Didn"t find any info in online help about additional axis! (only how to use in g-code, but not how to connect to smc_interpolator ).
Did I miss relevant info/pages in online help?

tried some options and used Q-axis in G-code and found out that you have to use dA2 variable from smc _ Interpolator to connect to smc_ControlAxisByPosition

The axis controled in this way does not finish a task! .
If I use for example Q25 and next step Q0 it will start but not finish the first task, but right away steps to next line .
I can solve it with G4 T.. (time delay )

Do I something wrong here or does it work this way. Did I forget to connect a feedback?
