This prepares you Arduino as GRBL controller.Ĭheck first that wires from the back of the box to the connectors on the proteneer card are long enough. Run that command with Arduino connected in USB. the path to the Arduino installation that dépends on IDE version and may differ on you PC Select your Arduino board from the Arduino IDE Tools > Board then select your Arduino board's port from the Tools > Port menu.Ĭ:\Program Files (x86)\Arduino- 1.8.3\hardware\tools\avr/bin/avrdude -CC:\Program Files (x86)\arduino- 1.8.3\hardware\tools\avr/etc/nf -v -patmega328p -carduino -P COM3 -b115200 -D -Uflash:w: C:\Users\berdeter\Downloads/grbl_v1.1h.20190825.hex:iĬarefully check and adapt the command, especially the parts in bold : Take the hex file from the latest release.ĭownload and install Arduino IDE from here : Let's start by installing GRBL firmware on your Arduino UNO Limit switches (I'll develop that later) : I did my first experiments with a 6mm bit that is much more robust than the 1/8 standard bit. And of course, un computer to drive the thing. A small screwdriver and a multimeter are also useful.
You'll have some soldering to do so you need obviously need an iron for that. The shield (Proteneer v3.51) - be sure to have at least that version, and not version 4 that is for Arduino Nano : Universal GCode Sender and GRBL 1.1 become well supported softwares and are definitly better than Mach3 or CNCUSB - I'll also give configuration and first use hints. It requires either a parallel port and Mach3 commercial software or USB with CNCUSB but no driver is available for windows 10 and CNCUSB is not available under Linux - CNCUSB is a mysterious controller software and it's not clear which post processor is to be used in Fusion 360 - The machine definitly needs limit switches for homing and to prevent crashes - a Zero probe is a nice to have - TMC2209 will bring silence in steppers and is more accurate.
Problems this upgrade address are : - the driver board in the CNC is not compatible with modern computers. Upgrade it !Īfter a bitof research I decided to give it a go on basic of a simple Arduino UNO and some additional devices. The driver card was too old and did not support Windows 10 or Linux. Delivered from Germany it arrived in Belgium in 2 days but hummm it was unusable. I've ordered my Chinese CNC 3040T on Ali Express.
