    Can you post a snippit of the offending g-code?

    In my sample, it moves to the first hole position then drops to feed height, drills, and then retracts to feed height between the subsequent holes. It is what I'd expect. I attached my settings. Also, be aware, you must select the hole faces geometry to use the hole bottom definition. When using points as geometry you must define the depth, otherwise it will assume the point as the depth, which is null or zero.

    I can tomorrow.

    Look at the code after a tool change in the middle of the program. That is where it happens.

    I added a few more operations and tool changes but I don't readily see the issue. I'm running Fusion 360 2.0.3803. What version are you running? I sent you a PM.

    It only seems to happen when a canned cycle is involved on one of the set ups. The other setups seem to work fine.

    Forhire I emailed you the Fusion file. I'm running 2.0.3803

    After looking at the code changes Autodesk made to the 2-16-18 release I decided to pass this back to them for review. The release "Updated work plane handling for posts." and the code has me stumped. It's robotics season and I'm short on brain power and sleep.

    Bob at Autodesk sent me the fix today and said:
    The retract logic was redesigned and since this post does not physically retract the Z-axis at a tool change, the post sees that the current Z-axis is higher than the previous output Z-axis and so thinks it is retracting the tool.
    I've uploaded a new version to my posts folder. He said the change will be released soon on their repository.

    The change requires one change on line 457 add: retracted = true;
    if (insertToolCall) {
    forceWorkPlane();

    retracted = true;
    setCoolant(COOLANT_OFF);

    if (properties.useToolChanger) {
    if (!isFirstSection() && properties.optionalStop) {
    onCommand(COMMAND_OPTIONAL_STOP);
    }
    }
    It makes sense being that the DX-32 doesn't require a G28/G53 retraction to tool change position prior to change.

    Looks like a good fix. I will be using it tomorrow, hopefully no more surprises.

    Is it possible for this post to Output a tool change location? I'm currently running tall parts and I need to move the table out of the way for Tool changes. Currently I am hand editing every time I post it. I hope I don't forget one.

    There are likely a few ways to approach this, but likely the best way is to set your CLR POINT (Option 5 on SETUP menu) on the machine and then use M26 to tool changes instead of M6. This will allow the operator to choose a verifiable location rather than an estimate in CAM.

    M6 Tool Change (Non-Modal)
    M26 Tool Change, Goto Clear Pt (Non-Modal)

    M20, M21, M22, M26 — Move To Clear Point
    These commands are similar to M0, M1, M2, M6 respectively except the X and/or Y axes automatically move to the
    clear point and the Z-axis returns to the home position. The clear point is set by the operator in SETUP such that the
    part or fixture is cleared and the tool can be easily removed. In moving to the clear point first, the quill retracts, then XY
    motion occurs.
    NOTE
    The system must be in the Rapid Traverse mode (G0) when Move To Clear Point occurs. No X, Y or Z data should be
    programmed with a Move To Clear Point M-code.
    Example: N230G0T3M26; Tool Change at Clear Point
    I'm running tall parts/fixtures right now and this is something that definitely needs to be sorted. I really wish I could reverse the homing routine so it doesn't travel under the carousel. Nothing like ripping long tools out first thing in the morning.

    I think using the clear point is the best solution but I'm open you your thoughts before I change the post.

    The M26 method sounds good to me. Can it be an option, M6 or M26?

    After the M26 tool change the tool needs to go Z+ so it will clear the part/fixture. I have. had some close calls by not doing this.

    This is how I have been doing my tool changes. Angle plate is setup on right side of table.

    G0X-8. ;move to clear area
    T4M6
    Z2. ;moves tool above part this could come from the clearance height of the next operation
    XxxxYyyyy
    Zzzz


    Other CAM programs give you a choice for X/Y tool change location. Typically on this machine it will just be an - X move. Not to hard to figure out where it is. And it still leaves the clear point for parking the table at the end of the program.

    Either way would work the me. It would be so nice not to have to manually edit every time this is needed.

    Yes. It retracts the spindle and then performs the XY move.

    I added a variable called useM26 which will swap M6 for M26. It is off by default. I applied this change to the 5/1/18 bridgeport dx32 post from Autodesk. This is newer than what I've been running. Let me know how you like the option and I'll upstream it if it's good.

    This is what the output looks like with M26 turned on.

    N1 ;(2D Contour1 3)
    M9
    G0T8 M26
    S4500 M3
    G54
    M8
    G17
    G0 X-6.7625 Y-0.075


    After the tool change the table positions to the new XY location with the z at the tool change height. This can cause a crash because the tool has not been brought up to the clearance plane. In the part I am doing the tool hangs below the part at the tool change height.

    I do not know how difficult it would be to do the M25 in the post.
    Thanks for all your help with the post.

    Good catch. I fixed the post and uploaded it to the posts directory.

    The edit simply involved adding the bold text after line 473.

    if (properties.useM26) {
    writeBlock("G0T" + toolFormat.format(tool.number), mFormat.format(26));
    writeBlock(mFormat.format(25));
    } else {
    writeBlock("T" + toolFormat.format(tool.number), mFormat.format(6));
    }
    I want to know who the genius was who thought it was ok to change tools below the full retract height. Makes me want lift the mechanism up.

    Has anyone had luck using the Multiple WCS Offsets with this post. I have tried every thing to get it to post multiple offsets with the check box shown in the picture.

    I am currently making a duplicate setup and posting both setups. This is cumbersome when it comes to making adjustments.

    The increment should be 1. The duplicates is the total number of WCS offsets. You start with G54 and then G55.

    Here is an example that uses G54 thru G59.

    Don't confuse WCS offsets with an array.

    Yes I did. Basically it just duplicates the code with an incremented WCS. Your offset increment of 5 definitely wouldn't work, it must be 1 (ie, G54+1 is G55, and etc.).

    I have attached a zip file with a simple test file and the resulting g-code. I haven't back plotted it but it looks fine. I've used multiple offsets in the past. I'm currently running 2.0.4116.

    Also, be certain your not confusing WCS duplicates with a pattern (array) which is simply replicated from your original based on direction and distance.

    Soon as I get back to it I will try it again. I tried it with several different numbers in the WCS field.

    I'm also interested in the pattern that you did. I guess I have not seen that button yet. I will need to learn how to do that shortly.

    Click Setup, New Pattern. Then create or move your paths under the pattern and they will be replicated as an array pattern.
