Environmentalism in all its forms is nothing more than a facade for totalitarianism. The modern politic has found it all too easy to create mindless supplicants through the use of cute and fuzzy...

Unless you are talking about a dedicated system, running its own hardware and software, you are simply not going to see your "closed loop sytem". Modern servo controllers and systems run their...

Titanium is a very strong material, but it doesn't hold an edge worth a damn. You are far better using one of the new super alloy steels, like CPM 30V. They are easier to work with than Ti, and are...

Mariss has always been MORE than helpful to me when I have called him with a question- many times the same question I had simply forgotten the answer he had previously given me. His company will...

The laser diodes used in laser printers are FAR too low powered to do any kind of direct marking/ engraving. There are VERY powerful laser diodes available, in a variety of wavelengths, but they are...

Geez… Pretty big machines we're talking about here. Have you thought about one of the new inverter type machines?

I've been using a Miller Dynasty 200 DX for about a year and a half now, and its...

I'm hoping my machine doesn't cause any problems… I've some rather "exotic" hardware on board. My machine is set up to run Maya, and the nVidia 7800 GTX video card has 512MB of VRAM alone. But,...

I was almost thinking about trying out that new USB based controller from Gecko, but I have ZERO programming experience. I'll probably grab an older machine from one of my freinds to run Mach, at...

It looks as if I'm going to be running My BCC on my big Power Macintosh workstation, and picking up a new(ish) Dell to run out in the garage on Mach 3. That, or build something with a cheap...

Do you think I'd be able to run the BCC on my Mac then? The salesman at Bobcad said he had seen clients doing that, but beyond that, he had nothing else to offer. I'd much rather have the design...

Well, I finally took the plunge and bought BCC V21. I now have to decide what to do about my host computer. I do not currently own a Windows machine, I have always used Mac. My question is, would...

If you're cutting thin guage ferrous materials, just get the Fine Cut kit. That, and a partially submerged sheet of material (just a few mm of water over the surface) will work wonders when cutting...

I just looked at your steppers as well, and judging by their appearance, they are a bit older style slo syn motors. I do not know exactly why this is, but the round body motors are said to be no...

I haven't used the cutmaster plasma, but the Hypertherm seems to be the weapon of choice for cnc applications. Thermacut also makes silver enhanced consumables available for the hypertherm MAX...

The hydrogen gas buildup under workpieces occurs when cutting partially submerged work on a water table. It is a result of stray electrical current, and hot metal hitting water, dissociating...

Thanks for the link to the article, Big Woody. From what I can see, there is no reason the HD torch cannot be utilized with a conventional power source. The full benefits of the system may not be...

I have been looking at the Hypertherm plasmas for my CNC gantry type machine, and have settled on a Powermax 1000 for the task. Beyond that power level, my electric wont support the larger machines,...

You will probably find it relatively impossible to weld aluminum. Even with a proper TIG setup it requires a fair amount of time to get the technique down, and consistency even longer. I would...

I can't see any reason why it coulpn't be used, and I'm surprised I haven't seen anyone else mention it. This system is used in manual analog radio tuners as well, and it maintains perfect accuracy...

I'm using ballscrews all the way round. I have three precision ground screws, the X is a 1.25 inch diameter screw so I'll be setting that one up as a rotating nut system. This machine could go...

Servos really don't make sense until you get into high power requirements. I use 720 oz./in steppers, and with my ballscrews, they generate over 750Lb of linear force! Servos make sense if you are...

Many of the medical lasers you will find today are Nd:YAG. They have a wavelength of around 1054nm, and do use fiber optic light guides. They are typically pulse lasers, and are typically more...

The problem is that pressure washers and flowjets are two completely different animals. Pressure washers are looking to generate just enough force at the work surface to lightly abrade it, and...

The Dynasty is FAR from being a toy. Having used every Miller from the 180 SD to the Aerowave, I can tell you the Dynastys are far and away the best welder Miller makes for the money. It may seem...

Don't bother using the pressure washer. A better way to look at waterjet power is in terms of Horsepower. Even the smaller machines are rated at 25HP and above. Pressure washers simply don't have...

How tight a tolerance can I expect from a conventional machine torch on a gantry type machine? I'm talking about a good quality, entry level Hypertherm plasma machine, running a machine torch, and a...

Good evening, everyone. I am currently building a CNC router type milling machine, and am wondering about reconditioning my OLD Index mill. This thing was built around 1928, and has seen better...

The moving mass of the system is quite critical for any machine that needs to change directions quickly. Though I've had to shave my need for speed somewhat, I will be keeping my moving mass to a...

Has anyone here used both DC servos and steppers on a project? I'm considering using a large servo motor on my X axis, so that I can run my heavier screw, and steppers on my Y and Z. I'm concerned...

Drk: I have found, and purchased, the Danfoss you mentioned. Can you tell me how you have yours set up? I'd like the speed to be controllable by my software, and I know the 2800 has 1-10V signal...
