What is the Beagle camera?/First time using?

The Beagle camera is a dual-use camera that allows you to monitor and control your 3D printer remotely, while also making it easy to create time-lapse videos. 


For the first use, you can refer to the unpacking videooperation, which will complete the configuration and start printing faster.

What's the maximum storage of the TF card I can use for this camera?

The maximum storage is 128GB.

How to connect the camera to WiFi network?

1. Install the Beagleprint app on your phone

What's the camera lens? And what's the distance?

The beagle camera is using the fixed lens, and the focus distance is 20cm.

How can I connect the Beagle camera to the printer?

We provide the default micro USB to USB cable inbox to connect to the printer, if your printer is using a Hi-speeding 2.0 socket, you have to purchase one Hi-speeding 2.0 to USB cable.

Plug the USB side cable into the USB socket on the back panel of the camera, and the micro USB is plugged into the printer. After the camera is connected to the WiFi, then click to run the app Bealgeprint and click the "Connect" button under the camera review window. Before connecting to the printer, you need to select the brand and model of printer to confirm the printed size. 

What's the best position of camera to watch the printing?

It depends on your review angle and model height. If you just want to monitor the model printing, we suggest you can install the camera at the right/left of the printer; but if you want to make a time-lapse video of the printing, we suggest the camera position is at the high front side of the printer or on the top of the printer. And we have designed three brackets for your reference, all of them are designed based on Creality Ender 3 / Pro / V2 3d printer. You can download them from Thingiverse.com.

How shall I use the Beagleprint app?

The Beagleprint is an application with an easy and clean interface to watch the real-time video of your 3d printing and monitor your 3d printer status. With Beagleprint, you would auto-generate pretty cool time-lapse videos without any settings. 

How many cameras or printers could I manage through the Bealgeprint?

In theory, there's no limit to adding cameras into the app to control numerous printers, but if the number is beyond 30 units, it will occupy a lot of the resources of GPU in your mobile phone. 

How shall I delete the camera in the app?

In the device list, you select the camera which you want to delete and hold for 3 seconds, there's a delete dialogue to pop up to confirm if you want to delete the camera. After selecting "Yes", then the camera will be deleted. 

What brand of 3d printers does Beagleprint support?

The Beagle camera is supporting Marlin 3d printers with default baud rate of 115200, such as Creality Ender 3 / Pro / V2 / Max, Ender 5 / Pro / Plus; Anycubic Mega SE / Zero 2.0, Vyper; Voxelab Aquila / C2 / X2; Longer LK4 / Pro, LK5 Pro; Prusa MINI / MINI3S+...Please reach this article to check if the 3d printers list is supported. ---> "3D printers list is on supported in Beagleprint"

And the 250000 baud rate has been added to our camera Linux system, but we are still working on the communication between the camera and printer.

Settings_ cannot save settings

Possible reasons: high network delay

Solution: Try to change the network (network/mobile network connected to Camera)

Connect the printer_ the printer screen frozen/cannot start

Connection printer_prusa i3 MK3S+ cannot connect to

Possible reasons: The printer RPI PORT status is ON. After the port is started, the USB connection will be turned off and the GPIO pin is enabled

Solution: Find it in the knob screen and set it to OFF

Connect the printer_Inlap after the printer is connected (for example, Kobra Max)

Possible reasons: large electronic noise (motor/hot bed/large home appliances such as refrigerator), which affects serial communication

Solution: Use the USB cable/replace the printer's environment with the printer

Connection printer_inter cannot connect to

Possible reasons: The file suffix is ​​not supported

Solution: Update Camera firmware to V1.1.7, the new version supports more file suffix


Possible reasons: Camera Micro SD card is not installed/space is full/format is incorrect

Solution: The file is normal, and it will be transmitted to the Camera Micro SD card through the network. damage.

After printing _ start printing, cancel the printing or modify the hot end or the hot bed, and the heating state cannot be changed

Possible reasons: When the printer enters a temperature cycle, the serial communication enters a tunnel stage (a certain blocking state), and the command printer issued by Camera will not respond to it.

Solution: Update to the latest Camera firmware, such as V1.1.7, update the printer firmware, the newer Marlin firmware may support interruption and heating, thereby responding to other instructions

Printing_Error 4

Possible reasons: If it occurs in the automatic leveling process, it may be that the level of tone failure

Solution: This is determined by the printer firmware. Camera identification error stops printing. You can modify the G29 in Star Gcode, replace it with M420 S1

Printing_Error 12

Possible reasons: may heal failure or heat -sensitivity error

Solution: This is some abnormalities in the printer. Please check the printer, cable damage/sensor damage/power supply power/PID parameter

Printing_ print quality poor quality

Possible reasons: lapse photography mode (Clean Timelapse Video)

Solution: This mode produces a good delayed video effect, but due to some parameter settings, you may encounter bad printing quality. You can verify whether the printing quality is improved by turning off it.


Possible reasons: USB communication has a timeout

Solution: Printing serial port, there are certain requirements for serial communication rates. Using the USB cable only power supply will affect the communication effect, thereby generating timeout, packet loss, etc.

                  Printer firmware/motherboard influence: Some printer motherboards have different motherboard chips, which is also the influencing factor that causes unstable serial communication. The "Linear Advance" is opened in the printer firmware.

Printing_ print abnormal exercise/impact

Possible reasons: Incorrect printer settings lead to some mobile instruction executions, and impact occurred

Solution: Set the corresponding printer model. If you cannot find your own printer, you can customize the printer and set the correct surface size

Printing_ The height of the first floor is incorrect/non -adhesive/wear printing platform

Possible reasons: automatically level the printer, when printed in the serial port, the first floor compensation data may be missing

Solution: Modify the STAR GCode G28 in the slice software, a new line of "G29"/"M420 S1" below, thereby enabling compensation, re -slicing and generating GCode files, uploading and printing.

Timelapse_ not generated videos

Possible reasons: incompatible slicing software/not upload files and print/Camera Micro SD cards that have not been uploaded by Camera are not installed/space insufficient

Solution: Refer to the slice software used in the link check, if there are abnormal feedback to us (support@mintion.net), remember to attach the Gcode file, we will respond to you as soon as possible.
