@speed0verdose what size heater cartridge is it? theres a good chance it can't reach 300 degrees
also, you should tune your hotend as a tool using M303 T0 S260 obviously adjusting the temp to whatever you want. This activates the part cooling fans through the second half of tuning to take their effect into account

Sorry, i forgot that important part.

I'm using a Slice Eng. 50W cartridge at 24 volts off the card and a 2-wire PT100.

I hadn't thought of that. How would that differ from using H1 to T0?

I have set up more than 1 "Tool" for different nozzles that require different Z offsets. Will that need to be taken into consideration?

@speed0verdose here's what the wiki says about tuning as a tool.
It also allows for tuning a tool, rather than just a heater, which tunes the heater with related fans both off and on. The purpose of this is to allow the heater control to implement feedforward, which monitors fan PWM changes and adjusts the heater power, before the PID algorithm recognises that something has changed
Once you've tuned one tool you can just apply the same M307 settings to each tool.
You should be able to reach 300 degrees ok with a 50w cartridge

I'm still really new to this, but the only difference in my "tools" are the z-offsets and diameter due to different brands and style nozzles.

How do I enter different M307 settings for different tools, when it's the same print head, cartridge, etc?

What would those config sections look like?

I just ran the M303 T1 S300, and it failed again. Unable to reach temp. I know it's putting out 24V to the nozzle heater, I'll check the resistance in the cartridge and see what the amp draw is.

Is there something wrong with the assembly of the hotend sapping away heat? It seems strange that a 50w heater can't reach 300c.

I have to ask that now because it wasn't mentioned.
The PT100 thermistor for the HotEnd is connected to a PT100 daughter board, right?

Ich muss das jetzt mal fragen, weil es nicht erwähnt wurde.
Der PT100 Thermistor für das HotEnd ist an einer PT100 Tochterplatine angeschlossen, oder ?

I don't believe so, I'm using a HeroMe6 printed in PETG, using a Phaetus Dragon HF direct mount to the base with a standard ender heatsink cooling fan, and a Bondtech LGX Lite on top. I even used the thermal paste that came with the hot end on both the cartridge and sensor.

Just confirmed that the heater is pulling 51W from the wall.

yes, it's a 2 wire PT100 connected to a daughter-board see original post for how it's configurated.

I have a 60W heater and a PT100 thermistor on a daughter board.
I reach the 500°C specified by the Dyze-Design without any problems.
But I can remember that I once had the same problem and the temperature was not reached during PID tuning.
But that was sooo long ago that I no longer know what the error was.
I've been trying to remember it for hours, but no chance so far.
This drives me crazy !
It must be because of age !?

The question about the daughter board... we don't know each other here in the forum, so it could have been that you crimped the thermistor and put it on the daughter board pins on the Duet board itself.
I just wanted to rule that out.
You never know.

What I can think of at the moment... check the cables and also the connections such as plugs and screw connectors.
I would unplug the connector and plug it back in or plug it back together.

Do you have the original heating cable or did you install another cable as an extension?
Some cable types can cause problems and are therefore unsuitable.

With PID tuning, the parameter P is set to 1 by default, but you can still add the parameter P1 to force the 1, i.e. full heating power.
So... Enter M303 H1 P1 S260, or whatever temperature you want to tune.

My PID tuning was also done at 260°C, since I mainly print ABS and Nylon, that's the temperature range I use the most.

At room temperature, does the DWC read roughly the same temperature for all printer parts ?

Ich habe eine 60W Heizung und ein PT100 Thermistor an einem Tochterboard.
Ich erreiche ohne Probleme die 500°C die Dyze-Design angegeben hat.
Ich kann mich aber daran erinnern das ich einmal das gleiche Problem hatte und die Temperatur beim PID Tuning nicht erreicht wurde.
Das ist aber schon sooo lange her, das ich heute nicht mehr weiß was der Fehler war.
Ich versuche schon seit Stunden mich daran zu erinnern, aber bis jetzt keine Chance.
Das macht mich verrückt !
Es muss am Alter liegen !?

Die Frage wegen dem Tochterboard... man kennt sich hier im Forum ja nicht, von daher hätte es ja sein können das Du den Thermistor gecrimpt hast und ihn auf die Tochterboard-Pins auf dem Duet Board selber, gesteckt hast.
Das wollte ich nur ausschließen.
Man weiß ja nie.

Was mir momentan noch einfällt... kontrolliere die Kabel und auch die Verbindungen wie Stecker und Schraubverbinder.
Stecker würde ich einmal abziehen und wieder drauf stecken bzw wieder zusammen stecken.

Hast Du original Heizungskabel oder hast Du dort ein anderes Kabel als Verlängerung eingebaut ?
Manche Kabeltypen können Probleme verursachen und sind daher ungeeignet.

Beim PID Tuning ist der Parameter P zwar standardmäßig auf 1 gestellt, aber dennoch kannst Du den Parameter P1 hinzufügen um die 1, also volle Heizleistung, zu erzwingen.
Demnach... M303 H1 P1 S260 eingeben, oder je nachdem welche Temperatur Du tunen willst.

Mein PID Tuning ist auch mit 260°C gemacht worden, da ich hauptsächlich ABS und Nylon drucke, ist das der Temperaturbereich den ich am meisten nutze.

Zeigt das DWC bei Raumtemperatur aller Druckerteile in etwa die gleiche Temperatur an ?
