cool, glad you found a work around

Pete

you should be able to find the drawings on the forum http://www.denfordata.com/bb/viewforum.php?f=37 you will need to do a bit of checking as to which is which, machines got upgraded over time and this wasn't always recorded on the plate. Yours is visually older in that the electronics are in the se...

Just an addition, you need to work out what has failed, I know the control boards are prohibitively expensive new, so second hand would be your only option if so, unless you could go down to component replacement. No idea what the cost of the speed controllers are. If it is main boards, it may be a ...

I would be looking at all the components for evidence of the pop. Hopefully Steve or Martin will be able to say where to look in more detail. It could be on the speed controller rather than the upper board. If you are OK with a meter I would pull the plugs from the lower board and check the output f...

try running the 'easy upgrade' or 'easy update' can't remember which, it's part of the software on the CD. you should be able to get it to talk to the machine.

I have had this, i was able to solve it by a full deinstall and reinstall of VR5

Pete

the Z motor is not switching off as it is not seeing the switch state change, there is the possibility that the wire is damaged within the connectors so this could be why this is happening with new switches, also is there a possibility that the contacts on the switch are not the same so in fact it i...

good work! bit of 3d printing in it too (no surprise lol)

It would be good to know how effective you find it to be.

Pete

Hi, hope you on the better side of ill!! The cable indicated looks like the sort of thing you could try. Static caused by extraction is an issue, we have the metal cased 'henry' work shop heppa vacs on our routers in work, we have seen it arc between the lower and upper body over the runner seal whi...

Not sure if the Denford control goes at things straight at full speed. I would have thought the Sprint controller as a stand alone unit operated by a pot on the 3 wires would just have the 10v there the wiper picking up the voltage it is set to and then you enable the drive. Unless the 10v on the Sp...

As far as i know its your drawing B

Pete

I was going to say, I don't know, but did have a feeling you needed to enable the spindle some how which would normally come from the control board. My only other suggestion would be to look at those PDFs I had uploaded a while back.

Glad you got sorted.

Pete

look out for the starturn and novaturn too. Might still be some schools selling them off.

Pete

just had a look at the Starturn PC S[print controller 2.pdf,

Its the bottom 3 on the left, 10v, min, i/p
min to the low side of the pot,
10v to the high side,
I/P to the wiper

It should be the bottom row of connections, there should be a 0v, 10v and wiper or signal, something along those lines. You need the slow side of the pot to 0v, the fast to 10v, the other to the mid connection/wiper. Have a look here http://www.denfordata.com/bb/viewtopic.php?f=46&t=4778 I think one...

The school will need to have the software on the PC to control the machine, if you are talking about generating CAD files then wanting to post process them into G code then you can use the Denford software to do that but it is PC based. You can do the designs on any CAD software as long as you can e...

Hi, I just typed up a long response then realised i had put it all done in my previous posts. Denford are a company, pay em and they would sort it, but it's megga money for control boards. They do come on here and from looking at the post about this problem that was linked they have gone through all...

Martin he is using a very different vacuum bed which has lots of very small holes that are all open unlike the Trend bed with the ball valves. I think it is more designed for use on a vacuum cleaner which requires a constant airflow and will act as a form of extraction at the same time rather than a...

Picked up on this from your other post. Martin has been the guy at Denford that I have known as 'the man' for the 19/20yrs Ive been using their machines at work. Came out to fix them a couple of times back in the day. I'm not a 100% but I think the Beta eprom should run VR2 or VR5 (not sure on the V...

it just plugs in to the parallel port, it is a pass through device and has a socket on it so back in the day you could still plug your printer in. I am sure there was/is something about being able to use the VR2 software without the dongle,the later licence came on a floppy disk and it added a line ...

Yep same spec as mine, they just aren't designed for use with the type of bed you have. Did you try it with the rubber and cover all the holes? On the original Trend units the version they did for use with a vacuum cleaner had a fluted nozzle then went in to the pipe from the vac, this allowed it to...
