My ballscrews were a lot harder than my drills so I ground a small flat on the machined portion of the ballscrews.

Hope this helps.

Thanks for the suggestions Guys.

The person I most suspect of leaving these in my workshop (but I am not sure) manufactures specialist transformers and coils etc.
Hope this may be a clue.

Thanks SteinarN,

It does look like a spring but there is little springiness in the object - it is in fact extremely rigid.

If I knew what it was then it would be an ideal candidate for a competition.

159 people have viewed this topic so far and nobody knows what they are yet - I can't believe it. 

I found another one today. The collection is growing.  If only I could find a use for them - no suggestions please.

Ena is Enable it it either high (+5V) or low (0v) check with your board suppliers data sheet.
The stepper signals are either +V (whatever voltage they are being driven at) or 0V (alternating if being driven) it is a square wave.

Thanks Guys.

I keep wondering if the cooling system will be man enough for the job.

Show"N"Tell ( What you have made with your CNC machine.) / Re: Vinyl Cutting.

« on: October 22, 2009, 02:29:38 AM »

Thanks for the compliments Guys.

Nothing special is done to the cutting path - the important thing is the tip offset of the cutting knife (the smaller the better) and it's freedom of rotation. The 90 degree corner radius, which is produced by drag knifes, is only just perceptible and in many ways it is an advantage in so far as that the vinyl may otherwise easily tear at a sharp corner when weeding. For really small signage the very thin vinyl (used for RC model decals etc.) is superb.

Now that Winter is almost here I will try to increase the X file page on my website to cover more aspects (RSA encryption and factoring of large numbers).

btw. I think Gertrude is a mill (with rotary axis).
