Problem using functions

anagh

I am trying to use functions like sin, tan, abs, etc. But I am get an error saying "Error: meta command: unknown value 'sin'".
All I am doing right now is sending "echo sin(50)" and getting this error. Am I missing something? I have tried using different kinds of brackets for the functions to get the same result. Any help would be appreciated. Thanks!
Edit: I am using version RepRapFirmware for Duet 3 MB6HC 3.4.0

@anagh
In what context are you using the command?
The function on its own is not a command.
If you're using the console, try
echo sin(50)
or in a macro

var testValue = sin(50)
echo testValue

anagh

@owend I was just trying to use the console. After your comment, I created a test macro which just has this line in it:
var testValue = sin(50)

When I run the macro, this is the error I get,
Error: in file macro line 1 column 17: meta command: unknown value 'sin'

It works for me on Duet2 stand alone.
I'm running 3.4rc1.
Maybe it's an SBC thing?

anagh

@owend strange. I am not sure how to fix it though.

Can you send M122 and copy paste the result here?

When I run the macro, this is the error I get,
Error: in file macro line 1 column 17: meta command: unknown value 'sin'

Can you post the actual macro being used please?

anagh

@phaedrux
var testValue = sin(50)

This is the trial macro I tried to run which contains only this one line. I tried using other functions like tan, abs, etc. as well. But I get the same error.

Phaedrux

I mean can you post the actual file so we can see the actual text contents?

anagh

@phaedrux This might be me doing something silly or missing something. I downloaded the macro file on my computer. Now I am trying to go to "upload file" and select the macro file, but it keeps saying invalid file format.
Also, the macro file contains only this line and no other text in it. I tried sending this same line using the console as well but I get a similar error:
Error: meta command: unknown value 'sin'

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

anagh

@infiniteloop yes.

infiniteloop

@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

Phaedrux

@infiniteloop good catch

good catch

Let's wait what happens …

anagh

@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'

anagh

@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
