Pete...cool to hear you got a cnc lathe. Like you, I recently upgraded my converted RF-45 to an Arrow 500......for making air rifles......lol. I would have really been shocked if you had bought a...

My friend has a Lagunmatic 320 with a Dynapath control. I have been running the machine for a year and a half with no trouble. One day, the exact same thing you described starts happening.

Long...

When I did mine, it was just a plain straight through cable. I had a hard time finding one locally, though.

Good luck.

Hi,

I have a Kuka KR150 with the PM6-600 servo driver.

I'm trying to gather enough information to decide if retrofitting a new control is feasible.

Has anyone done anything like this, yet?...

Hey Pete......your understanding of my comment was certainly not my intent.

Sorry for the miscommunication.

Hi Pete,

I haven't really followed too closely along here. I remember reading that you were deciding on whether to run analog or digital.

I looked at the Teco information before, and didn't...

My batteries were all completely dead, but my monitor worked......so I don't think that is the problem. I would replace all of the batteries anyway, though. Try this link. About 12.00 each. ...

Thanks.....I had a good time working on it this summer. I would have had a hard time getting a machine like it if I had to buy a working one outright. Buying a junker and fixing it up was the only...

I actually don't have a whole lot of experience with these things. I just got mine about 4 months ago, and have been doing nothing but repairing it.....and cleaning and painting.:D

I've waded...

It seems like a decent deal if you are confident that you can fix it yourself.

The machine scrap value is about 1000.00 to 1200.00.

It appears to have a chip conveyor, too.......although it...

Pretty sure it's a T-1.....if this is the one on Ebay.

I personally don't know what that alarm means on the T-1. I have a 86' QT20n with a T-2......and alarm 101 is a x+ soft limit alarm...

Moving the head is fine. I use "gas springs" on mine inside the column to provide counterweight force. It's hard for me to remember, but I think I used 2 100 pounders.

The quill has so much...

It's been a little while since I went through this same stuff.....so I'm slightly fuzzy on the Mach part, but I believe you are on the right track.

It depends what screen set you are using.

I...

The Teco drives can run in digital or analog configuration......making them compatible with most any control configuration.

Mike

Just a thought......If you can muster the purchase of one of the Teco drive units that you're looking at, you may just consider changing out your drive and/or motor first, before going for the whole...

I forgot to mention that there is someone who has undertaken an Arrow 500 on the Dynamotion yahoo forum.

I just remember seeing the title.....never really looked at it too much. The guy may be...

Pete.....I would give the Dynomotion stuff a serious look.

I have done a few machine retrofits with their systems, and they are very, very capable and versatile. They are not really plug and...

No....not Phillip....I'm as pale as they come.:)

I stumbled across my lathe sitting out in a field by a local airport. I eventually found the owner by another coincidence and learned he was going...

I can certainly relate to the ups and downs of your story so far. I bought a Mazak Quick Turn 20n a few months back, and it has been a slow, painstaking process to get it going again.
...

I have done a few retrofits and new machines with Dynamotion systems, and would highly recommend them. There really isn't anything you can't accomplish with it. It helps to know C programming to...

Also for the point of future searches.

1. A Mazak will not zero return if there is a NMI error.

2. The axis drives will not enable if this is the case.

3. Not all machines require the...

I would say the best advice would be to call Dynapath and order a manual.

They are nice manuals, and it will give you everything you need to know.....and you'll always have it as a reference. I...

Ok.....that opening post was from 2008. Didn't see that at first. How does this stuff turn up so long after origination?

I suppose he probably has his manuals by now. :D

I was in the exact position as you a few months back. I kinda chuckled when I saw the account app.

I told the Mazak people that I don't have a business......I'm just a guy rebuilding a lathe. I...

This may or may not help.....but on our 1840 VL lathe, I tried for a long time to get a working post for FeatureCam Turn. I followed the instructions in the Prototrak manual which said to use the...

The control has a keyswitch at the top that locks the control. Both positions of the switch read a closed contact.

I opened the switch by clipping one of the wires and I can now enter the...

The machine was said to work.....but it has been powered down for about a year.

Unfortunately zero return the machine means about as much as return home to me.

There is a NMI Emergency stop...

I picked up a 1986 Mazak Quick Turn 20n a few days ago and just managed to get power to it this evening.

Much to my surprise.....the control booted up and the hydraulic pump created a small...

FWIW......I'm going to grind a new ballscrew to replace my Y axis Roton on my ZX-45.

I work at a shop that does a lot of ballscrew and shaft grinding for the aviation industry. I am in the...

I'm using an Aloris insert cutoff tool, and it seems to like a sfm of about 275, and a feed of .005 on 4140.

275 sfm on a 1.5" diameter is around 700rpm.....you're going pretty slow if you're...
