• Power supply: 24 V / 4 A
• Safety & I/O: Limit switches, emergency stop, Z-probe with LED
• Extras: Offline controller, Genmitsu app support, Wi-Fi module, 4th-axis support

Strengths

• Compact footprint: The relatively small machine size makes the 4040 Reno easier to fit into apartment workshops, tight benches, or shared spaces.
• Beginner-friendly setup: Semi-assembled modules and clear documentation help first-time users get carving quickly without a complicated mechanical build.
• Decent accuracy for light work: With a claimed running accuracy of ±0.1 mm, it is suitable for detail on small wooden parts, signs, and acrylic pieces.
• Good safety feature set: Limit switches, an emergency stop button, and a Z-probe are all included out of the box.

Limitations

• Smaller work envelope: At 400 × 400 mm, the work area is fine for small projects, but it can be restrictive for larger signs, furniture panels, nested layouts, or multi-part jigs.
• Modest spindle power: The 75 W spindle is appropriate for light cutting in wood, MDF and plastics, but you will need shallow passes and patience for harder woods or soft metals.
• Less headroom for growth: While it can be upgraded, the frame size and stock power limit how far you can push feeds, speeds, and material choice as your skills grow.

Overall, the 4040 Reno is a solid choice if you’re just stepping into CNC, have limited space, and mainly want to run small woodworking or acrylic projects without a big upfront investment.

TwoTrees TTC 450 Pro Overview

The TwoTrees TTC 450 Pro is a more robust desktop CNC platform aimed at serious hobbyists and small businesses. It keeps a compact, bench-top form factor, but stretches the working area to 460 × 460 × 80 mm and adds a stiffer frame, touchscreen control, and clear upgrade paths for spindles, rotary axes and laser modules.

Key Specifications

• Working range: 460 × 460 × 80 mm (18.1 × 18.1 × 3.14 in)
• Machine size: 742 × 689 × 413 mm
• Frame structure: Sheet metal + aluminum profile + injection-molded parts + stainless steel
• Spindle motor (standard): 775 brushed DC motor
• Spindle speed: approx. 8,000–30,000 RPM (depending on installed spindle option)
• Supported tool diameter: 0.5–7 mm (ER11 collet)
• Engraving accuracy: 100 ± 0.05 mm
• Maximum engraving speed: 800 mm/min
• Controller: 32-bit GRBL firmware with 3.5" IPS capacitive touchscreen
• Connectivity: TF card, USB, Wi-Fi (2.4 GHz)
• Power supply: 24 V / 3 A adapter
• Supported materials: Plywood, MDF, solid wood, acrylic, carbon materials, aluminum, copper, stainless steel (with appropriate bits and feeds)
• Modules & accessories: Optional 500 W/800 W spindle kits, 4th-axis rotary, dust extraction, and laser modules.

Strengths

• More working area: Compared with the 4040 Reno, the TTC 450 Pro adds 60 mm in both X and Y, giving noticeably more space for trays, drawer fronts, cutting boards, signage and multi-part jobs.
• Stiffer, more durable frame: The mix of sheet metal side plates, aluminum profiles and larger motors provides improved rigidity and stability during cutting, which is especially helpful with deeper passes or longer jobs.
• Touchscreen and smarter control: The integrated 3.5" touchscreen makes it easy to adjust settings, run jobs from TF card, and switch between spindle and laser modes without needing a PC tethered full-time.
• Clear upgrade path: Bundles are available with 500 W or 800 W spindles, 4th-axis, laser modules and dust extraction, so the same machine can grow from hobby use into serious small-business production.
• Material versatility: With the right tooling and upgraded spindle, the TTC 450 Pro can move beyond basic wood and acrylic into aluminum and other soft metals, opening up more product and fixture ideas.

Considerations

• Needs a bit more space: The larger frame does take up more bench depth and height, so you’ll want a stable table or dedicated CNC bench.
• Best with upgrades: The stock 775 motor is good for lighter work; to get the most out of the machine’s rigidity, the 500 W or 800 W spindle upgrade is recommended for frequent cutting of hardwoods or metals.

If you’re planning to do more than basic hobby projects — or you want a CNC that won’t feel limiting in a year — the TTC 450 Pro is designed as a more future-proof platform.

