Klipper Shutdowns

Hi, I have some problems that they seem related: most of the time I get warnings that the z, z_1 or z_2 stepper drivers are too warm. This is not disturbing me too much , but recently I started to get Klipper shutdowns. The first was OvertempError reported by the stepper_z1. The second one was a MCU shutdown (see pics). Both the Octopus Pro board and the Raspberry 4 sit under two large 120mm fans, which are PID-controlled . The temperature is read next to the boards by a special thermistor....

SAVE_Z_OFFSET always saves to beacon model offset

Machine Info: V-Core 4 400 IDEX I am trying to calibrate my z offset as my first seems to be slightly off. I decided to recalibrate my beacon following the steps listed here: https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/configuration/beacon_contact.md The only step I did not do is step 5 (scan compensation). ...
Solution:
No, it's during the first layer. If you end up having to adjust your g-code z_offset so that it's below zero, that's a strong indication that something most likely went wrong. It can be as simple as a dirty or loose nozzle or something more complex like your z couplers (the ones that couple the leadscrew to the motor shaft) aren't tight enough and thus your Z movements are inaccurate.

Error after updating board

I've changed out my board to an Octopus Max EZ v.1 and am getting this error. I can't find the issue. I'm sure it's something I've done wrong, just can't figure it out.

Smart filament sensor for Orbiter v2 configuration.

I'm trying to assist a friend of mine who's further along in his build than I'am. He's struggeling a bit with his Orbiter v2 Smart Sensor configuration and I'm wondering, does the attached picture look correct?

My ratrig V4 can not maintain temperatur stable

Hi my name is Alvaro, I hope somebody can give a hint, I recently bought 2 Vcore4 units, the hybrid one. And I'm having Z wooble problems, because the heated bed and also the extruder thermistors, are going up and donw like a degree after 2 or 3 seconds, i try to do PID tunning 15 times and nothing changes, even with the standar parameter I can not remove that 1 degree fluctuation in both heaters. Any ideas?? I just tested everything that I could, and follow the commisioning guide in the ratrig website, but nothing seams to help?...

How to upgrade from ratos 1.2 to 2.2 ?

Hello, Still running on 1.2, haven't updated for a while...and now I get the screen attached on my printer screen. What would be the easiest way to upgrade my ratos to v2.2 or 2.1 without loosing my presets ?...
Solution:
You will have to reflash, there is no update option to 2.1 RC2.

Nozzle getting closer to bed as it prints first layer

Initial approach of beacon not working when the heated bed or hotend is heating.

I am able to perform the Poke test reliably when the bed and nozzle are cold, but it repeatedly fails when they are warming up.

goop on nozzle after prime blob

I get this a lot. How much depends on the filament, and probably temperature. continuation of conversation here: https://discord.com/channels/582187371529764864/1246562369513984100/1302452251041726549 after an hour of printing most of the filament from the prime blob will have wiped off, though you can see the remains of it still. (see marked image) The excess filament on the outside of the nozzle tends to cause messy first layers as that filament is slowly dragged off during the print....

Load Filament Macro Move Out of Range

When running the load filament macro for T1 from the park position you will get error; Move out of range: 332.800 150.000 15.000 [0.000]

MCU Timing Error

Consistently getting a timer too close error, about 45 seconds into prints- Tried two different pi's, with and without camera attached. V3.1 running 2.1, issue started 2 updates ago.
Solution:
Right then it's possible it's just filesystem corruption. 2 options: 1. Assume it's just filesystem corruption and reflash ratos to current card, then start shutting down the pi properly (you can do that from the menu in the top right in mainsail) 2. Assume it's a dying sd card, get a new one and flash ratos to that and start shutting down the pi properly....

_USER_END_PRINT_PARK Macro misbehaving

W have a macro that should reset extrusion factor and printspeed back to 100% and also clear the skew profile, like so: ``` [gcode_macro _USER_END_PRINT_PARK] gcode: M220 S100 ;set printspeed back to 100% in case I have tweaked it during printing...

Need config help on adding a section for a second part fan

hello. this may be a stupid question but couldnt find an answer for it. I have installed a Aux fan in my V0 and couldnt seem to figure out the config to add it to the printer. i tried naming the fans differently to stop klipper freaking out. Is there a proper way of adding a second fan in the same section as my part fan but supplying power from a different port? (simplified- What text do I add to config to add an AUX part fan with power from a different port than part cooling fan.)...

IDEX Misses Z moves

I star to test dual material printing but I encouter one issue. I tried to print this minion but when there is tool change that has little to no outter walls the printer doesn't move on Z to make the layer change. It's strange because at the lower layers of the minion it's working fine. I checked the gcode from OrcaSlicer and the layer change is there. It seams like the post processor is removing it or the printers is skipping it for some reason....

Print freezes, unrecoverable.

Came home last night to the printer in a frozen state. It was not pasued but it was not printing. I was about three layers into it

TMC ‘extruder’ reports GSAT

Hello, My printer keeps throwing this error at 95% or so of a 24 hour long print. I attached a picture below to show. Any idea what’s causing this? I checked my wiring and it’s all fine looking. Also, the print started looking bad before this error. And ideas?...

Installing RatOS on BTT Pi2 and octopus pro v1.1 h723

Hello, I have bought a BTT Pi 2 and I wish to use Obico in conjunction with RatOS. The images available don’t seem compatible so I assume that I will need the image for the BTT Pi 2 and then ssh in to use the RatOS configurator repo to use them together. Is this the correct method to reach my end goal? This has been a bit of a learning curve and am not sure if this is the correct path....
