![]() ![]() #CHEAP REFLOW OVEN CODE#Too much debugging code and this code is also very old. For now I’ll be very conservative and work my way up.Īlso need to do some major code clean up and add comments. ![]() Not a major issue but I will likely burn more than a board or two while I try to dial this in. Since the elements stay hot even when it’s off I need to fine tune it to a lower threshold to allow for this extra temperature rise and I need to add more of a delay between profile steps to compensate for this. I now have a toaster oven that follows a standard solder profile albeit not incredibly accurate at the moment. Lo and behold, I did that same thing and it works. ![]() I haven’t had this particular issue before but I have had issues where the debugger would act strange but if I programmed the chip directly, everything worked fine. Then I figured it was probably the debugger. The chip has brown out protection and the dip is very quick. I could fix this with a large filter cap, and I still plan to for another build, but I didn’t understand why it was so sensitive. Thought it may be an issue with the voltage dipping due to the large current draw of the toaster oven during turn on. I’ve also added a sub thermocouple reader as an alternative so I’m not consistently removing and adding back in the same two parts.Īfter some code cleanup I had a system that seemed to work when simulated but, for some reason, when I attached the toaster oven at the output it would cause the chip to seemingly latch. Not as much control but honestly I don’t need that level for home projects. Onto revision two where I’ve replaced the triac with a simple high power relay.
