I have a fully working VDU unit complete,
Both x and a drives
Spindle power board,
Lower 24v power board.
Headstock complete

Would these be any use to anyone?

A few other bits (motors spindle motor, etc)

I’m after some more tool holders for the multifix tool post on my Orac.

Anyone got some going spare?

Thanks

I don’t think so, Reading the manual (and the associated literature on here) the Denford Orac works in diameter. The sample programs all show diameter readings, and the written samples are all in diameter. I’ve played today, and it’s fairly simple to set a program, running it in radius, but I’m conc...

Ok, bit of an update. I’ve measured everything and it is strange. If I write a simple program, and use RADIUS rather than DIAMETER (ie- for cutting an 18mm length, I program 9.0) Then, when I come to set the tool, I set both tool 0 and tool 1 (my cutting tool) to z0 and touch on the 20mm bar and put...

Thanks Pete. I am kinda guessing it’s something to do with the stepper out of sequence. It’s not a random difference, it’s exponential as the diameter gets larger, So for instance, if I set the tool at X0.0 then take a cut at 20mm using manual control, it’s perfect, But if I set it to do a series of...

Hi all, Have an orac, old one which work threw away because it kept blowing the breaker every time you switched it on. I managed to fish it out the skip and bought it home. Fixed the issue with the breaker blowing, by removing the car stereo tape player, and blowing all the rubbish out from inside. ...
