Problem using functions

infiniteloop

var testValue = sin(50)

Being just curious: do you run your Duet in CNC mode?

@anagh OK. I just had a look at the documentation, it says:

Sub-expressions may be enclosed in { } or in ( ). However, standard CNC GCode uses ( ) to enclose comments. So in CNC mode, RepRapFirmware treats ( ) as enclosing subexpressions when they appear inside { } and as enclosing comments when they do not. Therefore, 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 { }.

Try to enclose the expression in curly braces like this:

var testValue = { sin(50) }

but it keeps saying invalid file format.

What file extension does it have?

How did you create the file in the first place?

Can you test this macro?

testsinmacro.g

@infiniteloop good catch

Let's wait what happens …

@phaedrux I created the file by going to the macros tab, then "New File" and then writing this line in the file.
I tested the macro you uploaded. Here is the error message:
M98 P"0:/macros/testsinmacro.g"
Error: in file macro line 1 column 17: meta command: unknown value 'sin'

@phaedrux is running the machine in CNC mode an issue?
I still haven't been able to find a solution for this. I tried using math functions in macros and also sending them via the console. Both did not work.

Sure you can ask @Phaedrux any question you want, but in this case, I had already posted the answer: CNC mode isn't an issue, but it is different. Round brackets are a special case, so you have to enclose your expressions in curly braces. Did my sample work?

I just entered the expression

echo {sin(50)}

into my console, and I'm pretty sure it works - notably: in CNC mode. The result is -0.2623748

@infiniteloop Sorry, I missed your earlier answer. Your solution works. Thanks a lot for your help.
