Re: Really universal soldering controller Reply #3617 – November 24, 2020, 10:56:36 am Set unchanged, after removing the R7 resistance, can cool down to 150 again heated to 290 degrees, has been repeated

Now feedback a question about your design for contact hibernation. After we drew the pcb and welded it, we set it to 180 degrees, we could sleep to 180 degrees, but when we reached the set temperature, we suddenly warmed up and then cooled down, repeatedlyWho are you asking?

Re: Really universal soldering controller Reply #3620 – November 24, 2020, 11:34:03 am LM339 variant? There's no R7 on it. Where is this R7 you are talking about?Post schematics and PCB.

Re: Really universal soldering controller Reply #3625 – November 24, 2020, 12:27:23 pm We have three people according to the schematic you provide, draw pcb, three pcb, the test results are the same. That's what I'm explaining
Re: Really universal soldering controller Reply #3626 – November 24, 2020, 01:05:49 pm You don't need R7. It is on front PCB.It seems that when heater is turned on, the noise from it is penetrating the sensor.Try adding 100p - 1n capacitor parallel to D2.
Re: Really universal soldering controller Reply #3627 – November 24, 2020, 01:29:09 pm Thank you, I'll give it a try
Re: Really universal soldering controller Reply #3628 – November 24, 2020, 02:20:13 pm Thanks to sparkybg for bringing such a good creative project, with low cost, we have made perfect use of JBC and a lot of iron! Thanks from the heart! Is it reasonable to see someone selling in public for their own benefit?
Re: Really universal soldering controller Reply #3629 – November 24, 2020, 02:24:06 pm Great, so excited, or you're great, my friend, D2 and 103 capacitors, the problem solved, thank you very much for your guidance. By the way, with USB brush firmware some of the screen appears black screen, but can actually burn in, before my friend mentioned to reduce the spi speed to 6, the problem can be solved, he tried
