STEP 1: Installing Rubber Feet
What you need:
- Flip the XY-axis base assembly upside down.
- Place the (4) M4 T-nut into the slot and thread the (4) M4x10 screws through the rubber feet, as shown. Then tighten the screws.
STEP 2: Installing X-axis Assembly
What you need:
Mount the XZ-axis assembly on the XY-axis base assembly and use (16) M5x25 screws to lock the assembly from each side.
STEP 3: Installing the Spindle Motor Mount
What you need:
- Attach the spindle motor mount to the Z-axis clamp mounting plate and align the screw holes on both sides.
- Use (4) M4x18mm screws through the Z-axis clamp mounting plate to install the spindle motor mount.
(Note: Do not tighten screws fully, keep loosened for now.)
STEP 4: Installing the Spindle Kit
What you need:
- Use the 10mm wrench to hold the router in place and the 17mm wrench to unscrew the collet nut on the 710W router.
- Push the collet into the collet nut toward the arrow until a click is heard, indicating that the collet is in place.
Collet Replacement Instruction
Remove the collet nut.- Press the collet in the direction of the arrow to separate it from the collet nut.
- Place the collet to be replaced in the collet nut and push the collet into the collet nut in the direction of the arrow until a click is heard, indicating that the collet is in place.
STEP 5: Installing the Spindle
What you need:
- Insert the spindle into the spindle motor mount and note that the spindle switch is facing forward.
- Use (2) M4x18mm screws to fix the spindle to the motor mount.
Plus, in the spindle power cord, make sure the power cord is plugged in completely, as shown. Then tiahten all screws.
STEP 6: Wiring
Control Board Overview
Plug the Y-axis motor or cable and the Y-axis limit switch cable into the control board as shown. (The rest of the cables are connected.)
STEP 7: Installing the Clamp Kit
What you need:
- The clamp kit includes the following components, as shown.
- Adjust the position of the clamp kit according to the size of the workpiece to be engraved. Screw the screw into the threaded holes of the aluminum countertop first, then set the spring, nylon gasket, plate, and column, and finally lock the nut.
The Laser Module shown below is sold separately.
What you need:
- If the retaining ring is slightly tight, expand it slightly with the help of a tool and place the laser module in it, see below.
If the retaining ring cannot fit into the spindle motor mount, then uninstall the 2 screws on the spindle motor mount, and greatly loosen the 4 screws holding the spindle motor mount to the Z-axis.
Software Setup
Driver Installation
Install the driver (software→Driver→CH340SER.exe).
To determine your machine’s COM port
- Windows XP: Right-click on “My Computer”, select “Manage”, and select “Device Manager”.
- Suitable for all systems after Windows 7: Click “Start” > Right-click “Computer” > Select “Manage” > Select “Device Manager’ from the left pane.
- In the tree, expand “Ports (COM & LPT)”.
- Your machine will be the USB Serial Port (COMX), where the “X” represents the COM number, for example, COM12.
- If there are multiple USB serial ports, right-click each one and check the manufacturer, the machine will be “CH340”.
Grbl control (Candle) Connecting to the Controller.
First time use will require you to set up the appropriate COM PORT and Baud rate.
- Step 1: The software should automatically select the port number.
- Step 2: If it does not recognize automatically, select the “Baud” drop-down menu and select 115200.
- Step 3: Click “OK” to save.

- Step 4: Click [Send]to run the G-code.
About firmware parameters
The parameters of the control board have been configured according to 3020-PRO Ultra.
Z Probe Setup
Probe function introduction
Grbl control (Candle) Probe operating instructions
Step 1: Probe commands editing.
Explanation
- G21G91: metric, relative coordinates
- G21G91: metric, relative moves
- 38.2Z-20F100: probe Z-AXIS Down 20mm@100 mmpm
- GOZ1: move up 1 mm (it’s in relative, not absolute, mode
- G38.2Z-2F10: probe 2 mm $ 100 mmpm
- G92 Z12.35: my probe thickness, YMMV
- G90: Back to absolute mode
- GOZ25: retract the probe
This assumes that the user would position the probe, then jog the bit 5 or 10mm above it. With a PDF this could be copied from the PDF, pasted into Candle, and just the probe thickness changed.
Step 2: Probe commands filled in Grbl control (Candle).
Step 3: Connect the probe tool to the controller probe interface.
Step 4: Click the “Z-probe” button, Z-axis automatic tool to zero.
