Common questions
FAQs
Does this replace a service visit?
No. This tool covers common shop-floor issues. Repeated faults, electrical work, or spindle rebuilds need a qualified engineer.
Why are fault codes a separate category?
The live site stored fault-code answers separately from the category dropdown. We expose them as a fifth category so controller messages are easier to find.
Can I search instead of browsing categories?
Yes. Use the search field above the categories to jump straight to a matching symptom across all areas.
