Ender 3 with Marlin – How to Install Marlin Firmware on Your Ender 3

Ender 3 Marlin What is Marlin Firmware? Marlin firmware is the world’s most popular 3D printer firmware. It runs on an 8-bit controller board, making it affordable, and it’s fully open source and free to use. It’s ideal for companies like Creality, who produces the Ender 3, to modify and add to their machines. While the Ender 3 is a great machine – it was even our winter 2018/19 pick for the “Best 3D Printe ...

Smart 3D Printer Filament Counter (FilamentBot)

For 3D makers the worst thing is running out filament in the middle of a hours long print. This device will order for you when it is low! Introduction The FilamentBot is a Amazon Dash Replenishment Service (DRS) enabled smart filament counter that will contentiously track the filament usage by measuring the actual length of the filament that has been dispensed on any 3D printer, and automatically re-order t ...

DIY Mini Quadcopter with 3D-Printed Frame and Custom Firmware

I wanted to try my hand at a true "DIY" project, designing and building my own micro quadcotper frame and writing my own firmware in C++.  In this post I will describe the frame and build; in my next post I will talk about the firmware. Excluding stuff I had lying around the shop, (heat-shrink tubing, EC-3 connectors, velcro, cable ties, etc.) the cost came to just under $170: 3D-printed frame "free"! Fligh ...

Automatic Pet Feeder using Arduino

Today we are building an Arduino based Automatic Pet Feeder which can automatically serve food to your pet timely. It has a DS3231 RTC (Real Time Clock) Module, which used to set time and date on which your pet should be given food. So, by setting up the time according to your pet’s eating schedule, the device drop or fill the food bowl automatically. In this circuit, we are using a 16*2 LCD to display the ...

Panelizing and Gerber Generation in Eagle

Story I have been working with Eagle for quite some time but never really got a PCB manufactured. almost all the time i used the toner transfer method to make homebrew PCBs. But then i took a project in which i had to use SMD components and i could no longer use toner transfer method because of the limits on resolution of the Laser printer. Time had come for “properly” designing and generating “Gerber files ...

Photon Printer – Micro Laser Engraver

The Photon Printer is a 3D printable laser engraver made from recycled DVD Drives. A list of necessary components is in the instructions. The Photon Printer started out as a quick weekend project then quickly escalated when I saw that there was room for improvement in the current designs. The design turned out to be quite fun and I really enjoyed seeing it work at the end. Safety - None of the designs I hav ...

Homemade arduino printer

If you want to make your own high resolution printer (maybe not so high res), you are at the right place. This Instructable will show you how to do with two dead cd/dvd drive and a pen (pilot, whiteboard marker, whatever you have) at the best lego-printer style. Here is how our printer will work: we type any message in terminal then the message will be printed (as dot matrix) and after the message is printe ...
