- Use (3) M5 x 25mm rounded hex screws & (1) M5x18 small socket head cap screws through the Y-axis module (Left) to connect the X-axis module. Keep screws loosely installed for now.
- Tighten the screws in a cross pattern as shown below.
STEP 2 Installing Aluminum Profiles
What you need
Part 1: Installing Front Aluminum Profile
-
1. Uninstall the (2) rounded hex screws in the slider nut at the front bottom of the Y-axis modules. - Place the profile on the front side of the machine as shown in the figure. Then use the (2) unscrewed rounded hex screws through the profile to connect the Y-axis module. Keep the screws loose for now.
- Push the profile to stick to the front of the Y-axis modules, then use (4) M5 x 25mm rounded hex screws through the front baffle to connect the profile. Keep the screws loose for now.
- Move the X-axis module to the Y-axis front baffle and then tighten them, like shown below.
Part 2: Installing Rear Aluminum Profile
- Uninstall the (2) rounded hex screws in the slider nut at the rear bottom of the Y-axis modules.
- Place the profile on the rear side of the machine as shown in the figure. Then use the (2) rounded hex head screws through the profile to connect the Y-axis module. Pre-installed screws, please do not lock.
- Push the profile to stick to the rear of the Y-axis modules, then use (4) MS x 25mm rounded hex screws through the rear baffle to connect the profile. Keep the screws loose for now.
- Move the X-axis module to the Y-axis rear baffle and then tighten the screws.
- Tighten the last rounded hex head screws in the profiles as shown.
STEP 3 Installing Rubber Feet
What you need
- Install (4) rubber feet onto the profiles with M3x20 socket head cap screws.
STEP 4 Installing XZ Axis Assembly
What you need
- Snap the Z-axis module into the X-axis slider notch.
- Adjust the Z-axis slider to a position that does not interfere with screw mounting by unscrewing the Z-axis motor handwheel. Install the Z-axis slider on the bracket with the (4) M5x14 rounded hex screws.
STEP 5 Installing the Spoilboard
What you need
- Use (12) M5 x 22mm socket head cap screws through the MDF board overhangs to attach to the profile.
STEP 6 Installing the Belt Tensioner

Software Setup
Driver Installation
Install the driver (software—+Driver—+CH340SER.exe).
To Determine your Machines’ COM port
- Windows XP: Right click on “My Computer”, select “Manage”, select “Device Manager”.
- 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”.
Grblcontrol (Candle) Connecting to the Controller
- First time use will require you to set up the appropriate COM PORT and Baud rate.
- Step 1: 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.
Test Project
Grblcontrol (Candle)

- Step 2: Click on the manual operation panel, move the spindle to the starting. Point of the engraving, so that the tool and the workpiece just touch.
- Step 3: Click [ZeroXY] [Zero Z] Clear the XYZ axis coordinate.
- Step 4: Click [Send] running G-code.
About firmware parameters
The parameters of the control board have been configured according to 4040

Z Probe Setup
Probe function introduction
- Grbicontrol (Candle) Probe operating instructions
- Step 1: Probe commands editing.
Explanation
| G21G91 | metric, relative coordinates |
|---|---|
| G21G91 | metric, relative moves |
| G38.2Z-20.17F100 | probe 20.17 mm@ 100 mmpm |
| GOZ1 | move up 1 mm (it’s in relative, not absolute mode) |
| G38.2Z-2FO | probe 2 mm$ 100 mmpm |
| G92Z20.1 | my probe thickness, YMMV |
| G90 | back to absolute mode |
| GOZ25 | retract off 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 Grblcontrol (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.
