# Klipper Percentage Usermod
|
||||
This usermod polls the Klipper API every 10s for the progressvalue.
|
||||
|
||||
A corresponding curl command would be:
|
||||
```
|
||||
curl --location --request GET 'http://[]/printer/objects/query?virtual_sdcard=progress'
|
||||
```
|
||||
## Usage
|
||||
Compile the source with the buildflag `-D USERMOD_KLIPPER_PERCENTAGE` added.
|
||||
|
||||
You can also use the WLBD bot in the Discord by simply extending an exsisting build enviroment:
|
||||
```
|
||||
[env:esp32klipper]
|
||||
extends = env:esp32dev
|
||||
build_flags = -D USERMOD_KLIPPER_PERCENTAGE
|
||||
```
