Cleaning nozzle after filament run-out
I'm looking for suggestions on how to clean out the nozzle of a Rapido UHF (0.6 mm nozzle installed) where I ran out of filament (PETG) and there's some cold filament stuck in the heat break (apparently) between the LGX lite and the Rapido. I haven't had any luck pushing it down or melting it out or cleaning it with needles. I'm hoping to avoid taking it apart, but that's going to be my next step barring any better ideas.
Fuse
Hi
It seems like something is wrong with my printer. As soon as i try to heat up the bed or hotend the fuse breaks. I don’t know why because it used to run just fine.
thanks for any help...

Idle 4028 part cooling fan
Hello! I'm back with another question on my setup (now that I have a brand-new-and-working ebb42 :D)
I'm using a 4028 fan for part cooling.
Problem is: 4028 fan is not starting with M106 255 gcode command. It moves a mm but that's it. And no reading on the tachymeter either....

Probe issue with BIQU Microprobe
So yeah, I'm having serious issues. At first I was getting random drops of the tip. I'd start a print just to find that the tip of the probe didn't retract and was pulling the first layer off the bed. Then at times, it would deploy mid print and the tip was hitting the part. We found that the probe wasn't always retracting, as if there wasn't enough power. The tech figured out that the problem was probably inductance. I took all the cabling out and placed it back in the harness in a careful mann...
Layer shifting
Hello guys, I'm getting a layer shifting issue. I got that with stock belts ( they were not straight in some places) , then I cut them a bit where they were curved, it became better, but still, if i was increasing speed layer shifting occurred. Now I've replaced belts with expensive gates one. Printer become quieter but still if im trying to print at higher speed - i'm getting issues, you can see in the attached photos. So maybe some one have ideas on this topic ?

Bondtech LGX extruder binding
I have two LGX extruders. One is on my VCore 3.0 500 that has worked great with no issues even when the enclosure gets a little toasty (~70c).
However, I have another extruder that is brand new that I was upgrading my Pruda Bear with. Just finished FINALLY getting around to the Prusa 2.5'ish to Prusa Bear upgrade and moved to a HeroMe Gen 7 carriage and Revo hotend. Got everything going and was pushing plastic getting ready for test prints.
I noticed that the printer would stop extruding after a short amount of time. Chased several normal problem solutions (bump up temp, bump up current, slow things down) and nothing seemed to work. Took the extruder apart and lubricated everything. By hand it seemed to function just fine. Put it back in the system and back to not extruding again. Took it apart again and put it back together. Started testing movement by hand again and I noticed that there is a point where the gears seem to bind. Fairly repeatable at the same spot. Seems more related to the large gear rather than the stepper spur gear....
Octopus 1.1 - connection problem
Hello. I have a problem with Octopus 1.1. The board is new. I am unable to connect it to either an RPi or a computer (Windows doesn't detect it in any way). After powering it on, 3 LEDs light up. Uploading firmware works (it changes from BIN to CUR). I also tried connecting it via UART.
Is there anything else I can try to do, or is it likely to have a factory defect?...

EBB36 disconnecting every restart
I’m having an issue where my EBB36 doesn’t initialize or show in USB via lsusb or ls /dev/serial/by-I’d/* if I start up the system or if I do a firmware restart or basically anything that requires Klipper to reinitialize. However, most times, if I switch the USB cable to a different port on my Pi 4 B, it will immediately detect it and finishes booting Klipper and works fine.
I have no idea what’s going on with this. Any ideas?...
After recent maintenance and upgrade, I am getting "move out of range" errors
Hi all.
Recently upgraded to a Bondtech LGX and BambuLabs 0.6mm hot end. We took the opportunity and also replaced the BL Touch for a BIQU microprobe. The probe now sits a bit further away from the nozzle than the BL would.I assume this may have something to do with this error that now pops up whenever the printer is creating a bed mesh without using the built in "PAM" method.
What do I need to change in the printer.cfg file to compensate?...

Part cooling fan always on
I got to powering up my ratrig and I noticed my 4028 Nidec fan spins up immediately and doesn't turn off. I followed the build guide and connected the pos/neg wires to the always on fan port of my motherboard (octopus 1.1), and the pwm (blue) wire to the bottom fan port as instructed. I also have a fourth wire coming out of the fan (yellow iirc) but didn't use it as nothing is mentionedcabout it. What could be my issue?
Poor bed adhesion
Hi everyone! I’m having an issue with getting my ASA prints to stick to the bed with my v-core 3.1 (no enclosure). I’m using the included magnetic build plate and i have tried adding hairspray to no luck. I have cleaned the bed with isopropyl yet my prints doesn’t want to stick to it. I get 10-15 layers in and it pops off. The photo is for reference as how the parts I’m trying to print look, to me there should be a good enough surface area for the print to stick.
I’m using the 3DO black ASA sourced from ratrig, the hotend is printing at 250c and the bed is at 105c. Any tips?...

v-core 3 suddenly stopped working
I have a ratrig vcore 3.1 200 that just suddenly stopped working. When I turn it on, it starts up as normal, but I can't log on to the interface at all. I've tried to hard restart it, but that doesn't work. Is there an easy fix, or will I have to reinstall klipper? Has my pi killed itself? What's going on?

IS not working or what's causing the ringing?
I've been at this for days now and just can't figure it out. What ever I do I just can't get rid of the ringing.
These four parts are printed with exactly the same settings beside external perimeter speed which is 80, 180, 190 & 200mm/sec.
I was trying lower speeds when someone said the steppers worked best in the 180-200 range, hence the big gap in speed.
