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.

IntelliJ & Kotlin

Just a note about a recurring problem with IntelliJ IDEA and Kotlin, under MacOs Catalina.
Sometime appears a "Kotlin not configured" message in a Kotlin based project.

3D Printing - Updates and Problems

After some initial success prints, I started to have problems.

Basically the printer had big problems to start successfully to print the first layer, no adhesion to the plate and thus prints totally ruined.

Also, it ended up one time scratching the plate with the nozzle, sign that the leveling went berserk !

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 !!
