Drill allocation problems

Former Member

G'day all

We have a PCB milling machine that requires correct numbering (T1,T2,T3 ..etc) to select the the correct drill bit with it's ATC(Auto Tool Changer)

This is were we run into problems, in that, I am unable to get eagle to allocate a specific tool number to a drill. I have set the correct numbers to drills under Options settings drills but the cam processor ignores it and sets the tool numbers to  drills used. eg if only six drills are used it will ignore the numbering I require and allocate the umbers 1 - 6.  That is to say if I use 0.7,0.8,0.9,1,1.1,3 mm drills and I have set them to be 0.7 to be T2, 0.8 - T3, 0.9 - T4, 1 - T5, 1.1 - T6, and 3 - T11 to align itself with the milling machine. It  allocates it to T1-T6.  You may say just live with and adjust the milling machine every time you use it but we mill different boards at the on time  and if the each have different allocations for tools it just doesn't work.  There must be a way to get eagle to obey the drill allocation? anyanswers ? also as we only have metric drills I would like it to round up to the nearest Metric drill in the drill list when the footprint gives me a imperial drill size, again any answers

    This is were we run into problems, in that, I am unable to get eagle

    correct numbers to drills under Options settings drills but the cam

    processor ignores it and sets the tool numbers to  drills used.

     

    That's a completely different thing. Those assignments you make in the

    options are only for visualisation of the different drill diameters by

    different symbols when displaying the drills/holes layers.

     

    They are not in any way related to the tools that are used during CAM

    processing.

     

    eg if only six drills are used it will ignore the numbering I require

    and allocate the umbers 1 - 6.  That is to say if I use

    0.7,0.8,0.9,1,1.1,3 mm drills and I have set them to be 0.7 to be T2,

    0.8 - T3, 0.9 - T4, 1 - T5, 1.1 - T6, and 3 - T11 to align itself

    with the milling machine. It  allocates it to T1-T6.

     

    You need to be more specific here. Which device did you select in the

    CAMP? Most drill file formats allow for using separate tool files, and

    the tools are of course assigned accordingly.

     

    For example, I use the SM1000RM2UTAASM1000RM2UTAA drill file format (resp. "device" in the

    CAMP). For this, you can easily set up your personal tool list as a

    simple ASCII file (say "mytools.drl"):

     

    T02 0.7mm

    T03 0.8mm

    T04 0.9mm

    T05 1.0mm

    T06 1.1mm

    T11 3.0mm

     

    Then, when running the CAMP, specifiy this as the tool file. Take care

    to allow for small tolerances (say +/- 3%) since some libraries may

    contain odd (or imperial) drill diameters which need to be rounded.
