CR-10 Mini Belt Centering Spacer The first mod I created for my CR-10 Mini was a X-Axis Belt Centering Spacer. While assembling my new 3D Printer I noticed that the belt that controls the x axis which moves the extruder left to right was not running down the center of the extruded aluminum chassis as intended by the manufacturer. After searching high and low for a solution the ones I found were for tensioning the belt and also center at the same time. This seemed a bit overkill to me as the belt is very easy to tension, all I needed was a spacer to offset the idler pulley. You can see the blue spacer in the picture.

To get the proper size for your spacer you will need to measure the gap between the belt and the frame inside the channel, mine was 1mm. The spacer is 2.5mm thick to allow for some squishing to get good bed adhesion for some. After the 1 minute print finishes measure the thickness of the spacer and if it is too thick. Open your slicing software and simply cut off bottom of model  as necessary.

Octoprint on a Raspberry Pi Zero W – Octopi

Raspberry Pi Zero WLook what I literally just got my hands on. Stay tuned for when I turn this into a print server for my new CR-10 Mini. This is the newest version of the Raspberry Pi Zero called the W for wireless meaning it now has built in WiFi. No more USB WiFi dongles which would take up the only available USB port on the Pi. Never have to use an SD card to print ever again. I have had OctoPrint running on my PrintrBot for years without a single problem and look forward to putting this tiny computer to work.

Pictured below is it wrapped in a case that was printed off of Thingiverse.
