Lurch,
below is a picture of the PID temperature controller I recently finished.
Are you telling me that you keep your casting pot half full (or a little over half)...and when the "
self optimaization" is done, you fill it up normally? Or are you telling me you ALWAYS keep your casting pot half full?
By the way, I am using a Lee Pro 4-20. Shoulld I keep the knob turned all the way up to the HI position, or should it be kept lower? What are your observations?
Jeff423,
I will try what you said above.
QUOTE: One thing you might try for the self tune is to let it get to the correct temperature, then turn off the controller. Restart it and go back through the auto-tune. This will reset the PID for casting conditions - as opposed to bringing it from cold all the way to casting temp.
I am using a 25 amp SSR, with a large aluminum heat sink cannibalized from an old mother board. I believe it should do the trick.
Thanks, and if someone has something else to add...add right on!
In Christ: Raymond
PS: I'll be doing a tutorial soon...so stay tuned.
