Rat Os crashes when trying to print large file (440mb)

I'm tring to print a large print, i';m not sure if this is a limitation of my hardware (manta m8p) or ratos the file is roughly 2kgs of filament, 400mm tall (its a bust) it takes an age to slice and upload, but when i go to print nothing happens
Solution:
@James if you update RatOS it will now skip postprocessing if there's not enough memory available on the system to process the file.

Move exceeds maximum extrusion (at primeblob)

I get above error (4 times) while doing a primeblob. Printer (slicer and RatOS) is set for 0.6mm (CHT). I know how to correct this (add max_extrude_cross_section: 5 in [extruder]) but I was curious why this happens. If RatOS is Nozzle Aware...

didn’t get rat OS flashed

I tried with different cards at multiple devices with different image versions but every of them fails
Solution:
If it is a recent Balena Etcher, it had problems. Use .18 version.

Not able to print IDEX

Error when trying to print the first layer test file. Error evaluating 'gcode_macro START_PRINT:gcode': gcode.CommandError: Something went wrong! Missing important post processor start print parameter! Unknown command:"EXCLUDE_OBJECT_DEFINE"...

BEACON COMPENSATION_MESH higher on POA then PEI and Powder coated

I created 9 Bed compensation meshes; -3 build plates (Smooth PEI, Powder coated PEI and POA) -3 temperature ranges The 3 temperature ranges of the POA-plate are all "higher" then the other 6. Is this normal?...

Not able to print with IDEX

I'm getting this error when trying to print: Error evaluating 'gcode_macro START_PRINT:gcode': gcode.CommandError: Something went wrong! Missing important post processor start print parameter! I've added RatoS debug, my printer.cfg and ratos.cfg and the gcode I'm trying to print...
Solution:
Here's how I setup the USBs

IDEX config has T0 for both heads?

I'm not sure if I did something wrong or there's a problem with the configuration

Random Pauses? Please Help!

I am having issues with this print randomly pausing partway through the print. It never stops in the same place and never shows anything in the console. Any ideas what’s causing this? I’m so confused. I re-sliced it and again pauses random places. I have an orbiter filament sensor and a broken sensor that’s wired in, but I have yet to add anything to the configuration.

Problems with Orbiter Smart Sensor

I installed an orbiter smart sensor on the toolhead. Seems to work fine. I configured printer.cfg according to: https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/configuration/filament_sensors.md#orbiter-smart-filament-sensor-example-configuration but shouldn't pressing the button unload the filament? On my machine nothing happens. No heating and unloading of hotend. For testing I changed in my printer.cfg: `[filament_switch_sensor toolhead_filament_sensor_t0]...

RatOS 2 w/ Octopus Pro controller fan?

Hi, I'm using an Octopus Pro on my vCore3.1 and the latest RatOS release. By default what fan port should I use for the always-on board/steppers?
Solution:

'gcode' in section 'gcode_macro RatOS' must be specified

Hello, I was trying to get my adxl working and this has come up. I havent changed any settings so im not sure why its suddendly decided to happen, anyone know how to fix it, cant seem tofind the mentioned item in config.

What causes "toolhead stopped below model range" and what can be done?

@Helge Keck I'm running RatOS 2.1 RC3, and have run the initial beacon cal, beacon_ratos_calibration, and beacon_create_scan_compensation_mesh bed_temp=85 profile=Contact. I've been getting the Toolhead stopped below model range and the Error during homing contact: Contact triggered while accelerating errors. The nozzle height looks normal when I get these messages.

In consistent Z-Height when using bed mesh compensation. Temperature compensation not used

I re-did all my calibrations of Beacon as per Helge's manual from 1 to 5 https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/configuration/beacon_contact.md#6-first-print-and-fine-tuning. At part 6 the nozzle is approx. 0.5mm to high, so I babystep to a proper first layer squisch. Enter SAVE_Z_OFFSET in the console. stop the print. Save_config. I see that the output now says: Beacon model offset has been updated, new value is -0.46781 after restart, the next print is again approx. 0.5 to high and I can repeat this all night. I thought it should report nozzle_expansion_coefficient_multiplier which was then stored in ratos-variables.cfg?...
Solution:
So, Only thing that I can think of is that my reference Contact mesh somehow was erroneous.... or something in the other refference files was off. anyway, now I need to redo all the bed meshes But I think I solved it (by accident, that is)

1 cm shift after pause

When I print an object I get repeatable an exactly 1cm shift to the right when resuming the print. I first suspected a loose belt of similar, chencked the mechanics but can't find anything. Then as I was testing the new Orcaslicer I reverted back to Prusaslicer with the exact same result. Also checking the gcode in gcodeanalyzer.com seems to be as expected. Weird is that printing a primitive with a pause does go allright. In Prusa slicer I had to insert "PAUSE" to trigger the amcro, Prusa inserts M601 which is not picked up by RatOS (Orca inserts PAUSE by default). ...

Do you need to reflash your boards if you move to RatOS

I have a running VzBot triple Z and one to move to RatOS. My boards (Octopus v1.1 and SHT336 Pro(tmc5160) are flashed with lates Katapult and Klipper. All running CANBus. Do I still need to Flash the boards with the configurator, and if not, where are the uuid settings for the boards in RatOS.
Solution:
Thanks for the information. I understand that for some people, CanBus is overwhelming, but so is RatOS. I may end up pulling all the parts needed to run without flashing and keep Canbus

Doing a cold pull with toolhead filament sensor

I find that the unload macros etc cause trouble when I'm doing a cold pull. Ideally, I'd like to be able to disable the unload button (orbiter sensor, easily gets pressed by mistake), and disable filament removal/insertion detection so I have full manual control of nozzle temp etc without anything getting triggered by mistake. Is there an elegant way to do this?

Octopus V1.1 doesn't want to flash / get recognized by RatOS 2.1.X

Hi, earlier during my V-Core 4 build I accidentally installed RatOS 2.0.X. Now I reflashed the SD-Card with 2.1.X, and am trying to configure it. But for some reason no matter what I try, flashing the octopus doesn't seem to work in the configuration wizard. Automatic flashing says there is no board detected. In the DFU overview I can get it to detect it with the BIOS0 header, and then half a minute or so after pressing flash it simply shows the same, initial, DFU screen, as if it did nothing and can't detect it. Pressing "Check Board Status" in the SD-Card section doesn't do anything, when in 2.0.X it did work for me....

Prime Line instead of Blob?

I am getting all sorts of blobs on my print and I wonder if they are coming from the prime blob at the start which engulfs the nozzle that then drags itself out of it. Is there a way to switch this to a line in RatOS?...
Solution:
Prime line was deprecated.

still cant get first layers to be consistent

i'm at my wits end with this printer. im 10 days in and still dont have a first print done. i've been tryin to get my first layer issues sorted out. multiple beacon calibrations later, i'm still getting inconsistencies and non-sticking portions of prints. it's not the build plate, it's clean. the printer is not putting the plastic down close enough to the bed to smush on the external walls, it's constantly all over the place. it's exceedingly frustrating. this printer was supposed to be u...
Solution:
The only conclusion I came to was "maybe my x-rail was not mounted correctly or something"