Key Feature Comparison

1. Work Area & Project Size

The most obvious difference is working area: 400 × 400 mm on the 4040 Reno vs 460 × 460 mm on the TTC 450 Pro. That extra 60 mm in both directions doesn’t sound huge on paper, but in practice it often means:

• Fitting a full-size cutting board or serving tray in one setup.
• Nesting more small parts per sheet of material.
• Less re-clamping or tiling for signs and panels.

If your projects are mostly coasters, tags and small plaques, the 4040 Reno is sufficient. If you want room to experiment — charcuterie boards, drawer fronts, multi-part fixtures — the TTC 450 Pro’s extra area is a real advantage.

2. Rigidity & Accuracy

Both machines are built around metal frames and lead screws, but the TTC 450 Pro uses heavier sheet-metal side plates and a larger, more rigid structure. The 4040 Reno publishes a running accuracy of ±0.1 mm, while the TTC 450 Pro specifies engraving accuracy at 100 ± 0.05 mm.

In practical terms, both are accurate enough for small woodworking projects. The TTC 450 Pro’s stiffer frame and tighter published accuracy give it an edge for:

• Fine inlays and joinery where fit matters.
• Longer jobs where deflection or racking can show up as taper.
• Cutting metals or tougher plastics where forces are higher.

3. Spindle Power & Material Capability

Out of the box, the 4040 Reno ships with a 75 W spindle rated to about 9,000 RPM — fine for engraving and light cutting in wood and plastics, but limited when you try deeper cuts, hardwoods or metals.

The TTC 450 Pro starts with a 775 DC motor and is explicitly designed around easy upgrade paths to 500 W or 800 W spindles. That difference in available power and RPM headroom is a big deal if you want to:

• Cut hardwoods at reasonable feed rates.
• Mill aluminum or brass with proper chip loads.
• Run production batches without baby-sitting every pass.

4. Electronics, Control & Workflow

Both machines use modern 32-bit GRBL-based controllers, but the user experience is different:

• 4040 Reno: Controlled via PC or an offline pendant, with Wi-Fi support and app connectivity. Simple and familiar if you’ve used other Genmitsu machines.
• TTC 450 Pro: Adds a 3.5" color touchscreen on the machine itself, TF card/USB/Wi-Fi, and straightforward switching between CNC and laser modes. You can store jobs on card and run them without keeping a computer connected.

If you like a minimal setup and hate juggling cables, the TTC 450 Pro’s integrated screen and offline features make daily use smoother.

5. Laser & 4th-Axis Options

Both platforms support laser modules and 4th-axis rotary attachments, but the TTC 450 Pro is explicitly marketed with bundles combining:

• CNC router + 500 W spindle + 4th axis.
• CNC router + 500 W spindle + TC-series laser module.

This makes it easier to buy one machine that can cover flat-bed routing, rotary work, and laser engraving without building your own ecosystem from scratch.

6. Assembly, Footprint & Noise

• 4040 Reno: Semi-assembled modules with a quoted assembly time of around 30 minutes. Its smaller footprint is an advantage in very tight spaces.
• TTC 450 Pro: Shipped “95% pre-assembled”, with many owners reporting they can be running within about 10 minutes. It is larger in all directions, so a sturdy bench is recommended.

For absolute minimal space, the 4040 Reno wins. For minimal fuss between unboxing and first cut, the TTC 450 Pro’s pre-assembly plus touchscreen make it feel more like a “plug-and-play” system.

Which CNC Router Should You Choose?

Choose the Genmitsu 4040 Reno if:

• You are brand-new to CNC and want to start simple.
• Your workshop space is very limited (small bench, apartment, shared space).
• Your projects are mainly small signs, coasters, jewelry, boxes and light engraving.
• You’re on a tight budget and don’t yet know how far you’ll take CNC.

Choose the TwoTrees TTC 450 Pro if:

• You want more working area for boards, trays, panels and nested parts.
• You care about rigidity and accuracy when cutting deeper or harder materials.
• You plan to upgrade to a stronger spindle, 4th axis, dust extraction or laser modules.
• You want a CNC that can grow with you from hobby projects into small-business production.
• You prefer a cleaner workflow with touchscreen control and offline job storage.

In short, the Genmitsu 4040 Reno is a capable entry-level 4 × 4 CNC router that makes sense if you’re space-constrained and just starting out. But if you want a machine that will still feel capable after your first dozen projects — with more room, more rigidity, and a clear upgrade path — the TwoTrees TTC 450 Pro is the smarter long-term choice.
