TrueMill operations can now change spindle speed between the Rough cut and the Finish Walls cut.
Question: I created a TrueMill operation and I set it to Rough and then Finish Walls on the Rough/Finish page:
I set different Spindle Speed and Feed Rate for the rough and finish cut on the Common to page:
When I post this TrueMill operation, the feed rate, F, changes at the appropriate place for the finish cut, but the spindle speed, S, does not. How do I output the spindle speed change?
Answer: The standard post processors are set up to output spindle speed change only when the tool changes. In this TrueMill toolpath the spindle speed change occurs while the same tool cuts. To output this speed change, add an Upon [Speed] sequence to the post. The added sequence should be similar to the following.
Upon [Speed]
M[Direct] S[Speed]
End
Add the sequence anywhere in the post processor, but outside of existing sequences.
