Tip!
See also the example project CNCprepro.pro provided with SoftMotion.
Let us extend the previous example by a path preprocessing function: The corners of the
last program are to be smoothed by splines. This is carried out by the SMC_SmoothPath
block. The CNC program has to be bracketed by the words G51/G50, then the following
results:
If we did not use variables, we could compile the program as Queue in this form and
directly enter it in the interpolator; however, as we are using variables, we have to carry out
the decoding and the smoothing of the corners ourselves. Therefore we define a new block
of type SMC_SmoothPath and call it after the decoder:
