CNCjogger has two parts: the CNCjogger app (free, runs on your iPhone or Android phone) and the CNCjogger Stick (a small USB receiver that plugs into your CNC computer). The app sends jog commands wirelessly to the Stick, which types them as keyboard shortcuts into your CNC software.
Android is now supported. If you purchased your CNCjogger Stick before we rolled out Android support (June 2026), the device you already own works with Android too — just run the firmware update first with our simple update tool: firmware.cncjogger.com
No tools, no assembly, no software to install on your computer. Works with any Mac or Windows CNC computer with a USB port.
The LED will blink blue once per second — this means it's powered and waiting to connect.
macOS users: When you first plug in the CNCjogger Stick, macOS may show a Keyboard Setup Assistant window. Just close it — no configuration is needed.
Requires iOS 16 or later (iPhone) or Android 8.0 or later.
Tap the gear icon to select the software running on your CNC computer:
On your CNC computer, open your CNC control software and navigate to the jog screen. Make sure the window is in the foreground and ready to receive keyboard input.
Update the firmware — particularly if you purchased before Android support rolled out in June 2026. The firmware on your device may predate Android support. The free update tool takes about 2 minutes: firmware.cncjogger.com. After updating, restart the CNCjogger app and it will connect normally.
If the app stays on "Searching..." for more than 10–15 seconds, the quickest fix is to unplug the CNCjogger Stick, wait 10 seconds, and replug it. It should reconnect within a few seconds.
If that doesn't help, work through these in order:
This usually means the phone has a stale Bluetooth connection cached — the app's "Connected" indicator points at a previous session that's no longer live. Fastest fix:
If the buttons start typing characters into a text field but your CNC still doesn't move, see "Jog buttons don't move the CNC" below.
CNCjogger works by sending standard keyboard shortcuts to your CNC software — exactly the same keystrokes a regular keyboard would send. A good first step is to test with a regular keyboard plugged into the same computer: try the jog keyboard shortcuts for your software (see the software-specific notes below) and confirm that the machine actually moves. If the regular keyboard successfully jogs the machine, CNCjogger will too. If even the regular keyboard doesn't jog, the issue is in your CNC software or OS settings, not CNCjogger.
If the regular keyboard doesn't jog either, possible reasons include custom keybindings in your CNC software, a jog mode or keyboard toggle that needs to be enabled, or OS-level keyboard settings affecting input.
Software-specific:
This is normal. Return to CNCjogger — it reconnects automatically in 5–10 seconds. If it doesn't, toggle Bluetooth off/on or force-quit and reopen.
The CNCjogger Stick connects to one phone at a time. To use it with a different phone, close the CNCjogger app on the first phone. The CNCjogger Stick will automatically find and connect to the new phone within a few seconds.
If you are using a laptop on battery power, check your power settings to ensure the computer is not configured to sleep or turn off power to USB accessories. If the CNCjogger Stick does power off by accident, unplug and replug it to force the computer to restart sending power to the device.
If none of these steps help, contact us — we're happy to help sort it out.
Never use CNCjogger to jog while the spindle or router is running. Always confirm the spindle is off before jogging. Jogging into a workpiece with a spinning tool can break the cutting tool, damage the workpiece, and send debris flying.
CNCjogger is a wireless remote control, not a safety device. In any emergency, use your CNC machine's emergency stop button — not your phone. CNCjogger does not monitor machine state, tool position, or limit switches.
On first use, test at minimal jog speeds with no tool loaded. Confirm that each direction moves the machine the way you expect before working near a workpiece.
Always follow your CNC manufacturer's safety guidelines. CNCjogger sends the same keyboard commands as a physical keyboard. It does not override or bypass any safety features built into your CNC software or hardware.
