Filament "pull" affecting 3D print performance

Friction in the filament feed path can affect 3D printer performance...

 

...or at least that is the conclusion I have come to over the last few days.

Here are my notes to back this up.

Playing with colour recognition #2: resistor value reader

This post is about a practical example of colour recognition.

 

It describes an experiment to determine resistor values from their coloured bands.

Its an interesting, but difficult task.

3D Printing: sticking and removing

This post is primarily concerned with 2 issues;

 

1) Getting your prints to stick to the bed

2) Getting your prints off the bed

3D Printing: I'm back in the saddle!

It is almost 8 years since I've posted anything on 3D printing.

 

That's largely because its almost 8 years since I last touched a 3D printer.

Well now that I have my own printer...I'm back!

Prostate Cancer: "F" is for.... Fiducial

My first concern was unfounded, as it turns out they are quite small.

However, the second concern proved to be more justified.
