    TNGv2 Deep Drilling

    I just ran some gcode to drill a deep hole using peck drilling, but instead it just plunged straight to the bottom of the hole (no pecking). It simulates fine in my CAM software. Here is the script I used:

    Code:
    (1001)
    (T1  D=4. CR=0. TAPER=118DEG - ZMIN=-18. - DRILL)
    G90 G94 G91.1 G40 G49 G17
    G21
    
    
    (DRILL2)
    M5
    M9
    T1 M6
    S4850 M3
    G54
    G0 A0.
    M900
    G0 X0. Y0.
    G43 Z20. H1
    Z15.
    G98 G83 X0. Y0. Z-18. R5. Q2. F485.
    G80
    Z20.

    Drill Pecking (G73, G83) and pocket milling (G12, G13) are just partially completed and are still on TODO list in ChangeLog.txt

    Thanks, I read this a while ago and slapped myself for not reading the TODO.

    Is there a timeframe for the peck drilling? That is the only thing stopping me from actually switching to TNGv2, all the other improvements make it worth switching.

    Peck drilling G73 and G83) is implemented and should be released tomorrow.
    (Assuming there will be new version tomorrow because I'm still struggling with some context restore issues.)
