Creality Ender 5 Configuration

XTL

I finally found some time and energy to get back to the Ender. I had a few fans swapped, but otherwise things seem to work. I ran the PID tunings, leveled the bed and printed some small bits. First parts out of the Ender and Duet! It really is amazingly quiet for its movements but the full set of fans is still a lot of noise.

Next is figuring out parameters, pressure advance(?), speeds etc.

My PIDs ended up at: (edit: new therm values)

I presume that looks sane?

Going to be starting this project myself shortly. Good to have some starting Values.

The D value for the bed heater (1.2 seconds) looks suspiciously low, although low values are not unusual if you are using a silicone heater with a built-in thermistor. I suggest you heat the bed to printing temperature, then watch the temperature carefully to see whether it is stable. If you see it oscillating regularly above and below the set temperature, try a larger D value such as 5. The other parameters look normal to me.
