### Basic Information:

Printer Model: kp3s  
 MCU / Printerboard: kp3s  
[klippy.log](https://klipper.discourse.group/uploads/short-url/gPjbZ3pbI5b2WX61w9ma4idkLxl.log) (6.2 MB)

When i request values from status reference object in the loop it always returned the same value even if the value was changed.  
That is the simple example of the issue.

[gcode\_macro test2]  
gcode:  
M140 S40  
{% for i in range (10) %}  
RESPOND TYPE=echo MSG=‘{printer.heater\_bed.temperature}’  
G4 P2000 # Wait for one second  
{% endfor %}  
M140 S0

> That’s because macros are evaluated before they are run. All the variables are “translated” before the macro is executed so if the macro itself changes the value of a variable, that change won’t be reflected during the same execution of the macro. To work around this, create a second macro called something like TEST\_RESPOND, have that macro do the RESPOND TYPE=error MSG=‘{test}’ line, and call TEST\_RESPOND at the end of TEST. Keep in mind that TEST\_RESPOND will need to lookup the value of the te…
