To say it’s been another challenging year would be an understatement, but it’s reassuring to see that the top 10 Arduino blog posts of 2021 show us that makers have persevered, undaunted. As we sprint headlong into 2022 with hope for a return to normality (whatever that might actually look like!) we wanted to cast […]
3D printers are very popular in the maker community and CNC machines complement them well. While 3D printers fabricate parts by adding material over time, CNC mills and routers fabricate parts by subtracting material. That is preferable when working with large parts or when you require a lot of precision. If you want an affordable […]
Makerspace i3Detroit was the recent recipient of a free yet non-functioning CNC router. While out of commission when received, the device’s mechanical components and motors appeared to be in operational condition, plus it had a large work surface. The decision was made to get the CNC up and running for now, with the eventual goal of […]
In order to get a good cut with a CNC router, the cutting tool speed needs to be properly set. Since his CNC didn’t come with RPM feedback, Troy Barbour came up with his own solution using an Arduino Nano along with an IR emitter/sensor pair. The spindle was set up with a single reflective surface, […]
