This section is for Windows based PCs, you can also just use the offline controller. Software for Apple Macs and Linux which do not have support for installing and running windows programs is available, but is not described here.

Step 1: Driver Installation

All files referenced should be on your SD card or mini CD, if there are any problems with accessing these you can download a full copy of it's contents of it from here.

The first step is to install the Windows Serial port driver, labeled CH340SER.exe. If you cannot find this file, you can download it again from this link. Please not that the file linked is stored in a compressed .zip file. To use, you must extract the full contents of the .zip to a designated folder, and then try running the file from there. Running files from the .zip directly will not work.

Once you have found CH340SER.exe, right click it and select 'Run as administrator' and authorize the programs to make changes to your computer. From there, just follow the installation process and you are done with this step.

Step 2: Software Installation

This is a free and open source program which talks to your PROVer (or other Grbl based routers) by a serial USB connection and provides a variety of functions. This guide refers to GrblcontrolCandle V1.1.7, referred from now on as just Candle.

Candle can also be downloaded for Windows and Linux from Here, but please keep in mind that operating instructions can be found Here as they are not included with the installer.

To install, just copy the entire contents of the directory to a folder on your computer, for example to a Program Files (x86)/grblControl directory (you will need administrator privileges for this) or anywhere else on your computer. Once copied create a shortcut to ‘Grblcontrol (Candle).exe’ and save it anywhere you wish.

To start Candle click on the shortcut or directly open the Grblcontrol (Candle).exe /motorola-e5-play-sprint-unlock-code-free.html.

The data of the GRBL 1.1 Nano control card: Connection possibility for drivers or motors for 3 axes, also several motors/drivers per axis. Then of course limit switches for all 3 axes, also 2 limit switches per axis. Relay output to switch cooling water. Probe; length sensor, touch plate, stylus etc. Can be connected in parallel. Last stable version: latest All versions: github.com/arkypita/LaserGRBL Also source code of LaserGRBL is available under GPLv3 license. LaserGRBL is free. If the maker movement was an industry, Grbl would be the industry standard. Most open source 3D printers have Grbl in their hearts. It has been adapted for use in hundreds of projects including laser cutters, automatic hand writers, hole drillers, graffiti painters and oddball drawing machines. Firstly make a note of your GRBL machine settings. Download the GRBL version you want to flash onto the controller board from GitHub. It is the ZIP file you will need. Unzip it and remember where you put it. Download the Arduino IDE and install it (if you haven’t already got it). You will need the Windows App, not the online web.

Download GRBL Windows 10 Configuration Tool for Windows to this is a configuration tool for setting up the popular GRBL CNC Machine motion controller using Windows 10. Version 1.1.0.0.

Step 3: Configuring Candle

Connect your CNC via the USB cable and start Candle. Ideally you should see something like the screenshot below:

If, instead of 'Port Opened' you have a red Alarm state in the status box, this is actually good! The 3018 and 4030 PROVer is fitted with limit switches and by default has ‘Homing’ enabled. Until a Homing Cycle has been run it will be in an Alarm state as it has no idea where the spindle is and will accept very few commands. You can also get out of this state by clicking on the padlock icon in the Control section of Candle to unlock the machine.

If you are not seeing the above image, you may see the following image below:

If this is the case, then Candle was unable to automatically find your router. Simply select the Service/Settings option from the top menu and you should see the settings menu:

Check that the Baud: value is 115200, if not change it, then Click on the connection/Port dropdown menu and select the COM port your router is connected to, there should not be many so if necessary try them each in turn. Click on OK and you should see first screen shown above, if not select the next COM port and retry.

If all else fails check the USB cable connection to the router, as well as see if the Emergency Stop button is pressed (It shouldn't be) and retry.

Before proceeding any further, check some settings:

the Machine Information section set/check the following:

Grbl 1.1 F Hex Download

Rapid Speed should be set to 2000

Spindle Speed Min should be set to 0

Spindle Speed Max should be set to 10000

Laser Power Min Should be set at 0

Laser Power Max Should be set at 10000

And hit OK. Your software is now configured and ready for use.

Grbl 1.1 Software Download

We’ve released a new firmware update for the Mill One. This update will work with all Mill Ones. Download it here:

This firmware update increases the speed and acceleration settings of the Mill One. GRBL v1.1g has general improvements and bug fixes that improve reliability and performance.

Things to know about this update (please read this carefully if you are updating your Mill One since there are some specific instructions):

• This firmware update takes the Mill One from running GRBL v1.1e to v1.1g. You can learn more about the development of GRBL on the GRBL Github.
• You can update your firmware the same way as you uploaded it the first time. Instructions can be found on our Resources pages.
• Before you start, make sure to clear your EEPROM. EEPROM is where the Arduino stores all of the GRBL settings. Some settings from GRBL v1.1e may persist if you do not clear the EEPROM. An Arduino program in the downloaded firmware folder can be uploaded to the Arduino to clear the EEPROM.
• If you have installed a library into Arduino for an older version of the firmware, you will have to delete it and replace it with the new version. You can find the old libraries in the “Arduino” folder, which can usually be found in the “Documents” directory. Go to the “Libraries” folder and delete the “grbl” folder. This will delete the library and will let you install a new ZIP library.
• Installing this update will undo and delete all your old settings. If you made any changes to the firmware, make sure to save all your settings. You can look at your settings by sending the command “$$”. If you need to make changes to your settings after the update, you can refer to the GRBL Configuration wiki.
• If you run into issues with the firmware, please let us know.

If you want to revert back to GRBL v1.1e, you can download the firmware here.
