Another "what do I need" thread. Vmc retrofit

Sorry for the last replies had to write them on my phone..

Yes the EXE units is an alternative but they seem to be at least as expensive as swapping them for new encoders. I really hate the new(ish) "Customs services" for items in USA. Customs here don´t give a s*it so I have to pay the same fee twice.
I don´t know how much I can expect to get for my tnc150? It might be worth investigating the "sine to square" card in the controller.
Encoders seem to be close to 100€/pcs if the AMT ones don´t work good enough.

So I guess my options are:

1. Replace the sine encoders with TTL encoders
+ Availability
++ More people has done it = more info
- Machining needed to fit them
- New wiring needed

2. Buy 4 EXE converters
+ Ability to use old encoders and cables
- Might be tricky to find 4 identical units with good price
- More used old electronics

3. Rip the converter from the TNC controller
+ Ability to use old encoders and cables
+ Cheap*
- I cant sell the old system as a working unit

Thoughts?

That does not sound like an option for me. Preferably I´d buy a controller with all this built in and I only had to connect the cables

But besides that. Is it the 5i25 + 7i77 kit I´ll need now when it turned out resolvers is out of the question?

I would go for (5i25 or 6i25)+7i77. This is more common now (the hardware is also newer) and it is less expensive.
I have both systems working at machines with me, and the (5i25 or 6i25)+7i77 is more simple to integrate on your machine.

If you need to add a full panel, a 7i84 is a good choice to the 5i25 or 6i25.

At resume a full size machine with a panel requires only 5i25+7i77+7i84, that makes a solid package with a good price.

The big downside of the 7i73 is that is 3-5V and you need to use flat cables.
The 7i84 is much faster the integration and you can use 24V, that normally you will have on your setup readily available.

I have both running in my shop and the time that was spent on connecting the 7i73 is quite large. If you need the keyboard or the lcd, then go to the 7i73.
