This seems to be mainly for teachers, but might be of some help.

This is the introduction to milling that came with the Novamill, but might be for other Denford millers.
I hope it is of help.

Does the speed variation create a big vibration? If not just run it up and see what happens. If the machine is vibrating badley there may be more of an issue. We do not normally run the spindle slow other than for threading. I would normally run the spindle at max rpm or close to it. Hi Steve, Than...

Have you tried running it faster? There may be nothing wrong. I have ran it up to 600 rpm and still have the problem. Even without looknig at the speed on the monitor, it is quite clear it is fluctuating, from the sound and looking at it. If you think it is o.k. then at what speed would you think t...

This sounds more like the drive / motor which is speeding up/slowing down... this could be because: a) the drive is not setup properly eg, the gain is too loose, or current settings too high/low b) the DC spindle motor brushes or commutator could be worn out / dirty c) the DC spindle motor TACHO br...

The spindle speed will fluctuate at low rpm. Try running it above 500 rmp and see what happens. The belt is allways narrower than the pulleys on the encoder for some reason. It may be worth spraying it with a belt lubericant. Or you should be able to take it to a bearing suppliers & pick up a repla...

Operating and safety manual for Burnerd lathe chuck.

I hope this is of help.

This came with the mill or lathe so might be for the motor of one of them.

I hope it is of help.

I have made a pdf file for anyone who might be using this software.

I'd put cable questions under machines. I really think a forum restructure is in order so that old software, new software, electrical/electronics, mechanical are more seperated. It's always difficult though because you always get something inbetween like say, RS232 cable testing software - would th...

Not sure why the downloads have been done like that. Yes you do not require the INCIM directory. & you need to add the Drivers2 to the disc. Then edit or create the OPT & GO files to match as above. Thanks Martin. I will try this and post here as to how I get on with it. P.S. where on the forum sho...
