Paul: There are "Interpolator" units available that can increase the resolution of encoders and linear scales. These are electronic and usually available in 2,5 and 10 times the encoder resolution.

Hi Marv, I too would like to see the drawing. I can read acad R14 also. John Guenther Sterling, Virginia

Hi Marv, I'm not Phil but, if you don't mind, I would like to see your DWG. I am currently running a Sherline mill, but am building a data base for the next bigger and better if you know what I mean

Phil, You can see pictures of motor brackets, not with timing belts, but direct drive, at www.matronics.com/cnc2/ . I also have an AutoCad drawing that someone posted on the net, of a geared down

To all who replied to my questions; thank you very much. I really appreciate it. Cheers Marcus

I assume your talking woodruff keys .... just lay a pair of wire cutter jaws parallel to the shaft and squeeze down on the end of the key and push down on the handles ,,,, I would not suggest useing a

John, I thought about the tap and drill approach but this seemed like overkill for such a simple issue. Know I know this is a legitimate approach I may try that. I'll check out the photos. I like the

This is all correct. Another way to look at it is two coils which change their angle to one another. The resolver is sent a sine wave. The signal goes through the coils and comes back with some phase

Two ways to remove keys Phil. One is to tap on the end with a sharp chisel to force the key up and the other is to drill and tap it and insert a jack screw to extract it. Not knowing what type of mill

I'm starting to look at designing motor brackets for my mill conversion but have an issue. I'm trying to remove the key from the x and y screws but having no luck. Is there a trick to this ? I've

I'll try, altough Jon, could probaly do better. A resolver can be a transformer with a 2 or more phase primary. The secondary is inside the primary and is free to move, some are linear, and some are

Scot; I have been fiddling with poly concrete and come up with a fair pile of information. Much of this was posted about a year ago. Contact me off list if you have trouble locating those old posts.

a the they Brian, Was the machine base basicly a hollow form made of steel, or cast iron? What I'm trying to figure out is, if it would be possible to build a small machine base out of 1/2" thick

For those using or testing VectorCad and/or VectorCam, we have nearly completed our new Macro Tool Bar. This is a floating toolbar program that enables creation of keyboard macro scripts that interact

Hi Steve, I'm assuming you have VM 4.0? I'm still running 3.2 while my upgrade ships. Answers below: Steve Ross wrote: Yes, probably. In VM 3.2 I have "Create Machine Ops", Create Menu" and "Create

Hi All: Can any of you explain to me, the differences between resolvers and encoders. What is the implication for machine performance? Is a retrofit from resolvers to encoders a worthwhile effort?
