The automatic tool changer allows for users to pre-load up to 6 different bits in addition to the wireless Z-probe to enable complex machining with minimal effort!
- To use the Automatic tool changer, we first must ensure that our bits have bit collars installed. These collars hold the bit securely in the tool changer (see how to install these collars below)
- To install / uninstall bits, firmly and carefully press / pull bits into any of the six holders on the tool changer.
- You can select and drop any of the bits and wireless probe by using the tool drop down menu in the Carvera Controller app.
- You can then set your design files to use bits that correspond with the locations on the holder using any of our supported CAM programs, as shown in the tutorial video, for seamless tool changing during manufacturing!

¶ How to Setup and Use the Wireless Z Probe
The Wireless Z Probe allows for users to easily setup stock for machining as the z height is automatically measured by the Carvera. Loaded as a tool with built in charging, the Wireless Z Probe is easy to use and easy to maintain.
- When setting up a new wireless probe, we can install different posts to accommodate shank diameters of 3.175 mm, 4 mm, 6 mm, and 6.35 mm.
- The Wireless Z Probe is stored in the Automatic Tool Changer where it is charged automatically while not in use. The probe will display a yellow light when it is charging which will turn off when fully charged. The minimum operating voltage is 3.7v, which can be viewed in the tool drop down in the Carvera Controller app. If you use your Carvera once a week, the probe should remain charged enough for typical use.
- To pair a Wireless Probe, it must first be charged as described above. To pair, open the pairing wireless probe window in the Carvera controller and press start pairing. Then Press and hold the button at the end of the probe for about 10 seconds, or until it starts to blink green quickly. When pairing is complete, the green light will blink 5 times slowly. The Carvera will automatically find the wireless probe and pair it to our machine. We can also test the wireless probe by opening the diagnostic window, then pressing the button on the end of the wireless probe. The status light next to probe should illuminate when the probe is being pressed.
- To use the Wireless Probe, enable it when configuring a design to be machined. we can adjust the position of our Z probe which is shown as a red dot in the preview, which should be in the lower left corner of your design by default.

The Tool Setter is shipped with every Carvera CNC and allows for users to set the X, Y, and Z origin positions for their stock. While the Wireless Z probe works to set the z height automatically in most circumstances, you may find that the XYZ tool setter is optimal when working with uniquely shaped stock, stock secured in fixtures, or when a rotation or flip is performed during a project.
- You should raise or remove the dust shoe for the manual probing sequence so that it does not obstruct or interfere with the probing block.
- Select a tool to use for the probing sequence. The default tool is the test rod which ships with the Carvera and is assigned to tool slot 6 in the tool changer.
- Manually move the tool head of the Carvera so it is located over the bottom left corner of your stock.
- Plug the tool setter into the power port on the side of the Carvera bed, and attach the magnet cable to the spindle collet as shown in the tutorial video. Place and square the tool setter block on the bottom left corner of your stock as shown. Adjust the tool head position so that the bit is located above the pocket of the tool setter.
- In the Carvera Controller's Config and Run window, configure the work origin so that it is based on the XYZ Probe. The parameters for the test rod are a height of 9 and diameter of 3.175mm. Adjust if using a different tool. After pressing OK, the Carvera will measure and record the X, Y, and Z position of the tool setter.
- If needed, adjust the offset of your design based on the current position within the Config window to offset the design from the XYZ positions recorded with the tool setter. Auto Leveling and Scan Margin can be used with the XYZ probe, but choosing Auto Z Probe will override the Z height position recorded.
Please note, the interface for the XYZ Probe was changed in the Carvera Controller app version 0.9.6 and later. Obtain the latest version of the Carvera Controller here.

