G-Code And Experts

G-Code And ExpertsDo I need to be a G-Code Expert?In a word, no. You will probably need to know how to quickly scan your G-Code if you are having problems during your machining simulation. Other then that G-Code and a CNC program are throwaway programs for the most part. What do I mean by that? Let me explain.Lets look at a specific design. Lets say a 12 by 12 square. You build your model, run it through your CAM Software and create a CNC Program made up of G-Code instructions to your machine. Say tomorrow the job requirements change to a 24 by 24 square. Do you go into your G-Code line by line and change the code? Most people wouldnt. They would go back into their CAD or CAM program and scale the square up to 24 by 24. Then post-process the job again to get their new G-Code program.There are some people that would do this editing line by line because the design is simple. Now think of a complex shape and what scaling it up or down would entail.This would include massive changes to the G-Code and reviewing it line by line. We are talking thousands of lines here vs. going back and quickly scaling the model and spitting out some new G-Code. And that is why G-Code is throwaway. Use it over and over when you can, but dont fret over archiving it if something changes. It is much better to make a copy of the design (CAD File) in its original state and save that somewhere. That is much more useful.Post Processing? - Now you have me worried. With all the variations in G-Codes and M-Codes, how will I ever keep it straight?Dont worry about that. The CAM program you choose will have many Post Processors. Post Processors are like translators. They help the CAM Program spit out the right G-Codes for your specific machine. All you have to do is select the right Post Processor before you spit out the G-Code. That is simple.Most CAM programs have many machine specific post processors already loaded. All you do is go to the list of them and click on your machine to select it.If you build your own CNC Machine, there are generic post processors loaded for different types of machines. Usually you pick a generic one and modify it a bit with a little testing. You are making sure a move in the X-Axis positive direction really means what you want it to mean.Back in the good old days of Home CNC, everything was transferred on a disk. Now I have seen people include their Control Computers on their home computer network and transfer the files needed wirelessly. At a very minimum, get a good jump drive and transfer things back and forth that way.CNC has become a very popular hobby and more and more people are starting to hop on the band wagon of CNC. Its a fun hobby and easy to do from your very own home with just a little elbow grease and creative mind.

Choosing A Handheld GPS Unit

Choosing A Handheld GPS Unit

GPS Units used to be all the same. They were universal and somewhat bulky. However, as the need and demand for GPS technology has increased, the way GPS Units are made has changed significantly. Hikers, bikers, cross-country skiers, and all kinds of other individuals who travel across the wide, open country had a need for a GPS Unit that was easy to travel with, yet still worked in order to assist and prevent getting lost in unfamiliar locations.Some people may not use handheld GPS Units for such practical purposes. Some people just like to have them on hand. Handheld GPS Units can help in an emergency. Besides, they look nice and make life much easier whenever you are traveling to any location. It may be you just want to purchase your GPS for looks, and that is ok. Whatever your motivation is, you can find an excellent handheld GPS Unit to suit your every need.Adding a GPS to your Current Handheld DeviceDepending on the type of handheld device you have, you may be able to upgrade so GPS technology is included. They make GPS information available to PDAs and even laptops. However, you can also purchase a handheld device with GPS functionality if you do not have one already. This is convenient since your GPS Unit now has multiple capabilities and functions.For example, the GPS manufacturer Garmin makes several nice PDA models including the Garmin iQue M3 Pocket PC and GPS Navigator.Getting Around with "Handheld GPS" UnitsGetting around your town, city, or the country becomes easier with a handheld device. There are two main brands of handheld GPS Units. The first is Garmin and the second is Magellan. There are other, lesser-known brands, but these are the two major ones. These brands differ in functionality (Garmin uses WAAS), features, and capabilities.Depending on where you are, the reception from the satellites sending the location to your handheld GPS Unit may be better or worse. Mountains, skyscrapers, and trees can all obstruct the satellite signal from sending to the GPS unit. This is partly why multiple satellites are used for each receiver. Of course, this can also mean your map image and directions are not as accurate.The downside to Handheld GPS UnitsIf you live in, work in, or visit areas that do not allow for GPS signals to read correctly, then you may not want to waste your money on a handheld GPS Unit. However, most areas, even the busiest or most mountainous do allow for access in certain areas, so you will find this is often the least of your problems.Another potential problem you may find with handheld GPS Units is their size. If you want to use a PDA GPS Unit, expect the GPS to take up the bulk of space on your PDA. You can get PDAs with additional space such as the Garmin iQue M3 Bundle w/2gb memory card as opposed to the Garmin iQue M3 Bundle w/1gb memory card.Of course, you may decide that cutting corners on your PDA just is not worth it. You can keep your PDA with all of the programs you need. Then you can purchase a separate, handheld GPS Unit such as the Magellan eXplorist 500 le or the Garmin GPSMAP 60C.These systems, while smaller than the portable GPS Units, are easier to transport. However, sacrificing size can be a problem. Often, maps, voice functionality, and other common features of portable GPS Units are considered add-ons for handheld GPS Units. You may be able to purchase the best handheld GPS Unit with all of the add-ons already attached, such as the Garmin GPSMAP 60. However, you will have to add at least one thing on. You are going to have to decide if purchasing a handheld, for this reason, is worth it.The Benefits of Handheld GPS UnitsOf course, the benefits do outweigh the annoyances when using a handheld GPS Unit. Depending on why you need a GPS receiver you may find that handheld units suit you better than a portable unit does.There are many reasons you should buy a handheld GPS Unit. These reasons include: Easily upgradeable on a PDA Able to work with many add-ons offering additional options after you purchase it Easy to transport Excellent for situations when you get lost or emergencies such as broken down cars (when you need to go for help) Ability to transfer images & maps to and from laptops, PDAs, and moreUltimately, whether you choose a handheld GPS Unit or a portable GPS Unit is up to you. However, just make sure you choose based on your needs and you simply cannot go wrong.

