Edge banding for several movement blocks (Method 2)

Often a contour is described by a lot of short NC-blocks (e.g. created by CAD-system). For such kind of contours during edge banding it is difficult to localize exactly the cut of the veneer strip at a NC-block boundary.

G108 also activates edge banding and has a modal effect. A special parameter in the channel parameters list [1]-28 offers the possibility to execute the cut of the veneer several movement blocks after the M-function. The M-function itself is executed at once, but the measuring signal is given later. After the measuring signal has been detected, the system continues moving by the specified residual path [1]-2 via several NC-blocks. G107 indicates explicitly the end of measuring. Until that point in time the measuring signal must be detected.

Programming example

N05 X0 Y0 
N10 G108 (Activate edge banding) 
N20 G01 X90 Y90 F20 
N30 M97 G01 X100 Y100 F8 (M97 is of MNE_SNS type, start measuring) 
N40 X110 Y110 
N50 X120 Y120 
N60 X130 Y130 
N70 X140 Y140 
N80 X150 Y150 (<- last block of measuring!) 
N90 G107 (End of measuring for edge banding) 
N80 G00 X200 Y200 
M30 

The measuring process is also possible in the same movement block. But in this case method 1 offers a programming in an easier way.
