Adding a Rain Sensor to printer 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? https://reprap.org/forum/read.php?262,829347,829347#msg-829347 Sun, 06 Sep 2026 07:49:22 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,829347,835487#msg-835487 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,835487#msg-835487 the_digital_dentist Printing Thu, 04 Oct 2018 07:07:52 -0400 https://reprap.org/forum/read.php?262,829347,835482#msg-835482 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,835482#msg-835482 Yuvera Printing Thu, 04 Oct 2018 06:54:12 -0400 https://reprap.org/forum/read.php?262,829347,831521#msg-831521 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831521#msg-831521

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.

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 ;-)]]> JoergS5 Printing Sun, 19 Aug 2018 05:00:22 -0400 https://reprap.org/forum/read.php?262,829347,831506#msg-831506 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831506#msg-831506 This will execute M600 gcode when rain and Pause printing until you Resume it.
Not perfect, but posible.]]> VincentM Printing Sat, 18 Aug 2018 18:18:21 -0400 https://reprap.org/forum/read.php?262,829347,831446#msg-831446 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831446#msg-831446 the_digital_dentist Printing Fri, 17 Aug 2018 17:43:50 -0400 https://reprap.org/forum/read.php?262,829347,831441#msg-831441 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831441#msg-831441 Yuvera Printing Fri, 17 Aug 2018 14:40:40 -0400 https://reprap.org/forum/read.php?262,829347,831376#msg-831376 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831376#msg-831376

When it rains, the SD print should pause until it stops raining.

Since no one else asked, I will: Why will you pause printing when it rains?]]> the_digital_dentist Printing Thu, 16 Aug 2018 14:48:49 -0400 https://reprap.org/forum/read.php?262,829347,831368#msg-831368 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831368#msg-831368 Yuvera Printing Thu, 16 Aug 2018 13:25:52 -0400 https://reprap.org/forum/read.php?262,829347,831367#msg-831367 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,831367#msg-831367 Yuvera Printing Thu, 16 Aug 2018 13:24:24 -0400 https://reprap.org/forum/read.php?262,829347,829472#msg-829472 Re: Adding a Rain Sensor to printer https://reprap.org/forum/read.php?262,829347,829472#msg-829472

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