Set up & repeat
Jig setups: repeat the position, not the mistake
Plan a repeatable holder, a reference corner and clearance checks before making the same part again.
The short answer
A jig guides an operation; a fixture holds the work. A useful setup locates each blank consistently and holds it securely without putting hardware in the cutter's path. A locating stop is not a substitute for clamping.
- Locate the blank
- Secure the work
- Check clearance
Start with one repeatable reference
Choose which face sits down and which edges touch the locating stops. Mark those faces on the setup sheet. Remove trapped chips before loading another piece: a tiny obstruction can change where it sits.
Plan space for loading and removing the finished part. A fixture that makes the cut easy but traps the part afterward is not ready for production.
Separate locating from holding
A stop tells the blank where to sit; holding keeps it from lifting, sliding or rotating during the operation. Choose a workholding method approved for the machine, stock and forces involved.
Draw every clamp, screw and stop into your setup notes. Check the complete movement of the cutter, spindle housing and dust boot—not only the line being cut. Protect hands and never reach into moving equipment.
Prove one part before multiplying it
Use the machine's supported simulation and clearance-check procedure, then make one representative part with guarding and dust collection in place. Inspect its dimensions and finish before authorizing the batch.
For a laser, use a fixture material explicitly approved for that laser. A CNC holder is not automatically laser-safe. Never bypass an enclosure or safety switch to fit a jig.
Keep a setup record
Give the fixture an ID. Save a photo, reference faces, file revision, hardware list and the approved sample together. State what requires rechecking: a new blank thickness, a moved stop, a different cutter or a repaired holder.
If a part moves or a collision occurs, stop safely and isolate the machine before investigating. Set aside affected parts; inspect the holder and tool, establish references again, and approve another sample.

Carbide 3D
Crush-It Essential Clamp Set
A manufacturer-listed workholding kit designed around the Hybrid Table and M6 hardware, including clamps and locating stops.
Check first: Verify bed compatibility, hardware engagement and clearance. Polymer parts still contain metal hardware; never plan a collision.

Make a decision you can explain
| Situation | A practical approach | Check before proceeding |
|---|---|---|
| One-off blank | Simple approved workholding | Support and clearance through the whole job |
| Repeat blank | Dedicated locating stops plus secure holding | Variation in stock and removal access |
| Changed stock or fixture | Recheck references and first part | Do not assume the previous approval still applies |
A good jig makes the correct position easy to repeat; it does not make an unchecked program safe.
A guided conversation
Talk it through
Use these prompts with a friend, a customer or your workshop group. Open each one for a place to start—nothing is posted or collected here.
Is the stop also doing the job of a clamp?
Try to explain how each direction of movement is restrained. If the answer relies on a locating stop alone, reassess the workholding with the machine's guidance.
What could collide even when the cutting line looks clear?
Include the full tool assembly and extraction attachment in the clearance review. Check travel between cuts, not only cutting moves.
What would invalidate the approved setup?
Write a short change list: thickness, cutter, holder, reference position and file revision. Any relevant change calls for a new setup check.
