MCU 'mcu' shutdown

I haven't Printed in Months did not change anything and now every time i try to start a Print it says "MCU 'mcu' shutdown: Timer too close This often indicates the host computer is overloaded. Check for other processes consuming excessive CPU time, high swap usage, disk errors, overheating, unstable voltage, or similar system problems on the host computer....

Defective heat pad

I believe I have a defective heat pad. I tested resistance which was 0. Is there anything else I should test before ordering a replacement? Any experience on whether they would provide a replacement? I took delivery of the printer in December.

How to enable nozzle wipe

I have the two felt nozzle wipe pads on the left and right arm of my machine but they are not being used. I did some searching in the discord and found a few threads and copied "variable_has_front_arm_nozzle_wiper: True" to my "[gcode_macro RatOS]" section. They are still not being used. I do not see any other threads with solutions to this. Could someone please let me know what else I need to enable? Thank you.

Large nozzle extrusion issue

Trying to use a 1.8mm nozzle. Adjusted all the settings I thought I would need, getting this message when the print starts. Can anyone advise what to change to resolve this? Thank you.

Solution:

Anything you add into the printer.cfg will override existing values. So if they’re not in there already then you just need to add them with the desired values.

Another mysterious "Lost communication with MCU 'mcu' and 'mmu' and 'EBB'"

Hello all, I'm running VC3.1 on RPi4B+, Octopus PRO, Fysetc ERB V1 (ERCF), EBB36 and 1080p usb webcam. All "big" things (servos, RPi etc) are powered off dedicated 24V-5V stepdown.
Recently I added EBB36, fixed problems with shutdowns due to EBB overheating and all was looking great. But I started getting "Lost communication with MCU '....'" error - all three MCUs lose communications at random. Webcam shutdown with "NO SIGNAL" on screen as well. Things I've done:...

Not able to re-flash my Octopus V1.1 via any RatOS method

I've had consistent errors with RatOS and was advised to reflash everything. After re-flashing the pi, the version of the Octopus wasn't aligned but now I'm stuck in a "DFU not found" state while trying to flash the octopus. When it did happen to detect (not anymore), I remove the boot pin jumper, flash and get taken back to the same prior screen which tells me the versions aren't aligned after a few moments of "Flashing...". Has anyone else experienced this?

Vcore - 4 500 - IDEX the pause starts itself

Hi, I created the settings according to ratrig wifi, I didn't change anything anywhere and I have several problems. Sometimes a pause is executed independently, in the console there is no reason why the pause was triggered. When I put resume it goes, but again a piece of the perimeter is skipped. About twice it happened to me that when resuming after a pause it said the print was done, when it had about 10% of the print done. Once I turn off the filament sensors it is ok. Since I communicated wi...

unknown config object 'bed mesh'

VC4 is giving me this error upon booting. I have had it running and printing but start experiencing problems. I have reflashed my os and re did the configuration on hardware. I am now at this point and when trying to ssh into my pi it will refuse connection. Any help would be greatly appreciated, kinda stuck at this point. I came upon other threads with this but no solution was posted.

severe gantry twist and how to solve this...

Hey there... VC4 300 IDEX. I have a severe gantry twist. I had bad resonance screens and strange belt tention graphs as well. So I did a bit of research and found the Gantry twist (Core XY + hybrid) from the commissioning guide. To tell you in advance, I did purchase the printer used, so I did not built it myself......

How do I stop my printer waiting in the middle once the print starts?

From the video you can see it does its prime blob and then goes to start but sits there while the bed cools from from 61c to 60c but in that time it causes a bunch of oozing. Is there a way I can fix this?

Solution:

Found the issue. In SuperSlicer, I had to uncheck this. Its not needed since our start gcode handles it

Beacon lower than nozzle

Was having first layer issues when I realized my beacon is much lower than my nozzle. There is no way the nozzle will be close enough to the bed without the beacon scraping. Can someone help me understand what I did wrong?

Solution:

I had to redo my mesh after adding the UHF extender, that was the issue. Working now

VCore 500 Bed

Hey guys need some support. I finally got everything built and running well, but here is the issue. My bed looks like a soup bowl. There is a ripple in the back right corner that moves if I rotate the PEI Sheet, so I know the issue there. Weird thing is if I get z-offset low enough in the front, it is too close in the back. Bed Mesh compensation is running, I can see the z screws rotating. Is this a warped bed, or a bowed gantry? I have squared the frame and made sure all my linear rails are tig...

Beacon offset incorrect

Hey everyone, I have just done a fresh install of RC3 on my rebuild 3 hybrid The issue I am running into is thst when the beacon does z tilt, it seems to be using the offset of a blTouch or induction probe instead of the nozzle for the beacon probe. I have done the configuration and set it to beacon. Is there anything else I need to do to fix this?...

Solution:

---- Alright! Adding: ```cfg [z_tilt] points:...
