Safety Instructions

Our Recommendations

• when milling a material, keep the lid closed
• always think about z heights to not mill into the bed
  • for PCBs and not milling through set it on top
  • for anything else, set it on the
• do not wear headphones so you can heat, if something is not right in the milling process
• DO NOT LET THE MILL ALONE

Makera Safety Instructions

1. Always wear safety goggles when operating Carvera, especially when the protective cover is open.

2. Always wear laser protection goggles when using laser function.

3. Please wear hearing protection when Carvera is machining on the hard materials.

4. Do not put your hands close to the spindle or machining area. Keep the protective cover closed when operating Carvera.

5. Do not leave your Carvera unattended while it is machining.

6. Please be aware of the sharpness of the milling bits during installation, dust collection, and other operations.

7. Milling and laser carving will generate heat. Inappropriate parameters will cause fire hazards. Make sure an extinguisher is in your vicinity.

8. Some materials are harmful to people when machining or laser craving, such as carbon fiber and epoxy resin. Please wear a face mask and turn on the automatic dust collection.

9. Do not expose this machine to rain or wet conditions.

10. Keep children and bystanders away while operating this machine. It requires supervision and the assistance of an adult when children use this machine.

Carvera How to Use

1. Turn On

• Use the Back-Switch to turn on the CNC:

• The Front-Button shows the status of the machine and is used for stand by, but because of the USB Connection, always use the back-button for tuning on and of the machine

2. Connect and Home

You should always home the machine before milling, (even after starting it as a good practice)!

1. To do that, open makera controller:
2. Connect the software via USB on the top left corner:
3. Go to the side panel and press 'HOME':

Side Panel Button on the right	Virtual Controller with 'HOME' in the middle

3. Fasten the Workpiece

Then use the controller to move the bed thowards you and fasten your workpiece:

Type of fastening	Example
Clamps Place the clamps on the bad and tighten the workpiece with them
Tape on a flat workpiece, place some tape on the bottom equally and just stick it onto the bed
Vacuum	TODO
Screws	TODO

4. Zero

Then go to you work origin and use top left buttons to set it individually:

Or use the button 'Set Origin' in the controller on the right:

Auto Z Probe

Finding the Z-zero-point is more special because of the precision needed for it. For this, the Auto Z Probe can be used like this:

0. Make sure, the Auto Z Probe is in the tool changer
1. Place the tool where you want to measure the Zero Point
2. Go to the controller and press 'ZProbe'

In this case we set the origin on the bottom of the workpiece.

Before Milling

It is also possible to probe before the milling (the Check-Box with 'Auto Z Probe'):

5. Upload & Start GCODE

First you need to upload a file to the machine, then select it and then, you can run it.

1. Press the File-Icon on the bottom left (or in the top right hamburger-menu) Then the carvera file-manager popup appears.
2. Then go to your folder/ create a new one for you and go to the top right 'Upload File'
3. Then use the top left to navigate to your file and then use 'Upload&Select' to load the file onto the machine and select it for milling. Or use 'Upload' then 'Close' on the screen and then 'Select' on the correct file in the other screen.
4. There should appear a preview of the GCODE, check the path and choosen tools. Then use the Gear-Icon on the bottom left to start the milling. ALWAYS CHECK THE PATH ON THE BOTTOM!!

Then here deactivate 'Scan Margin' and if allready done 'Auto Z Probe' and press 'RUN'.

Troubleshooting

Carvera Makera

Machine coordinates in the software constantly increase

• just restart the machine, ALSO DISCONNECT THE MACHINE FROM USB and then restart the software

Toolchanger often failes on changeing the tool

• happens because the tools is not correctly inserted and can be solved by bending the metal clamp inwards
