Retrofit on Hurco KM3P

[Dave Rothermel]

We finally got rain today. They say we will be in the middle to upper 80 this week. I can handle that. Wish we lived closer to you. Oh well. Thanks for the info. dave

What are you doing about the ACC relay?

[Jackal66]

efinkg,

Are you talking about on the B_o_B?

If so, I will probably hook up my coolant pump to it, and the smaller relay will open for an add-on later.

Dave,

It would be nice to live closer together, but I wouldn't wish this weather on anyone.

If you are asking me, the acc. turned on the servo transformer.I gutted out all of the electronics. I am using the acc. contactor to turn on the servo transformer wich powers my gecko 320x's . I also will use it to power the
PMDX 126.on 220 volts. I am powering the relay from 110 volts at the control panel. When I power the relay, the gecko drive and the bob powers up. Hope this helps you. The acc & the forward spindle relay had a 3UA Thermal delay
relay on it. I took that off to get the relays to work. Don't know what they were for. Dave

When I trip the ACC relay, my servo motors all decide to drive and ignore the limit switches. Weirdly enough, they're fine if I bypass the ACC relay entirely.

Here are some more pics from Dave.


This is where the PMDX board & Geckos will mount.


He is making all of his stuff out of wood to see if he like it first. I think the wood looks great. He is doing such a good job that he should keep the wooden cabinet for the controls.


It looks nice and whatever finish he decides will keep the oily finger prints off.

From the looks of his handiwork, he may be one of those guys that can put a laminate on it and make everyone jealous.

Looking good ,Dave.

Keep up the great work.

Jackal,

Thanks for taking the time to post the photos. This will be a big help when I decide to do my conversion. I'll be following this thread closely.


thanks

Guys,

I'm glad to help in any way. I don't have a lot of electronics knowledge, but I will take pictures & check things (readings, voltage, ohms, trace wires, etc) on my machine, if it will help someone.

I haven't checked it out yet. The X & Y use proximity limit switcher.
I am going to try to use them. Jack, I see you changed the encoders.
Is there a reason you didn't use the old ones? I really value your input.
This thread vary helpful. Dave

[Jackal66]

The reason I went with the AMT-103 encoder was becasue of Mariss at Gecko Drives.

Several times, I've read where people were having troubles and he would recommend this encoder and it solved their problems.

Digi-Key - 102-1308-ND (Manufacturer - AMT103-V KIT)

Also, it would be possible to use the old encoders, but there was no real step-by-step how-to on setting them up.

These Amt encoders are $23 each. I can afford to keep a spare or 2 around.

The factory encoders are like $375 each, and if you buy one off of e-bay it may be bad, too.

Here are new Hurco ones:



If you search you can see that Mariss highly recommends this encoder over everything else.

That was my only reasons.

Plus, I like to use parts that some else has already sorted out the problems and make it a bolt on & go.

Dave,

You were telling me about how you were mounting your Geckos.

Here is a few pics of mine:

This is the swing out door that had the low voltage power supply mounted inside.
Will get an updated pic with the Geckos mounted.

I know its a bit late now, but I prefer to remove the back mounting panel and lay it flat on the bench, especially if it is down by the floor!.
It is often a two man job to get it back in but it is way easier to lay things out and mount them.
