Today we aim to explore the limits of this CNC machine by installing the A axis .

The 4th (A) axis is the rotary axis along the x axis which allow the stock material to spins while using the spindle ,so it can be more efficient and save time while dealing with more complicated operations

We utilised the pre-installed wizard  to do some crafting work.We use “spline and gears”  that makes cylinder into splines and gear.

We didn't have a cylinder, we took a piece of wood and took off the edges of one end so that blunt and can fit snuggly on the teeth of the tooth pulley.
Once we positioned it and fixated onto the mount, we attempted to make a spline out of this piece of wood.once we put in the appropriate parameter , we start running the gcode.
During the milling, it started smoking due to the volume of friction.we had our fingers on the emergency button as we're prepared to turn it off if anything goes wrong.
At the end, we ended up getting a ridge carved instead as in the ideal setting, it was supposed to be a cylinder.
We did get the A axis moving which is good as we have encountered problem on every component of this machine, making sure everything is running smoothly.We had problems fastening and loosening the teeth on the tooth pulley this morning.the teeth fell out while we were attempting to mount the piece of wood on the pulley.There were no instructions on how to put the teeth back on.we spent the next hour trying to put the teeth back .

We have had problem with the motors, the spindle, the engraving tips, the A axis teeth pulley, the USB controller board(The motor for A axis overheated and blew the fuse inside the USB control box ), the software.
The quality of this CNC router is not best and questionable.it serves its purpose and are able to do whatever you tell it to. However, after 5 weeks of using it, I would only recommend this machine to someone who has experience with machining and controlling the operating software, someone who knows what they want and how to do it.

The manufacturer of the machine can be important when considering buying a CNC machine as in the future there may be a need for their help and support as someone who has never had experience with these type of machine. the manufacturer of the CNC machine is from China.it was hard to get a hold of them due to being in different time zone.It would be more convenient for us if we can have customer support on the mechanism of the CNC router in our normal office hours.

Investigation

Now we have to investigate the relating methods and topics that possibly help us find a solution. The goal is to find the most efficient way to bring low volume, accurate, fast turn around manufacturing in house. 4 axis CNC Milling/Routing: CNC stands for Computer numerical control. Numerical control is the automated control of machining tools and 3D printers by means of a computer. An NC machine alters a blank piece of material (plastic or thermoformed plastic ) to meet precise specifications by following programmed instructions and without a manual operator. Computer Numerical Control is different from typical PCs in the type of software used to control the machine, which is specially customized and programmed with G-Code — a specific CNC machine language that allows precise control of features like speed, location, coordination and feed rate. A 4-axis CNC machine operates on the X,Y and Z axes like a 3-axis machine, but it also includes rotation around the X-axis, whi...

2nd week

CAM mach3 has a cam software called lazycam so we will be using it to be able to make the Gcode for the Mach3. CNC machine software Mach3 and Mach4 software will be used to run the CNC Machine, also a CNC usb controller software comes with the usb that could also possibly work into the making a router. Design of router: The design of router will be based with autocad, due that was the advised software to use but later on, we will do a research about it Errors we countered and how did we solve the problems: We did the building and fixing of the new CNC machine CNC machine not having a manual, search online and to contact seller No CNC calibration manual, search online and to contact seller Broken Mill needles, the solution will be to buy more Milling needles

Types of CNC used

5 different types of CNC softwares have been used: Mach3, Mach4, USB CNC Controller and PlanetCNC Mach3 Mach3 CNC Controller software will convert your PC into a fully functional 6 axis CNC Controller. Mach3 is one of the most popular CNC Controllers for both DIY and Industrial machines. Mach3 works on most Windows PC’s to control the motion of motors (stepper & servo) by processing G-Code. Mach3 is a feature rich program which is also easy to use. It works with other programs and will import DXF files, generate G-Code, fully customizable. Works with CNC Routers, Milling Machines, Lathes, Plasma Cutters and Lasers. Mach4 Mach4 is completely new software with less than 1% of the programming code in common with Mach3. It was written from the ground up to be expandable, flexible, and extremely responsive for use with very large files. Mach3 was designed for simple hobby machines and still serves this purpose well.  When quality, speed, and the ability to use or le...
