5 Tips About Stepper Motor On CNC Wood Router

5 Tips About Stepper Motor On CNC Wood Router
1.  On cnc wood router, usually we call permanentmagnetsteppermotor, it is 2 phase, torque and volume is smaller, usually step angle is 7.5 or 15.
For 3-Phase VR step motor, it could realize big torque output;
 For another kind of stepper motor, called hybrid stepper motor, it adopts the advantage of PM and VR stepper motor, usually is with 2 phase and 5 phase. For 2 phase, the step angle is 1.8 and 5 phase's step angle is 0.72.
2. What is holding torque?
Holding torque means the torque of stator holding rotor when the steper motor does not turning. It is the most important parameter for stepper motor. Usually, stepper's moment of forcce is close to the torsional moment. A stepper's low speed torque will vary directly with current. How quickly the torque falls off at faster speeds depends on the winding inductance and the drive circuitry it is attached to, especially the driving voltage.
3. What is Detent Torque?
Synchronous electric motors using permanent magnets have a remnant position holding torque (called detent torque or cogging, and sometimes included in the specifications) when not driven electrically. Soft iron reluctance cores do not exhibit this behavior.
4. What is the precision of stepper motor?
Its precision is 3-5% of step angle.
5. What the surface temprature that steper motor can afford?
Better keep 80-90 centi degree. 
OMNI offer superior quality stepper motor on cnc wood router, it can afford 120 centi degree for surface temprature. This superior feature allow cnc router also be with superior working performance under high temprature, rather suitable for some summer in some region, such as Indian, UAE, Africa etc.

Misalignment Analysis For CNC Wood Router


Misalignment Analysis For CNC Wood Router

Misalignment Analysis For CNC Wood Router
It may occurs misalignment when cnc wood router works, there are several reasons may cause this problem,
1. Driving motor. Electronic devices and componets in the driving motor could cause misalignment appearance. If this appearance is not ofen, try to reduce the cnc router moving speed to see if still with disalignment. If always with disalignment, then have to fix or replace driving motor.
2. Voltage. CNC router requires higher power, if voltage is lower than noramally need, the lower power will cause disalignment, usually occursed on y axis. This may because of outsider voltage lower or there is with high power device on the same wire, such as electric welding. The solution is mounting on 5000w stabilized power supply with the tolerance less than 5%.
3. Interface board, mainboard, pinboard. If these boards are with problem, then cnc wood router one axis or three axis does not move, this will cause cnc router with disalignment.
4. Motor. If it is because of stepper motor or servo motor, then the machine will not move on certain direction, will not move even if you turn the ballscrew.
5. Machine body. Some spare parts loosen, impurity on surface also could cause disalignment. Take example, if shaft joint is loosen or broken, can cause disalignment, if no clean up or oil on guide and orbit, also could cause disalignment.
6. If the screening wire is broken, also could cause the problem. OMNI offer highrise screening wire.
The above is the main reasons cause cnc wood  router alignment. Any problem on cnc wood router, welcome send email to support@omni-cnc.com. And OMNI offer whole life guarantee on maintenance for cnc router, laser engraving machine, laser cutting machine, cnc plasma cutter.

Laser Engraving Machine&Laser Cutting Machine Maintenance
1. Feed into lube oil to linear guide on laser engraving machine and laser cutting machine. After using for a while on laser machine, the dust and fume could viciate linear guide. Turn off laser power, clean the linear guide with soft cloth, then feed into lube oil. Then move the axis to ensure oil get into the slider.Then mount on linear guide firslty, then mount on screw but no fixing. Keeping levelness, fix tape and slider, mount on lens, adjust the laser beam path on x direction.
2. Lens and Mirror Cleaness. After using for a while for laser engraving machine and laser cutting machine, the dust and fume will adhere to the lens and mirror surface. And this will affect laser engraving and cutting depth and accuracy. Usually per week, clean with absolute alcohol.
3. Feeding Oil To Bearing. For ensuring fine cutting and engraving result, some bearing need feeding oil regularly. Clean dust from bearing, feeding into oil by syringe needle slowly, and turn around bearing while feeding.
4. Belt Adjustment. If belt is too loose, the it cause overlapping appearance, if belt is too tight, then will cause belt wearing out. So after using for a while, please adjust the screw to belt to keep the belt with suitable level.
5. Laser Tube on laser engraving machine Maintenance. Suggest using distilled water to cool down laser tube. But after using for a perid, there will left limescale in the laser tube. T hen we could put some vinegar to take off limescale. Then clean the laser tube to last laser tube life.

