Hi. I have a Prusa i3 3D printer and I need to add a rain sensor to the Arduino Mega on it. How would I go about doing this?

"Are your translators malfunctioning?”

rain sensor



And what is the printer meant to do when it detects rain? print an umbrella?

You would have to allocate pins in firmware,I had one on a printer I had in the garden,when it rained it stopped printing,it only worked once so I gave up

When it rains, the SD print should pause until it stops raining. How do I add this code onto the marlin files?

I am new to the Marlin Firmware so how do I add code onto the marlin firmware?

Since no one else asked, I will: Why will you pause printing when it rains?

There's a whole other part to the project. The printer has an enclosure which has a door that is opened by the printing bed moving forward at the end of the print. So if the print is paused, the door wont be opened and the printer wont get wet.

Interesting...

You can connect the digital output of the Rain Sensor to the Filament Runout Sensor pin of your control board.
This will execute M600 gcode when rain and Pause printing until you Resume it.
Not perfect, but posible.

If the end of the print is the only reason to install a rain detector: I think the reason why your door opens is because your printer is homing at the end. So replacing this command by a position which does not open the door is easier than installing the detector.

A rain detector would be interesting if you print your house with concrete ;-)

Hi. That was my plan but I have marlin files that don't have the filament runout sensor code. How do i add it on?

Maybe it seems natural to others here to place a printer outdoors, exposed to the weather, but I'm a little dense. I'm still trying to figure out why the printer is outdoors where it is going to get wet when it rains, and why it has a door that opens automatically at the end of a print, especially if the printer is located outdoors. Why not put it in the house or garage? Why not have the operator open the door to remove the print when it isn't raining?
