59 FSCUT2000C laser cutting control system User Manual
6.2 Pulse equivalent setting
The system defines that pulse equivalent is the command pulse count sent after
1mm movement.
The maximum pulse frequency of BMC1204 motion control card is 3Mpps.
Assume the maximum operating speed designed by the system is 1000mm / s. Then
the pulse equivalent for each axis should not exceed 3Mpps / 1000 = 3000 Pulse /
mm.
Under the permitted circumstances, we suggest set the pulse equivalent in 1000
~ 2000 Pulse corresponding to per 1mm, and thus pulse sequence can be more
continuous. Please try not to set the pulse equivalent as 200Pulse / mm or less.
Set pulse equivalent of X axis and Y axis as the same as possible, which is
helpful to reduce truncation error calculated by the system.
6.3 Graphics processing is quite slow or pause
In Cypcut, we use node mode to observe this graphic. If nodes are too many and
graphics consist of many micro-segments, please perform curve smoothing on
graphics and then process them.
Check whether the unreasonable delay is set or not, or the unit is misread, for
example, set 200ms as 200s.
If the Z-axis has pause during the movement of lifting and descending, please
check the program version of BCS100 height controller. If It’s BCS100 V2.0
height controller, please make sure the program was upgraded to the version of
V802 or later.
Opening laser after blowing for a long time, please check the serial
communication of laser is available.
6.4 Corner burning
If machine allows, improve FIR frequency and reduce time of acceleration and
deceleration.
Properly increase turning precise parameters, and make high-speed smooth
transition in sharp corner with Bezier curve.
Modify the mapping way, processing the circle overcut by the example as shown
below.
Modify power curve, turn down laser power when speed declines.
Add cooling points on the corner, further processing after blow to cool for a
period with light off.
