Recently I by mistake bought ABS pro filament instead of the PLA filament I have used. No problem with that, ABS can be better for in some cases. But it caused me one problem, the ABS needs some higher temperature when printing, when I increased the temperature from 220 to 245 degree Celsius on the 3D-printer it didn't get very stable, about +/-5 degrees fluctuations. I investigated how to solved that. I needed to optimize the P.I.D. parameters.
Here is the details how I solved it, wasn't very difficult when you know how to do it:

Now it's about +/- 1 degree Celsius. Tested in the range from 220 to 245 degree.
