Fagor Innova Dro Failures and Errors Needs TLC?

I have the pleasure of giving TLC to a Bridgeport that has been rode hard and put up wet.

Hygiene and love have not been a priority. When trying to use the Dro the Y axis is OK but the X either will not respond or if it does as soon as you move the table it errors.

Can I get some tips on what to do troubleshooting wise?

Thanks

Do they give false readings or does the display actually display an error message? If they are glass scales which I assume your Fagor has this is a common problem. Although it doesn't happen very often as in periodically many people do run into this. Most of the time it's cause by dirty scales.

You use a cotton swap & denatured alcohol (isopropyl will work too, higher the % the better) to swap the glass scales clean bh reaching through the seals. Try not to blow air as it may damage the read head if there's a lot of chips inside & will only blow oils/coolant around. Some scales can be disassembled if they are real dirty & you need to clean the read head too.
 
Thanks,

I have never removed a scale so I'll be in uncharted territory and am glad I asked before guessing. I may have just used an air hose. I hope it just needs cleaning.
 
Sorry, I didn't answer your question.

Reset it to zero and as soon as you move it either freezes or blinks.

I looked for Google videos of servicing scales. I wonder what Fagor or a Fagor service center would charger to do the service? Any recommendations? We are not the original purchaser.
 
Normally you don't need to remove the scale. Just pull the cover off and you should be able to access the glass.
 
Thanks, I work evenings and I'll try and give it a look tonight.
 
OK,

I have to apologize because I got my scale issues mixed up. The one I said was not responding or error alarming was for the one on the Victor 1640 I am also trying to revive.

So lets begin again.......... This one just did not respond.

I pulled the scale off the Bridgeport X axis and as soon as I began to do so I knew it was going to be bad. Some one has let the table over travel and smashed her up.
The scale is at least 36-inched long. I sat the thing centered on top of the table and could tell they failed to set the auto and hard travel stops so the scale would survive.

As soon as I tried to back out the mounting screw and seen it was elliptical in behavior I lost my hopes of this just being a cleanup.
It pulled the wireds out of the sensor!

Here is the pic. The screws on both ends looked the same. I didn't get the other one in the pic.

What can I pick up a scale for. Are there refurbs? Thanks

Holy crap! Never heard of refurbished scales & it may not be worth sending to Fagor for repair if they did offer the service. Where the wires got ripped off, is it covered with epoxy? Any possibility in soldering the wires back?

If not, what kind of connector does your scale have? The most common is the D-Sub 9 (looks like a VGA connector). You could buy a replacement, doesn't have to be Fagor as I'm assuming a Fagor scale is pretty expensive.

Best bet is to contact DROPros to get a replacement scale. They sell Fagors so they should know exactly what will work for a replacement. An Easson scale scale should work. To prevent future crashes, your scales should be an inch or 2 (travel not OAL) longer then the max travel of your axis. It would be best to get the correct size scale now that you have to get a replacement. Ask them about this & they should be able to take care of you. They are located in the US & their customer service is excellent.

If you're on a budget, you can order a replacement scale cheaper from China but you will pretty much have to do all the research yourself in what scale & size to get that is compatible.
 
Thanks,

I was just wondering about refurbs. You never know eh?

I have visited DroPros. Looks like a good vendor.
On the other end of the spectrum I stumbled into CDCO Machinery Corp. Everything there is frighteningly cheap.

We will have to see how enthused I can get the boss.
They kind of let the shop go to waste (former CEO slaughtered the place) and I have already demonstrated the value added by making repairs fopr them using the shop as is.

It looks like to get a longer scale I'll have to drill and tap holes in the table. How hard is the metal?

Meanwhile for all my DRO "must have" needs, I use the below SuperMax that has a working DRO but no auto x axis.
The DRO is an OLD Futuba and the readout is dim but it works. I see there is a Ground terminal at the rear unused. Do you think this may be why the display is so dim?

Good luck with that Frank dude at CDCO, I will never purchase something from him again. Many have good experiences but many others have not also, do a search on the net or even just here.

Yup that scale looks way too short. Wonder if that's the same Futaba that manufactuers RC controllers? I doubt the ground screw on the display is the cause for a dim display. I would think that given the age that it would still use LED displays but if it is really old it could be vacuum flourescent display, those get dim as they age. Not sure if they were used in DRO displays back then though.
