Hi all,
As mentioned in the thread about building a DIY tiltrotator, I thought I’d start this thread to cover some of my other workshop builds, projects, and attachment builds.
To start with, I’ll go through the retrofit of a CNC Bridgeport Interact.
I paid £600 for the Bridgeport on the condition that I removed it myself from the college workshop. The machine was actually in pretty good condition, as it had been sitting there for quite a while with very little use. It had essentially been retired from use as it was considered unsafe by the college.

The machine was originally fitted with a Heidenhain TNC 151 controller. It would have been possible to drip-feed programs to the control via a laptop, but after doing some research it sounded like this could be quite unreliable with the particular control I had.
Another issue was the power supply. The machine required three-phase power, which meant I would have needed to buy a phase converter to run it. At the time I didn’t want to spend the money on a converter only to find the machine still had control issues.
Instead, I decided to go down the route of retrofitting the control system and converting the machine to run from a single-phase supply so it would be more practical for my workshop.

do it as well as you can,but learn to do it better

presumably all the stepper motors were running 240 volts anyway? :unsure:
so only main motor and suds to change motors on?

I've worked on /used a Hyundai CNC lathe.
It is 3 phase 415V, but inside the cabinet it's all 110V

Seemed a bit odd as Korea normally runs 220V 60Hz

lo-volt control is quite normal on most machines
