Biesse Rover 346 Retrofit

The power supply is just a rectifier and filter cap. Dont know if this would work for field power for the 7i77. Not really regulated this power........

You can replace the existing power supply withba new one, but i would use the exisring one. Just be sure to use another power supply for the 7i77, and set the jumper to use separate Vin and field power. 7i77 has that option, but the default is set to use the same power.
there are a lot of Biese machines where i live, but no one will pay 7 to 10000 for a retrofit.
Your machine looks really nice, so it is worth the effort to retrofit, for sure.
The last one i was called to check, was in a misserable state and hardly working, it took the seller 3 hours just to make an actual cut.
Good luck with retrofiting, you will enjoy working with it once it is done.

The Rovers are good machines. We have many of the different Biesse models (including the 346) where I used to work (and still do contract work). May be able to find a schematic/manual for it, unfortunately, they are Christmas shutdown now.

That would make my day if I could find schematics......

You have 2 power inputs from what I know thats.... 5vdc in and field power in. Is there another one?

Yes there is. There are two power lines on the field power connector, there is a Vin on pin 5 and Vfield on pins 1 2 3 4. The 5V is logic power so I always use separate power for it.
PCW is welcomed to chime in about this as I got the Mesa cards 2 days ago and so far I only tested the 7i76 on the bench ( well living room table ), but from experience it should be like that.
There is the W1 jumper that has to be set to the right for use with separate power supplies on the Field power connector.
