3D Printing - Tests

After tests, finally found a decent slicer running on Linux and Mac : Ultimaker Cura, but I found the version 3.6.0 working much much better than the latest one (4.4.1)

Let see some print finally, after changing the bed calibration springs, re-calibrate the printer and cleaning up the printing area.

3D Printing - OctoPrint

Many 3D printers, including the one I choose, the Ender 3 Pro, can be autonomous, meaning you simply save the file you want to print on a SD card, insert it in the printer and start the print.

However is much better to be able to monitor remotely what the printer is doing and even load remotely the file to be printed.

OctoPrint allows to do so.

3D Printing - Ender 3 Pro USB powering problem

The  problem arise when the Ender 3 Pro is connected to a computer via USB.

The connection between the two is via USB and the connection bring also the power (+5V).

In my case the computer is a Raspberry Pi 4 running OctoPrint.

Generic RFID 125 kHz reader

Years ago I did buy a small and inexpensive 125 kHz RFID reader.
This article would be a kind of datasheet/notes of this reader and suggestions about how to use it.

3D Printing - Vocabulary

Like all the technologies, 3D print is not an exception and it has some "lingo", its own set of words to describe specifically something or some operations.

This post will be updated often.

Let see some of them to better understand this business.

3D Printing - The beginning

Time to buy, install and use a 3D printer.

What exactly should be done before to buy a 3D printer ? What is necessary to know ?
How to choose a printer ? 

My experience.

A developer venting out

Venting out time !
After more than 35 years being a software/firmware developer, one thing that did not improve in this line of work, is the complexity of the developing environments.
It become worse, not better.
If you are not a software developer, stop to read here :) Boring stuff ahead.
