    Does anyone have an idea how to run such a spiral on CNC smoothly without stops? SMC_SmoothPath and SMC_RoundPath don’t help. In general according to the documentation they should work on arcs but in the example only straight lines are shown and I get the impression these functions only work for straight lines.

    Hi blitz,

    the G1 sentences N50, N70, and N110, which have length 0, lead to a stop of interpolation between the arcs. If you remove these lines, SMC_SmoothPath works (I tried it).

    Bst regards,

    Georg
