Ive finally figured out how to Input something like this to my controller board.

Are you still making them?

Also are they a mechanical switch rather than a grounding connection? , im sure i should be able to work that out from the digram but hey.

i wanted to say i figured this out. its very basic conversion and whoever did it used a 5v out off the denstep board to power the spindle v5 board. The denstep manual says don't power anything like this off the board. so a cheap dc psu later and all is well.

Soon i'll get round to more advanced ...

Second question then, as I said power supplies, i'm trying to understand what these supplies are.

or rather what it is they drive.

i got some way with it. the 110v seems to power another 24v transformer.
28 volts to the smart step
240v to ?? some of the replays so far.

if I touch one side of ...

Thanks Martin, that ia interesting then. Looks like I'm all wired up for Atc!

Hi all, can someone help me identify the relays I have in my control cabinet

All I can figure out is SGR for the spindle, but i have half a dozen 3 letter labeled relays for what i dont know!

VOR CIR DBR CPR and SGR

Hi mate, the belt for the y axis is a timing belt type t5, available at most part shops. measure the length of it. at a guess it will be 200mm . so T5 -200.

You wont buy the Gib strip off the shelf unless you are lucky, have one made though. i dont know the dimensions though sorry.

Ive only just become aware of this machine.
So if anyone has one they'd like to sell i'm interested at the right price.
Either the 1300 or 1300 pro, id be happy with either.

cheers

We have some stock of Balluff proximity switches BI00401A
I believe they have been used for home detectors on older Denford machines (Triacs, Easimills, Easiturns, NovaMills and possibly Orac)
They are brand new, but UNTESTED (so, no complaints if they don't work, although there's no reason why ...

Hi FGC, only just seen this sorry, i'm hoping you figured it out.
I disconnected the wires to all the steppers etc from the main plug to allow me the slack i needed for lifting the column.
shims I used were brass shim of varied thickness. a piece of ground glass and a dti to check in every ...

Thanks ive seen them there and bought one, was hoping for some used ones that might be half the price

Thanks Rob, only just seen this, sorry

Thanks i'll take alook

My Mistake, its not connected to estop, after a double check I had my wires crossed it isnt connected to anything as it stands at the moment.

On reflection today I believe it should be connected to to oiler system which would make sense.

I need another for the x axis, well i dont need one but id ...

I hoped it was an rpm sensor :)

Its in the head block itself next to and pointed at the spindle just below the belt wheel. Ive traced the wiring and it does seem to be wired to the estop which is odd or maybe a mistake.
This machine has seen some rewiring and had servos fitted in its long life. I ...

Thanks, I assume the sensor in the head by the spindle is for something else then?

I have a here an Old Triac, that i'm gradually putting back together.

It seems to be missing its X axis bracket which holds the limit, home and Balluff sensor

I have the illustration for it.
Just spent and hour looking at how it is wired it seems to be Home one end and limit the other, but all ...

Looking for one of these or even just the dimensions for one, very early Triac console version

hope someone can help

cheers

Digging up an old thread!

I have a novamill converted a while back. I dont have any of the grounds connected as Rotary E states above.

I do however have some noise issues on the steppers and i'm wondering if this may be the cause.

Steve wrote:No turning it down is better. if the motor over speeds it sparks creating noise.

If max RPM is not too much of an issue you may be better setting it at 2800RPM

Will do thanks for the help Steve

Hi If the spindle is running over speed by too much turning down the pot will will correct the RPM but as a lower voltage is creating the same top speed the current into the motor will increase.

Various things can cause demagnetization. Over current, repeated stalling, over voltage and running ...
