very good. all three of my stations are like 30-40C too low and I lost my manuals so this video will help me later this afternoon. I also ref'd your video in a reddit post
Nice demo, but for most people with 858d, they can just do much simpler and faster calibration using a digital oven thermometer and adjusting calibration potentiometer in the front with screw driver. It takes just few minutes to calibrate.
Cheers bud, that was much more easy and accurate throughout the entire range. I didn't realise that CAL hole was a pot, I thought it was a tactile switch for programming.
I think that there is no fixed temperature for reworking but depends from factors as pcb design and the size of the component.The key is to maintain a constant temperature and not the accuracy of the readings since these are very relative.
You are right. Today I was desoldering a tqfp 144. It just wouldn't come off. It came off after I liftet the board up from the aluminium bed it was resting on..
Hi Wouter. Yes. I forked the github repository for this FW, added the calibration menu and adc->temperature conversion function using piecewise linear interpolation (easier than it sounds) (just using arduino's map function more than once :) ). See my previous video for coding. :) th-cam.com/video/FgPHER2A-pM/w-d-xo.html

Nice, now it reaches the T-10 degrees slowly and the final T even slower. It behaves pretty much like my 858D+ v3.0.
My 858 stopped getting hot. And it's rebranded to Yihua, and there's no calibration for it 🤔

@@robotmad💀I thought it was an led this entire time.
but is the digital oven thermo even calibrated?

wow thanks its realy great idea i thought its faulty but this procedure was hidden thank to expose it
What is the little CAL button above the two red buttons for? Is it an indicator or some kind of micro switch?
To call the stored temperature in memory.
somebody in the comment section said that is a potentio, you could adjust it with a screwdriver.
The PID control (specifically the proportional and derivative part ) is not set correctly if the response time is poor.
How about an USB connector bridge for flashing the arduino?
Did you figure the procedure out yourself Hans?

Oh wait I saw that video.
your instructions are not clear and i cant understand you. too bad,
Ah. Sorry man. For what it is worth it is not worth calibrating this product.
Poor explanation, could you improve this video doing another one
It was really hard to do this project, and I don't want to do it again.
Terrible hard job...
