Maybe a bit too deep(0.5mm), but it exceed my expectations anyway
    Quite deep, but for 1st cut can not complain.
    May I ask what kind of software was used for circuit design?
    Eagle pcb takes me ages and is inaccurate with leg component distance.

    Thanks

    You'll find Eagle is very precise, provided that you select the correct library components.

    *EDIT* provided you're not referring to axial-lead components, where obviously it's down to the designer as to the intended pitch to form the leads.

    Just realised this was a 4 year old post

    I tried Eagle and did not find it easy, after trying some of the other usual suspects I settled on dipTrace to produce the designs and the FlatCAM to do the isolation routing. Within the last few days I came across copperCAM which looks useful. Here is a link, I have not tried it yet.

    I think that this was my first attempt using that software around 2018/2019 on a Bridgeport mill.

    I made a vacuum chuck to hold it down flat. Measurements showed that it was almost perfectly flat and there was no need for level mapping software to correct the G-code for level.
