After a Pause & Resume MCU 'mcu' shutdown: Rescheduled timer in the past
During a print, I have pressed pause (on my klipperscreen), did some maintainance on the printed part (removed a blob of filament) and pressed resume (on my klipper screen). the toolhead starts to move to the proper location, however in the middle of the move, I get a MCU shutdown error.
Specs:
Ratrig V-Core 3.1-300 running RatOS 2.1 (latest update as per update manager)
Manta M8P (rev1) with a CM4 (with emmc)
EBB42 rev 1.2
Rapido Plus UHF CFT
Orbiter 2.0 with orbiter sensor
Beacon RevH
logfiles and cfg files attached
As I experienced this prior to upgrading to RatOS 2.1, I do not believe this is the problem (back then I believe it happend multiple times when pressing resume after a filament runout). Any help would be appreciated as now the pause/resume become unreliable...

Orbiter Sensor / Ratos MCU error after loading filament and Resume
I have a orbiter 2 with filament sensor, configured as per attached printer.cfg on a EBB36. This used to operate with the OrbiterSensor.cfg but this is very complex so I changed it acc. to Helge's suggestion in another post (adopting the Pins to the setup with EBB36).
One change that I had to make between the 2 configs is that I had to inverse the functions (remove the exclamation marks) and added the ^ sign as per suggestion of Helge.
- Pressing the unload butten works
- Sensor activates the Park & unload sequence during a print.
2 issues remain however
- Minor issue: When I pull out the last filament-bit out of the extruder, the extruder immediately starts the Load Filament routine. I quickly put the new filament in and it then continues loading and purging and waits for me to press the resume button.
- Bigger issue: after pressing resume, it briefly moves the extruder towards the resume point, the halts and throws an error:

This generally occurs when the micro-controller has been

Once the underlying issue is corrected, use the

config, and restart the host software.

PITFT50 boots into terminal login screen
Hi, I have been running klipperscreen on an old android tablet. Although it works it is not ideal and I have just bought, recieved and connected a pitft50 via the ribbon cable to the Manta M8P board. After some searching here on the forum (and putting in some wget's and blobs in) I have it now showing the Raspberrypi's terminal screen and it halts at the login prompt, wanting me to log in,.... any ideas how I could get it to go to the Klipperscreen?

Internal Error on "G4"
Looking for some assistance on below. I have an Orbiter 2.0 (on a RR3.1-300) with the orbiter filament runout sensor. I have installed, and are running the macro's that go allong with that. It has been working flawlessly for months but now, Since a couple of weeks I get an error.
When I run out of filament, the toolhead is parked in the back and any remaining filament is pushed out the back/up as normal and than it awaits the user (me) to add filament. When the filament is grabbed by the Orbiter, I get an error on screen stating: "Internal Error on command: "G4" "
I then need to do a firmware restart but lost the print. The part of the klippy.log (attached) also shows me another error: FILAMENT_LOAD
Not sure what is going on. I did not alter any of the Macro's. Any help would be appreciated.

Klipper errors after 2nd M600
I am attempting to print a small part with 2 filament/color changes. The part prints the first layer fine. I then have a color change (M600). also works fine. The next two layers are printed (also fine). Then upon M660 the filament change is executed like normal but when I then press Resume, the printer errors. (whereby at the first Resume at the first filament change, I also have pressed Resume and it doesn;t error...))

Start printing when (extruder) temperature is reached
I have seen a post a while back about this (I think) but for the life of me I can't find it anymore.
What I want to achieve is that the printer starts printing if the extruder temperature is reached. (for the first time)
My extruder temp alway overshoots a couple of degrees (dispite PID tuning) when heating up. Then it needs to come down a couple of degreed and only starts printing when it (slowly) reaches target temp (approaching from the top, so to say). I would like to have it start printing (or prime-blobbing) when it first reaches the target temp... I don't mind the overshoot in the Prime-blobbing phase...
anybody any ideas on how to achieve this?

Adaptive Mesh # probe points
Hi,I just made my first prints with adaptive printing on (VCore3.1-300, had 7x7 mesh points defined). Now for a print of 85x136mm it probes 3x3. Can I influence these nr of probe points and if so, where can I do that?
Also, What logics is used? Does it use the resolution of the 7x7?

Missing ref to Orbiter-2?
in the RATOS/extruders folder, I see config files for Orbiter and Orbiter-1004 AND Orbiter-2 (I own a Orbiter-2)
in Printer.cfg I do not see a ref to Orbiter-2.
-Do I add this ref myself? "[include RatOS/extruders/orbiter-2.cfg] "
-if so, how does the mechanism work with ref to /config/RatOS/steppers/ldo/36sth20-1004ahg? This folder contains 2 config files; one with 0.7amp and the other with 0.85 amp motor current. The Orbiter manual states I should/could run it at 0.85Amp but not sure If I should override this in printer.cfg

Resonance coming from rattleling bearing balls in X-carriage
Not so much a question but more a heads up for others that might be in this rabbit hole....
I am chasing noise in my EVA3 printhead for a while now. I expected a missed nut somewhere in the head and disassembled the head, reassembled and still hear this rattle in the head. I decided to re-print the main parts again and when assembled without the mgn12 carriage, there is no rattle. There is a rattling noise in the carriage however, due to the space between the balls in the carriage. I can mitigate this by adding grease, but this also significantly increases friction.
I also assume that my resonance "issues" (I still see some weird spikes in the graphs, so I just don't make the graphs anymore,... prints look super nice, though) are due to the spacing between the balls...
(and Yes, I tried stuffing in another ball, but that is just to tight and doesn't work)

Change Speed and Nr of Z-probes
High all, I was wondering if I can change the number of Z-probes (during tilt-adjust for instance) and the speed the bed moves during probing... In Marlin it was configurable but I have not found it in klipper yet. (running V-core 3.1-300 with MantaM8P+ CM4)
