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.

@phaedrux said in Target temperature was not reached:

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 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.

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 ?

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

@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?

@jay_s_uk said in Target temperature was not reached:

@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

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?

@jay_s_uk

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'm having trouble running a calibration Temperature Tower for PETG. I'm using a Post-processing > Modify G Code script that changes the temp every n layers.

However, when going up (hotter) in temp I am getting a fault that the temp is rising too slowly. I figured it must be because when I did the auto-tuning of the heater it was I only set it for 260C M303 H1 S260. I then tried to bump up the temp for Auto-tuning and set it to S300.

Slice Engineering 50W heater Cartridge
PT100 2-wire

However, this was when I started getting the error:
9/6/2022, 11:05:42 AM Auto tune cancelled because target temperature was not reached
9/6/2022, 10:58:42 AM Auto tune starting phase 1, heating up
9/6/2022, 10:58:37 AM M303 T1 S300 Auto tuning heater 1 using target temperature 300.0°C and PWM 1.00 - do not leave printer unattended

NOTE: M307 H1 has the original tune commented out so I could run the tune both ways, and both were unsuccessful
