Jim: Probably someone else has responded to this question already, but here's MY 2? worth: A resistor is NOT like a semiconductor or battery, anymore than a piece of wire with bits of paint on it! It

Hi, On Steve's page, you will find a link (outdated) to my version of his program and interface. I have made some changes to the interface and minor modifications to the program. The program was then

As with most things in the real world, it just isn't critical that the tool be perfectly oriented for every cut. On a manual lathe you are always confronted with a cutting operation that requires

A tool with a round insert on it works fine.

the available to constantly Sorry - I should have referred to why I thought this was the case. I found this on another machining group:

Joe, I put a Windows DRO program in the files section a while back that uses that DRO board, You can try that if your computer will do windows. It is called VB_DRO or something like that. I just wrote

I too was eyeing the MT3 version of the spindle. Problem is at $35 and 5 days left on the auction - you might as well buy it new. I went to little machines:

Rotating tool bits? That's a new one on me at the moment. I can see the sense behind it but I've not seen one that can actually do that available to the hobbyist. My CNC lathe cuts spheres and tapers

I ran my Shoptask with some 260 in/oz motors for a while and it worked, but the feeds were what I would consider marginal. The Z actually requires a pretty stout motor. You do not the reduction

Another question for everybody. And for this question I need to clarify that I'm NOT a machining wiz - in fact I don't even have my own lathe yet. If a lathe is converted to CNC, I thought that it

I'm planning to CNC my shopmaster when it arrives as well as a mill/drill I picked up. In my parts bin I have a few double stack Nema 23's which are supposedly 100 ozin, 1 triple stack 23 which is 150

You did real well down to here .. it is the aim of all grinders to make the flutes equal, to prevent the drill cutting ovesize. That is also part and parcel of all instructional materials on drill

A mouse is not really a good way to do DRO, as the computer can miss a count and not bat an eye. Here's a better solution (but more expensive): http://www.lindsayengraving.com/other_interests/dro.html

I have built this interface and tested it with both 500 line and 1000 line encoders. It works great and really does not cost much to build, IIRC less than $10 including a box to put it in, screw

I just received an e-mail with the following subject: gcodeTESTFILE This message came personally, and not through this list. But obviously from somebody's computer on this list. Check your sent mail

Hi Tim, Ground the center tap, and use a pair of diodes from the ends to the cap. You could probably use 1/2 a bridge, also. Alan KM6VV Tim Goldstein wrote:
