### **Cons of the MKS PC89300 RPS Controller Display PCB**

1. **Requires Additional Components for Full Functionality**

- The **PC89300 is a controller board**, not a standalone display. To use it, you need:

- A **compatible printer board** (e.g., SKR, RAMPS, or a modified Ender board).

- The **Astron Paragon display module** (sold separately).

- Possible **wiring modifications** if integrating with an existing setup.

- This adds **extra cost and complexity** compared to a plug-and-play solution like a **Duet WiFi**.

2. **Learning Curve for Setup and Configuration**

- Users unfamiliar with **Marlin/Klipper firmware** may find the **initial setup challenging**, especially when dealing with **pin assignments, wiring, and menu customization**.

- Some users report **issues with touch calibration** if not set up correctly.

3. **Limited Built-in Connectivity Options**

- Unlike **Duet or Moonlight controllers**, the PC89300 does **not include built-in Wi-Fi, Ethernet, or USB-C connectivity** (depending on the model).

- **Serial communication** (USB or microSD) is typically required for firmware updates and monitoring, which may be inconvenient for some users.

4. **Potential Compatibility Issues with Certain Printers**

- While the PC89300 is **versatile**, some **budget or custom printer boards** may not support it due to **pinout differences or power requirements**.

- Users with **very old or non-standard printer setups** may need **custom wiring or adapters**.

5. **No Built-in Power Supply (Requires External PSU)**

- The PC89300 **does not include a power supply**, meaning users must provide a **compatible 12V or 24V PSU** (depending on the printer board).

- This adds **another component to manage** and can be a point of failure if not properly selected.

6. **Firmware Limitations Compared to Advanced Controllers**

- While Marlin/Klipper on the PC89300 is **capable**, it **lacks some advanced features** found in **Duet or Moonlight controllers**, such as:

- **Built-in PID tuning**.

- **Advanced motor control (e.g., microstepping adjustments)**.

- **Some Klipper-specific optimizations** (though possible with modifications).

- Users seeking **the absolute best performance** may need to **supplement with additional hardware** (e.g., a separate power supply for the hotend).

7. **Potential for Overheating in Poorly Ventilated Enclosures**

- While the **metal backplate helps with heat dissipation**, some users report **overheating issues** if the printer is **not well-ventilated** or if the controller is **overloaded with high-current components**.

- Proper **cooling and spacing** are necessary to prevent long-term damage.

8. **Dependence on Third-Party Support for Troubleshooting**

- While MKS provides **good documentation**, some issues (especially with **custom firmware or wiring**) may require **community troubleshooting**, which can be time-consuming.

9. **Not a Direct Replacement for Some Printers**

- Unlike **Duet s modular approach**, the PC89300 **cannot simply replace an existing controller** without **modifications to the printer board**. Users may need to **solder new connections** or **re-wire their setup**.

10. **Occasional Firmware Instability**

- Some users report **occasional crashes or menu freezes**, particularly when using **custom Marlin builds or experimental Klipper configurations**.

- This is **not unique to the PC89300** but is something to consider when evaluating stability.
