I am currently facing an issue with my plotter machine. Although it is properly responding to the commands sent to it, the cutter or pen tool isn't making contact with the vinyl at all. This has significantly impacted my workflow, as I rely heavily on this equipment for precise cutting and drawing tasks. I've checked the basic settings and connections, but nothing seems to resolve the problem. Could you provide some guidance or troubleshooting steps for this issue? I'm particularly interested in understanding if there are any specific maintenance tips or adjustments that I might be overlooking. Additionally, if there are any common parts that tend to wear out and might need replacing, I'd appreciate your insights on that as well. Thank you for your assistance!
