Automatic angle compensation possible?

[mr_cg]

Hello,
i would like to know if it is possible - natively or by additional plugin - to automatically compensate staight workpieces which are not (or cannot because of it's size) fixed along x or y axis?
Some CNC SW have the feature to measure two points on workpiece edge along x or y axis and then automatically compensate every x or y movement based on the angle deviation.

Is there any solution available for this?

Thanks for your help.

edge probe and then use G68 to rotate

Thanks for the hint about G68.

How is it possible to automatically calculate the required rotation by probing the edge on two points?
Thx

You can write a simple macro doing math angle function from the probed points coordinates to calculate the rotation angle and then do a G68 with that angle.

You need to use trig to calculate it.
The distance between the two probe points is the base of a 90° triangle.
The difference between the probe points is the height of the triangle.
This is enough info to calculate the angle using trigonometry.

I just realised that the probing plugin on the tools/probe page of the UCCNC already have the 2 point probing and angle calculation. So it is there, you just have to use it.

When I use G68 in UCCNC, for example G68 X0 Y0 R0.34 then UCCNC show me R68 R0.4 in status line. Is this just a display issue? Or is it really rounding my value? How to retrieve the value that is in place? Thanks.

That is rounded to fit on the screen. You can call exec.GetRotate(out double Rx, out double Ry, out double Angle) from a macro to get the angle.

Thanks for the clarification

Sorry, could not find tools/probe page. Can you please share the link to this page? Thanks!
