These are three variables of an algorithm which is supposed to keep the temperature stable. By executing a PID tuning, the printer heats up the desired heating element (extruder or bed) to a given temperature, cools down again a few degrees and heats up again for a given amount of circles and measures the fluctuation. After the process is done, you'll then get an output of three values P, I and D and save them to the firmware. It's advisable to execute a PID tuning for both the extruder and the bed before you want to use your printer for the first time. diff --git a/docs/firmware/fw_klipper.md b/docs/firmware/fw_klipper.md index efd4f001..43e20a67 100644 --- a/docs/firmware/fw_klipper.md +++ b/docs/firmware/fw_klipper.md @@ -15,7 +15,7 @@ The [Huada HC32F460 MCU](https://github.com/Klipper3d/klipper/commit/72b6bd7efa1 - It should already be mentioned here that you can always go back to the stock firmware by just re-flashing it, so you might just want to give Klipper a try. - Be aware of the fact that the control unit and display of the printer doesn't work after flashing Klipper due to the fact that the SPI the unit is connected to isn't supported by Klipper yet.
