Hello everyone,
This morning, I experienced a series of issues with my X1C that might interest some of you, especially regarding AMS automation.
It all started with an unexpected print failure: the final layer was incomplete, a classic case of under-extrusion (lack of material during extrusion, often during acceleration).
As a precaution, I removed the hotend and used a gentle cleaning method:
• Heated to 220°C (PETG HF), then applied light pressure to clear the nozzle.
• Cooled down to 100°C to stabilize, followed by manually pulling out the filament.
Everything seemed fine after reassembling the hotend and testing the extrusion: the filament came out properly. But the real issues began when I tried to unload the filament using the AMS.
The Troubles Begin:
1. AMS Goes Haywire:
• I couldn’t move the printhead, change the temperature, or stop the AMS. Everything was frozen.
• I had no choice but to power off the machine manually, which I avoid whenever possible because it’s risky.
2. Factory Reset Required:
• After restarting, I attempted another filament load via the AMS. The filament moved forward, then back, repeatedly, without completing the process. Once again, no controls were accessible, so I had to power off the machine a second time.
3. Investigations:
• AMS Check: Nothing unusual found.
• Nozzle Check: A small piece of debris fell out, which seemed to address part of the problem.
• Extruder Check: I found a broken piece of filament stuck inside, likely left over from earlier tests after clearing the nozzle.
A Suggestion for Developers:
I believe adding an emergency stop button to the control screen could allow users to regain control and safely halt operations in case of desynchronization between the AMS and the printhead. This would eliminate the need for risky power-offs.
Conclusion:
After a lot of disassembly and patience, everything is working again. But what a day…
If you’ve encountered similar issues or have tips to avoid such situations, I’d love to hear your feedback!
Thanks for reading.
