I believe I have the answer to this question, as given to me verbally. These two drivers cannot be electrically identical. The G213v is not a direct replacement for the G203v, despite containing a...

My current build utilizes a Pico Universal Stepper Controller. This device provides it's own step timing and Pico Systems tell me I will have problems using their device with a Gecko G213v due to...

I'd like to get hold of 4 x 23-305-DS8A steppers but the HobbyCNC web site will only allow me to order if I create a PayPal account and agree to PayPal terms. That's not going to happen.

Thank you, John. I will join the IRC channels once I get a client installed and figure out how to do it. :D




I don't expect latency or speed to be an issue. The system doesn't 'run' off...

I don't have a CNC device and I've never used EMC. I'm completely new but I've been following EMC and a few CNC router projects for about two years and am on the cusp of starting an EMC2 based CNC...

Ditto. :)

I'd like to put together a quarter sheet router. Ultimately, it would have a cutting area just a tiny bit larger than 24" x 48". I'd like 3" of Z travel too.

What are the options?

I'm looking to build a 2' x 4' machine. Basically, a 1/4 sheet router.

The project isn't expected to start for another couple of months.

Should I look at scaling down a 4x4 or go with the 2006...

I can't wait to see more on this project and perhaps plans. I used to be a sheet metal worker and still have access to a shop.

The more I think about this design, the more I think galvanized...

I checked out the Mike Beck kit. It looks good.

From his description, "Lead-screws are not included. A complete set of Kerk Motion PRECISION lead screws and self compensating anti backlash nuts,...

I don't understand the idea of using a Dremel tool in a platform of this precision. Won't the Dremel seriously hamper the precision of the table? Perhaps the sideplay is much better than the...

How much Z-axis amplitude do you suppose is reasonable? I've been looking at 48"x24"x6" as a goal but the more I think about it, the more I wonder if I will ever use more than 2" of z-axis. I'm...

I've been gone for a few months so I apologize for this question.

What happened to the 2006 r-2? I can't find references to it anywhere.

The pics all look like 1/2" material on the Z carriage...

Depending on how deep your defects are, you might do well with a spray type polyester filler/primer. From there, you're ready for a quick sand and paint. Polyester products stick great to Al and...

There are a couple of things I wish to comment on. I apologize in advance for being contradictory. I just think a couple of philosophical items could use another view to enhance the objectivity.

You rock, Ito-brazil. Thanks. I look forward t otrying it. :cool:

I need a pump for my Babington burner. Is a low volume oil burner pump the way to go? It seems like most pumps are 150 GPH and up but there's no way my globe will be able to take a 2+ gallon per...

Thank you very much. :)

I wish to build a foundry, based on a Babington burner. It will be for Al only. Is there an obvious choice of thermal couple to monitor melt temperature? Is there an infrared device that can do...

I'm kicking around the idea of using 1" galvanized conduit, instead of gas pipe in a Joe2000che clone router.

It seems to me that it would be just as good material choice, given that it will be...

I wouldn't.

He's working on a 4x8 design right now.

If you need a 4x8 machine that is pre-built, perhaps you should consider a ShopBot.

He has a thread, here.

He has a design that looks like this:

He has a kit that looks like this:

If I wanted a fast build, economical, great machine, I'd buy a full kit from Joe2000che. For 1/4 sheet wood working, I don't see how you could beat it.

I have no doubt he would ship it to you...

You rock! Thank you very much. :)

Air cooled is even smarter. :cool:

Does anyone have some experience with converting part of a small multi-cylinder engine to air compressor duty?

I'm thinking of something like a 4 cylinder motorcycle engine or maybe a small car...

I have an assortment of questions regarding fixed lead screw and rotating lead nut configurations.

Everyone seems to use timing belts on lead screws. My local Harbor Freight type store (Princess...

That's why the skate bearing solution is so compelling. You can use tubing and support it across the whole span.

Has anyone tried to recycle one for use in a CNC device?

The goal speed will be for rapid movement, not cutting.

The router dimensions will be 48"x24"x6"

How fast can I turn a 54" long 1/2" lead screw before it starts whipping? I have arbitrarily chosen 100 IPM as a goal speed. I'm guessing I'll need to turn it much slower than the 500 RPM that this...
