Re: Yep, another machine can't connect

If you have a PC that is running XP you can run a windows DOS window within that or possibly DOSBox on win7. Did the machine come with a 'tutor' keyboard'? DOS systems use them. there is some info here http://www.denfordata.com/pdfs/mirac_pc_600dpi_hq.pdf on running DOS. I think you need to try the ...

Re: Yep, another machine can't connect

Just a thought and Martin might be able to confirm this as a means of proof. Have you tried dloading and running the DOS control software, http://website.denford.ltd.uk/dos-vintage-machine-information/ You will need to set up the FANUCSLD.GO file (example below but would need to be what is needed fo...

Re: Yep, another machine can't connect

The eproms are erased by UV light when the window is exposed to it. So keep it covered, the stickers we used were a metal foil to prevent the UV penetrating. It has probably been fine as the machine will have kept it in the dark. In the 80's / 90's I used to have access to erasers, readers/writers s...

Re: New guy, old lathe, advice please!

Hi, Ive had 'the guy' on ebay do a nut for my Boxford TUD. I sent him my old unit and the screw as he said he would try and make it fit as best as possible. It is evident that my screw is worn as the new nut shows less back lash at the section not used much. Worth doing to get it to a more usable st...

Re: Denford Novaturn Desktop Tutor

Hi yes, given the age on the plate and the fact you still have the desktop tutor keyboard it looks like it will be a DOS based control rather than the VR Turning windows based software. A lot of machines had the control boards updated to run on VR Turning so getting a look inside the box would prove...

Re: Denford Novaturn Desktop Tutor

I have seen them sell from between £200 and £1500 depending on what the control is. If you post up a pic of the insides of the back box and the the label on it it would help. All depends who is in the market and where you are.

Re: Spindle speed incorrect.

Hi Max, I have seen various posts over time on spindle speed issues (not sure which machines though). The problems have been from various issues, faulty encoders, VFD issues and spindle motors demagnetising. Have you downloaded the wiring diagrams? I know the speed controller on the micromill, micro...

Re: CNC electronics textbooks/reading material

Where abouts are you? I am about to start upgrading a Starturn 5 to Novaturn specs. If you are looking to replace the control on that rather than pulling it to bits we could maybe work something out.

Let me know

Ohh I had hoped you had it sorted. No I was trying to say I hadn't felt put down and just wanted to show I wasn't trying to teach you to suck eggs. For VR2 I think there is a patch so you don't need a dongle but you do need a licence file though. When I was researching my Starurn 5 (not common) I fo...

Re: MIRAC. ERROR 128.

It's always difficult to judge peoples experience with systems and hard not to discuss the best way to suck eggs :) having said that that other point of view can often bring a moment of realisation.

Martin is great with digging out amazing bits of history. let us know how it goes!

Re: Denford Micromill software help

Im a bit puzzled why there is no RS232 plugged into the top board running to the outer case. It doesn't look like it has just become loose, fallen out and is hanging about either.

Re: MIRAC. ERROR 128.

the only thing I can think of then is that as you said you dloaded the software from Denford recently could it be just a case of the GO file is calling the wrong port, with 3 being on board, my GO files calls $2F8 3, The one in the thread calls $3F8 4 and yours calls $3E8 4, so that shows little con...

I currently run my starturn lathe on Win xp through a 'windows' DOS window so you don't need to go back to 98, just remember to disable screen saver and power saving as XP doesn't realise you are working with the PC in DOS. Does your machine have the 'tutor keyboard'? if so then Im pretty sure that ...

Hi, I've only dealt with Denford UK as this is where I am. I'm not familiar with the Mirac but a machine on the 2000 year I'm not sure if that would be a DOS machine or a Windows/VR machine. IF it is a DOS machine you can get the software free, if a VR machine it would need to be purchased. Have a l...

Re: Response time

No that's all they should need, the only thing is the 32pin eprom (chip) with the little glass window should have a sticker on it saying the software version. without that it is hard to be sure if it has ever had an update. The sticker is also meant to be there to stop UV getting to the internals of...
