Hurco BMC 30 AP

Hello,

I'm from Germany and last year I bought a Hurco BMC 30 AP CNC milling machine with a4th axis that I want to convert to Linux CNC. In the past I have already converted 2 older CNC machines to Mach3, but I was never satisfied with Mach3.
Now I would like to try Linux CNC, but it will be a longer project because I currently have no experience with Linux (CNC).

The machine has an Ultimax 3 control.
The servo motors and drivers are from Yaskawa and I would like to continue using them, so I bought a Mesa 7i97.
In the future I will still install glass scales.

Here are a few pictures, does anyone have a circuit diagram of this machine?

greetings

Stefan

It looks like a nice machine.

If no-one finds a circuit diagram, then you can probably find all that you need to know from the Yaskawa manuals.

Does the machine run at the moment?

The machine is currently not working.
I cleaned them up and some parts got a new colour.

I have already downloaded and looked at the Yaskawa manuals.
The exact process of the tool change would be interesting, in another thread I read that the circuit board for the tool changer should be retained, a circuit diagram would be interesting for this, because I want use them.

We are currently removing the old electronics, then I install the Mesa card and then we will rewire everything

Hi,
I retrofitted a BMC20 about 6-7 yrs ago
Mine had FANUC motors and drives. You should not have much trouble with yours since a Hurco is PC based from factory.
Good looking machine you have there!

I did a retrofit of a BMC20 a while back, the log is on this forum.
Had to change the drives as they failed one by one, but they are very easy to tune with LinuxCNC, took about 5 minutes.
Then the spindle drive failed .... made it work again but every once in a while it would fail to start.
Yaskawa drives all of them.
The tool changer stuff is quite simple, just do not remove anything but the control.

Hi there,Unfortunately, I didn't have much time.I am currently working on the Hurco again and soting some cables.Unfortunately, to this day I don't have a reasonable circuit diagram, that makes the retrofit a bit more difficult, but not unsolvable.There are still a few questions, especially the emergency stop is another topic, since the converter documentation does not contain one-sided information either.The tool changer board flies out, I only use the Brake Pack and the controll will do the Siemens S7.
I install a 100l air pressure tank at the side of the machine.
