Rebuilding a Bridgeport mill

It looks like the Internet’s resident steampunker is moving up a century or two. [Jake Von Slatt] rebuilt the CNC portion of a Bridgeport Series II mill so it can interface with a computer. It’s a feat even more impressive than moving the mill into [Jake]‘s garage.

The first step of the build was tearing out the BOSS 5 industrial microcomputer and replacing it with a Win XP laptop running ArtSoft’s Mach 3. This allows G-code to be displayed directly on the screen. The old power supply for the mill did give [Jake] a few problems. The Gecko stepper drivers that replace the old electronics couldn’t handle the voltage of the old power supply. That can be dealt with by opening the transformer and removing a few turns of wire.

[Jake] has been sending in a few of his hacks as of late, so it’s good to see Hack a Day has another fan, especially one of [Mr. Von Slatt]‘s caliber. There is a problem with the mill modifications though – [Jake] hasn’t figured out how to program it. If any HaD readers would like to chime in on the best way to program G-code for the mill, feel free to leave a message in the comments.
