I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...

Initially, they put an Arduino inside the control box of the CNC and it fit nicely, but it turned out the Arduino’s CPU would restart every time the spindle spun up – apparently, EMC would ...

[Reza Naima] has been using an Arduino as the center of his CNC setup for quite some time now. It handles three stepper motors, limiting switches, e-stop, and spindle control. The sketch he’s ...

This project continues a general approach to building ESP32 based CNC machines of various types. It is entirely based on the next generation FluidNC project, a hugely important codebase that I have ...

Universal (ish) Arduino grbl opto-coupler interface also works with logic-level pwm In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to ...

An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino - JimmyNXT/Ben_CNC_grbl ...

The Arduino PCB Ink Plotter CNC Machine is a DIY project that features a arduino running GRBL CNC firmware. In this project, it uses a marker that is suitable for plotting or marking the PCB for board ...

Arduino or electronic enthusiasts searching for a new project to keep them busy this weekend may be interested in the awesome Arduino controlled CNC foam cutting machine, constructed from a ...