Glass Engraving CNC Router Relief Sculpture Tips


Glass Engraving CNC Router Relief Sculpture Tips

People do relief sculpture on wood, stone, and also on glass. This is the reason we call cnc wood router,cnc stone router and cnc glass router.  Before people do this by hand, now with the development of technology, more and more shops engraving glass by cnc glass router for relief sculpture result.

OMNI give some tips when technician engraving glass for relief sculpture by cnc router. 
1. Considering glass is fragile, when we fix glass on the working table, should be careful and put PVC board or thin wood piece under clamping bar.

2. Before tool calibration, turn on spindle. When the spindle cutter is closing glass, using jog movement, every down distance is within 0.1mm.


3. About the home point on Z, better move spindle cutter to the center of whole glass, confirm the z home point at this position. In this way, the depth of engraving will be even.


4. After engraving glass by cnc router, glass powder should be clean in time by water.

Milan Furniture Fair 2012: Design Goes Digital CNC Wood Router


Milan Furniture Fair 2012: Design Goes Digital CNC Wood Router


Design is going through a digital revolution( cnc wood router laser cutting machine) with new materials and shapes created at the touch of a button, says Barbara Chandler.


The latest digital technology stole the show in Milan as the design world thronged to one of the world's most important furniture trade fairs, the Salone Internazionale del Mobile, now in its 51st year. The fair is accompanied by a mass of smaller events across the Italian city.


Internet-based "shared design" was the big buzz. It's the newest trend, according to Joseph Grima, editor-in-chief of the influential Italian magazine Domus, chatting live on the internet via the impressive pop-up studio of British webmag Dezeen.

Designers share their ideas by making them universally available via the internet (open-sourcing) where they can be used, improved or modified by other designers. Anyone can then download the plans for free, often including computerized templates that allow the item to be made locally using digital laser cutters, CNC routers or 3D printers. It's the new digital DIY.

Just how shared design can work was on show during a five-day event (hackedmilan.it) at Milan's major department store La Rinascente, where shoppers could witness the assembly of a "WikiHouse", designed by Architecture 00:/ of London.

To build a "WikiHouse" in a department store in Milan during the show week, volunteers downloaded component templates from the internet and had them cut in plywood by a digital wood cutter.


A team of volunteers downloaded digital templates for the building's plywood components, then had them cut locally on a digitally controlled woodworking machine( cnc wood router) before assembling the parts in the store. "Milan this year was more about ideas than products," says the event's organizer, Beatrice Galilee from Twickenham.


Elsewhere was Digital Forming's "co-design bar" — masterminded by Londoner Assa Ashuach — where you could adjust and customise designs to create your own version of, say, a lampshade or a pen, and then get it digitally manufactured and delivered to your home. This is a digital industrial revolution.

To Milan's transport museum, London's Tom Dixon brought two giant computer-controlled German metal punches to churn out flat metal shapes, which were bent into chairs and lights. Such machines can be programmed by teams of designers/developers working simultaneously in different countries. The resulting products can then be made anywhere, saving on transport costs and energy use by cnc wood router.

Tips of Cutting Aluminium


Choose What To Cut Aluminium

How to cut aluminum? By China CNC Router or waterjet? Sheet size would be 4' x 10' with a thickness of 1/4-1/2". Such aluminium is for fabricator, many companies use plastic and wood laminates. it would be a better investment for the company to buy a machine that could do multiple things as opposed to a water jet or china cnc router which will only cut steel and aluminum.

You can cut aluminum with a china cnc router. 


The China cnc router needs to be set up with lubricant spray and the vacuum pump cannot be one with graphite vanes - if the lubricant sucks through the vacuum to the pump and gets on the vanes, they are toast. 

Routers are not really made for cutting metals, however, the key word above is "can." For working metal, it is better to get a mill, as they are engineered for metal work in terms of feed rates, rotation speeds, adequate lubricant flow, recycling lubricant, etc. Hold downs are usually mechanical using t-channel (rather than vacuum, as is typical on  China CNC routers). Routers' rotation/hp ratio are typically best at higher rotational speeds (like 18,000 to 21,000 RPM), which are way higher than those normally used for metals.

What is G Code of CNC Wood Router


About CNC Wood Router G Code


CNC Router can read G code. 

Well, what is G code? General code is the programming language that CNC wood router read to cut a digitally created design into wood or another material.

 A basic code created by most computer-aided design and manufacturing software, G-code typically is written as a "g" followed by a two-digit code that indicates different aspects of the cutting job, such as cutting axis, motor speed or type of drilling. Similarly, M-codes are included in the programming language to operate external devices such as spindles or coolant systems, and to end the program.

What software can creat such G code? Many CAM software can do it. Such as type3, Artcam, Ucancam, UG, AlphaCAM etc.

What should I do after I get G code file? Please input it to cnc wood router machine control system, then the system could read it.
