tatel, what version are you using?
Seems like an older version since the set temperature is not present!
Also what's with the number format?
100 20 2,50 1 0
P I D, ? ? ?
Yeah, it's FW 2021-08-02a.
Format: Kp Ki Kd Imax Imin --- ADC values
Station is a Quicko. Tips are the cheapest Quicko, too.
I don't know what Imin is for, I see it takes negative values only. Did nothing with it.
Imax: going to 1 from 0,5 helps with the sponge test. Also it puts some 3-4ºC more on my tips. I would say temperature drop at Imax=1 is half the drop than at 0,5. Sponge is gravity dripping wet. By putting the tip in just one place in the sponge, temperature never drops more than some 10º. If I do it wander along the sponge, then in some 10-15s temperature drops 20º or more. A guy can see the power bar going to 100% first, then the big temperature drop happens.
With the fat tips I can set Imax 1,5 without noticing any weird behaviour. D52 with Imax=1,5 seems to be a monster, see video below: coin test, 100 mm Sn60Pb38Cu2 solder, 357ºC, Imax=1,5. Yet I'm sticking to Imax=1, just in case any tip would go red hot. It seems to be good enough for usual cases.
Kp: 60 seems to be a good initial value here. Fat tips usually allow to go further, I did tried 150 in some cases without noticing any problems. Again, I'm sticking to a more conservative Kp=120 max
Ki: it's effects are the more obscure to me, but generally speaking, I didn't noticed any oscillation increase with it in the 20-40 range. Most of my tips seem to like it at 20; but some wants it at 40
Kd: wildest setting, going further than 10 gets me increased oscillation with any tip. Most of the tips want it lower than 5, some really want it at 0,5.
Well, that's all I have to report. I could try some newer version in the future, should there be good reports about it. So far, I'm pretty happy with it. Difference with set point never goes further than 3ºC after stabilization. That's pretty darn good for me. Time to do what I bought this station for.
Thank you all.
