I’m having issues with the PID. Everything is seems to be connected according to the provided schematics, and all components work, we’ve measured them. As you can see on the picture, the PID gets the correct temperature from the thermocouples, currently 33, and is set to heat until 200. However, it doesn’t signal to the SSR’s to power the band heaters.
We’ve measured it through, and the PID is powered and signaled properly, but it doesn’t give output signals at nr. 4 and 5 (and 3).
Does anyone have any idea what could be the problem, and how to fix it? I’m pretty sure it’s not a broken PID, because we have the same issue with all four of them (2x at extrusion and 2x at injection, no compression built yet). But I have no clue what could be another reason…
