1982 Matsuura MC-500v Retrofit

Hello again chopper, I've been reading your whole thread because I'm probably going to retrofit a MC 500V, many thanks for all your effort on this, it is very useful and valuable for me.
now,
I'm want to ask you specifically how did you apply voltage to the analog line?
I'm guessing you connected an external variable power supply (+/- 10V) ? or did you use a potentiometer?
IF you used a power supply did you connect the ( - power supply signal ) to the (- common servodrive)? how did you connect it?.

many thanks for your repply

Might be too late, but I have a the sister to your machine more or less. If you have any of the old parts let me know. I have a problem with one of the servo packs and CPU board. I would love to find out what all you had to go through to retrofit the machine.

Ok, I think the "next couple days" is a loose term i guess..... Any update on posting the config files?

I think I will start a "post the config files you promised" task force here. It’s clearly needed as you are absolutely not the only one who complete their machines and promise to share their config, but don't follow through. I know it's easy to move on and continue the journey. But it's a loss to the community when examples like this isn't posted for all to see and learn from.

And.... in many cases, like this with CL and other complications, the whole config dir is needed. It's important to have all the relevant files to get the whole picture and understand it. And I guess that is the point here, to look at working configs to learn how to cook up your own?
Complete configs of machines with working ATC's are not common around here. I still haven't found a single one with CL. And I have been looking long and hard.

Yeah... got busy making parts, money, and taking care of family. I am sure you understand unless you are one of those super rare people who never forget anything

I am happy to post them though so they are available and also thanks for the reminder.

Just like everybody yes.... Of course I understand, and I can say I'm guilty of doing exactly the same thing myself :laugh: :laugh: :laugh:

But I know most people will respond well to a friendly reminder like this, and then we all get to see another working config that we can use to compare to our own configs. And maybe then also get exactly that minor thing we were struggling with nailed by having a verified and working example.

I hope to get around to make a list with links to the different working configs lying around this forum. I know I wouldn't be able to get the full grasp of this without these examples. For me the (overly!) simplified examples in the documentation isn't enough. As a start yes, but when you start trying to piece it all together it's so much more helpful to have complete setups to study and learn from. In particular ones like yours which are complete and tested on real life machines, not only a minimal (theoretical and very trivial) example where all other parts aren't shown.

So thanks for sharing!
