    Working Board? Accurate CNC 560 

    Though its got some funky routing :)  and i didn’t quite drill all the way through, this board seems to be right.


    A360_Test 011_small


    I redesigned it a bit and recut it, a small error in one of the rubout tool changes. The main thing i wanted to get rid of was the trace in the middle left, that cuts through an 0603 package, though on the new one one of the transistors traces is going back under itself. I also scanned this one at  2400DPI, seemed to work better..

      Hi. How do you remove the material that is not need it? I can do the isolation routing in my pcb but i also want to remove the copper that is not in use and takes a lot of space like you did in the above pictures

        end mill of increasing sizes and just remove the parts not wanted.

          How are you setting the routing depth?
          I am working with an AccurateCNC 366 and after homing in the z-axis directly over the working area, the bits are still routing way too deep. Almost all the way through the board, completely through in some areas.
          Also, how are you securing the working material? Right now, I am using double sided tape behind the working area and taping the edges of the working material down.

          use the pcb on the wire to set the base Z depth, then in accuratecnc pick the tool you’re using, it’ll tell you the depth it wants to cut at in the little graphic showing the tool profile. then set the depth with the fine adjustment tool on the Z head, remembering there is some backlash so i tend to go over a few clicks then bring it back

          then use the camera to do the test cut and then the size of the cross it cut should show you the cut size. the pcb should be flat, its a floating head so it’ll handle changes, but best to be sure.

          i use double sided tape , not carpet tape since the threads get caught up, and clear tape around the edges of the pcb, so long as the head dooesn’t have to ride on it.

    First double sided board and first router cut 

    I’ll post more details on this, but it looks like a great success.


    The routing of the circuit isn’t yet complete, its just a quick 10mil auto trace in eagle.

    NinjaBadge take #3 drilled, and realisation, AccurateCNC 


    So this came out pretty good, there are still a few traces connected that ought not to be, the drills are slightly off to the right, and didn’t realise it was a double sided board!  whoops ( single sided pcb material)

    A360_Test 008


    But I’m happy with the progress. This is a fairly complex board with some small traces and it had some DRV’s so its not unexpected that it failed in some parts, and i did run it through twice.


    Changing the drill bits isn’t that hard, and I still dislike imperial, the software shows things in inches, and not mil’s or cm and not mm’s, the drill bits are marked in mils, so just shift it left so not a big deal, its just annoying switching back and forth, I didn’t realise AccurateCNC offered a metric version, wish I’d realised beforehand, though its just really the micrometer.

    The Z axis/depth setting for the bit seems to be sticking a little bit, so I have to watch that when I’m setting a depth.


    For drilling depth, I kept a piece of PCB that is the same as the one mounted, and just measured the depth from that.


    It’d be nice if the Z went up during the tool change, but i think its like that since it’d be really slow to change the tool out. Other things I’ve noticed as just small things


    1. Camera chase mode, be nice if it automatically switched on the video feed if its not on.

    2. DRC/DRV, if there any it warns you with a popup box, especially about the forced isolation mode being off, I’ve missed it a few times and the board will likely not cut properly. Probably a good reason, but I don’t see it yet.

    3. USB camera doesn’t work well if there are two cameras on the same hub ,even on 2.0, haven’t tried it on a separate bus yet. Really not that big a deal, remote monitoring the CNC. Likely nothing to do with the PhCNC.

    3. Resizable video window, it gets in the way, you can make go away altogether, but I’d like it smaller sometimes.

    4. Video viewable in CAM mode, i use mplayerc.exe for this (Media Player Classic), you just have to keep switching and it doesn’t do the light/autofocus.

    5. Ability to record/remember each of the previously captured camera locations, that way you can build a larger area or refer back to it when you’re elsewhere with the camera, so a bitmap layer.


    I also noticed that when I did the thumbtacks for the mounted PCB boundary to lay the cut in CAM mode, when flipped to CNC mode, the image mirrors horizontally but its no longer inside the thumbtacks, not sure why yet.

    AccurateCNC 360 PCB Test 


    Here are the results! I’m pretty happy so far, haven’t studied them in exquisite detail but I’ll be doing that tonight!
