KAVA Lite Auto Bed Leveling Sensor



"I didn't just buy a sensor. I bought their data, research and math" - Richard Dale 

"The only auto bed leveling sensor that pays for itself, over and over again" - Alex Williams

"Never again buying from rip offs on Aliexpress and Amazon" - Mel Linda

Are you having troubles leveling your 3D Printer's heated bed? Well, you're not alone. 

At KAY3D Labs, we too, had our frustrating hair-pulling moments with heated beds that are badly warped, uneven and outright nasty that even hair spray wouldn't save our prints so we made the KAVA sensor.

The KAVA Lite sensor isn't just your ordinary capacitive sensor. KAVA is an automatic bed leveling sensor that does 4 things:

1. KAVA can measure the unevenness of your with a minimum accuracy of 0.02mm with a heated bed of 80 degrees celsius or 176 degrees Fahrenheit. Accuracies can go reach as high as 0.001mm if you don't print at a heated bed's temperature of 80 degrees.

2. KAVA probes FAST. You can expect 3x3 Grid points on a 235x235mm bed to be completed in 32 seconds or less

3. KAVA also takes over your Z limit switch and enable live-Z tuning without touching bolts and nuts. Want to change between glass, PEI sheet, Power coated sheet and then back to stock printing surface? KAVA can do all that for you. Just turn the knobs and perfect first layers all the time.

4. KAVA uses the probed data together with Marlin firmware to actively correct your bed's uneveness to give you the perfect first layer. 

Sounds simple? It actually is! KAVA is an industrial-proven sensor that we use day in and day out with our CoreXY machines because they've never fail us even on production levels.

What makes the KAVA sensor even cooler? It has adjustable distances. If you ever want to change the sensing distance of the KAVA sensor, just take the included screwdriver and turn. You can change them real quick and real easy!

With our version of Marlin, the Cheetah 5.0 makes installation of the KAVA sensor even simpler. Usually, it just takes 2 lines of code and the installation is complete. 

Not confident with editing the codes yourself? Just send us a mail after your order arrives and our dedicated firmware team will help you with the setting up instead. We're here for you every step of the way!

The KAVA Lite Sensor has more; Probing Speed & Accuracy

Did you know that if you slow down the probing speed of the first and second probe and in addition, turn off the heaters during probing(we know some other sensors configured this in the firmware), you can increase the accuracy of a probing sensor?

So why don't we slow down the probing to achieve 0.001mm Standard deviations? Well, because there is little to no real benefit even when your M48 tests report 0.001mm.

Here's why. At KAY3 Labs, our job is to ensure all the products we sell go through stringent, yet practical tests. How practical you ask? Having you wait as little as possible to have our sensor probe your entire bed. Time is money, some say. We started doing live tests while optimizing every nook and cranny of the probing speeds and cycles.

And because we did, the results are spectacular, the KAVA lite sensor can probe accurately and complete a 3x3 Grid full probe in 32 seconds. See math below:

In our tests, we constantly issue 20 probe counts for Marlin to measure the standard deviation. We can accurate observe that it takes about 60 seconds for a total of 20 probes.

Roughly, that translates to about 1 probe cycle taking about 3 seconds. Since multiple probing is turned on, that's 3 seconds for the sensor to move downback up, down a second down before moving up. 

Before we forget, Chloe, the prototype for our CoreXY Machines is responsible for checking all our probes before they leave the KAY3D Labs warehouse. Want to see her in action? Check either the live / past video to see Chloe in action!

Using the largest STD deviation of a M48 test that we've ever recorded with the KAVA lite sensor being exposed to a heated bed at 80 degrees, we can use the figure: 0.02mm. This figure may seem like a lot, but we'll help you do the math and finally explain why 0.001mm standard deviations are not as important as you think.

Assuming your first layer's height is 0.2mm with a maximum deviation of 0.02mm, we can calculate how much this deviation is going to affect your first layer.

0.02/0.2mm * 100% = 10.0%

This is the maximum amount of deviation you're going to get when KAVA helps to set down your first layer. In other words. it will only be 10% higher or lower with reference to a 0.2mm height.

If you take a ruler / vernier calliper and look at the 1mm mark, you can try to visualize this 0.02mm or 10.0% of 0.2mm. If you cannot accurately measure or visualize how much 0.02mm is, on a blown up ruler scale, your first layer probably won't show the deviation too. This is why the KAVA sensor probes at such speed in our tests. Slowing down probe speeds to get higher standard deviations won't accurately give you better prints. But it will take up more of your time.

Frequently Asked Questions:

What are Motherboard limitations of the KAVA sensor?

We intentionally left this at the top because KAVA sensor does have a single limitation. We don't recommend using KAVA sensor on 8 bit boards because of space constraints. However, if you use octoprint or send prints via USB, KAVA will fit onto your board with no issues.

What is KAVA integrated with? 

The KAVA sensor does not have native integrations except with Cheetah 5.0, because KAVA integrates with everbody as long as you're running the Marlin firmware.

What type of sensor is KAVA?

The KAVA sensor is classified as a proximity sensor. In our case, a proxitmity, capacitive sensor.

What is KAVA's accuracy?

KAVA's accuracy can range from 0.001 - 0.02 mm at operating heated bed temperatures (Ender 3 of 80 degrees celsius or 176 degrees fahrenheit ). Temperature (especially high ones) are known to cause fluctuations. If you're worried about fluctuations, read our technical explanation on why you shouldn't be worried.

How will temperatures affect the KAVA Sensor?

Using the largest STD deviation of a M8 test that we've measured with the KAVA sensor being exposed to a heated bed at 90 degrees, we can use the figure: 0.02mm. This figure may seem like a lot, but we'll help you do the math. 

Assuming your first layer's height is 0.2mm with a maximum deviation of 0.02mm, that only means: 

0.02/0.2mm * 100% = 10.0%

This is the maximum amount of deviation you're going to get when KAVA helps to set down your first layer. In other words. it will only be 9.5% higher or 9.5% lower with reference to a 0.2mm height.

If you take a ruler / vernier calliper and look at the 1mm mark, you can try to visualize this 0.02mm or 10.0% of 0.2mm. If you cant measure or visualize how much 0.02mm is on a blown up ruler scale, your first layer probably won't show the deviation too.

Does the KAVA sensor have shielded cables?

No, the KAVA sensor does not have shielded cables because it doesn't need it. Shielded cables add to additional manufacturing cost, with little to no added benefits when it comes to probing accuracies, especially with the data we have collected. Do you see P.I.N.D.A.S used in Prusa MK3 etc using shielded cables?

Is the KAVA Sensor a clone? 

The last thing KAY3D Labs will do is to clone someone else's sensor. It does not reflect our values, our service standards and most importantly, our brand. Copying is a serious offence and we do not take it lightly.

KAVA is proximity sensor that widely used in industrial applications that require significant and repeatable results. These are trialed and tested sensors that we've ported over to use in a 3D Printing space. The KAVA sensor is the same sensor that heavy industrial machines use day in and day out. 

Is the KAVA Sensor safe?

Every sensor goes through individual testing after they're manufactured and shipped to our Lab. This ensures they go through the highest standards of testing before they're shipped to you to ensure you don't get a lemon.
