(@Minkok, this means we do not need to continue prototyping the sensor board anymore, but thanks for your efforts nonetheless :-))You are welcome, but hardware filtering have to be done. The software filtering will be extra and give us posibility to extend the cables.
Anyway my choice is option2 ( simpler and will works the same way as changed ) and if it is possible can you test it?
Does anyone know the range of voltages that the thermocouple of the JBC C245 produces? Thanks!Look at your link - 2.35min,
If it is from contact sensing add 200k in serial to the input and make better 3.3v filtering at the sensor board.You can try to add in serial also Schottky diode (DinikS solution) extra to 200k resistor, to the input, if don't have upgraded version of the board, partially to decrease sensitivity for that behavior.
Hello folks, someone has come across something like this when you connect a transformer with two windings of 24 in parallel to the solder, then we get an interesting picture when we see that the heating starts normally and it immediately goes into hibernation and it seems that the soldering iron remained on the stand although it was removed from there and when connected to one winding, everything works like a clockIf it is from contact sensing add 200k in serial to the input and make better 3.3v filtering at the sensor board.
the issue with 210 soldering iron reshon by moving the department describing the part of exactly 210 soldering iron to iron.c a few positions higher, that is, all the soldering irons are indicated there in turn and I just changed their sequence and like a miracle 210 would come to life but ..... stopped working 245 and tweezers 120, who may have come across this or have some thoughts on this matter, I will be happy to discuss it, and this is 1000 percent software problem because everything has already been recheckedMy issue was hardware one, at least you can try re soldering Q2 driving circuit also.
I'll order the parts and test, it would be great if you could update the board :-)It is ready. I pm to you the link. If someone do not need noise protection part of the board, he needs to populate only 1 resistor and the fet tr. by channel - all the rest is the same. V1.2 differs from the old one only by rotated J3 connector (180 deg.), but it is marked properly.
That is great news! So I gather this is an updated version of the touch sensing board?Yep, you can. Note, it is not checked yet, but if you want, I can design a board for you to check it exactly where it is needed.
After that I can publish the design. Just tell me.
Also, if you wish, you can try it first on the fly, without creating a new board.
Hmm, still some weird behaviour, which might indicate a problem: When I touch the plates with my hand, the sensor acts as if the hand piece is in the holder.I think, now that is fixed for frequencies over 50 Hz at the input. Look here:
Need to be sure that Vadc is in correct range to find out what is wrong, Vadc or controller readings.
Thanks! I'm still tweaking some things but the core is for the most part done.Just start using it and you will soon realize why you don't need more powerful one. Current is a software limited to 5A. If you need more power use bigger tips.
Does anyone know if we can bump up the max power for the T245? I know it's currently configured to 130 Watts but was wondering if there was any reason from bumping it up to 150 or 160. I currently have a 160 VA transformer.
I have also attached additional photos to the prusaprints link with the top and side panel off.Now I have better look at it, it is really a nice case.
whether there is a possibility of using two irons at the same timeWhat about stand sensing feature, you will loose it ( to sense only one pen is uncomfortable )
1 x C245 and 1 x C210
