Rolling Plotter with lots of Possibilities

thingiverse

It seems like you have a comprehensive setup for your plotter, including a Raspberry Pi, Klipper firmware, and a custom Z-axis design using a servo. You've also provided a detailed bill of materials (BOM) spreadsheet and a build guide. To summarize, here are the key points: 1. **Firmware:** You're currently using Klipper firmware, which you found to be more suitable for your plotter's requirements. However, you've also considered Marlin and Grbl firmware options. 2. **Power Supply (P/S):** You're planning to use a 6-amp P/S, which should be sufficient for your setup. If you decide to go with the Meanwell P/S option, you'll need to modify your design accordingly. 3. **Z-Axis:** Your Z-axis uses a servo instead of a stepper motor, which is why you chose Klipper firmware. You've also provided a link to the remix of the Z-axis design, which includes optional mounts for different motors. 4. **Parts to Print:** You've listed the required parts to print, including wheels, tires, belt connectors, and limit switch mounts. You've also mentioned that some parts can be purchased if you prefer not to 3D print them. Overall, your setup seems well-planned, and I'm sure it will serve as a great reference for others looking to build their own plotter. Here are some suggestions: 1. **Consider Using a More Powerful P/S:** While a 6-amp P/S might be sufficient for now, consider using a more powerful one (e.g., 12 amp) if you plan to add more features or larger motors in the future. 2. **Explore Alternative Firmware Options:** Although Klipper seems to be working well for you, it's always good to explore other firmware options like Marlin and Grbl to see if they offer any advantages or benefits for your specific use case. 3. **Add More Sensors:** Consider adding more sensors (e.g., temperature, vibration) to monitor the performance of your plotter and make adjustments as needed. I hope this helps! If you have any further questions or need additional assistance, feel free to ask.
