how the heating control operates

[luca Massimiliano]

good morning I have a RepRapFirmware for Duet 2 WiFi/Ethernet version 3.2.2 I'm trying to calibrate my 2 new CHC V6 Hotend Ceramic hotend at 24 60 w volt NTC100K B3950 here are the commands and responses:

first Hotend
************COMMAND **********
M303 H1 S275 (275 temperature because my wire requires max 270)
_ANSWER
Warning: heater behavior was not consistent during tuning
Auto tuning heater 1 completed after 4 idle and 25 tuning cycles in 413 seconds. This heater needs the following M307 command:
M307 H1 R4.649 C105.2 D1.62 S1.00 V23.8
Send M500 to save this command in config-override.g
************COMMAND **********
M307 H1 R4.649 C105.2 D1.62 S1.00 V23.8
_ANSWER
Warning: M307: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 514C

@luca-Massimiliano best update to 3.5.2 as the heater tuning has improved since then.

THANKS WHERE CAN I DOWNLOAD version 3.5.2 COULD IT BE THIS?https://configtool.reprapfirmware.org/

@luca-Massimiliano https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.2
And tune as a tool rather than a heater

M303 T0 S275

GOOD MORNING I HAVE A Duet 2 WiFi, AFTER THE UPDATE TO THE LATEST VERSION 3.5.2 ON THE DASHBORD, ONCE THE SET HEATER TEMPERATURE HAS BEEN REACHED, THE EXTRUSION CONTROL BAR CANNOT BE USED, INSTEAD THE DISPLAY IF USED GIVES THE FOLLOWING ERROR error: attempting to extrude with no tools selected. here is the config
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin bedtemp

@luca-Massimiliano you need a tool to be active.
Send Tx where X is the tool number that you want to drive

[luca Massimiliano]

@jay_s_uk
how should I put it in the config

[jay_s_uk]

@luca-Massimiliano you have two tools so it depends which one you want to be active when you first turn on the machine
Either add T1 to the end of the config or T2

[oliof]

@jay_s_uk rather T0 or T1?

[luca Massimiliano]

@jay_s_uk
I don't understand in which config .g command should I add t0 and t1? the problem is that the commands on the dashboard and on the duet display are not activated if I send the extrusion error: trying to extrude with no tools selected.

[oliof]

@luca-Massimiliano just add either T0 or T1 on the end of config.g

[jay_s_uk]

@oliof he has the tools setup as T1 and T2

@luca-Massimiliano said in how the heating control operates:

; Tools
M563 P1 S"LUCA1" D0 H1 F0 ; define tool 1
G10 P1 X12.8 Y3.9 Z0 ; set tool 1 axis offsets
G10 P1 R0 S0 ; set initial tool 1 active and standby temperatures to 0C
M563 P2 S"LUCA2" D1 H2 F0 ; define tools 2
G10 P2 X-12.8 Y3.9 Z0 ; set tool 2 axis offsets
G10 P2 R0 S0 ; set initial tool 2 active and standby temperatures to 0C

[oliof]

@jay_s_uk well ok then (-: That'll confuse the average slicer tho

[luca Massimiliano]

@jay_s_uk
I inserted t1 and t2 without anything else and it works, but I never did it in previous versions and it worked anyway, has it been changed in this version?

[luca Massimiliano]

@oliof
now I try to send a print with slicer,

[jay_s_uk]

@luca-Massimiliano you shouldn't insert both of them into the config, just one of them.
you can only have one active tool at a time.
and no changes i'm aware of in that area for ages

[luca Massimiliano]

@jay_s_uk Now I try again but with a declared tool if activated first the second one doesn't work

[luca Massimiliano]

@luca-Massimiliano
I had version 3.2.2 before and didn't declare the first extruder
