Hello all,

If using a temperature-sensing coil you can define the preheat. This makes sense and I understand it's purpose.
It is also very easy to understand the time limit...

However. if the preheat power is 100w what diference does the punch make? If it's soft does it hit 90w or if it's soft does it take a second to get to 100w?

Another question on the matter, if the preheat power is 100w and the power setting is set to 50w will it fire 100w for a second then 50w?

Could somebody explain the exact way it works for my understanding?

Thanks

Punch is how "aggressive" or close to you set temperature it will go and maybe how quick it will ramp up.

The PH will increase the power up to the PH power setting until the time limit is reached or the temperature reaches the threshold set in the Punch, whichevery happens first.  The default threshold was 100 F below your set temperature on the 40 and looks the same on the 200.

Thanks for the reply Vapingbad. This is how I imagine it to work and understood it to work.

However if setting the punch defines how close to the temperature it gets why do we set a power option aswell?

In my head... Power = temperature - raising one raises the other... So how can you set the power and have the punch change the heat temp? If possible I'd love to see two number examples (even if not completely mathematically accurate)

Power = heat, then that heat is applied to something and depending on many things like it mass and it's current temperature the temperature will rise.  EG 100 W for 1 s into a small single coil would get to a higher temp than in big dual coils.

So lets go with 100w 1s and preheat SOFT and preheat HARD on 400F?

If it throws 100w surely it'll always have the same punch?

Try them out in device monitor and see, you should see the pre-heat stopping quicker with the punch lower, but there are so many variables you may need to adjust power and temp to make the plot easier to read.

I found the following in the video tutorial (so to add the numbers to the excellent explaination of VapingBad): The Preheat punch setting runs from 0 = 160°F to 11 = 10°F under the set temperature.

EDIT: removed my wrong train of thought.

So with that logic... If the punch is on 11 (and 200w) it will ignore the power and go for the Temp-10 degrees... So I'm guessing the mod will just go with the lower of either when it goes to fire?

Yes/no, for the duration of the preheat time limit it will apply the preheat power but regulates this down if the temp minus 10 degrees is reached. After that it will regulate the power to keep the  temperature, with the power of the profile as maximum limit.

I had a go at a flowchart

E: corrected a <= to <

That diagram is very helpful actually. Hopefully just for future people Evolv will come along and say "Yeah VapingBad was correct again!" Thankyou for explaining it

Hey VB.. you spying on me through my web cam??

I was working on the exact same thing last week while trying to explain to a friend of mine how the DNA works.

I must admit yours is much better laid out than my first effort, great job mate [smile]

You may think that, I couldn't possibly comment [cool]

I have just spotted an error on the temp limiting section the decision "Temp too high or low?" should just be "Temp too high?" and the "low" path should be "No" and the "High" should be "Yes". I will change it and repost.
