    Hi,

    I’ve recently been gifted with a tinyg controller that I’ve started using with my chinese made 6040 CNC machine.  It was very easy to wire up and it worked a treat from the first command. Motion on all 3 axises was smooth and appears to be accurate.

    My next step is to start wiring up limit switches and I was thinking that I’d quite like to have a tool height probe and also a center finder.   Kind of like how its done in this video:  https://www.youtube.com/watch?v=IWglgxdFpVE

    The hardware itself is obviously simple enough – they are both just N/O switches , however I’m not sure what the best/simplest way to get my tinyg to support it is.

    Can you (or anybody) suggest an appropriate place to start, or are you already working on/have implemented those features?

    Thanks

    Let me take a closer look at this. G38.1 probe cycles are on the list but not done yet.

    For now you can navigate to your zero point and set a G92 offset to 0,0,0  (G92x0y0z0). It’s not automated, but it should work – although with less accuracy.

    Thank you Alden, that’ll work fine for now.

    Have to say I’m very impressed with the tinyg – very easy to set up and use.

    Hi folks,

    Any news on this subject ?
    I’d like to use a tool length sensor such as this http://tinyurl.com/l88xufm

    I guess, it would be possible by reversing the Z axis and do a Z homing only, but that is definitely not clean 🙂

    Thanks
