Attention: at the time engraving, prevent the hand from getting too close to the cutter with
highly revolving speed, and do not observe it in close distance. After finishing the
engraving, first turn down the revolving speed of the principal axis to the minimum; then
rise Z axis in Mach3 through manual control, and move the spindle motor outside the
engraving materials; and then turn off the power switch. Each time after finishing
engraving, the scraps generated by engraving should be cleared in time.
Summary
: You have finished a whole process of engraving practice through this example.
Whatever you engrave in the future, it is of the same operation procedure as this. The key
points are as follows:
①
leave certain margin when clamping materials, so as to avoid the cutter from touching
screws;
②
remember to reset the triaxial coordinates after tool setting;
③
remember to adjust the speed adjustment button of the principal axis to the zero position
in anticlockwise direction.

Install auxiliary operating platform for your engraving machine
●
What is auxiliary operating platform?
Auxiliary operating platform is a board installed on the original operating platform of the machine, and it
can replace the original operating platform;
●
Why it is necessary to install an auxiliary operating platform?
In order to not damage the original operating platform when doing cutting operation; We usually cut
some boards with the engraving machine, but if without the auxiliary operating platform, it may cut the
operating platform in the process of cutting the board, thus permanently damaging the operating
platform. Therefore, we need an auxiliary platform, which is also called backing plate. In this way, we
can cut the board and not damage to the original operating platform of the machine.
It is very easy to install the auxiliary operating platform, and it only needs to fix a soft board (e.g. PVC,
PMMA, or wood board) on the original operating platform of the machine. Then, make an engraving file
and let engraving machine mill the auxiliary operating platform, with the purpose of obtaining higher
evenness. It is also the most efficient method to engrave double color plate, PCB or other materials that
ask for higher demand of flatness.
As shown in the picture: first, clam a PVC board with the thickness of 10mm on the original operating
platform of the machine, then mill a plane, and obtain an auxiliary operating platform with high flatness
at last. If the object you engrave is usually not large, then you only need to install it on the latter part of
the machine, so that it can be applied for a long time and no need to be disassembled.
