Quick and Dirty X Belt Tensioning

Mendel’s X belt tension needed increasing, but this is a beggar of a job to do with the original belt clamps (I have the injuries to prove it!). Turns out there is a simple solution, inspired by the Open X Carriage – cable ties!

While this is a preferred solution to the original, it is still difficult to tension the belt beyond a certain point. Also if you change your mind and decide it needs loosening by a notch or two, that can prove to be a challenge! Ideally I’d like a tensioning system like this Y Belt Tensioner by sliptonic on both X and Y axes, but the cable tie will do for now :).

Etching Generation 7 PCBs

The premise behind the Generation 7 RepRap electronics is replicability, so we decided to fabricate our own for our Huxley in progress. Originally we had hoped to set up our Mendel for milling with our Dremel, but with our sticky y axis problem being only improved but not completely solved by increasing the belt tension, we decided to play it safe and etch the PCB instead.
