Welcome back to my blog, where I share my latest adventures in 3D printing. This project focused on modifying a 3D printer for continuous printing using OctoPrint.
The goal: Adjust the OctoPrint settings and automation so the printer could start a new job immediately after finishing the previous one.
The challenge: Initial attempts either failed to start the next print or introduced calibration issues. Resolving those failures required troubleshooting both the automation and the printer state between jobs.
The process: After reviewing community guidance, I adjusted the OctoPrint code and fine-tuned the printer settings. The main issue was the transition phase between prints.
The breakthrough: Modifying the end G-code to reset the printer state, then adding a short delay before the next job, produced a reliable transition.
The result: After several trials, the printer began completing jobs consecutively without manual intervention.
The takeaway: The project reinforced the importance of patient, evidence-driven troubleshooting: identify the failing transition, test one change at a time, and adapt the workflow to observed behavior.
