You’ll need this port number when you connect your CNC GUI with the board. You can find this port number under ‘Ports (COM & LPT)’ in the Device Manager (Control Panel > Device Manager).

When the computer installs the module it also creates a numbered serial port.

With the module turned ON, your computer should be able to discover the device and install its appropriate drivers. If you are on a Windows machine, open Devices and Printers and click on ‘Add new device’. To turn ON the module, detach the cable from the computer. If you’ve connected the USB cable, the BT module will remain switched OFF. Once you’ve configured the module, Simply plug it in on the board such that the ‘KEY’ pin points to the motor controllers on the right.
However if you are using your own module, you will need to configure it using this guide. If you’ve bought the module from me, its pre-configured and you can skip straight to the connecting part. This should properly set the machine with limit switches and in your preferred coordinate space.īefore you plug in a BT module you will need to configure it with the appropriate settings. Once this is done, re-home the machine and then re-set the homing direction mask (it should be reversed again since we changed the main direction port invert mask). This is easily remedied by tweaking the direction port invert mask ($3). Right after this you’d typically see that one or more axes are reversed. I then play with the direction homing direction mask ($23) and get it to home in my preferred corner. I usually run a homing cycle and see which direction the axes move. Just be patient and if you’ve wired everything correctly, its bound to work right. You’ll then need to play with the homing direction and main direction port masks (explained below). If you’d like it otherwise, you need to enable HOMING_FORCE_SET_ORIGIN in the config.h file to set 0,0,0 to the homed location and re-upload the firmware. Note that once homing is complete, the entire machine is set in the negative coordinate space. Limit switches must be enabled through homing by setting $21=1 in the settings.
