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?

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

This discussion might be interesting:
forum.linuxcnc.org/40-subroutines-and-ng...a-plasma-table#29170
There is also the probe screen, and angular alignment is one of the options there:
forum.linuxcnc.org/49-basic-configuratio...h-probe?limitstart=0
Also note that LinuxCNC can rotate the coordinate system around Z to compensate for out-of-square workpieces:
