Constructing your personal CNC router isn’t precisely onerous. For not less than a decade now, enterprising makers have been firing up their 3D printers, reducing electrical conduit, soldering stepper motor drivers, and making their very own CNC routers. One drawback with plenty of these builds is the flexibility to regulate the velocity of the off-the-shelf router which is used because the router a part of a CNC router. The GRBL_SPD is a Makita Router Integration Board used to manage the ability and velocity of the ‘commonplace’ Makita 701C router through GRBL.
By connecting the GRBL_SPD to an bizarre Arduino, any CNC router can have software program management over the router’s RPM (from 10,000 to 30,000) and the on/off states. This implies you received’t have to regulate the inventory velocity dial on the router whereas it’s shifting round on the CNC. That is additionally the safer option to do velocity changes on a do-it-yourself CNC as a result of you’ll be able to alter the velocity on a pc as an alternative of dangling fleshy bits over a spinning router.
The GRBL_SPD comes with the required circuit board and a 10A relay, but it surely does require you to connect the router to the board with 5 wires, and extra wiring for the handbook management field. It’s not tough, however since each homebrew CNC router is totally different, there’s a little bit of engineering and planning you’ll have to take action the GRBL_SPD may be utterly built-in into your electronics setup.