The optional 4th axis allows for users to expand what is possible as the Carvera can rotate stock during machining for more complex geometry and production techniques. You can purchase the 4th axis module from the Makera store and equip it to any Carvera CNC as shown in this guide.
To Attach the Module:
- First, turn off the Carvera and ensure there are no corner clamps on the bed of the Carvera before attaching the 4th axis module. Place two dowel pins in the preset locations on towards the front of the bed
- Plug the 4th Axis into the port on the left-side of the bed, then lower the module onto the bed while aligning it to the two pins. Ensure the cable does not get caught under the module (between the module and the bed)
- Secure the module using six M5*20 screws through the preset holes, then power on the Carvera to reset the machine
- Remove the dust shoe and secure the dust collection hose in place as shown in the tutorial
To Adjust the Chuck:
- The 4th Axis Module comes with two wrenches which can be used to open and close the chuck. Turning the wrenches inwards (towards each other) tightens the chuck, while outwards opens the chuck further.
- The chuck jaws can be installed in two configurations to allow for a wide range of stock sizes to be secured, it is important that the jaws are loaded in the correct order as shown in the how-to video, and this guide.
To Adjust the Tail Stock:
- The Tail Stock can be slid along the 4th axis by loosening the two set screws at its base, you do not need to remove these screws entirely.
- The handle of the Tail Stock can be turned after loosening (but not removing) the set screw at the top of the Tail Stock. This can be pressed into our stock to secure it in place. After positioning the Tail Stock, aways ensure that the set screws are tightened to hold the position during manufacturing
Loading Stock and Running a Job:
- For typical square stock, like the 4th axis relief example project, we recommend drilling a small hole on the center position to make securing the stock easier to do. its also important to rotate the stock so that the corner aligns with the vertical axis as shown in the example
- When a 4th axis file is loaded into the Carvera Controller, the 4th axis will automatically be selecting in the configuration window rather than an Anchor point
- Set the X offset relative to the right edge of the 4th axis head stock, Y offset should be 0
- Scan Margin will trace the edge of your part on the stock before machining using a laser pointer
- Auto Z Probe should be enabled for a fixed position specific to the 4th axis, while Auto Leveling is not used for 4th Axis Machining
- Always power off the Carvera before removing stock from the 4th Axis Module after manufacturing

The Carvera's vacuum system allows for users to not only have a cleaner machining experience, but also a safer one with less maintenance too! It is important to ensure proper setup and maintenance in order for the vacuum system to function properly.
- To adjust the locked height of the dust shoe, pull the plug outwards to unlock and change the locked position. To allow for the shoe to move freely, rotate the plug counter clockwise by 30 degrees. Allowing for free vertical movement is recommended for typical machine operation as this will accommodate a wide range of bit lengths and also allow for use of the automatic tool changer.
- In some circumstances, like when working with metal, using the 4th axis, or laser engraving, the dust shoe should be removed. First raise and lock the dust shoe in the highest position. Then loosen the retaining strew on the body of the dust shoe to remove it from the holding bracket. When removed, the dust pipe can lock into the holding clip at the top of the head. By removing the shoe, the air assist nozzle can be effectively used for chip evacuation or to prevent scorching during laser engraving.
- It is important to empty and maintain the dust bin frequently based on use. The dust bin can be removed from its position at the back of the machine with a gentle tug so that it can be opened and emptied.
- You can also bypass the dust bin and connect your Carvera to an external vacuum or dust collection system. First, switch exit position at the end of the dust collection pipe from the internal channel to the bypass channel. Next, remove the plug and connect your own system to the bypass port on the back of the Carvera machine.

¶ How to Clean and Replace Dust Filters
The Dust Filter is a key component for the Carvera's internal vacuum system, and proper maintenance is key for optimal machine performance. Replacement filters can be ordered from the Makera Store.
To clean and replace the filters:
- Remove the dust bin from your Carvera machine with a gentle tug to release it from its position.
- The filter, which is also the lid of the dust bin, can be removed with a push and pry from the handle side of the bin.
- To clean the filter, we recommend using a shop vac or small brush to clean the underside and to increase air flow.
- These filters should also be replaced after continued use. To install a new filter, first line up the pins on the end of the dust bin, then pivot and press the filter lid into place. This may take a large amount of force to snap the filter in place.

¶ How and When to use Air Assist
Every Carvera is equipped with an Air Assist module which can be used in a number of circumstances. Typically, we would want to enable air assist for the following projects:
- When laser engraving, air assist can reduce scorching or burns on materials like wood and MDF
- When working with metal, air assist can be used for chip evacuation to keep both the material and bit cool
- When working with the 4th axis module, we must remove the dust shoe and the air assist can be used for chip evacuation or to keep the part clean during manufacturing
To use the air assist module:
- First, raise and remove the dust shoe and secure the dust collection hose as shown in the tutorial video
- An air compressor or pump can be connected to the port on the back of the Carvera
- The air pressure can be adjusted by pulling the blue knob outward, then rotating it to increase or decrease flow
- The air assist can be turned on or off from the Diagnostic window in the Carvera controller app

Scan Margin allows for users to have greater success and ease of use when setting up a design to machined. When enabled, Scan Margin will automatically trace the perimeter of our designs using a laser pointer built into the wireless Z probe.
To enable Scan Margin:
- First, load a file in the Carvera Controller App, then press the Config and Run button
- Within the options on the side menu, Scan Margin can be enabled or disabled
- After enabling Scan Margin, we can note that the perimeter of our design will bold when enabled in the preview window
When enabled, the Carvera will trace the perimeter of our job after setting the origin point. The perimeter is displayed using a laser pointer built into the Wireless Z Probe. Scan Margin can allow us to ensure that our design is placed in the correct location for our stock, and that no clamps or obstructions are in the way.

