Gildemeister NEF 480 Retrofit

So did more cleaning before Monday hopefully the last parts for the cabinet will arrive.
The cabinet is free of dust and chips now:



also the console is cleaned out

Then the were the cable guides still uncleaned while removing most of the old cables I also cleaned them an d the rest of the machine:






​

the hardest part was the coolant tank:



after some trouble with my 7i97 (was not voltage to properly start it up) I got it running:


​
so next is writing the ini and Hal files and of course rewiring this junk of metal

This week some more parts arrived:



So now just a few parts are missing.

I opens the spindle to check is everything is OK there:



It looks good, but there was a surprise the electric clutch turned out to by hydraulic and drives by the oil pump driven my the main shaft. This can turn in to a problem when using the vfd. But this is something to take care of when it causes troubles.

After this I removed more unused cables. now it's quite empty there:



Just the spindle clamp, coolant and the additional spindle index.

Also removed the unused connectors from the back:



quite a pile of old cables it habs become



Then I salvaged and cleaned the connectors and also cleaned the spindle encoder hoping to get a clue how many increments if has and if it has an index signal. The additional one gives to signal per turn. I think Linuxcnc likes on per rev.



so reassembly comes in sight and less excuses to postpone it again are there

So did the first board test yesterday:

[/url]

Ok the first after playing pin pong. Let’s call it first contact from LinuxCNC to the mesa card.
And tested my hand wheels. And it works... Next step is to see if I get the spindle encoder running but I have no Pinout is there a kind of standard with color coding in the cable or the plugs? Otherwise I screwed and need to find a new encoder that fits.

Even with no information on an encoder, you can possibly
determine the power supply connections by continuity
testing from known IC ground and power pins to cable
connections. Once you have figured out the power
connections, you can power the encoder and then
determine the other signals with a voltmeter

this is more ore less the way I want to try it


Type TSI508 then its not readable.
Power supply 5v cd number of increments is all not readable, but easy for figure out
A86L-0024-0001
There is also an engraving C4063 but I think this is for the interface

maybe the color code for my Siemens encoders will work.. otherwise it a session with the multimeter.

I figured out the outputs. But it looks like it has some problem.



I opend it and found some of the degreaser in it not much but maybe it did some harm. I wonder if I can do something.

It could be also have issues before. I don’t know

Why do you think it has issues? The watch screen in Halshow is not a reliable way to watch for quadrature error. The update frequency is much much too slow and in user-space. Infact watching the A and B signal pins in Halscope probably isn't even good enough since that is only sampled in the servo thread. I'd say as long as the count seems reasonable and it isn't setting quadrature error alarms, it's probably ok.
