3.3.2 Sweep/Scanning parameters

X Start Speed, Y Start Speed: the scanning start speed, there is no need to accelerate from

0 in the use of stepper motor dragging, but can start working directly from a speed to shorten the

overall processing time, but the speed cannot be too high, because the X, Y axial load is different,

generally the initial speed of X-axis is slightly higher than the initial speed of Y-axis.

X Acc, Y Acc: match with the scanning speed (the layer speed in the layer parameters), if set

too small, the scan speed to be a longer distance, will influence the scanning efficiency. The

machine can be set according to the actual structure and load conditions. For X, Y axis load is

different; generally the acceleration of the X-axis is much higher than Y-axis.

Line shift speed of scanning: this parameter is specially used to control the max. speed of

the scanning to shift vertically from one line to the next below line. If during the scanning, the line

space is too large or the block space is too large when scanning block, and should precisely

positioning for each line or block, you can set the line shirt speed of scanning to a lower value.

This parameter cannot be less than the jump-off speed of the corresponding axis during the line

shift and cannot be higher than the max. speed of the corresponding axis during the line shift, if

the setting is illegal, the controller will automatically set this parameter within the range above.

Scan mode: There are two modes for your selection: general mode and special mode, in general

mode, there is no any treatment during the scan, in special mode, light spots will be treated. If the

special mode is activated, the power of the laser should be increased and correspondingly, the light

spot percentage will be lower and the laser power attenuation will be higher, to achieve the same

depth of scanning, the laser power should be higher. The purpose to select the special mode is to

make the laser to emit beams at high power and in short period, during deep scanning, the effect of

flat bottom can be achieved, however, if the light spots are improperly adjusted, this effect may

not be achieved and the working mode of high power and short period may influence the service

life of the laser. The default mode is the general mode.

Facula/Spot Size: When in general scanning, the parameter is invalid; when in special mode, the

parameter is valid. Controller will keep the parameter from 50% to 99% .
