achieve a print of 52 min without issue!
Brostrend not working with webcam.
I have a Pi 3 1GB(into VCORE 3.1) which I can connect with fine, until you plug in the webcam. Logitech standard. IT works fine but maybe robs alot of power? It switches off or interfers with the required wifi dongle to pick up printer wifi from the shed.
The blue LED on the dongle comes on but doesn't flash like it should transfering data. Can't see it on the netwatcher either.
Is it a power or CPU issue? Thinking of getting either a new pi or a powered dongle....
Moonraker auth in RatOS configurator?
Howdy,
I'm running latest RatOS with Fluidd and I have auth set up in Moonraker.
Everything works fine except RatOS configurator (including RAT tool, VAOC etc) which obviously fails connecting to Moonraker....
What Config Settings for Rapido 2 UHF?
When I set up my /config file, the only options under Rapido 2 are CHT or Regular. But I have a UHF. Am I doing it wrong?
Solution:
Maybe share a screenshot, but I think UHF is assumed, and the question is just asking about the nozzle type
Flash control board via DFU
Hey, currently attempting to do the initial flash of the control board. I've followed the documentation to flash the RiPi and update all the packages in the proper order, however when I'm on the control board step of the wizard it's just stuck on "Waiting for DFU". The correct board is selected, the jumper is set and the board status light is now solid instead of blinking so I assume it's properly in DFU mode, but seems it's just not communicating? Under the electronics section of the build gui...
Ratos gives "connection denied" error even when connected with wifi
So I'm setting up my ratos on my RPI (which is connected with ethernet) and it sends off a network wich you can connect to (as it should be). But after connecting and searching ratos.local, http://RatOS.local/configure or http://192.168.50.1/configure it just gives the "ERR_CONNECTION_REFUSED" error.
Solution:
Im coming in late to this, and only skimmed, but I've heard from others that the rpi imager is okay as long as you don't change any of the defaults, and to use balena etcher 1.18 or earlier.

Unsupported board - how to get thru the configuration wizard?
Hello all,
I run my VCore3 on Klipper for long and because I want to switch to a dedicated RaspberryPi2 for my printer (instead of my Pi4 homeserver running many things additionally) I tried the RatOS image. Works nice so far, but I cannot get past the configuration wizard because my board ( Mellow FLYF407ZG with Stm32f407zgt6 ) is not supported.
While I can get RatOS / Mainsail to work by replacing the printer.cfg with my established one, I cannot use for example the Realtime Analysis, because when I try to, I am redirected to the Configurator.
...
Solution:
For starters you will need to compile the board firmware manualy using the data from Mellow for it.
Then you can skip the board selection by changing the name on the address bar. Is there is something ended by 1, change to 2. Of 2, change to 3. Etc
Then you need to use the user override section to give klipper the propper pins for everything....
Ratos.cfg restoring default values after printer reboot
Hello, I have a Ratrig V-Core 4 500 and i want to modify the run_current (actually at 1.6) in some steppers, because I keep getting an OTPW flag in X and Y drivers. If i change it to 1.3 I don't get the flag. How can I change it permanently? Or is this something I don't have to worry so much? My printer is enclosed, I plan to work with ASA and nylon so it's going to be hot inside the chamber.
Thanks in advance!...
Solution:
I solved it! Thank you so much. I copied the section from the RatOS.cfg to the printer.cfg, and added the values I need. Thank you!
