CTC PRUSA i3 Pro B Upgrade --> Mini Hypercube Evolution (HEVO)

myminifactory

It looks like you've shared a detailed breakdown of the components and costs associated with building a CTC Prusa i3 printer. Here are some observations and insights: 1. **Component Costs**: The total cost of the components is around $344, which is significantly lower than the estimated full build cost of at least $500. 2. **Print Quality**: You've noted that there's too much flex in the 2020 extrusions you initially used, leading to issues with printer stability and accuracy. This highlights the importance of choosing high-quality components for a successful print job. 3. **Klipper Printer.cfg File**: The provided Klipper printer configuration file is specific to the CTC Prusa i3 board in COREXY configuration. It includes settings for stepper motors, endstops, homing speeds, and more. Understanding these configurations is crucial for fine-tuning your printer's performance. 4. **Heated Bed Upgrade**: You've added aluminum tape to the heatbed, which has improved its heating performance significantly, reaching 65C in about 3 minutes. 5. **Additional Support**: Adding two 2020 brackets and two 2020 braces has helped stabilize the build, but you acknowledge that these components were not as strong as those from 8020.net. This underscores the importance of selecting high-quality materials for critical parts of your printer's structure. 6. **Flashing Firmware**: The instructions provided for flashing firmware using avrdude are specific to the AVR atmega1280 processor and highlight the need for precise configuration when working with custom or specialized boards like the CTC Prusa i3 board. 7. **Z-Probe Configuration**: The Z-probe settings in the printer.cfg file adjust the position of the probe, its speed, and how it interacts with the bed during probing operations. This detailed breakdown offers valuable insights into the process of building a 3D printer, from component selection to firmware configuration. It also highlights the importance of quality materials and precise setup for achieving reliable print results.
