@synergy41 as a suggestion, please remove this line before sending config.g

M587 S"Livebox-2AF2" ...

Also a M122, please.

I am presuming that this all was working before and nothing has changed, apart from using RRF3.

My first idea was that the heaters needed tuning, but after looking at other posts, it could be a config or an issue with the thermistor.

Might be worth tuning the heaters while you wait for someone more knowledgeable to see this post.

Paul

Yes, everything works well before the update.

Thanks for the info.

Try tuning your heaters so your are using PID values instead of Bang-Bang.

M303 H0 S(Max temp you run with, ie 80)
then do the same with H1

This document is helpful

Let us know how you get on.

He doesn't want to go through the process?

Check wiring first.

Do you have the original config.g pre RRF3?

P.

@PaulHew
here is the old file.
config.g

PaulHew

Config looks fine.
Could be wiring or sensor could of gone faulty.

I guess you have a E3D hotend?
This is from my config

;HotEnd Configuration
M308 S1 P"e0temp" Y"thermistor" A"E3Dv6" T100000 B4725 R4700 C7.06e-8 H0 L0	;A"E3Dv6"
M950 H1 C"e0heat" T1				;
M143 H1 S280                                                   ; Max temp
M307 H1 A503.9 C237.3 D4.9 V24.2 B0        ; PID tuning

You might want to try moving the heater to a spare heater and try again, to see if the issue follows.

I still suspect wiring or thermistor.

Am hoping someone more knowledgeable might jump in!

@PaulHew
I think you were right, there must be a cable problem.
I have removed all the plastic collars from my cable management and now it is fine if not a slight temperature
variation of + - 2 °.

PaulHew

Brilliant, at least you know where the problem lies now.

thanks for letting us know.

I recommend tuning your heaters to achieve the best performance and not use Bang-Bang mode.

Paul

The huge drop shown in the temp graph indicates that the sensor has lost communication with the board entirely. Failing crimp or cable exacerbated by movement and flexing during a print as you've found.
