2.Electronics test:

Power in power source input port(12V-30V) or in USB port . Red LED light indicates power success.

In the case of normal transmission of the signal,the blue LED will lights up when the distance of obstacle and probe near 15mm. In addition, the color of the obstacle can not be black.

3.The requirements of the sensor installation:

  • Adjust the print platform to ensure the distance from the extrusion nozzle to work platforms in the park position is near the thickness of a sheet of paper in the parking position. And the extrusion nozzles will not touch the working platform at any point.

distance from the extrusion nozzle to work platforms in the park position is near the thickness of a sheet of paper in the parking position

 

  • The sensor is fixed to the vertical upper position of the printer nozzle and the distance from sensor probe to the extruder nozzle is near 10mm .

distance from sensor probe to the extruder nozzle is near 10mm

 

  • Ensure the sensor probe remain at work within the platform range.
  • The automatic adjustment range of the work platform is ± 2mm .

Now the hardware connection and installation is complete.

 

Step 3 : Download the Firmware and Upload Tools

 

PiBot 3D Printer Controller Board USB Driver Click Here for Download

The PiBot 3D Printer software have integrate the USB driver, if you have install the software,you don't need install the driver again.

PiBot 3D Printer Firmware Click Here for Download

Only need configure All parameter in one-page--”OnePageConfigure.h”.

Firmware Upload Tools Click Here for Download

Please use this version to upload your Firmware then you don't need to modifying anything.

 

Step 4 : Configure the Paremeter in "OnePageConfigure.h"

Now,unzip the files of firmware to a folder and find the file named OnePageConfigure,h.

Edit the parameters in this page which your just preparing above and save it. (Notepad++ recommended for editor tools)

Set the following 6 parameters:Probing point1(near the park position),Probing point2,Probing point3,distance of senser and extruder in X axis,distance of senser and extruder in Y axis .

Make sure the probing points within your build platform , and near the edge.

Step 5 : Upload the Firmware to The Controller Board

 

1. Unzip the three files to separately floder.

configure your firmware/unzip the three files to separately folder

 

2. Install the usb driver controller board USB driver then connect the controller board to the computer via USB wire

configure-your-firmware/pibot-3d-printer-controller-board-rev1.6-usb-driver

 

3. Check the COM number in Device Manager.

check the com number in device manager

 

4. Run the arduinoarduino.exe in the Upload tool folder and open the Pibot.ino which in the firmware folder.

open the pibot ino

 

5. Select the COM which you check in Device Manager.

select the com

 

6. Select the board model - Aduino Mega 2560 in the arduino.exe

select board model

 

7. Verify and upload the firmware to the board

verify upload firmware

 

Step 6 :Open the PiBot 3D Printer Software

Select PI-Single-Extruder-Zprobe or PIHeatBed-Single-Extruder-Zprobe according to your requirements in the Printer Settings.
