No like:

if var.y_2 > var.y_3																; workpiece Zero coordinates
  set var.x_5 = var.x_4 + (COS(ARCTAN(var.m_1)) + COS(ARCTAN(var.m_2))) * var.d_probe / 2
  set var.y_5 = var.y_4 + (SIN(ARCTAN(var.m_1)) + SIN(ARCTAN(var.m_2))) * var.d_probe / 2

if var.y_2 < var.y_3
  set var.x_5 = var.x_4 + (COS(ARCTAN(var.m_1)) - COS(ARCTAN(var.m_2))) * var.d_probe / 2
  set var.y_5 = var.y_4 + (SIN(ARCTAN(var.m_1)) - SIN(ARCTAN(var.m_2))) * var.d_probe / 2

@Exerqtor
i tried this before in another case... everything unter the 2nd if wasnt done if the if doesn't match.
the problem of the missing end if

Exerqtor

@CanDo415
Then you simply must have done something wrong in the other case you're mentioning.

As reference to conditional construct have look at this.

jay_s_uk

@CanDo415 as @Exerqtor said, there's no end if.
Things have to be indented to be part of the if

dc42

@CanDo415 you also need to replace SIN by sin, COS by cos, ARCTAN by atan etc. See https://docs.duet3d.com/User_manual/Reference/Gcode_meta_commands#functions.

getting Error: line 89 column 20: meta command: unknown value 'atan'

@Exerqtor already pointed you at the proper doc - better read it completely. In the section Expressions, it says:

… when RepRapFirmware is running in CNC mode, any use of ( ) to enclose a subexpression or function parameter list must be within an expression enclosed in { }

Within your macro, you apply the curly braces inconsistently, Instead of

set var.m_1_rads = atan(var.m_1) ;  may not work in CNC mode, (var.m_1) is regarded as a comment

write

set var.m_1_rads = {atan(var.m_1)}

Same is true for other function calls like degrees().

In general, if writing macros, you should study the GCode meta commands completely and in-depth.
