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.

Quick Start (5 minutes)
  1. Confirm spindle size (65mm or 80mm).
  2. Clamp adapter evenly around spindle. Do not overtighten.
  3. Seat magnetic base onto adapter until fully seated.
  4. Insert 2.5-inch hose cuff fully into port.
  5. Lower spindle until foot contacts material. Set Z offset accordingly.
Safety reminder
  • Power off before installation.
  • Ensure secure clamping.
  • Avoid aggressive hose side-load.
Recommended for thin sheet materials. Not intended for heavy roughing passes.

Full Installation & Operation Guide

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.

The system consists of
  • Spindle adapter (65mm or 80mm)
  • Magnetic pressure base
  • Internal compression spring
  • Vacuum port (2.5-inch hose cuff fit)
Intended use

Thin sheet materials requiring improved hold-down and surface stability.

Not intended for

Heavy roughing passes or aggressive material removal.

2. Installation

Step 1: Confirm spindle size

Verify your spindle diameter matches the adapter (65mm or 80mm).

The adapter must clamp evenly around the spindle body.

Step 2: Mount adapter
  1. Position adapter at desired height.
  2. Tighten evenly.
  3. Do not overtighten.
  4. Ensure adapter sits square to the spindle.
Tip: Leave 1–2 inches of vertical adjustment room initially.
Step 3: Attach magnetic base
  1. Align base with adapter.
  2. Allow magnets to seat fully.
  3. Confirm full contact and no rocking.

Remove debris before seating.

Step 4: Connect vacuum hose

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.

Step 5: Set compression height
  1. Power off machine.
  2. Lower spindle until foot contacts material.
  3. Set Z offset.
  4. Begin test pass at conservative feed rate.

Maximum compression travel: approximately 3/4 inch.

3. Operating guidelines

Recommended materials
  • 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

For best results
  • 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.
