3d Printer PID tuning

In first work problems, my 3d printer needs tuning after some surface changes in my print bed. It is acting drunk right now when it tries to keep a steady temperature:

Recv: PID Autotune finished! Put the last Kp, Ki and Kd constants from below into Configuration.h
Recv: #define DEFAULT_Kp 18.74
Recv: #define DEFAULT_Ki 1.53

Recv: ok

Woody Prusa 3d Printer Repair Time

I've got some sort of problem in my 3d printer with the bed leveling probe, which is a proximity probe the printer uses to figure out how hight the print head is from the print bed.

It is probably a wiring problem; wiring is by far my weakest skill in playing with 3d printers. I probably have some dodgy tiny wiring problem in a solder joint or a splitter cable. I figure after 2 years by

When I first built the printer I had some trouble with probing. I thought it was a problem with the probe or my setup but it was the particular bed surface.

Anyway I have a spare probe and also found a supplier of a splitter cable I need, so one of those things is likely to fix my problem. I'll start with the splitter cable change, from my dodgy part which is a three way solder of three cables to a professionally assembled one without any soldered wires.

A guide about the splitting and which wire goes which way is here, along with some Marlin config things.

Minor Print List

 I fixed a problem with my 3d printer, a bad wire to a heat sensor.

The first print list item is a weird little tool for a mountain bike wheel that seats an end cap.

Second item is a replacement part cooling duct thing. This one seems fine:
