3D Printing - Octoprint renewal - part 1

Basically since the beginning I did use Octoprint to control my glorious Ender 3.

OctoPrint has to run somewhere, so I did use a Raspberry Pi 3B to run it but all things age and I did reach the moment to update it.

3D Printing - Covid mask #2

Crazy time !  Another 3D print of a mask that claim to protect from the virus.

I am kind of skeptical about the feasibility and functionality of such solution, then I did find some people pointing out to a project.




At this time I'm NOT endorsing in any way to use this mask as real solution since too many questions are unanswered !

3D Printing - Covid mask #1

Crazy time !
I was asked if it was feasible to print a facial mask to protect from virus, to be used by normal people or also for medical teams.

So I decided to run some tests and see first hand some feasibility and if these can somehow works.

I am kind of skeptical about the feasibility and functionality of such solution, then I did find some people pointing out to a project.

At this time I'm NOT endorsing in any way to use this mask as real solution since too many questions are unanswered and potential CO2 accumulation is possible !

3D Printing - OctoPrint camera support

Another article related to OctoPrint.

OctoPrint supports to have a camera to monitor the print area, so that remotely is possible to see how a print is going on and eventually stop it if something wrong is going on.

I had around a nice Logitech Webcam C270 and it works perfectly with OctoPrint on Raspberry Pi.

So it was only matter to find a way to attach it permanently to the printer.

3D Printing - Adding Emergency Stop Button

Another article related to OctoPrint.

Sometime things can go wrong during a print.

If using OctoPrint to start/control a print, not always you can quickly go from the printer to the website in order to cancel the print and stop the printer.
Also using the printer console require some time to go on the stop.
Would be nice to have a Stop button.

IMPORTANT !  It is assumed OctoPrint is running on a Raspberry Pi connected to the printer !!

3D Printing - Adding enclosure temperature sensor

Another article related to OctoPrint.


Having around some DHT-22 sensors used on the fHelper MQTT project and seen a direct support of them for OctoPrint, I decided to use them to measure temperature and humidity of the enclosure, handled by OctoPrint.
In this article the steps to add the sensor to the System.

The idea is to have OctoPrint capable to monitor the enclosure temperature.
It is assumed OctoPrint running over a Raspberry Pi.

3D Printing - Slicers

A slicer is a program that convert a graphic file (typically in a STL extension) in a G-code file, capable to drive the 3D Printer.


It is a very important and critical part of the 3D printing process.

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.
