How to level the table of a cnc router?

Jul 01, 2025

Hey there, fellow CNC enthusiasts! I'm a supplier of CNC routers, and today I'm gonna share with you how to level the table of a CNC router. It might seem like a small detail, but trust me, a level table can make a world of difference in your CNC projects.

First off, why is it so important to level the table? Well, if your table isn't level, it can lead to all sorts of problems. Your cuts might not be as precise as you'd like, and you could end up with uneven surfaces on your workpiece. This can be a real pain, especially if you're working on a high - end project where precision is key.

Let's start with the tools you'll need. You're gonna need a good quality spirit level. It doesn't have to be super expensive, but make sure it's accurate. You'll also need some shims. These are thin pieces of material that you can use to adjust the height of different parts of the table. And of course, you'll need a wrench or a screwdriver to make any necessary adjustments to the table's support legs.

The first step is to clean the table. You want to make sure there's no debris or dust on the surface. Even a tiny piece of dirt can throw off your leveling. So, grab a clean cloth and give the table a good wipe down.

Once the table is clean, place the spirit level on it. Start by placing it in the middle of the table. Check if the bubble in the level is centered. If it's not, that means the table isn't level. Now, move the level to different areas of the table - the corners and the edges. This will give you a better idea of where the table is high or low.

If you find that one corner of the table is low, you'll need to use the shims. Place the shims under the leg at the low corner. Start with a thin shim and check the level again. Keep adding or removing shims until the bubble in the spirit level is centered. It might take a few tries to get it just right, but be patient.

For some CNC routers, you can adjust the height of the legs directly. Use your wrench or screwdriver to loosen the nuts or screws on the legs. Then, turn the leg to raise or lower it. After making an adjustment, check the level again. Once you're satisfied with the level in one area, move on to the next.

It's also a good idea to check the level of the table regularly. Over time, the table can shift, especially if you're moving your CNC router around or if it's in a place where there's a lot of vibration.

Now, I know some of you might be thinking, "Is there an easier way?" Well, there are some advanced CNC routers that come with automatic leveling systems. These systems use sensors to detect the unevenness of the table and make the necessary adjustments. But if you don't have one of these fancy routers, the manual method I just described works just fine.

When you're leveling the table, it's important to work slowly and methodically. Don't rush through the process. And remember, a well - leveled table will improve the quality of your cuts and the overall performance of your CNC router.
