Evenin folks,
You might have spotted a thread I had about a DIY CMM a while back. Someone suggested I get an old one and screw with that.
Ended up being exactly what I did. I have a J403 in my basement. Heavy bugger; weighs 1800# all together. I finally got around to taking it apart today, and I think I understand it a bit better. We’ll see how many photos I can cram on here:
Apparently the Z-axis is manual, while the x and y axes are semi-auto or something. There’s a lock and fine adjustment, but no screw.
Nothing too complicated here; couple of switches, servo and screw. The weird thing is, the wheels are on a linkage that seems to engage by air. I’m not sure I understand why. I guess this system is supposed to be convertible from DCC to manual? Not sure why you’d want to, but OK.
This is where the encoder signals end up apparently.
I think, I don’t know, that this might be the box for the probe signal to go through. Maybe? I guess? Not really sure what it is. Company went out of business apparently.
Again, no clue what this is. It takes the same plug as the control box, which makes me think it’s the servo drivers. I’ll have to take it apart tomorrow and see.
It’s an exciting project. Even if I can simply get the encoders to send a signal, I could retrofit the thing with new screws and servos. It came with a copy of Virtual DMIS, which is kinda cool. It’s not exactly my top priority, but it’d be cool to hear what you guys know about the stuff I don’t. More to come.
