Revision Notes:

 

  • 09/01/2024

    • New post variables to support local subprogram call (M97).

      • local_sub_num_call - will output “prefix defined in 658 + sub program number”, like P100

      • local_sub_num_def - will output “N + sub program number”, like N100

      • local_sub_num_no_prefix - will output “sub program number” only, like 100

    • New post variable added to handle G95 output on Okuma controls in Mill Turn jobs.

      • force_feed_mode_upr forces the output of the string that defines Unit Per Revolution feed mode on the machine. The string output is defined on post question 729

    • Haas-specific peck tapping blocks have been added.

      • Block 102 Haas Peck Tapping Cycle - used to output Haas-specific peck tapping cycle.

      • Block 103 Haas Peck Tapping Cycle Point - used to output the details for each pecking point in the Haas peck tapping cycle.

    • Corrected an issue which caused a 5 axis post to output B and C axis at zero for the start of program.

    • Corrected an issue which caused a Y-axis travel limit error when posting a face drilling on a sub spindle from a previous file.

    • Corrected an issue which prevented post question 535 from being applied to the Lathe drilling which caused the feed to be output on every feed line.

    • Corrected an issue which caused a crash when using an invalid value for an edit box in the .customdrill file for the Advanced Posting Page.

 

  • 02/14/2024

    • Corrected an issue which prevented the rotary_xyr_angle and p_rot variables from outputting the proper values.

    • Corrected an issue which caused a system lock up when the comment_start and comment_end variables are used without their respective post blocks, 630 and 631, being defined.

    • Corrected an issue which prevented rpy_angle_xyz_extrinsic_1, 2, and 3, from outputting the proper value when certain UCS/Faces are selected for an indexing system.

    • Corrected an issue which prevented feedrates from being output in a lathe program.

 

  • 09/05/2023
    • Added post questions 58 and 59 to control output of on/off codes based on the next move in LPW jobs.
    • Added post question 560 to allow for output of a helix with multiple revolutions.
      • Added post question 733 and 735 to set the prefix for the total angle, and pitch of the output helix.
    • Added post question 557 to define the r-value in drilling canned cycles. Can now be updated from absolute, to signed and unsigned incremental distance between the rapid plane (initial plane) and the feed plane (reference plane).
    • Added post question 558 to determine whether nested comments are allowed to be output.
      • Added post question 559 to define the replacement string for nested comments.
    • Added new post variable output_note to allow you to include any notes added to the job in the posted output.


  • 09/05/2023
    • Fixed the MDI Post variable name's mistake. The MDI post variable names must begin with the letters "MDI" in capital letters.
    • The typo for Post Block Number 556 (556. Break Arc segments for Posting Modes) has been corrected.
    • Fixed a spelling error in the API name "MILLTURN_GetCAxisDisable()".
    • The spelling of the three variables "euler_angle_yzy_intrinsic_1",  "euler_angle_yzy_intrinsic_2", and "euler_angle_yzy_intrinsic_3" has been fixed.
    • A typo in the API name "MILLTURN_GetFirstPeckDrillIncrement()" has been fixed.

 

  • 09/06/2022
    • Included the description of the usage of the new Post question 556 that controls the breakage of arcs for different posting modes.
    • Added the description of charout_xx Post variable.
    • Updated the description of Post question 228  with an example and its connection to the charout_xx variable. 
    • Added the description of Post question 3529 that defines the Polar coordinate mode for the Mill Turn machines.
    • Updated the Post question 3528 description that this Post question is deprecated.
    • Added the description of Post question 3597 that defines the feedrate value for the Polar coordinate mode 2. 


  • 09/02/2022
    • Updated the description of the Post variable thread_g33_feedrate and added a description of new block 1708.
    • Added the description of the Post Variables thread_chamfer_numofleads and thread_chamfer_distance.
    • Added the descriptions of the Post question 1798 that define the lead value of Thread Chamfer.
    • Added the description of the Post question 1799 that defines the prefix of the Chamfer distance of Lathe thread.
    • Added the description of the Post question 1307, which sets the feedrate mode for the Lathe hole operations(non-tap). 
    • Added the Block 324 that define the maximum DPM feedrate.


  • 08/17/2022 
    • Added notes to the description of Post Block 54 that all the rapid move variables must be in the same line.

 

  • 06/21/2022
    • Added the description of Post question 239 (Output 0 dwell value?).
    • Added the Post questions and blocks related to Multiple coolant codes.
    • Added the description of Post variables that get the initial positions of X, Y & Z coordinates in the different coordinate modes.
