I have a long term goal of eventually upgrading my Ender 5 plus to have true automatic bed leveling, but the first stop towards that destination is being able to control 3 Z steppers independently. The method I’ve chosen to do this is upgrading the mainboard from the SKR Mini E3 v2 to an Octopus […]
1x Cereal Dispenser 1x Ramps 1.6 Board 5x A4988 motor drivers 1x Arduino Mega Just a normal one for now, but I have one with an integrated ESP32 on order 4x Nema17 17HS4023 Stepper Motors The RAMPs parts came before the Arduino, so I designed and 3D printed a shaft for the auger and a […]
Apparently the stock firmware of my 3D printer (Monoprice Maker Select 3D v2) is missing a critical feature where it detects thermal runaway and safely shuts down. The failure mode would basically be if the thermocouple on the hotend breaks, the printer will continuously pump power into it trying to get it up to temperature, […]
As one of my previous posts showed off, I made a wall mounted Home Assistant Dashboard. It was based off of the official 7″ Raspberry Pi Foundation touch screen. I designed the enclosure myself, mostly working from the touchscreen dimensions here and then some rough measurements on the rest of the BOM. Bill of Material […]
The last post ended with me setting up a z-wave switch with the intention of using it to control the power of my 3D printer, so that’s what I’ll cover here. I’ll also set up another Pi with Octoprint so that I can send gcode to the printer remotely. Home Assistant – Z-wave Switch with […]
I bought this switch from Monoprice with the intention of using it with my 3D printer. Partly so that I can turn it off and on remotely, but also so that I can see how much energy it uses. It is easy enough to set up, follow the inclusion mode instructions here and plug the z-wave […]
The motivation behind this was to recreate a feature of Melissa’s aunts security system. Mel always liked that the doors in her aunts house all triggered a chime to play in the house when they were opened. This is a small feature of their alarm system and should be fairly easy to re-create with Home […]
Again, this is less of a guide to 3D printer than it is documentation on my 3D printing set up. Hopefully it can do both, but that remains to be seen. For my first (and at the time of writing this, only) 3D printer, I chose the Monoprice Maker Select 3D v2. This is a […]
