Wireless Pendants

Wireless pendants are currently sold in three configurations in the myCNC Shop.

Setting up the wireless pendant

Upon opening Settings > Config > Panel/Pendant > Wireless Pendant/XHC, the user is presented with the following screen:

  • The indicators at the top of the page serve to visually point out the pendant button which is being pressed. There indicators will light up green when the corresponding button is pressed:

  • DSP style pendant should be disabled if the controller is used with a screen (enabled ONLY if the controller is using a PHB-04B pendant WITHOUT any monitor). This setting, when set to PHB-04B, disables a number of on-screen buttons as well as reassigns a number of the pendant button commands to a custom build. This allows for an emulation of a DSP style controller system, which eliminates the need for the monitor and is well suited for simple production runs which require limited settings changes or system configurations. It is recommended to keep this setting disabled unless strictly necessary, as it is designed for a purely pendant-oriented interface (on a system entirely without a monitor).
  • The Device List lists the available devices, while the libUSB Debug information lists the messages that the pendant sends to the computer:

  • It is possible to load the default button configurations from some of the popular wireless pendants available, as listed on the right side of the screen:

Assignable actions

If the pendant used is not listed in the defaults list, or the user wants to re-assign some of the button actions, the following options are available:

Option Description
CNC Action This brings up a preset action (listed in MyCNC Actions list). These are preset actions, and the majority of items further on the list can be done simply by inputting the relevant text into the CNC Action field. Whether to use CNC Actions or to simply choose one of the items below is left to the user.
CNC Variable: Switch This switches some global variable between set values. Example of syntax: 1000/33;22;11 where 1000 is the variable, and 33, 22, and 11 are the values the variable will switch between upon each button press or input
CNC Variable: Toggle This toggles the specified variable On and Off. Example of syntax: 1001
CNC Variable: Clear Clears a global variable
CNC Variable: Set Command to set the variable
CNC Variable: Assign Writes the variable from the Global Variables list. Example of syntax: /1001
File: Open Open a file from the host computer (brings up the dialog window)
File: Open DXF/HPGL Open a DXF/HPGL file from the folders specified in Preferences > Common
File: Refresh Refresh the program file
Hardware: Direct Binary Set Directly sets a binary to be ON
Hardware: Direct Binary Clear Sets a binary to be OFF. For example, upon inputting 15 into the field, the 15th binary will be flipped ON
Hardware: Direct DAC Set Sets the DAC. For example, input 0/160. Here, 0 is the channel number (always 0 for DAC), while 160 is the value in units. NOTE: The value displayed in the diagnostics panel in myCNC software displays the DAC value in volts, not units. Conversion is necessary based on the voltage of the power source used.
Hardware: Direct PWM Set Sets the Pulse Width Modulation. For example, 1/1600. Here, the 1 is the channel number for PWM, and 1600 is the value PWM is set to

Toggle: custom widget by name Specifies a custom widget to bring up on the screen (or close it if already displayed).
View: Zoom In Zoom in on the control program visualization
View: Zoom Out Zoom out on the control program visualization
View: Fit to window Fit the entire view into the visualization window
Work coordinate: Set Set the work coordinate (using the specified axis value from the user panel, NOT the typical pendant control)
Work coordinate: Reset Reset the work coordinate (from user panel)
Work Coordinate: 1/2 Half the work coordinate (from user panel)

These options allow the user to edit every button on their pendant control to their particular configuration if required. For simple pendants included in the defaults list, it is usually recommended to use the default settings.

XHC wireless pendant control for MS Windows

How to install XHC wireless pendant control for MS Windows:

1. Download the “Zadig” software from

2. Run the utility, select “Options menu” and check menu “List All Devices”

3. Select “USB HID” device in the displayed list (Check USB ID that starts with “10CE”)

The following ID's are available:

ID Pendant Model
eb6f PHB02, WHB02
eb93 WHB04B-6
eb92 PHB02B-6
eb91 PHB04B-6
eb70 WHB04L

4. Select “WinUSB” driver and press “Replace Driver” button, confirm driver changes.

5. Restart myCNC software, it should get access to XHC Pendant control over “libusb” driver.

XHC wireless pendant control for Linux

Pendant control on Linux should be automatic, however in case of issues it may be necessary to check the 99-xhc.rules file.

Linux has a “udev” subsystem that handles hotplug events, for instance an event when a USB device is inserted, in which case Linux reads the ID numbers, looks into udev rules, and runs the appropriate scripts. For XHC pentants, the myCNC team has a rules file with which the user is allowed to read and write data to the pentant. In order to diagnose issues, it is necessary to locate this file:


and check if it mentions the device that is currently being used (for instance, the WHB02 pendant would be 10ce:eb6f). Normally, myCNC creates this file automatically. In case it does not exist or does not contain the necessary line(s), then something is wrong.

By default, access is open to the administrator ONLY, a simple user does not have the permissions. As such, if you are running into an error while opening the file, check that your user has the necessary permissions. If the file exists, you can try to delete it, restart the software and see if the file reappears.
