    Feedrate Setting In Post

    This pertains to lathe. The generic post works great for me except when threading. It posts out an "E" instead of an "F". Once I edit to F everything runs good. It only puts the E when threading. All other operations use an F. So where in the post can I change to get the F I need?

    it easy to do .
    open the post -> goto here

    force_wcs : yes$ #Force WCS output at every toolchange?
    progname$ : 1 #Use uppercase for program name
    css_start_rpm : yes$ #Do direct RPM spindle start prior to CSS?
    css_end_rpm : yes$ #Do direct RPM spindle prior to Retract?
    prog_stop : 1 #Program stop at toolchange: 0=None, 1=M01, 2 = M00
    tool_info : 3 #Output tool information?
    #0 = Off - Do not output any tool comments or tool table
    #1 = Tool comments only
    #2 = Tool table only
    #3 = Tool comments and tool table
    use_pitch : 0 #0 = Use feed for tapping (force Feed/Min), 1 = Use pitch for tapping (force Feed/Rev)
    rigid_tap : 1 #0 = Floating tap output
    #1 = Rigid tap output (Set parameter 5200 bit 0 to 1 for rigid)
    #(Set M code for rigid tap in parameter 5210)
    tap_feed : 1 #0 = 2/1 (in/mm) decimal places, 1 = 4/3 (in/mm) decimal places
    thread_address :1 #Thread pitch address for lathe threading, 0 = Use F, 1 = Use E

    change number 1 to 0 at red color, you will got F instead of E .
    hope it will help .

    This is the General Settings Info....no mention of feed rate there. I have looked for the thread addres info. Couldn't find that. Has to be in the post somewhere I just can't figure out where. I checked the G76 section. couldn't see anything having to do with feedrate.

    Solved: Change Feedrate from E to F

    I did a search for E and F and found this. I noticed the stre and strf callouts

    # ---------------------------------------------------
    #String and string selector definitions for NC output
    # ---------------------------------------------------
    #Address string definitions
    stra "A" #String for address A
    strd "D" #String for address D
    stre "E" #String for address E
    strf "F" #String for address F
    stri "I" #String for address I
    strk "K" #String for address K

    Then I searched for stre and found this....

    #Format feedrate for lathe thread
    result = nwadrs(stre, feed)
    result = newfs (19, feed)

    When I changed the stre to strf I got the F for feedrate in the posted out program. What a hassle.
