Instruction Manual

Note: The air assist module and the dust collection module cannot work at the same time, so
remove the dust shoe and turn off the automatic dust collection before using the air assist
module. When the air assist module is not used for a long time, please turn off the air pump. Be
careful that the air nozzle does not interfere with the dust shoe and auto tool changer mechanism.
Air Assist Module
Use case: There are two main use cases for the air assist module. One is for chip removal and cooling
during CNC machining, especially when machining metal materials. The second is to prevent the
material from burning during laser engraving to improve the engraving quality.
Installation: An normal small air pump is more than enough for the Carvera air assist module, insert the
8 mm pipe into the plug at the back of the machine, and ensure that the air pipe is firmly fixed.
Air control:
1. Use GCode commands M7 and M9 to control the opening and closing of the main air switch.
2. Adjust the blue knob at the end of the air assist module to control the airflow, pull the knob to adjust,
and press the blue knob to lock. Turn the knob clockwise to decrease the flow and counterclockwise to
increase the flow.
3. The angle of the air nozzle can be adjusted to match different tool lengths and laser focus position.
Note: The top clamp is not very thick, so please do not screw too tight.
Note: If you need to cut through a workpiece, we highly recommend placing a 1-2mm thick waste
board (as the complimentary one) under the workpiece. This can avoid damage to the workbench.
Note: Please select corresponding length screws to fix different workpieces, you do not want
to scratch the plate under workbench.
Workholding Tools
Workholding is one of the most important steps when using a CNC machine. Carvera provides two
different workholding methods and corresponding tools to adapt to different types, shapes, sizes of
workpieces. While holding the workpiece, you can also locate the workpiece to the pre-defined posi-
tion accurately by using Carvera’s anchor based system.
1. L-Brackets: Carvera provides two types of L-shaped brackets, a thin one and a thick one, as shown
in the figure. The L-Bracket can be fixed at one of the two anchor points with two 4mm dowel pins
and three M5 screws(thick bracket uses long screws). The lower left corner is anchor 1, and the middle
position is anchor 2. There are two semi-circular openings of the thin positioner, you can put two M5
screws to fix the lower-left corner of the workpiece there.
2. Top Clamps: The top clamp usually fixes the workpiece with a thickness of less than 2 cm together
with the thin L-Bracket.The purpose of the top clamp with a cross groove is to facilitate the use of
long sides to fix the workpiece. We recommend using shims at the end of top clamps to fix workpieces
greater than 1 cm.
3. Side Clamps: The side clamp is usually work with the thick L-Bracket together to fix the workpiece
with a thickness greater than 2 cm. The side clamp can also be used with the top clamp to fix a thin
workpiece to process the surface, as shown in the figure.
