Reference parameters, often called "homing" parameters, define the machine's absolute zero point. If these are slightly off, your tool offsets and soft limits will be incorrect, potentially leading to crashes or scrapped parts. Axis parameters:

• Axis parameters:
  • X-Axis (Parameter 85): On a lathe, home X is usually at the machine's maximum stroke (e.g., 200mm diameter). Better tip: Leave 5-10mm of unused travel past home. This prevents the nut from hitting the hard stop.
  • Z-Axis (Parameter 86): Home Z is usually just touching the tailstock limit. Better tip: Set it 2mm inside the limit switch trip point to avoid switch bounce errors.
