This text appears to be a guide for using a universal tool carriage with a 3D printer, specifically designed for the Creality CR-10. The author provides instructions on how to set up and use the carriage, including information on connections, calibration, and troubleshooting. Here are some key points from the text: 1. **Connections:** The author emphasizes the importance of proper connections between the carriage and the 3D printer's board. They suggest using a simple 4-pin dupont extension cable to connect multiple extruder outputs or thermistors. 2. **Calibration:** The author assumes that users are already familiar with steps/mm calibration and sensor calibration. However, they offer to help with these processes if needed. 3. **Probe offset:** The author notes that the probe's X offset needs to be established in Marlin, which can be done using M851 (although this may not work with all versions of Marlin). 4. **BLTouch probe height adjustment:** The author suggests using a 8mm shim to adjust the height of the BLTouch probe. 5. **Dual extruder setup:** The author provides instructions on how to set up dual extruders, including connecting both extruder outputs and thermistors. 6. **Laser control:** The author explains that if you can't free a PWM pin for the laser, you can connect it to your part fan output and control it with M106 Sx and M107. 7. **Changelog:** The author includes a changelog section that lists updates and new features added to the carriage design. Some potential areas for improvement or clarification include: * Providing more detailed instructions on how to set up the connections between the carriage and the 3D printer's board. * Clarifying the process for calibrating steps/mm and sensor calibration, as this may be a challenge for some users. * Offering more information on how to adjust the BLTouch probe height using the 8mm shim. * Providing more details on how to set up dual extruders, including any specific requirements or configurations. Overall, the text provides a good foundation for understanding how to use the universal tool carriage with a 3D printer. However, some additional guidance and clarification may be necessary to help users successfully implement this design.
