Getting your CNC Router wasteboard perfectly level is one of those tasks that sounds simple but can make or break the quality of your cuts with your EasyRoute CNC Router. A flat wasteboard ensures your cut depths are consistent across the entire table, which is crucial for precision work. I’ve spent plenty of time tinkering with CNC Routers, and I can tell you that skipping this step—or doing it halfheartedly—will leave you frustrated with uneven results. Let’s walk through the process of levelling your wasteboard, from picking the right tools to fine-tuning your machine for top-notch performance.

Picking the Right Router Bit
Choosing a router bit for surfacing your wasteboard is where it all starts. With so many bits out there, it’s easy to get overwhelmed. A two-flute straight cutter is a solid choice—it leaves a clean finish, but the smaller step-over means it’s slower at removing material. A V-bit? Forget it. You’d be waiting forever to level a full table—maybe until 2030 if you’re feeling patient! A three-flute upcut spiral bit works well, but honestly, you don’t need to splurge on fancy bits. I’ve had great results with a basic 12mm endmill that costs around 130 rand (about £5 GBP). It’s affordable, effective, and perfect for anyone just starting out or looking to save a few quid without sacrificing quality.
Setting Up the Tool Path
Next, you’ll need to create a tool path file for the surfacing job. The file should match the size of your wasteboard—say, a standard MDF sheet at 2750mm by 1830mm—but make it slightly larger to let the bit run off the edges. This ensures you’re covering every inch of the surface. In your CNC software, select the pocketing profile and choose your 12mm endmill. Set the depth to take off about 1mm of material per pass. If your floor or machine is particularly uneven, you might need a second pass, but 1mm is a good starting point. Once you’ve calculated the tool path, save it with a simple name like “Level” for easy access. If you’re using an AM CNC router, you’re in luck—these machines often let you set this up directly on the interface, no external software required.
Getting the Machine Ready
Now it’s time to move to the CNC router itself. First, make sure the bit is touching the wasteboard surface. I like using a piece of paper for this: lower the bit slowly until it just grazes the paper, pinning it in place. Double-check to be sure, then set this as your Z-height coordinate. Shift the bit slightly off the edge of the wasteboard to ensure full coverage during surfacing. Load your tool path file (I usually pop in a USB and scroll to find it), select it, and hit play. It’s a satisfying moment when the machine starts humming and the surfacing begins.
Watching the Process Unfold
As the router works, it’ll start shaving off material. Don’t be surprised if you notice uneven spots—floors are rarely perfectly flat, and that affects your machine’s alignment. For example, I once found one side of a table was cutting 2.5mm deep while the other was only 1mm. Pause the machine now and then to check progress. You’ll see a smooth surface starting to form, though you might notice faint lines from the bit’s step-over (set to about 90% of the bit’s diameter). These lines are a clue that your spindle might need some tweaking for perfect precision.
Fine-Tuning for Perfection
If your cuts show a ramp—shallower on one side, deeper on the other—your spindle might be slightly tilted. This is common and fixable. On an AM.CO.ZA EasyRoute CNC Router (or most CNCs), you can adjust this by loosening the spindle’s mounting bolts. Check which way the spindle is leaning by looking at the cut depths. If one side’s too deep, you’ll need to shim the opposite side to level it out. I’ve used brass or steel shims for this, but even a piece of paper can work for a quick test. Make the adjustment, run another test cut, and check the results. It might take a couple of tries, but when it’s right, your cuts will be spot-on, and those pesky lines will disappear.
Turning Your CNC into a Precision Beast
A levelled wasteboard is the foundation for an EasyRoute CNC Router that cuts like a dream. After surfacing and fine-tuning the spindle, you’ll have a machine ready for high-precision projects. It’s not just about flattening the bed—it’s about setting yourself up for consistent, professional results every time. If you hit a snag, don’t sweat it. Companies like Machine Africa offer on-site support to help get your router dialled in.
Levelling a CNC wasteboard isn’t glamorous, but it’s a game-changer. With a cheap bit, a straightforward tool path, and some careful adjustments, you can transform your machine into a precision powerhouse. So grab that endmill, fire up your router, and get ready to make some flawless cuts.
