Clay Forming MSachine



Clay forming machine is a 4 axis CNC which designed with the motive of automating the process of forming clay, which will give this industry many advantages, the most important of which is accelerating the production process and increasing accuracy, in addition to the possibility of forming clay in ways that cannot be done by human hands . this machine did by 3 of fabacademy students This machine was designed, manufactured and programmed by the efforts of these students

3. Electronics part

this is the bill of material for electronics components from a local supplier

wiring

basically we have two separate systems, one for outer geometry and the other for inner geometry so we need two controllers (Arduino UNO) with shields and 4 stepper motor drivers.


to control the disk speed we use a DC motor driver and this driver is capable to deal with 27V 43A which is the best choice for our system because we have a 24V 8A DC motor so this driver will handle the starting current safely which is 4 to 8 times the normal current


so let's start with the inner and outer axis we connect the stepper motors to the X and Z axis and the stepper driver to the same place so but make sure that the stepper driver is connected with the right orientation otherwise it will damage ( match the enable pins to each other and all the pins will be matched by automatically )

then connect the power supply cables to the 12V power supply, repeat this process for the inner and outer axis


4. Programing

Based on the CAD we have 4 axis machine, 2 axes for inner geometry and 2 axes for outer geometry also we have a high-speed DC motor for the clay disk.

GRBL


in order to program this machine, we consider the inner axis is separated from the outer axis. the DC motor will be controlled by PWM and adjusted by a variable resistor to provide the proper speed as needed.


so let's start with the main firmware for the system we use GRBL firmware which is a no-compromise, high-performance, low-cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328.


to install GRBL go to this GitHub repository then download the ZIP file

then we have to extract the ZIP and go to Arduino IDE to add the GRBL library go to sketch>>include library >>add .ZIP library then chose the file that you extracted it with name grbl

now let's upload the firmware on Arduino Uno go to file>>examples>>grbl>>grbl upload

upload the firmware

UGS

to control the CNC shield we need a software that gives instructions to the motors and by sending the g-code line by line to the Arduino Uno, there are several we choose Universal Gcode Sender UGS because is a self-contained Java application that includes all external dependencies and can be used on most computers running Windows, MacOSX or Linux.

so go to download page and install the UGS based on your operating system

after file extracting go to the bin folder then start ugsplatform64.exe and the UGS will open up

now let's connect to the Arduino so select GRBL firmware then select the COM number for your Arduino and the baud rate must be 115200

if the Arduino connected you will see the following lines on the console
