There are many tutorials that you can follow on the internet if this weekend you want to carry out some other project on your Raspberry Pi, this time I propose one in which, with several pieces that we can take from an old computer that we have for house, let's build our own printer. For this we are going to literally need parts taken from a CD reader unit, specifically its motors, a servo, four H bridges and our Raspberry Pi.
Before starting, tell you something very important, such as the fact that, if your reading unit is too old, you may not be able to carry out the entire project, it is best to make sure since not all readers were equipped with stepper motors at the time So, before you even start, it would be interesting if you did this check, once done you can continue following all the steps that you have in video just below these lines.
If you are interested in a much more detailed step by step you do not have to worry since the author of this tutorial, known in the community as HomoFaciens, has posted all the material in his Web page as well as the source code necessary to run the entire project. Undoubtedly, we are talking about a rather complex project that can leave anyone with their mouths open, especially because of its peculiarities.
