    Question Bobcad error message when posting...

    When i post this error pops up immediately...

    Coordinate transformation matrix does not conform 4x4 requirement.
    Identity matrix will be considered by default.

    ...what is this supposed to mean? and why am i getting this?

    Your machine file is misconfigured or wrong machine is selected per the op

    misconfigured in what way? sorry newbie here trying to track down issues. Can you elaborate? what should I be checking?

    basic setup was done following bobcad support video

    ok, so to address it properly, we need 3 things. Your bbcd file with the toolpath in it, the post processor and the machine files. You can zip those and attach them here.

    I think i remember it could also be a multi axis path on a 3 axis machine without the 3 axis flag set, or vise versa. But if you can attach the 3 items can save a lot of discovery time.

    the matrix is basically the layout of the machine components. There are some specific requirements.

    Hi,

    attached are the files.
    Thanks for your help.
    All of this new to me and what may seem like second nature to someone in industry is a total unknown to a hobbyist user such as myself. Learning the hard way.

    Yeah, the machine definition looks like it is not correct.

    Attachment 296868

    The workpiece transform has no added components, and I'm not sure about having all axis staked on one holder transform like that....

    There needs to be some discussion about how your actual machine moves it's parts. You also left out the machine file to work on. You can find that here:

    C:\BobCAD-CAM Data\BobCAD-CAM V27\MachSim (Blue depends on version using... Please state that)

    Find the folder named like the machine and zip it and attach it here....

    hmmm...yah watching that video again, it looks like you're right.

    I'll need to work through that video again tonight and try setting everything up again.

    Eventually down the road I would like to add a 4th axis to it as well.

    So I watched a bit of the BobCad video you linked to. It looks like a router has the 3 axis stacked, so that's ok. Your holder transform has no name, which falls under the ID element in the definition (That's the thing just above the tool.)

    Then look at your workpiece transform... It's missing any elements added. Right click it and add workpiece, toolpath, stock, initial stock and fixture elements.

    It looks like you have one there, it's just not set up or tied to anything.

    When you click on each of those elements for axis etc, be sure to look at the travels and also the integer matrix. Positive and negative values determine the direction of the movement.... The machine file is for the sim, but also affects the posting engine and how it posts code out for the machine.

    Re: Bobcad error message when posting...

    yah i added one in but not sure how its supposed to be tied into the machine, i assumed i would just add to base of the machine since it would be sitting on that.

    I'll have to go through all of the bobcad help files again, other than that video i would have been totally lost as to what to do. No idea if that 4th axis is set up right or not.

    will have to go through all of this again.
    thx

    I think you would setup the workpiece transform "under the Rotational" as it would now be holding the workpiece...

    So the actual "table, stock and rotary" wont move with any of the x,y,z axis moves. Those all happen as a separate group. With the rotary element sitting there by itself on the table, the workpiece goes into it......

    Setting the limits, travels, and initial start location of all the particular elements will follow.

    right...will setup a 3 axis file first since i don't have the 4th for my machine yet, but will need to set up a 4th axis definition as well.

    okay, did the setup fresh again. No post errors popping up now.

    will need to figure out the 4axis setup as well....will start a new thread for that.

    also i have 4axis standard version so i guess full machine sim is not supported so don't have to worry about setting up stl files to represent my machine.

    thanks
