    Hi

    Does anyone have a script that can find the edge of a work piece like GRBLs edge finder?

    Im after the same as shown in the video for mach3 in metric

    The first link below references the second, not sure if you've seen this before?

    You think that's too expensive? You're not a Model Engineer are you? :D

    thank you ill have a read now. Im hoping to achieve the same method of zeroing as grbl. You set tool size and it measures the outside of the probe.

    anyone got mach3 script can do the same as in the video?

    It requires tool diameter and mesaures the outside edge of the finder.

    Did you read the CNC Zone thread?
    The first post is on the last page and the last post on the first which can be confusing.
    There are instructions for the screenset and setting up to get the probe working.

    i did get a little confused with it lol. I cant seem to find what im after. I have seen some scripts but they dont take into account the tool diameter.

    The thread that Magicniner has pointed you at has all the information you need, but not necessarily in a very easily-used format. There is a lot of "noise" as well in that thread which doesn't help. I used that thread to get the base info I needed for my own tool length probing macros so I can sympathise if you are not a natural coder yourself. However, in that case (and bearing in mind that you would probably need to tweak anything you find for your own machine), one easy way forwards might be to look at Gerry's 2010 screenset which includes some very powerful XYZ probing tools. For $20, it might be a cost-effective alternative to semi-rolling your own.

    Just a thought.

    Probing for anything than than Z should be ideally done with a probe, using tools could result in errors unless they have the required rotational symmetry and are unworn.

    If you were to explain why you need this functionality I'm sure there is a solution, it may even be as simple as rigorous work planning and fixturing,

    Regards,

    Its just the way i ahve done it using grbl and find it very good and great for accuracy. it would be nice to implement the same for mach3. Mach3 has alot more features that will make my machine more accurate so this is why i want to use it.

    Cool, keep reading up, you'll get it sorted.
