Combining edge/ corner finding and angle measurement

[SebastianM81]

Hey Terjeio,
first of all I wanna thank you for the incredible work that you do with ioSender. It really makes my life easier :)

To make the tool even more awesome, I might have an Idea for improvement...

I realized that its not possible with the current implementation to precisly touch-off a workpiece that is skewed / rotated on the baseboard.
Let me explain:
Say I have an aluminum block that is rotated by 45degrees (extreme example) and I wanna to the edge / corner fiding. IOsender will probe one point per side, but this will always lead to a wrong (assumed) corner. (see example in first picture).
Then, I would do the angle probing, but as the origin of the part is already wrong, I will end up with right shape and angle, but at the wrong position... (see screenshots 2 and 3).
And depending on the positions of the probing points, I can end up with several different results for the same workpiece (scenario 1 vs 2 in the pictures).

I have used Estlcam a few years ago, and Estlcam has another approach for this... when doing the Edgefinding, Estlcam probes 2 points on the first side and 1 point on the second side... so it basically combines the corner finding and angle measurement.

I hope you understand what I mean.
Again - I love Iosender, but if you want to do som really precise cuttings, this offset that I described is a bit annoying.

Regards!

New edge version up that that has initial support for an option to probe a third point to determine and set X0,Y0:

The option is only available/usable for a right angled lower left corner, I do not know if there is any need to add it for the other corners and/or arbitrarily angled corners - I have left that out for now as it will add a lot more complexity.

Functionality should be similar as shown in this Estlcam video.

Be aware that I have not tested this extensively, so please be careful whe using the option.
