[gwiethaus]

Describe the bug
When compiling for Arduino UNO, it generates several errors such as undeclared constant or undeclared function.

What is your hardware
Describe your hardware:

1. Arduino UNO and CNC shield v3
2. uCNC Version 2025-01-16
3. Windows 10
4. Visual Studio Code / Platformio

Additional context
I used the uCNC configuration generator from the website. Attached are the files and versions that were used.
Also attached is the terminal response file with the errors.

Hi there.
It's not a bug. You simply have incomplete definitions of the PWM pins. Also note that you are trying to use PWM were your don't have hardware PWM pins available.
Look at the UNO Pinout
The only pins that can do PWM are 3, 5, 6, 9, 10, and 11.

There was an issue on the Web Builder (for AVR specifically) that prevented the PWM channel to be correctly loaded from the default configuration. This issues was fixed yesterday.
