Jay Bates shared the woodworking insights and machine setup process featured in this video.
After finishing the build of his new large-format CNC router, Jay walks through the details that make the machine ready for real work. He covers everything from tool touch-off routines and machine specs to the control pendant, machine file setup, and spoilboard strategy, wrapping up with the very first job cut on the new table.

Tool Touch-Off Made Simple
One of the first upgrades Jay highlights is a tool touch-off plate designed to simplify bit changes. On his previous setup, he had to reset his Z-zero every single time he swapped bits, whether that zero was referenced off the machine bed or the material surface.
With the new plate, that process only has to happen once. After the initial zero is set, changing bits simply requires a quick touch-off on the plate, and the machine automatically calculates the difference in bit length compared to the last tool used.
This kind of system becomes especially valuable for anyone running multiple bits in a single job or eventually adding an automatic tool changer, since it removes a repetitive and error-prone step from the workflow.
Machine Specs and Motor Options
Jay breaks down the real-world travel of his new machine, noting that while it’s marketed with a certain footprint, actual usable travel ends up being a bit more in both directions once sensor and software tweaks are accounted for. However, he’s quick to point out that not all of that extra travel is truly usable, since some of it sits above the side rails where clamping isn’t practical.
He also discusses the motor options available for this class of machine, ranging from standard stepper motors to the servo motors installed on his build. The key difference is that servo motors operate on a closed-loop system, meaning the machine constantly verifies its actual position rather than simply trusting that a command was executed correctly.
While stepper motors have served him well on past machines, even under heavy use flattening slabs and epoxy tables, the servo setup offers more power, quieter operation, and added peace of mind for anyone running demanding jobs.
The New Dust Shoe and Pneumatic Spindle
Dust collection gets a major upgrade in this build. Jay compares his new aluminum dust shoe to previous homemade and 3D-printed versions he’s used, noting that this one solves a problem he never fully cracked before: being able to quickly detach the shoe to clean the spoilboard mid-job without hunting down another hose.
The shoe also allows for easy bristle swaps and quick removal for bit access, all while staying solid and durable in daily use. Paired with a pneumatically controlled spindle that pops bits out with the push of a button, these small quality-of-life improvements add up to a noticeably smoother workflow.
Why the Control Pendant Changes Everything
Having run everything from industrial CNC routers to hobbyist machines, Jay says the new control pendant is one of the most useful additions he’s ever used. It allows nearly every function to be handled directly from the machine itself, without returning to the computer.
Features like feed hold allow a job to be paused instantly if something unexpected shows up in the cutting path, while the tool check button takes things a step further by lifting the spindle, stopping it completely, and allowing the operator to manually adjust anything nearby before resuming exactly where the cut left off.
The pendant also includes a customizable park position, which Jay sets near the front of the machine to speed up the homing process every time the machine is powered on. Adjustable jog speeds, including an extremely fine increment, make tasks like zeroing a large fly cutter far more precise without even needing a touch plate.
Building a Machine File for Long-Term Accuracy
Before diving into any real projects, Jay recommends creating what he calls a machine file, a saved template that records permanent reference points like the location of the rails, the spoilboard, and any repeated hole patterns used for workholding. He stresses saving incremental versions of this file so that a corrupted or altered file never wipes out critical reference data.
To locate the rails accurately, Jay uses a precision rod to sight in the exact edges of the machine structure, then accounts for bit radius when translating those positions into the software. The same method is used to align the spoilboard itself, ensuring everything cut into it lines up perfectly with the machine’s true axis of travel.
Having this information saved permanently means future jobs can reference a known origin point instead of resetting zero every time, which saves time and reduces the chance of costly mistakes.
Spoilboard Strategy for a Large Machine
With so much surface area to work with, Jay outlines a zoned approach to his spoilboard layout. One section is dedicated to standard sheet goods, another wide open section is reserved for long beams and slab work, and a separate area will eventually house a vertical table for additional operations.
For clamping large beams, Jay plans to rely on F-style clamps rather than small hold-down clamps, which aren’t practical for heavier stock. To support this, he’s designing removable segmented caps that sit flush with the main spoilboard height, allowing large flattening jobs to remain fully supported across the entire table.
He also discusses cost-saving alternatives to the expensive track and hardware he used on his last machine, aiming for a setup that’s both functional and more affordable for anyone following a similar path.
The First Job Off the New Machine
To wrap up the setup, Jay runs a small prototype project, a simple dished shelf with an integrated round-over detail. Despite its simple appearance, the piece required some thought to execute correctly, using offset vectors to create the pocket and a round-over bit to shape both edges cleanly.
After finalizing the design, several matching pieces were cut from red oak blanks, marking the first true production run on the new table. It’s a fitting way to close out the setup process, proving the machine, the tool changes, and the new spoilboard reference points all work together as intended.
Final Thoughts
This walkthrough offers a practical look at everything that goes into getting a large CNC machine ready for real work, well beyond just bolting it together. From tool touch-off systems and motor choices to control pendant features and long-term spoilboard planning, Jay’s approach highlights how thoughtful setup pays off in accuracy and efficiency down the line.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
Matt’s Take: Watching Jay go through this whole setup is a good reminder that with a CNC, the machine purchase is really just step one. The tool touch-off plate is a great example of a small addition that pays off way more than its size suggests. If you’re running a machine without one, it’s worth adding to your own setup at some point, especially once you start using more than one or two bits per job. That repeated Z-zero reset is where a lot of mistakes creep in, usually from rushing through it after the tenth bit change of the day.
On the stepper vs servo motor discussion, that’s a real consideration for anyone shopping for a machine in this class. Steppers are perfectly capable for a huge range of work, but closed-loop servo systems give you that extra confidence on heavy cuts where a missed step could ruin material or, worse, cause a bit to bind unexpectedly. If you’re running dense hardwoods or thick slabs regularly, it’s worth factoring into your decision.
The machine file concept is something every CNC owner should take seriously, regardless of table size. Losing your reference points because of a corrupted file or an accidental overwrite is a frustrating way to lose a day of production. Saving incremental versions costs nothing and can save you hours down the road.
Lastly, dust collection setups like this aluminum shoe highlight something people underestimate until they’re mid-job with chips everywhere. A shoe that’s quick to remove for cleaning or bit access makes a bigger difference in daily use than most beginners expect.
