Pre-flight checklist

Print it. Tick it, in order, every time.

Print this section on its own and keep it at the machine. Tick every line, in order, every time. If a line cannot be ticked, stop and ask.

Before power

  • Signed-off operator present; second person knows the E-stop (wall pendant by the monitor)
  • Glasses, ear protection; no gloves, loose sleeves, hair, lanyards
  • Table and rails clear of tools, offcuts, clamps from the last job
  • Dust hose on the foot, brush skirt intact
  • Key OFF and in your pocket for the bit change; bit correct and sharp, collet clean, nut torqued, stick-out minimal
  • Stock: thickness measured and written down, flat on the deck
  • Hold-down planned: screws/clamps outside every toolpath, tabs or onion skin for freed parts

Power and zeroing

  • Control box on → E-stop twisted to release, pendant Reset pressed (input 4 not flashing) → PC on, SB3 open in Move/Cut mode (SM)
  • Spindle RPM Control window open; interlock key in and ENGAGED; dust collector switched on at the collector
  • C5 warm-up at the start of the day or after 4 h idle
  • C3: machine homes on both proximity switches without complaint
  • Read the .sbp header: mm, and which surface is Z0 (&PWZorigin: material top or table), feed, rpm, first Z move sane
  • Jog to the CAM file’s XY origin (centre or corner); Z2 (or ZX/ZY). The drawing uses the material centre
  • C2: clip in place on the carriage plate, plate under the bit on the surface the file expects; touch plate to bit — input 1 lights and goes out; run C2 (two touches, lift); clip stays on the plate, Z-zero plate back in its holder on the car
  • Keypad closed before FP

Running

  • Air cut a new file: FP with Offset = 3D, bit raised above the stock by more than the file's deepest cut, spindle may stay off; then Offset = No Offset and C2 again if you moved Z
  • RPM typed in the Spindle RPM Control window and Enter
  • FP → prompt “Press START on control before pressing OK”: pendant START, spindle at commanded speed, VFD shows the rpm, then OK (no separate VFD RUN)
  • Hand near the spacebar, E-stop in reach, for the first plunge and the first pass
  • Watch the chips: ribbons/curls good, dust and smoke bad
  • Never leave the room while it runs

After

  • File finished/stopped, spindle stopped; raise Z and jog clear with everyone outside the cutting area; collector off
  • Key OFF and removed, keypad closed, no loaded/paused file before clearing parts, screws and offcuts; deck vacuumed, racks and rails brushed
  • Bit removed, cleaned, back in its place; collet checked
  • Material, cutter, feed, rpm and any fault recorded in your job notes; problems told to staff
  • Machine left powered for staff. Users never power down; E-stop is for emergencies
