Today I acquired...........

Kayos · Oct 9, 2016

2 vintage flash units, Metz 184 that's missing its power supply and a Prinz Jupiter 372 complete with its lethal looking mains lead (no adapter, it plugs straight in)
Seems to be in working order too

The other day I got a bunch of scrap electrical panels from the bin at my friendly scrap yard.
Spent a couple of hours this weekend stripping them down for the useful bits:

there is a world of stuff in them isnt there.
back in feb i was at the same lark, i tripped over a electrical box at the scrappies and when i opened it up it was full of stuff similar to what you have there, £5 he charged me for it.

i didnt think too much of them din terminals until i priced them, they arent cheap if you need a lot.
on the downside i have a box of electrical 3ph units that i havnt a clue what they are for, yet anyways.

Here's the control enclosure for one of my CNC routers. I will be building another soon and it's all the little din rail bits that add up and eat into the budget.

Lol that's what put me off CNC

An IP-S, they are excellent

Using one on the Plasma I am doing and have an IP-A on the Chiron. If going AC servos on the new one then I would recommend running them analogue command and using an IP-A.

MattH · Oct 9, 2016

The current one runs AC servos with step / direction (leadshine units).

I have another set for the next build. Any reason for Analogue over digital?
Is that because of noise from the arc?

Lol. You can build a basic stepper control box for a couple of hundred easy.

Hood · Oct 9, 2016

The IP-A has the advantage of updating Machs DROs from the encoder position and thus you can whack the E-Stop and you do not have to re-home as Mach knows where the axes are. Same if you disable the servo drives you can manually move an axis and Mach knows where it is.
One thing a lot of people do not realise is every time they put Mach into Reset (assuming you have Enables to the drives from Mach) the axis position can change slightly and thus you can be out of position the next time you enable. This can be due to belt tension, or even gravity if a Z axis, acting on a disabled motor. So if your controller does not update Machs DROs you should always home when you bring Mach out of Reset.

Can the Leadshines be set for analogue command?

Ah, closing the loop.

Yes they can do analogue. The Tekcel router we use has closed loop DC analogue servos and it's something I do like.
I haven't purchased another CSMIO yet so I will look at the IP-A. Thanks for the heads up.

Hood · Oct 9, 2016

Only reason I have the IP-S is because I bought it prior to the IP-A being available. I had it on a small lathe I did for testing but now it is on the plasma build, if I had not had it sitting around I would have gone IP-A for the plasma as well.

The IP-S are still excellent controllers though

Just need a bit of practice and you'll soon be building panels...

One I made earlier :laughing:

@MattH
I see you got some decent relay bases.
I use the 20amp and 30amp relays in them, so I know they are worth a penny or 2.

A good find.

I'm pleased, paid £20 but should of been £10 (long story). Plenty there most of the time as well if i need more.

Do you fancy opening a northern office, I can do those as well

Currently building 10 (small ones) for the RAF, used in lead-lined Portacabins for x-ray work. Can't have x-rays firing about willy-nilly unless the doors are closed and all the lights working, you know

Are you using Safety PLC's?, saves having banks of safety relays (and their wiring) - example (other makes available)

Pair of spring compressors from autojumble £5.

another project although this one doesn't need much doing, it starts , runs and drives well, a couple of loose wires etc the usual landy things. very good chassis and recent new rear springs. rear cross member is solid. and it is tax exempt. needs door tops, bases are saveable, pretty straight for a 1961 motor.