Canon Lenses: Is It Worth Buying The Brand Name And Not The Cheaper Alternatives?

If you own a newer Canon SLR, you have several choices of lens brands that you can buy for your camera. In addition to buying Canon brand lenses that work with the automatic focus of modern Canons, you can buy lenses from third party vendors such as Sigma and Tamron, who make Canon-compatible lenses for less cost than Canon. After having spent a large amount of money on the camera body, you may be asking yourself if it is worth spending the extra bucks for the brand name lens as well. I am an amateur photographer, so am certainly no expert, but from the day that I bought my Canon SLR with its brand name lenses you could see a marked jump in improvement in my photo albums. It is like someone focused everything and turned on the lights! I recently switched to a digital Canon and gave my six-year-old film Canon to my mother. Her photos showed the same amazing improvement.Reasons to Buy the Canon LensI generally like to stick to matching brand names with brand names, and my research has shown that most people on the web agree that doing so with Canon lenses is worth it. The first reason for the popularity of this Canon lens is image quality. Canon lenses are well-corrected for distortion, and have excellent color fidelity and contrast. In addition, they are characterized by superior lens construction. Canon lenses are the choice of many imaging professionals the world over, whether those lenses are being used on EOS SLR cameras or on broadcast cameras.Canon Lens CriticsAs with any product, Canon lenses have their critics. For example, I found one person who felt that on the Canon lens the auto focus seemed slower than and not as decisive as the other lenses they had owned, especially in low light.Canon Lens Facts and BenefitsLenses are extremely complex and sensitive pieces of equipment in which a myriad of problems can occur. Canon lenses are adjusted through the camera body with no on-lens control. All modern Canon lenses focus with a motor in the lens, which may be one of the main reasons my mother and I got such great photos. If you are near-sighted, this is an especially nice feature since it is difficult to focus manually if you wear glasses.Used Canon LensesAnother great reason to invest in the higher priced Canon brand lens is that camera lenses tend to hold their monetary value over time, while camera bodies do not. I have bought both a used Canon lens and a new Canon lens for work and home and, frankly, I could not tell any difference other than the price.

Digital Cameras Are Small And Compact And Take Great Pictures

Digital photography is a booming business and is slowly going to take over the film camera market. Compact digital cameras are the most popular and common of the camera types. To get a better quality picture you need to increase the number of pixels, so the cameras with more mega pixels will have a sharper image. Underwater digital cameras are small and lightweight, and the quality is comparable to film if you go for the higher resolution shots. Digital pictures have improved dramatically, and are now incredibly clear. The main problem that most have is that after the picture is taken many people don't develop the pictures or don't have a a way to do it.How exactly does it differ from the traditional camera? Up to the point when the image is captured, the process is the same in both. When you release the shutter the mirror moves out of the way and the image is captured in the same way as any digital camera. Zooming in on a subject works by cropping some of the image out of the picture. The thing to remember is the higher the resolution, the more realistic the image is, matching closest what the actual image is. The image is then enlarged to fill the camera frame, by doing this you will loose the quality of the photograph. If an image is too bright or too dark you can re-take the image.Digital cameras are not that expensive today a 2 mega pixel camera can be had for less than $50. Also important to note is the memory capacity of the camera. In other words, how many pictures will the camera hold? Understanding a little bit about how pictures are recorded on a digital camera and then subsequently saved on a computer is critical but fairly simple even for a beginner. The key to getting the best possible digital pictures is to make sure the right camera is bought. Digital cameras are becoming more and more popular. Whether your pictures are good or bad it does not matter, with a digital camera you have full control.In burst mode the camera shoots a fast series of photos for as long as the shutter button is held down or until the camera's memory is full. In this mode the camera writes the photos to a temporary memory which is very fast but small. When the shutter button is released or the memory is full the camera starts the slow process of writing the photos to the flash memory. Memory is also a very important issue to consider. In terms of features it may not have any more than a simple point and shoot model. Picture quality is normally an improvement from the more basic cameras. The price of a digital camera printer is lowering whilst the quality is increasing. As far as image quality is concerned, there are a couple factors - picture resolution, presence of noise in the camera, dynamic range, and the color quality of the image. Depending on the camera purchased and the accuracy of the settings, the quality can rival and sometimes even surpass a regular 35mm camera. Basically, a mega pixel is capable of storing a million bits of information about a photo. Because the digital SLR cameras are more professional, they come with a hefty price tag.
