    Need Help with Heidenhain TNC2500B Post for BobCad

    I'm having a bit of a problem with the attached Post for TNC2500B Controller on a Bridgeport 1020X Interact CNC Mill. I had to modify the post to run on my machine. I copy and pasted the FEED = Abs(Round(MILL_GetCannedCycleFeedRate(),1)) from the peck cycle becuse it was missing in the post. The problem is it is post 0 for a feed rate. Do i have something wrong?

    Dim REF
    Dim DEPTH
    Dim PITCH
    Dim REFSTRING
    REF = -Abs(Round(MILL_GetInitialPlaneHeight(), 4))
    DEPTH = -Abs(Round(MILL_GetDrillDepth(),4))
    DWELL = -Abs(Round(MILL_GetDwell(),4))
    FEED = Abs(Round(MILL_GetCannedCycleFeedRate(),1))
    FEED = Int(FEED * 10)
    If REF > 0 Then
    REFSTRING = "+"&REF
    Else
    REFSTRING = REF
    End If
    MILL_ProcessPostLine("'CYCL DEF 2.0 TAPPING'")
    MILL_ProcessPostLine("'CYCL DEF 2.1 SET UP "&REFSTRING&"'")
    MILL_ProcessPostLine("'CYCL DEF 2.2 DEPTH "&DEPTH&"'")
    MILL_ProcessPostLine("'CYCL DEF 2.3 DWELL "&DWELL&"'")
    MILL_ProcessPostLine("'CYCL DEF 2.4 F"&FEED&"'")

    Is that Heidenhain language? I use VisualMill with a TNC2500 (Series 1 Interact), the TNC is set in ISO mode, so takes ISO-formatted POST (programs are a running list of line numbers with g,m, x, y, F, T etc). I didn't know that POST processors would output in "Heidenhain language" (?) (versus ISO).
