CNC Routers at Loveland CreatorSpace

Loveland CreatorSpace operates two CNC routers for precision cutting, carving, and machining of wood, plastics, and other approved materials. CNC machines are powerful, high‑precision tools that require training, planning, and careful operation.

This page outlines the equipment available, required training, safety expectations, and best practices for using the CNC routers responsibly.

1. Overview

Our CNC routing area supports:

• Furniture components

• Signs and engraving

• Sheet‑goods cutting

• 2D and 2.5D machining

• Complex shapes and patterns

• Jigs and fixtures

• Prototyping and hobby projects

CNC routers are restricted tools — authorization is required before use.

2. Available CNC Routers

Loveland CreatorSpace operates two CNC machines:

AvidCNC PRO4896 (Large Format) (Coming Soon!)

• Full sheet capacity (4' × 8')

• Industrial‑grade rigidity and precision

• Ideal for plywood, MDF, hardwood, and large projects

• Best for cabinetry, furniture, and large signs

• Requires CNC authorization

• High‑power spindle

• Mechanical or vacuum workholding (depending on final setup)

• Mach4 control system

750mm x 750mm CNC Router (Mid‑Size)

• Half‑sheet capacity (4' × 4')

• Ideal for smaller projects, signs, jigs, and prototypes

• Great for learning CNC basics

• Requires CNC authorization

• Lower power than the AvidCNC, but highly capable

• VCarve + standard controller workflow

3. Required Training

Before using any CNC router, members must:

• Complete the CNC Orientation

• Complete the Tool Authorization Checklist

• Demonstrate safe operation of the machine

• Understand workholding (clamps, screws, vacuum, fixtures)

• Learn proper toolpath creation and simulation in VCarve

• Know how to set X/Y/Z zero points

• Understand feeds, speeds, and bit selection

• Learn emergency stop procedures

• Know how to monitor a job safely

4. Safety Rules

General CNC Safety

• Never leave a CNC router unattended while running

• Keep hands clear of the spindle and moving gantry

• Secure workpieces properly — loose material is dangerous

• Use appropriate bits for the material

• Verify toolpaths before running

• Watch for smoke, burning smells, or chatter

• Stop the job immediately if something looks wrong

• Keep the area clear of debris and offcuts

Material Safety

Approved materials include:

• Wood (softwood, hardwood, plywood, MDF)

• Acrylic

• HDPE

• Foam

• Certain plastics (ask if unsure)

NOT approved:

• PVC

• Polycarbonate

• Fiberglass

• Metals (unless specifically authorized)

• Unknown plastics

5. Software & Workflow

Loveland CreatorSpace uses VCarve as the primary CAM software for both CNC routers. Members may design their projects in any CAD program, but toolpaths must be generated in VCarve unless otherwise authorized.

1. Design

Use your preferred CAD software (Fusion 360, SketchUp, Illustrator, Inkscape, etc.) and export to DXF/SVG.

2. CAM (Toolpath Creation in VCarve)

• Import your design

• Select the correct CNC machine (AvidCNC PRO4896 or 4×4 router)

• Choose tools (bits)

• Set feeds and speeds

• Define passes and cut depths

• Add tabs

• Simulate toolpaths

• Export G‑code

3. Machine Setup

• Secure material

• Install the correct bit

• Set X/Y/Z zero

• Verify toolpaths

• Frame the job

• Turn on dust collection

4. Run the Job

• Start the job

• Stay with the machine

• Watch for issues

• Pause or stop if needed

5. Cleanup

• Vacuum chips

• Remove material

• Clean the bed

• Return bits and tools

• Leave the area clean

6. Reserving a CNC Router

Post a message in Slack → #cnc_router_table when you begin a job:

• Which CNC you’re using (AvidCNC or 4'×4')

• How long you expect your job to run

Example:

“Using the AvidCNC — job will run about 2 hours.”

7. Bits, Tools, and Workholding

Bits

We maintain a selection of CNC bits for:

• Surfacing

• Pocketing

• Profiling

• V‑carving

• Engraving

• Specialty cuts

Members must inspect bits for wear and return them properly.

Workholding

Approved methods:

• Screws

• Clamps

• Cam clamps

• Vacuum hold‑down (if available)

• Double‑sided tape

Never rely on friction alone.

8. Common Problems & Troubleshooting

• Poor cut quality → Check feeds/speeds, bit sharpness

• Burning → Increase feed rate, reduce RPM

• Chatter → Slow down, improve workholding

• Bit breaks → Reduce depth per pass

• Misalignment → Re‑zero axes

• Machine stops → Check G‑code or emergency stop

9. Respecting Shared Equipment

• Communicate before running multi‑hour jobs

• Follow the Ask Before You Touch policy.

• Report dull bits or damaged spoilboards

• Clean thoroughly after each use
