If I load fialment and it extrud fine, Start a print , it homes, then z tilt, then bed level. When it start to extrude the blop sometime it is okay but then fail in the print, but most of the time the extruder just skipping at the blop. I did try a new heatbrake with no luck also did change the 40x40x10 fan to 40x40x20 fan but it is still the same problem. Any ideas there c...
Unpredictable layer shift on brand New Vcore
Hi ! This freshly built vcore 300 is displaying some weird, inconsistent layer shift all the way through the print.
I checked the Z coupler and X/Y pulley, tensioned the belt.
The printer moves fine, feel fine, extrude fine and the part is solid but its useless. ...

Delta Fan not turning off at 0%.
I have installed a delta fan today, and the fan will not shut off when its indicating 0% in the dashboard. I have everything connected to the octopus 1.1 pro board like in the screenshot attached. I also included the following to printer.cfg:

pin: !fan_part_cooling_pin

Octo board not behaving correctly
I'm trying to set up a VCore 3 but I was having a belt issue which I got fixed, but now the Octo board is doing weird things. Its showing 4 new green lights that I haven't seen before, is outputting power to the hotend when I plug it into the power outlet, isn't powering the raspberry pi, and crashes RatOS when the raspberry pi is independently powered with a 500 internal server error. I thought reflashing the board might fix it but I'm having trouble with that as well. Should I get a new board,...

New Build V-Core300 Y homing goes toward the front with endstop switches
When I am attempting to home Y or Home all, Y is travelling toward the front of the printer away from the endstop. X homes as expected.
I have been searching for a cause/fix but I haven't had any luck.

Problem Homing X and Y
Hey guys I'm trying to set up a V-Core 3 and having trouble homing X and Y.
When I initialize homing on x it sound jammed and then says - "No trigger on x after full movement"
If I then do y it gives the same error.
Any ideas on what is going wrong? I can't figure out if its a wiring/control issue or a build/mechanical problem.
Happy to send any videos for more info....
FIXed: Section 'ratos_homing' is not a valid config section
So today I started my VC 3.1 300 and had several Repo is corrupt errors in the machine section, RatOS, Klipper, Moonraker and RatOS Theme were affected.
A hard reset on those repos seemed to fix it, however after rebooting the pi I get the error:
Section 'ratos_homing' is not a valid config sectionWell I just found the fix and thought I'll still post for future reference:...

Weird error messages
I keep getting this error message. Can someone help? I think these messages pop up thousands of times during a print. See photo for error.

Cracked heater or...
Hi, so I recently made a print, had a little clogged of filament. Either the temp for material was high or I did jot force the nozzle enough.
Cleaned everything up. Heated the heater, changed the nozzle to a new one, made sure everything was clean, tightened up.
Cooled down, added the sock....
Solution:
It's either the thermistor not reading to, or the heater not heating up. Either way I don't know if those are replaceable on the rapidos. Worth looking up

Dual Axis Z1 moves in same direction for all moves
I have a configuration for a dual Z axis using a SKR 3 EZ. When i try the
STEPPER_BUZZ STEPPER=stepper_z1
command, or try homing, the motor moves upwards even when it should be moving downwards. It also moves upwards when it should be moving upwards.
At first I thought it was wiring, but since i confirmed proper movement on the other Z motor, I swapped the cable completely, and it still does it on Z1 motor. I also plugged Z1 motor cable into Z motor, and when I do it only moves in one direction.
```...adxl345 crashing the MCU
I have been trying to follow the RATOS wiring for the octopus max ez to wire in a adxl345. The printer works fine without the adxl but the MCU will not boot with it attached. what do i need to do the wire the ADXL into the RPi ? I have run into issue with trying to get the SPI bus to work for other things so if i can avoid it that works better
Solution:
https://www.klipper3d.org/Measuring_Resonances.html
If you want to use the pi you should be able to follow the usual klipper guide for wiring and then add in your user overrides section
```
[include RatOS/boards/rpi/config.cfg]

Want to change X&Y from motor outputs 1&2 to 4&5
I suspect that motor outputs 1&2 on my Manta M8P 1.1 are bad, I'd like to change the output to 4&5. I copied [stepper_x] example from the BTT Github and changed the pins to the appropriate ones, but I keep getting an error. Is there something in the base config that need to be commented out? I don't know if I'm doing it correctly so I'm unsure if it's hardware or firmware at this point.

'Crunchy' Y-Axis Rails - V3.1 300
Hello fellow riggers!
My Y-Axis rails are sounding very crunchy, do you have a recommendation on the best way to clean them and what lubrication/grease should be used?
I've spent a good few hours on reddit posts and YouTube videos about this subject but everyone seems to counter each others points and it's driving me a little crazy so i figured best to ask the guys that know.. ...
Hotend Heater going too high?
Not sure if anything is going wrong, have rapido 1.0 hotend with 104 thermistor. I was printing PLA and was going to go back to ABS, but I noticed it was crackling and smoking a lot. I checked the temperature with a camera and it was almost 300 C when it was set to 250 C and was reading as 250 C. Seems odd as it is working at 220 C correctly.

Need help configuring fan.
I have 3 40mm noctua fans I would like to wire 1 on the raspberri pi and 2 over the stepper drivers on the control board. They are 3 wire fans but I can switch them to two wire if needed. I have attached the printer.cfg file. Thank you guys again!!!!!
Trouble with printer.cfg after IS calibration
