Automatic bed size using endstops
-
I want to use Duet not for a 3d printer. My project is to autoalign and measure a device ( e.g. a screen) to automatically apply touchscreen or protection covers. Because the devices have different sizes I want to automatically calculate the dimensions
-
In that case, does my description make sense on how to use G1 H3 to measure the high end of travel?

You might consider keeping the endstops for establishing the boundaries of the work area and use a "edge finder" type sensor on the XY gantry connected to a trigger which would execute the needed code.

@phaedrux Yes. Looks like that is the easy solution. Thanks.

@fcwilt That's what I was thinking. A magnetic sensor can do the trick I believe.

When I made my post I was thinking of my mill and how I use an edge finder to obtain the needed references to set the digital readouts so I can then move to the required locations for further machining.
And that sounded a bit like what you needed to do.

@fcwilt This is completely off topic but I'm looking for a better edge finder for my milling machine. What type do you use and/or recommend? I mostly machine non-ferrous metals so magnetic types won't work.

I have the first and second types listed and use them both depending on the specific circumstances.
The fourth one is new to me and it looks interesting - if somewhat expensive.

@fcwilt Thanks. I use the second type but something has gone wrong with it - it doesn't "jump" when I go past the zero point like it used to which makes it difficult to tell exactly where the edge is. But it was a very cheap one - maybe I'll just buy a better quality one of the same type.

I would go for the fourth one - then you can tell me if I should get one.

That's not going to happen - one of those costs more than one months state pension and I need to eat