Every Carvera is equipped with a Wireless Z Probe which can be selected automatically using the multi-tool changer. This probe is used to determine the height or thickness of our stock in order to make setting our origin points and preparing are jobs seamless.
However, the Wireless Probe can also be used to automatically level our stock too! Let's say your working with rough stock that doesn't have a flat surface, If you only determine its z height from a single point, then you may get inconsistent machining where the thickness of the stock deviates from the point where the origin was probed. But with Auto Leveling enabled on the Carvera, the wireless probe reads the z height at multiple points, then makes a map of your stock to automatically adjust the z height during machining based on the curvature of your stock.
To enable Auto Leveling:
- First, load a file in the Carvera Controller App, then press the Config and Run button
- Within the options on the side menu, Auto Leveling can be enabled or disabled, and configured
- Within the Configuration window, we can first adjust the Clearance. The Clearance is how much the Z Probe will lift before moving to the next point
- Also within the Configuration window, we can determine how many probing points will be measured for the X and Y axis
The greater the warp or change in z height for your stock, the more clearance you need to prevent the probe from crashing into your stock during probing. And the more points you have, the more accurate this automatic leveling process will be. We also recommend setting the Z Probe origin point to be at the highest point on your stock.

Every Carvera is equipped with a diode laser module that allows for you to cut and engrave a wide range of materials in addition to what is possible using the milling spindle. Paper, cardboard, felt, leather, wood, and other materials are safe to engrave using the laser, and many of these materials can be cut safely as well. Not all materials are safe to use with laser operations however, ensure you check to see if the material you wish to use is compatible with lasers and if not, utilize milling operations instead.
Before using the laser, you need to prepare your Carvera for laser operations. You can also complete projects that use both milling and laser operations, and we typically recommend completing milling operations first. When doing so, make sure the work area is cleaned thoroughly as dust may be a potential fire hazard. Additionally, you should do the following before using the laser:
- Remove the laser protective cover, focus the laser (if needed)
- Remove the dust shoe
- Connect and use the air assist module (not required but recommended)
- Ensure you are in a well ventilated space
- Ensure you are using protective eyewear and or a laser protective cover on the canopy
You can find recommended speed and power settings for a range of materials compatible with the laser module on the Speeds & Feeds page of our wiki site. And to prepare designs for the laser, we recommend you use Makera CAM.

¶ How to Attach and Connect a Tablet
The Carvera comes with an arm to hold your device which can attach to either the left or right side of your machine. We can use phones and tablets to run the Carvera Controller App for a more ergonomic user experience. Tablets can be connected o the Carvera by either using the rear USB-C port or WIFI.
The default position for the arm is the right side of the machine. To install the arm on the right side:
- Align the arm in the mounting pocket on the right side of the Carvera
- Fix the arm in place using the provided machine screws
- The USB port on the right side of the machine can be used to charge your mobile device
The arm can also be installed on the left side of the Carvera, though the steps vary from the default position:
- First, remove the decorative cover plate from the left side pocket which comes installed on the Carvera. This cover plate can the be installed on the right side instead
- Align the arm in the mounting pocket on the left side of the Carvera
- Fix the arm in place using the provided machine screws
- In order to use the left side USB port for charging, we must switch the cables plugged into the Carvera controller board
- Carefully remove the back cover of the panel and swap the USB-R cable with the USB-L cable as shown in the tutorial video

Every Carvera CNC is shipped with a spindle collet for 3.175mm, or 1/8" bits. But you can change the collet to use bits with shank diameters of 3mm, 3.175mm, 4mm, 6mm, and 6.35mm, or 1/4". These collets can be purchased from our store, along with bit collars for each size bit you may choose to use, as well as bit adapters to use different shank diameters in a single project.
To remove a the spindle collet:
- Drop any tool that is loaded in the spindle using the Carvera Controller App
- Remove the dust shoe and dust pipe
- Loosen the collet from the spindle by turning the collet removal tool anti-clockwise
- Finish unscrewing the collet by hand, and expect it to drop from the spindle
To install a spindle collet:
- Insert and screw a collet into the spindle by hand, rotating it clockwise to tighten
- Once hand tightened, use the collet removal tool to snug the collet. Only snug, do not over tighten
- Reinstall dust shoe and dust pipe, load bits
Ensure all bits have collars installed before loading the automatic tool changer, and replace the wireless probe shank with the correct size to correspond to your collet size. Additionally, ensure your speed and feed settings are correct in your CAM software for different size bits.

