    Yeah, the lack a viable posts kept me away for a long time also. I haven't run a lot of parts using this post but so far it has been good. I still have two more machines to sort.

    I uploaded new versions of all my posts tonight. They now include a user option called writeDetails which allows you to toggle the inclusion of the file details in the top of the file. It is on by default.

    Thanks for all the work Forhire and thanks Jim for your input as well,

    The biggest problem I have found with this machine is the lack of being able find exactly how certain codes should be used. For instance, I can't replicate the G8/G9 issue on my TC-1 and there is very little mention of it's use in the manual. In my case it's as if G9 is the default power on setting. Any time I've tried a G8, it hasn't been with good results (very jerky movement).

    What version is your DX32 software Jim? I have both 6.89.57 and 6.89.60...but can't really notice a difference between them.

    As far as G12/G13, when I first got the machine I attempted to run standard Fanuc style G2/G3 helix's. I thought all was good as well, but at the bottom of the helix, when the cutter would transition from XYZ to XY moves, the head would just drop about .01-.015". Not healthy on cutters or parts.

    I remember asking Bart at EMI about this and he said there was a software glitch that was never fixed and using G12/G13 was what I needed to do.

    At that time, I finally gave up on the helical entry and just predrilled a hole (just needed to get the jobs out, no time for experiementing at that point).

    With Bobcad, there was no way to post seperate code for helical....possibly with scripting, but do not know how to do that. A few months ago I gave it another shot but decided why not just have Bobcad output G12/G13 for everything (no G2/G3 at all)....it worked! So my bobcad post outputs G12 and G13 for standard XY arcs with no issue using absolute arc centers.

    I will give your latest post revision a test as quick as a I can. For some reason, I'm not getting e-mailed when there are updates to this thread and didn't realize how many responses there had been since my last visit.

    Thanks again!

    G9 is the default. I didn't see any difference on my TC3 either. Doesn't the TC22 use different axis drivers?

    Interesting. I'll have to test it more carefully. The code can be easily changed on line 958-959.

    // gMotionModal.format((isHelical() ? 10 : 0) + (clockwise ? 2 : 3)), // Use G12/G13
    gMotionModal.format(clockwise ? 2 : 3),

    jgwentworth96 in another thread mentioned the canned drilling and tapping cycles are not retracting properly. Took a quick look at the tapping and sure enough...

    Z0.2
    M29
    G84 X0. Y0. Z0.5 F15.63
    M28
    G80

    Looking at the manual it is clear the Z value must include the clearance plus the thread depth. So taking jgwentworth96 suggestion I changed the post as getCommonCycle(x, y, cycle.depth + cycle.retract).

    Z0.2
    M29
    G84 X0. Y0. Z0.7 F15.63
    M28
    G80

    I compared the corrected post to my Visualmill post and it's correct. I don't use Fusion 360 very much at work so I didn't catch this one.

    I'll dig though the drilling ops... I suspect a similar issues.

    I changed the drilling operations to fully retract. As suspected they all were wrong.

    I did not see any ability for chip break tapping. According to the manual it doesn't appear to be supported.

    I won't have a chance to fully test for a few days so look at your posted code and make sure it looks correct.

    Rod emailed me about an issue related to G3 I and J missing at the end of some circes. Turns out you have to force the value.

    The post has been updated:

    http://home.lewiscounty.com/~forhire...eport_dx32.cps

    The solution was provided by Autodesk here:
    https://forums.autodesk.com/t5/hsm-p...g/td-p/7665881

    Original code:
    // circular output
    var iOutput = createVariable({prefix:"I"}, xyzFormat);
    var jOutput = createVariable({prefix:"J"}, xyzFormat);
    var kOutput = createVariable({prefix:"K"}, xyzFormat);

    Should be this:
    // circular output
    var iOutput = createVariable({prefix:"I", force:true}, xyzFormat);
    var jOutput = createVariable({prefix:"J", force:true}, xyzFormat);
    var kOutput = createVariable({prefix:"K", force:true}, xyzFormat);

    Is it possible to make tapping out like this also? Could we choose. I just prefer using F=pitch. Currently the post outputs F=IPM. So if you change RPM you also have to change feed rate.

    This has been on my todo list for a while. I too prefer pitch feed as my other machines are all Fanuc. I just uploaded a new post file with feed=pitch as default. It can be toggled using usePitchForTapping. http://home.lewiscounty.com/~forhire...eport_dx32.cps

    usePitchForTapping: true, // G95 = Feed per spindle revolution (pitch) mode (FANUC mode).

    Another user recommended changing the drill retraction code. After messing with the default code it became clear it worked if you clearly defined a depth but if you used hole bottom it wouldn't work. I updated all the drill/tapping/reaming operations.

    This is the updated code.
    getCommonCycle(x, y, (cycle.bottom*-1+cycle.clearance))

    Well isn't that nasty. I've been in communication with Bob at Autodesk and they have been following this thread in preparation of a new generic DX-32 post. He sent me the latest post to try. It slots properly and has all of the updates. I looked at my version and couldn't quickly identify the slotting issue. Please test Bob's latest and let me know how it goes. It should also be noted that it appears to be derived from a much more modern source.

    Autodesk has released the official Bridgeport-DX-32 generic post processor that is based off the changes made in this thread. After some review it appears to be based off a more modern code base. The slotting works. They also modernized the drilling operations. Moving forward I will be tweaking this version as needed. http://cam.autodesk.com/posts/downlo...dgeport%20dx32

    I guess I need to start using the new one then. I am having issues with drilling depths on the other one.

    The drill depth issue appears to be related to how hole depths are being selected in Fusion 360 CAM. The new version has a re-written depth routine. If it also is posting incorrectly please upload your model (*.F3D) and I'll take a look.

    When I was messing around with the routine I did have a version that was broken if you use hole bottom as your depth. The deprecated version is the last version I modified and should work either way. Check the MD5SUM on your version. As you can see the Autodesk version is a bit larger.

    It seems that the Hole Depths are working. I will start using the new post from here forward. Hopefully there are not any surprises.

    Thanks for the work you have put into this post Forhire and the others that gave you feedback to make it better.
