Setting up Klipper – Let’s play
Like OctoPrint, klipper will run in it’s own dedicated virtual environment. We will setup a user for it to run as (klipper) and grant that the limited rights that it needs to run. Setup user account Option 1) Using the automated scripts… Setup Klipper by the automated scripts and install with Python2 Allow sudo access…

Powerups for OctoPrint
There are some additional steps you can take to enable the limited OctoPrint user to do more, as well as some choice plugins that will make your OctoPrint experience better. Here I will take you through some of those steps. I’m assuming you have followed my earlier blog post about how to Setup Octoprint from…

The importance of testing
Be it with a test circuit, or a simulator, test everything. Some things are so glaringly obvious that you don’t need to, but when it comes to power electronics, I cannot overstate the need for reading the data sheets. MOSFETs (Metal Oxise Semiconductor Field Effect Transistors – try saying that after a few drinks) are…

RepRap Electronics
Christmas and New Year brought a little slack time from work, and whilst I had a few hours between family and sleep, I managed to setup this website as well as start off a small electronics project for a new 3D Printer control board. The design goals were simple – make it upgradeable using off…

(2020) Proper Leadscrew Integration
The great thing about children getting older is that they sleep better, and all of a sudden you start to find that some of that free time comes back to you. With an incomplete Mendel90 looking at me every time I go into the garage, I decided now was the time to get that project…

(2017) Mendel90 Frame Fitup
Instruction sheets in one hand, allen keys in another, I set to work on the Mendel90 kit. From my past experience with FoldaRap, I knew I wanted to use ACME leadscrews for the Z-axis. FoldaRap used M5 threaded bar with 0.8mm pitch. Great for precision, but at 8000 steps per 1mm of travel, it takes…

(2017) Enter the Mendel90
Why a Mendel90? Why any 3D printer? In all honesty, I want a D-Bot (or similar derivative) – Core-XY head with the bed only moving on the Z axis. This is different to the majority of 3D printer designs today, where the head moves on the X axis, which is mounted on a gantry that…

(2017) Printing parts for RC
Before we moved house, and before we discovered that the years of practice had paid off, I had got involved in the field of Radio Control. Looking up to the skies, dreaming of what it might be like to enjoy that freedom, RC presented another way to indulge that fantasy. After playing around with a…

(2017) ReCalibration
At the end of 2015, my wife and I moved house. We said goodbye to what had been our home for the past 7 years and moved up the road to a bigger place for our expanding family. Speaking of expanding family – babies really eat into your free time. FoldaRap went to bed and…
