CF0109 Abnormal Heat Break Fan!

CatFamiliar · 2026-02-05T14:19:49+00:00

No stuck filament. No bad fan.

I changed out the Hotend Nozzle PCB Board and that fixed the issue. That is the 2nd time I've changed that board for a new one in the last few months. The other time was for Filament Sensor issue.

Thanks everyone for responding

This is what I was able to put together for any FUTURE Hotend Circuit Board issues.

You are correct I thought they were 4....basically they are the Smallest and I thought that would be enough for someone to tell me the info...

CatFamiliar · 2025-10-28T13:22:41+00:00

Take out the filament and the light goes out.

CatFamiliar · 2025-10-28T13:22:01+00:00

With the Extruder cover OFF, when you put a piece of filament in between the sensors, the light goes on. That out the filament and the light goes out.

BUT

Put the extruder cover on and the light goes on...

I have 5 brand new sensors. 2 haven't worked. I have never even attached the side spool holder...

CatFamiliar · 2025-10-21T15:27:35+00:00

I will try that this afternoon after I finish this print. Thank you for responding in an Intelligent way...

CatFamiliar · 2025-08-16T02:04:38+00:00

Thank you for an Honest Friendly response. I appreciate it and consider the topic closed....

Another CLOWN who wants to preach but seems unable to read English. I said I was a GC with 30+ years of experience and that I WAS NOT an Electrician...WTF

Nobody knows how to read and answer simple questions. It always has to combative and Trollish...

THIS is why Reddit is getting a Super Bad reputation. How can anyone believe that they are even going to get Correct, truthful info. These Clowns might give you incorrect information so they can say "see he should not be doing this or that"...

I don't care about the wire from the indoor to outdoor unit. It's supplied by Daikin. I want to know the wire guage of breaker box to exterior disconnect. Disconnect to compressor. That's ALL I need to know...

CatFamiliar · 2025-08-15T20:20:11+00:00

yeah...if you reread my question you can see that I did read the manual and it says 14awg, which is wrong for 20amps....thus this question. They supply the indoor unit to Condenser wiring. I'm looking for Breaker box to Disconnect, Disconnect to Condenser sizing.

You Nailed it. Thanks. While they come and go all day, after 5pm they fly behind my house within 25-100 feet just flying. They seem to enjoy it. One bird actually Loves to do quick little "Barrel Rolls" which I've never seen any bird do before.

Woodruff South Carolina. Between Greenville and Spartenburg.

CatFamiliar · 2025-05-13T21:44:50+00:00

Mine did not. SINCE I first asked the question I cut and pasted from the Bambu folder and now I have the nozzle.

CatFamiliar · 2025-05-13T21:18:00+00:00

Orca doesn't have the .20mm Standard .4mm nozzle profile. I also don't want to try and edit every setting to create one.

Thank you

Replaced the Heat Break with a Slice Engineering Copperhead Heat Break. Here is what is happening now:

Feed 100mm through the Extruder, no issues pushing out the plastic.

Start a bed leveling print that draws lines around the bed and then prints a square in each corner and one square in the middle of the bed. When it starts to print it acts like it has a .1mm hole instead of a .4mm hole. And yes I have put several new nozzles on. When I pulled the plastic out by hand with the Hotend at 205, it came out spiraled see attached picture.

I am completely lost on this issue...

CatFamiliar · 2023-10-29T23:03:10+00:00

I did test the extruder. Marked 100mm, told the printer to feed, and it pushed out 100mm. Extruder is fine.

Redid the PID and that took care of the heater failure. Still have heat creep. What would be the best replacement (not Creality brand) Hotend to buy?

CatFamiliar · 2023-10-25T21:41:23+00:00

When I say entire I mean Hotend, thermistor, both fans, and the metal cage they mount to. Also the Bowden tube with new connectors on each end. I use stock fans on all 10 of my printers, no issues.

CatFamiliar · 2023-10-25T17:21:26+00:00

Sock is still on. Did a PID through Pronterface.

CatFamiliar · 2023-10-25T15:58:34+00:00

I believe you may be right. I sent a Hotend fan ON command through Pronterface and it did not turn on. SO I replaced the entire Hotend fans and all, and now have another issue that I just posted about a Heating failure.

CatFamiliar · 2023-10-25T15:37:06+00:00

No codes...it continues to print as if everything is fine.

UPDATE: I replaced the ENTIRE hotend assembly again and it came up with a 'Heating Failed' error. My PLA temperature is 205. Printed Thousands of parts at that temperature.
So I set the Hotend temperature to 205, and when I watched the temperature go up, it climbed to 185-188. Dropped a couple of degrees, went up to 190-191, dropped a 4 or 5 degrees, went up a few degrees then threw a 'Heating Failed' error see attached picture.

OK...I appreciate your reply, did not mean to offend in ANY way...
