Add Laser Head on Kingroon KP3S 3D Printer

by Kingroon 3D on Jan 21, 2022
Add Laser Head on Kingroon KP3S 3D Printer

We will show you how to turn your Kingroon KP3S 3D printer into a powerful laser machine, so that you can switch its mode to carve things anytime. And it is quite easy, what you need to do is buying a laser and flashing a new firmware.

UPATES:

 

Firmware for Laser Head has an Asapter:

KP3S Laser/Printing Firmware(Latest Laser): https://drive.google.com/drive/folders/1FXrEcM8Q6tyRcApMIIMrbXgdN7budZvS?usp=share_link

KP3S Pro Laser/Printing Firmware(Latest Laser):https://drive.google.com/drive/folders/1_wpNrnxc9_LzTkukvv_MjlbDWRr8uLD8?usp=share_link

KP5M Laser/Printing Firmware(Latest Laser): https://drive.google.com/drive/folders/1Av-MM56KZ5qz2Bjl4UaJ69m9v7Wrh1Ib?usp=share_link

KP5L Laser/Printing Firmware(Latest Laser):https://drive.google.com/drive/folders/182quZv3-v8uNgcIfaTXc0nq873YCAdge?usp=share_link

Here is the 24V 1.6W laser head we use. 

Kingroon KP3S laser head

Step 1, Connect the Laser on the KP3S Mainboard

First, remove the bottom cover and disconnect the fan cable. 

Then you need to check the MCU of your Kingroon KP3S mainboard, see if it is STM32F103 or GD32F303. The firmware now only works for these two models. We will release a newer firmware compatible for all three MCUs.

Connect the laser cable to the HE1 port. You need to remove the white cap of the laser head cable. Don’t mix the negative (black cable) and positive (red cable). This port will be used to power and control the laser.

After that, settle the cables well, put the wrapper back and install the bottom cover. You are ready to proceed next step.

Step 2, Prepare Files

Go visit https://lasergrbl.com/download/ , download and install the software. Import the files you want to carve, set the right size then save the file.

The largest carving size is 150*180mm, just make sure your setting is right. You will get an “NC” file then.

Next, download Kingroon KP3S firmware for laser head. Unzip the file, put everything along with the NC file into your SD card. Check below photo, make sure all listed files are included.

Step 3, Flash Firmware and Install Laser Head

Put the SD card in your KP3S and power it up. The firmware will start to flash automatically. It will take some time. Once you see the interface, the update is finished.

After that, you will see “Laser mode” and “Print mode” in settings, they are switchable. Switch to “Laser mode”, click “Light on” to test the laser. It should start to shine with an unfocused light.

Then you can install the laser. Remove the print head cover, put screws trough the right-side holes, connect the laser on the right side, make sure the laser is slightly higher than the nozzle.

After that, install the print head cover back, tie the laser cable well.

Step 4,Carving

Now you are all set.  Put a protect board on the heat bed, adjust the print head height manually, aim the object you want to carve, then you can start to carve.

The “Laser mode” won’t auto home, that’s why you need to adjust the carving height and aim the object manually. So, the laser will start to carve from the point you aim, please make sure your file is in a right size and do a well measurement in case it carves over the area. Also, you will get a deeper result by lowing the height.

Here is the result we got. We carved a leaf.

Since the laser are dangerous, please keep it away from your children, wear a protective goggle while it’s carving. Also, if you want to record its carving, you may want to avoid long videos with your smart phone, the shinning lights might damage its COMS.

    I have a KP3S Pro printer, and I’ve been using firmware with BLTouch. Now I want to add a laser head. Will the automatic bed leveling function with BLTouch still work? If not , any firmware available ? Tks

    This manual needs an update. The laser kit product sold by Kingroom and its website does not match the kit shown in the manual . The kit currently being sold includes a “Laser Module” chip that needs to be demonstrated here. Please update the manual .
    I want to purchase the laser kit, but at the moment there are no reliable installation instructions in accordance with the items being sold.

    buy this kp3s 3.0 thinking of getting a good upgradeable machine…. kingroon has let customers down using a chip (407) that would never get updates as promised, more than 2 years waiting for the firmware upgrades that the 303 chips got.
