Angle deviation

Hi! I'm new here.

Is there any plugin to linuxcnc that finds the angle deviation? It's exactly shown in the video below (time 1:04):


Eventually can you tell me how to write that plugin?

Greetings

Try this, just for angle deviation. Measure 2 points on one side of your workpiece.
Your probe must be positioned at startposition xyz. Feed is fixed 100%, otherwise remove M50P0.
Metric G21. CS 1 (G54) is used by this routine. Use another cs for machining.
Global param #<_ANG> contains measuring result.
use o<check_r_cor> in preamble recommended, to find R rotation left behind in any cs, to avoid bad experience.

1 [Traveldistance (+ -) to measuring point]
2 [Distance (+ -) between measuring points]
3 [Travel axis 1 or 2]

o<adev> call [-6] [-65] [2]
G10 L2 P2 R#<_ANG>
o<check_r_cor> call

There is also the probe screen, and angular alignment is one of the options there:

Also note that LinuxCNC can rotate the coordinate system around Z to compensate for out-of-square workpieces:
