OctoPrint is an effective way to observe your printer, particularly with the addition of a webcam. Utilizing a pill or cell phone, you possibly can control what the printer is doing from anyplace in the home (or world, in the event you take the right precautions), saving you from having to take a seat with the printer as if it’s an toddler. However merely watching your printer do its factor is barely a small slice of the performance provided by OctoPrint’s huge plugin neighborhood.
As [Jeremy S Cook] demonstrates, it’s pretty simple to add power control for the printer and auxiliary lighting to your OctoPrint setup. Having the ability to flick the lights on over the print mattress is clearly a giant assist when monitoring it by way of webcam, and the flexibility to show the printer off can present some peace of thoughts after the print has accomplished. If you happen to’re notably courageous it additionally means you would energy on the printer and begin a print fully remotely, however good luck if that first layer doesn’t go down completely.
By way of , you solely want some three.3V relays for the Raspberry Pi operating OctoPrint to set off, and an enclosure to place the wiring in. [Jeremy] makes use of just one relay on this setup to energy the printer and lights directly, however with some adjustment to the software program, you would get unbiased management if that’s one thing you’re after.
On the software program facet [Jeremy] is utilizing an OctoPrint plugin called “PSU Control”, which is definitely meant for controlling an ATX PSU from the Pi’s GPIO pins, however the precept is shut sufficient to throw a relay. Different plugins exist which permit for controlling a wider away of units and GPIO pins if you wish to make a totally distant managed enclosure. Plus you possibly can at all times whip up your individual OctoPrint plugin in the event you don’t discover something that fairly meets your switching wants.
[Jeremy] previously documented his unique mount to maintain his Raspberry Pi and digital camera pointed at his printer, which is of course essential if you wish to create some cool videos with Octolapse.