¶ How to Install and Remove Bit Collars
Every Carvera CNC is equipped with a 6 place automatic tool changer which makes machining complex designs effortless! But in order to install a tool, every bit must have a bit collar. By using a collar installer tool, we can install and uninstall collars safely which is important as bits are sharp! The installer can accommodate bits that are 3mm, 3.175 mm, 4 mm, 6 mm, and 6.35 mm.
To install a bit collar:
- Unscrew the handle of the installer so it extrudes approximately the length of your bit
- Unscrew the cap of the installer tool, remove the thimble and two spacers
- Insert a blank collar into the base of the cap, followed by carefully inserting your bit into the center of the collar
- Insert spacers around the bit to hold it in the center of our installer shaft, use as many spacers as are needed based on bit diameter
- Carefully thread the cap with the collar, bit, and spacers back onto the main part of the installer, and then begin to tighten the handle. Note, this may require a large amount of force.
- When the handle is fully threaded back into the installer, our bit is at the correct depth for our Carvera tool changer. Unscrew the cap and remove the bit to install it into the Carvera
Bit collars are also reusable and can removed from a dull or broken bit. To uninstall a bit collar:
- Unscrew the handle of the installer to provide space for your bit
- Unscrew the cap of the installer tool, remove the two spacers and thimble
- Install the thimble in the handle side of the installer, aligning the closest size of the thimble with the diameter of your bit
- Insert your bit with collar through the cap so the cutting side of the bit is extruding through the opening, then carefully install the cap with bit back onto the installer handle
- Tighten the handle to press the thimble into your bit so it is pressed out of the collar. Remember, even broken bits can be sharp, so be careful!

Printed Circuit Boards, or PCBs, are crucial components in nearly very device and appliance we own. The PCB Fabrication pack provides all of the materials and tools needed to manufacture complex PCBs using the Carvera.
As shown in the LED Light example project, we can make PCBs that are simple or complex by applying a UV solder mask. A solder mask insulates our PCBs which enables us to create more complex and professional quality electronic prototypes.
In addition to PCB blanks and the supplies to apply a UV solder mask, the PCB fabrication pack also includes alignment pins (to make two-sided PCBs), V-bits, corn bits, and drill bits. These supplies allow for a wide range of designs to be manufactured while taking advantage of the Carvera's automatic tool changer and calibration features.
The Carvera CNC is also compatible with a wide range of CAM solutions to create PCBs, including CopperCAM and FlatCAM. But we recommend you use MakeraCAM (coming soon) as it is optimized to prepare Gerber files using the tools included in the PCB Fabrication pack, as well as the built-in laser engraving module.

By applying a UV solder mask to a custom PCB, we can create higher quality and more complex PCBs using the Carvera CNC. Printed Circuit Boards, or PCBs, are crucial components in nearly very device and appliance we own. The PCB Fabrication pack provides all of the materials and tools needed to create PCBs with and without a UV Solder Mask.
To Apply a UV Solder Mask:
- First manufacture the traces onto a PCB blank as shown the LED Light example project
- Do not remove the PCB from the Carvera, but move the tool head to a clearance position
- Apply thin coats of UV solder mask using the roller provided in the PCB fabrication pack. Always wear gloves whenever handling uncured UV solder mask!
- Between coats, use the UV curing lamp to cure each layer of solder mask. Typically curing layers takes approximately 15 minutes, but this time will vary based on how thick each coat is applied
- 2-3 coats usually creates a high quality and durable finish
- Excess UV solder mask can be cleaned off the clamps and roller using alcohol wipes
The Carvera CNC is also compatible with a wide range of CAM solutions to create PCBs, including CopperCAM and FlatCAM. But we recommend you use MakeraCAM (coming soon) as it is optimized to prepare Gerber files using the tools included in the PCB Fabrication pack, as well as the built-in laser engraving module.
