  1. Just to add to  this; laser iInterferometry has been used to provide feedback for more accurate (dead accurate) motion. We have a customer that incorporated this on a waterjet trimming application using a robot and it saved the day.

  2. On a lathe i would just add a U command equal to the taper error. Run part with offset in X (so you don't scrap the first piece). Measure part for taper error. Look in code for the line with the G01 Z-where ever and put the U on that line.

    Eg;

    G01 Z-1.3125 U.002

    The U will move the X axis incrementally that value over the length of the Z move. I would try to figure out where the problem is. Poor set up (to much stick out comes to mind), need center support, or previous crash causes taper at all times. IMHO best to fix the problem than to try and work around.

  3. The example shown only has G76 canned cycles (these do not require or use the P and Q block numbers)

    The error  "936 option not found" has the answer to your problem; read as option not purchased.

    Some of those older Mazak lathes wont even read G Code, BTW you get the same error on those.

  4. The insert.tbl error is due to an incorrect data path.

    Likely your shared folder location has been set incorrectly in the configuration file.

    An easy fix is to delete your .config file from your "My Mcam 2018" folder.

    Restart Mastercam and the error will go away; you will need to reset your custom configuration changes.

    Do not open the system config with an open .mcam file. Always do a file new before entering the configuration menu.

     

     

  5. The easiest way would be to path to you desired network drive during install

    for an existing set of user drives you can change it manually in System Config/Files

    then change the data path for "Shared Data Folder"

     

    Good idea...but Mastercam will not allow a non local drive to be specified during install; it just wont.....

     

    Yes, that will move the files but will not update your config file which is necessary for the setup to work properly

    This is where the user will be prompted to copy all the local shared folder to the network.....

     

     

     

    The setting is actually controlled in the registry:

     

    The main setting that will affect all users that log in to the computer and launch Mastercam for the first time will have there shared folder in the config set to: 

     

    HKEY_LOCAL_MACHINE\SOFTWARE\CNC Software, Inc.\Mastercam 2017...shared folder

     

    If the user has already launched Mastercam once then the configuration path needs to be changed as shown above.. It should also be changed in:

     

    HKEY_LOCAL_MACHINE\SOFTWARE\CNC Software, Inc.\Mastercam 2017

     

    AND

     

    HKEY_CURRENT_USER\SOFTWARE\CNC Software, Inc.\Mastercam 2017

     

    Wish it were more straight forward but this is how it is....

  6. In your pretract post block, you should see the output for M05

     

          pbld, n$, sccomp, scoolant, psub_end_mny, e$
          pbld, n$, *sg90, sg49, "Z0.", "M05", e$
     
    You will want to add logic so that if the current t$ is your saw then it would output the commands you are looking for.
     
         if t$ = 15, [
          pbld, n$, "M03","S1000", "(SLOW DOWN THE SPINDLE)" e$
          pbld, n$, "G04", "P10", e$
          ]
          pbld, n$, sccomp, scoolant, psub_end_mny, e$
          pbld, n$, *sg90, sg49, "Z0.", "M05", e$

     

    My logic is showing that if Tool #15 was the tool you wanted to slow down before stopping, it would output it.

    To make the logic easier to use picking a specific tool is the easiest way; there are other methods as well.

     

     

    The output you show appears to be 5axis; so your post provider can add this logic for you.

          pbld, n$, *sg90, sg49, "Z0.", "M05", e$

     

    The real issue here is that the VFD (Variable Frequency Drive) parameters are a bit messed up.

    You can program the parameters of the VFD so that the spindle stops dead on an M05.

    The machine builder likely has this set conservative to prolong spindle motor life.

  8. "Correct me if I am wrong but Isn't this location handled under system configuration/ files/data paths"

     

    That system config setting only comes into affect when creating a control definition from scratch.

    In V9 and previous it was the actual setting to make the change.

     

    The post could also have a question and logic in place to direct the output to the correct location.

  9. The issue was that the shared folder was changed in the config...it is set during install...to the default path c:\users\public\documents\shared mcam2017\

    The shared folder path is stored in the registry in HKLM and HKCU

    in the config it is set to a variable <shared data> IIRC

    When the path gets hosed up, it gets set to c:\program files\mcam2017 and it will generate that error.
