setParam() with ITEM_TYPE_PROGRAM
#1
Hi,

I am currently trying to acces the instruction parameters in a program from the Python API. I would like to do something similar to this example: https://robodk.com/doc/en/PythonAPI/examples.html#id5.

But the example doesn't work for me when I run it as it is.

I get the following output.
Code:
Program selected: gcode_example


Instruction: 0

TypeError: string indices must be integers

It looks like prog.setParam(ins_id) returns a string when it is supposed to return a dict. 

Is the example still up to date?

I am on RoboDK version 4.0.2

Thank you,

Hi Abraham,
The dictionary option to get/set instructions was added recently (after version 4.2).
I recommend you to update to the latest version of RoboDK.
