Hard recovery killed Klipper
Checked updates recently and Klipper displayed the orange invalid config flag. Tried a soft recovery, unsuccessfully, then went for the hard recovery option. This completed 'successfully' in the updater but Klipper didn't seem to survive; moonraker is now displaying the DISCONNECTED error. Is there a way to force a Klipper reinstall? Have done 'ratos doctor' w/o success.
Solution:
Try this, line by line:
ssh to the machine
cd printer_data/config/RatOS
git fetch origin...
PT1000 problem
I am currently trying to print with my RatRig V-Core 4 500, but PLA is not extruding well at 220°C.
When I increase the temperature to 300°C, I am able to print PLA. This probably means something isn’t working correctly.
How can I solve this problem?...

Problem with first layer EXTRUDER_TEMP in COPY and MIRROR mode
When I print in mirror or copy mode, the first layer temp for extruder T1 is set to the settings of filament in slicer... instead of being synchronized with T0 temp. Something to fix in the START_PRINT macro?
VOAC calculating offset wrong by the same amount every time
Just like the title says, my X offset between T0 and T1 is always wrong by 0.9mm in X (Y is perfect). Any idea on what would cause this? My frame square and both toolheads print really well. Skew calibration prints close to perfectly for each.
Belt tension graph interpretation help
I generated the belt tension graph after replacing the idlers, belts, and pulleys (They were due for a change) and was wondering how to interpret the graph. I've always used the Gates Carbon Drive frequency analyzer to measure the frequency of a 150mm section of the belt in the past, and it has worked somewhat ok for me. I figured since RatOS comes with a belt tension measurement macro, I should try it out. This is the graph I get. As I understand since the machine is CoreXY, adjusting one belt...
Solution:
That means the upper belt needs a bit more tension.
Perhaps, release just a touch the lower and tighten the upper....

Orbiter 2.0 Current
Hi,
Just something I have seen while using the wizard. I selected "Orbiter 2" initially and had lots of extruder motor step skips. Only to realize the current was set to 0.35 Amps.
Went back to wizzard and enabled "Advanced" and see that the "LDO-36STH17" was selected. Changed it to "LDO-36STH20" but see the current does not update to 0.85A...

Can not open RatOS in the browser
Im trying to install RatOS for my Vcore4. I use the raspberry PI imager and make sure I dont add any other settings.
I plug the card into the PI and the hotspot shows up and I connect the PI to the wifi. The hotspot disappears and I connect back to the wifi I connected the PI to.
RatOS appears in the router interface. When I try to open http://RatOS.local/config or look up the assigned IP-adress of the PI it wont open mainsail in the browser.
What am i doing wrong?...
Merc 1 Hydra RatOs 2.1
I have a odd issue and for the life of me i cannot figure it out, printer was working great but hated the toolhead so i swapped it out to a stealthburner with bambu hotend, did the calibrations for new toolhead beacon heightmap all that stuff, all worked fine, sliced a test cube sent to printer it does its things z tilt, etc but right before it does the adaptive mesh it moves to front left corner and slams into the front profile, then it slowly does a moonwalk to the right likes its doing a purge line but it does nothing, then it moves to right corner then does the scan and back to right corner and does the blob, and prints perfect, i cannot get it to stop slamming into the front rail. i did no changes other than toolhead , i have sized down the bed mesh a lot still does it. has the frabreeko 400mm bed, using orca slicer and copy n paste gcode from ratos set up, nothing added to it

Chamber heater settings question
I’ve added a DIY chamber heater based on a bath heater.

- a sensor in front of the heater (sensor pin PF5);
- a 12V fan connected to PE5;
- a 40A SSR connected to PA2 and to the heater....

Extra’s.resonance_tester ERROR
I have updated everything and installed ratOS multiple times, but I still get this error. It’s really frustrating because I’ve been struggling with this for months. Can you please help me solve this?

ratos-configurator: invalid
I ran into an issue, I can't recall exactly what it was, but when searching here there was an explaination that a bug slipped through and to update to the latest. I went into
Machine and clicked UPDATE ALL COMPONENTS, this seemed to complete, but then I'm left with ratos-configurator invalid. I did some searching and found some information about ratos doctor, I tried running it and got command not found, I searched that and came to this post: https://discord.com/channels/582187371529764864/1329115674215448616/1336836562381570149
I tried those instructions, mainly switching to v2.1.x-deployment branch, however even after that I still get:
```

-bash: ratos: command not found...Solution:
I reimagined the sd card a little bit ago and am currently installing things in the prescribed order.
