Setup notes and briefing numbers for Probe Kit.
Probe plate dimensions and fit
Probe Kit specs gives the technical detail for probe-related tooling used during CNC setup. Confirm compatibility, dimensions and the parts needed for accurate machine referencing.
Probe Kit specs should state the plate material, lead type, cable length and overall thickness used for Z zero setting on a CNC router. Brass and aluminium contact plates are common, but the exact height must match the value entered in the control software to avoid a false tool length offset. In South African workshops, dust from MDF and board cutting can insulate the contact face, so the plate needs regular wiping before each reference cycle.
Check the clip connection, plate face and cable strain relief before the first touch-off of the day. A worn crocodile clip, chipped insulation or a scratched plate can interrupt continuity and give an inconsistent reading. Keep the setup note near the machine so the probe height, macro call and safe retract distance are easy to confirm during changeovers.
What the specs must cover
The probe kit components used for machine referencing include the plate, lead, connector style and any matching holder or storage piece. It also needs the measured plate height, contact method and compatible controller settings for routine setup work. Clear naming matters when the same router runs spoilboard surfacing in the morning and aluminium parts later in the shift.
Use these Probe Kit specs to confirm whether the kit suits your spindle, controller and working method before adding it to the tooling list. Include the probe height value in the machine notes and keep the matching macro number with the job paperwork for repeat setups. Bit orders depend on the shank size, the material and the router you run them on.

Workshop conditions that affect probing
Probe readings can change when the machine table carries resin, fine dust or oxidation on the contact area. In Gauteng shops, dry dust buildup is a frequent cause of failed contact, while coastal humidity around Durban and Cape Town can accelerate corrosion on clips and exposed metal parts. Older routers also need extra attention to earthing and cable routing when probe inputs behave unpredictably.
Store the plate in a dry holder rather than loose in a drawer with spanners, collets and offcuts. Salt air, coolant residue and board dust all shorten the life of bare contact surfaces if cleaning is skipped. After load-shedding or an emergency stop, run a fresh probe check instead of assuming the previous offset is still correct.

Probe setup values to note
Record the exact plate thickness, retract height, probing feed rate and input assignment used on the machine. Add the controller brand and the macro or routine name so the operator is not guessing during a tool change.
Keep a log of any missed triggers, double touches or offset errors against the cutter and material being run. That makes it easier to spot whether the issue sits with the probe kit, the wiring or the machine setup itself.
