Pid Demonstration RIG part 3: The Build Video

It has been a long time in the making but now it is finally here. The companion video to my articles in the PID regulator series. It isn’t much and there are some things I will do differently in the future but for a first video I have to say I am pleased with it. […]

PID demonstration RIG Part 2: Hardware

If you haven’t read PID Demonstration RIG part 1: Software I highly advise you to do so before continuing, otherwise it might be a bit hard to follow along. When building stuff like this it is really awesome to have a 3D printer If you can come up with an idea and model it in […]

How not to build a 3D printer

How not to build a 3D printer I have a 3D printer. It’s a Cartesian printer with a build volume of 300×300x280mm and it is controlled with a RAMPS board on a Arduino Mega running the software Repetier. It’s frame is based on extruded aluminium profile and the rest of the hardware is milled aluminium. […]

Introduction What is a PID regulator? The short answer is that it is an automated control function. The long answer could fill a couple of textbooks. Because of this I won’t delve to deep into the subject but I have an upcoming project that utilises a PI regulator so writing some form of introduction seemed […]
