Vacuum Pressure Foot
Quick Start (printable) plus the full Installation & Operation Guide.
Quick Start (Printable)
This is the 1-page version intended to be printed and included in the box.
- Confirm spindle size (65mm or 80mm).
- Clamp adapter evenly around spindle. Do not overtighten.
- Seat magnetic base onto adapter until fully seated.
- Insert 2.5-inch hose cuff fully into port.
- Lower spindle until foot contacts material. Set Z offset accordingly.
- Power off before installation.
- Ensure secure clamping.
- Avoid aggressive hose side-load.
Full Installation & Operation Guide
Use this when you want the details: installation steps, hose routing, maintenance, and operating guidance.
1. Product overview
The Vacuum Pressure Foot is a spindle-mounted accessory designed to apply downward spring pressure and improve surface contact when machining thin sheet materials.
- Spindle adapter (65mm or 80mm)
- Magnetic pressure base
- Internal compression spring
- Vacuum port (2.5-inch hose cuff fit)
Thin sheet materials requiring improved hold-down and surface stability.
Heavy roughing passes or aggressive material removal.
2. Installation
Verify your spindle diameter matches the adapter (65mm or 80mm).
The adapter must clamp evenly around the spindle body.
- Position adapter at desired height.
- Tighten evenly.
- Do not overtighten.
- Ensure adapter sits square to the spindle.
- Align base with adapter.
- Allow magnets to seat fully.
- Confirm full contact and no rocking.
Remove debris before seating.
The port is designed to accept a standard 2.5-inch shop vacuum hose cuff (friction fit).
- Insert hose fully into port.
- No threading required.
- Avoid aggressive side tension.
If the hose applies side-load, re-route for smoother travel.
- Power off machine.
- Lower spindle until foot contacts material.
- Set Z offset.
- Begin test pass at conservative feed rate.
Maximum compression travel: approximately 3/4 inch.
3. Operating guidelines
- PVC up to 0.5 inch
- Plywood 1/8 inch
- Thin sheet goods
Reduce depth of cut and feed rate if chatter occurs.
The pressure foot improves surface contact but does not replace proper workholding.
4. Hose routing
Proper hose routing is critical.
- Avoid sharp bends.
- Minimize lateral pull.
- Ensure gantry travel is unrestricted.
Excessive hose tension may reduce stability.
5. Removing base for tool changes
The magnetic base can be removed for:
- Tool changes
- Bit inspection
- Cleaning
Re-seat carefully before operation.
6. Surface preparation
- Clean material surface.
- Remove chips under base.
- Ensure adapter is secure before operation.
Debris between base and material reduces effectiveness.
7. Maintenance
Periodically inspect:
- Magnet seating surfaces
- Compression spring movement
- Adapter clamp integrity
Remove dust buildup from port and base. No lubrication required.
8. Specifications
- Spindle compatibility: 65mm / 80mm
- Vacuum port: 2.5-inch hose cuff (friction fit)
- Compression travel: ~3/4 inch
- Material: PETG (3D printed)
- Design: Two-part system (adapter + magnetic base)
9. Safety
- Power off machine before installation.
- Verify secure clamping.
- Avoid heavy roughing passes.
- Monitor hose routing during operation.
