Hi,
I don't know if there are still any knowledgeable users of this machine out there, but I hope so!

I bought a Bridgeport series 1 interact with TNC 145 from a technical school, so in pretty good shape. I stored it in a barn for a year and moved it last month in order to get it running. While moving it to its final destination, the chain holding it broke, and it felt down 1 or 2 cm. Apparently no damage...

The battery was out so I had to enter the parameters from a compilation of MP lists I have found on the forum.

I managed to home the Z, but once I home the Y or the X it starts a rapid move and the machine stops with a "gross positioning error B" message.

I found from the Heidenhain website some infos about the possible causes when this occurs on the TNC 155, wrong parameters are one of them. Since the machine was tested working before I bought it, I imagine that the parameters are in cause.

Anyone out there would know how to fix this ?
