So, an update. The machine has been off for 2 or so days. Today I boot it up and it won't "reset." The opening screen says everything is okay, no warning about the battery, but it won't "reset" and I...

So this morning it was fine, booted and reset immediately as it should. I contacted the head maintenance guy at the company who built/maintained this machine, and he said the battery is NOT...

Does that mean that the battery is rechargeable? In the 20-some years I've had the mill, it has sat completely off for 2-3 weeks at times, but never had a problem with the battery.

So I booted it...

I used the RS232 the whole 20+ years I had it, it was connected to my desktop, from which I loaded programs from GibbsCAM. But that PC is gone, as I noted.

Why do I need to load anything into it...

I got it running, although the first-second time was like before: Couldn't move off the first screen, reset button wouldn't work. So I let it run for an hour or two, rebooted, and everything seems...

Thanks for the offer, DJ.

So I looked up an old buddy of mine that I lost touch with the past couple of years -- this guy cut his teeth on '70s - '80s electronics. He knows electronics, electrics,...

Battery is coming this afternoon via UPS.

I've got the board out and here are pix of the battery and the backside. I see a + on the face of the battery but that's all. I've got to find a TV guy or...

You mean leave the control on now? Or after I change the battery?

That link said the battery is not rechargeable, I thought they were. Oh well, I am going to order it tonight.

EDIT: Battery...

I got all those leads off, and pushed them on and off several times. At first boot it doesn't do anything other than tell me I need a new battery.

After running a while, I can get the e-stop and...

The battery from your link looks the same as I have. My machine manual says it's 3 v, that link says 3.6 v. Does it matter? Is it soldered in?

EDIT:
I just looked up "axial leads," and see that...

Yep, that's how it used to work.

On boot up:

Got the rear cable off, can't access bottom screw on front connection, can't even see it. I did loosen the top screw and wiggled the connection some.

This is...

Somewhere here? :(

Thanks for the tip, I will try it Monday. Do you mean just the boards in the controller?

Here's where I am so far. I let it run for a while and I can finally get the "Reset" to work and the loud relay snaps as it should. I could not do this previously.

But no matter what I do, I...

Got it, thanks! I have the flat one as in pik #1. It appears to be soldered in. I will contact the people who built the machine and will update this post if anyone is interested in these antiques.

Thanks for the reply, but I have no idea what I'm looking at. Which is the battery?

Where is the best place to buy one?

Hi all. I had to retire for medical reasons two years ago, and have been trying to sell my machines and tools since then. I have a CompuMill 2500 with a DynaPath 20 controller.

I have a guy...

Nah, it's still dead in the water. Anybody here interested in it, plus a WORKING Hansvedt Bench SMB150 EDM? Will let them go very cheap.

This website is a bit confusing.

Can I post all of my machines for sale in one place? Is there a cost?

TIA.

Anything here? Do I have a pile of scrap?

I can't believe I'm back here after 14 years.

I recently retired and am selling everything, but my Eltee quit working a while back. I would imagine that right now it is only worth scrap. My buddy...

The edited big file worked fine! :D

Ha, well you hit it! The red setting above.

When I first started this process a few weeks ago, I copied all the DNC settings exactly from my old computer -- this setting was shut off so that's how...

So, here's what happened when trying to send just now:

Controller shows: "Buffer in: load error." (same error as in my first post)

One of the lights stayed red, it was the "DTR", all others...

Heh, okay, I've never had a problem so I've never even paid any attention to those lights. :( Here they are:

What does the blinking light mean?

I did go into Device Manager and...

What lights? But yes, DNC4U is great, and at this point I don't think it is the problem. I did look through the help file some, but it was giving me a headache so I quit.

Good idea, to check the...

Hi! I can't believe I signed up here in 2007. I hope I'm at the right place for my questions. I had a good buddy who used to help me with this stuff but he died a few years ago.

My problem: My CNC...

What do you need to know?

I had this happen on my positron3a with the Z axis.
Cleaning the z axis reset button solved the problem.
I would open it up and work some WD40 into the switches
paying particular attention to the...
