The issue I have with your FW is that also the (genuine JBC) T245 settings are not correct. I am not going to fiddle with parameters in the menu because I have insufficient knowledge of the actual effects. And moreover, the original settings in the FW by sparky are perfect.
Could you make available your FW with original settings, not adjusted by you and your friends please? If not possible, could you please post your uncompiled FW? I am sure we will have enough people here that will be able to compile a version with the original FW settings
The problem is in your tip parameters because on the original FW I get a very close match between T245 and T210. T210 is a bit hotter, about 4 degrees.
I think you changed the parameters on both irons in your FW because with your FW, I need a lot of adjustment on the trimmer resistor to get T245 at correct melting temp compared to the original FW, and the T210 is way off: about 35 degrees hotter than T245, which is what you describe.
Re-flashing the original FW results in perfect behavior of both irons at my original trimmer resistor setting, which closely corresponds to the 10ohm initial setting.
Unfortunately your FW will not be workable unless you change back to the original iron settings. Which FW build version did you use as a basis for your FW? I know Sparky changed the iron parameters in the latest one because he found an error in the previous versions. Could it be that you did not use the latest one?
I used the original T210 in the original firmware, which is 30 degrees lower, so I can only modify the firmware parameters. But maybe the T210 made in China is 30 degrees higher than the original version, so your temperature is accurate in the original firmware, but by what standard, at least my friends around me got the same result as me. Use the original 210, the original firmware is 30 degrees lower. This firmware can have C1 parameter in IRON CFG under the menu, and C1 can be adjusted to get the desired effect
Difference between my T245 and T210 is a few degrees, depending on tip type. T245 is original JBC with original tips, the T210 is a Chinese copy.
So the profiles that Sparky designed work well.
I suggest you test it with the original 210. As far as I know, the temperature of many Chinese copied 210 is tens of degrees higher than the original one. There may be some temperature that is the same as the original one. If you just bought it, the temperature is higher than the original one. If the original temperature is high, it will become the same temperature on the unisolder, because we use the original 245 and the original 210 to compare, the 210 temperature is 30 degrees lower
Did you test for the correct Temp with nonmodified sparky's profiles
In fact, my friends and I failed to get the correct temperature using the unmodified configuration file, and the difference between 245 and 210 is 30 degrees. My friends are all the same phenomenon, maybe something is different from sparkybg, Some people use the same genuine device purchased from the original bom, and some people use Chinese substitute devices, but the results are the same, which is not ideal, so we have the idea to modify the configuration file
I made and tested a lot of handles, such as jbc210/jbc245/jbc470/hakko t22/hakko 2024 solder suction device/weller rtm/weller electric tweezers/ersa wind pen, only jbc210 and jbc245 have suitable dormant brackets, others are not available for the time being A suitable bracket is available, and many friends may also have such troubles. The power dormancy is only used as a supplement or temporary use. Provide a new idea
It is nice to read and learn more about these extra features by Catear but anyone in here likes the idea of having the sleep function in auto mode while the Iron in your hand?
I am trying hard to understand the purpose of this feature and how It will be used on real PCB while soldering. The rest of the features might be useful.
This function can be turned on or off, and you can specify a separate switch for a certain handle, use it if you need it, or turn it off if you don’t need it. No one will force you to use it.
Modifying C1 on a profile that has many coefficients (thermocouple or PTC), may produce highly unexpected results, since it is a non-linear polynomial. Just bear in mind. My intention as these coefficients to be changed and saved in windows software, but... as I said several times, I am very short of time and I don't know when this will happen.
Perhaps, you can list all polynomial values in the case of polynomials. I have not used polynomial handles. Host computer modification is the best method, but I am not familiar with the host computer code.
I was just about quick enough to catch the ST vs HT display error I mentioned. I was almost too late but if you look carefully, you see that on the first second of the video, the temp is still on holder temp (252 C). The display is on ST
