Hurco BMC 30 AP

Hi there,

the XYZ axis can now be controlled via Linux CNC and also move.
However, we have not yet made any further settings.
We wanted to put the spindle motor into operation, but unfortunately we didn't succeed.
There are no signals from the encoder to the Mesa card.
The encoder receives 5V (are available), the signal goes to the Yasakawa driver and is processed further. Then the signal comes out of the driver and goes to the Mesa card.
I hope the encoder is not broken.
Turn the spindle by hand, a signal arrives at the Yasakawa driver because several LEDs light up again and again.

I think I have a problem with the encoder.
It looks like oil spilled in there.
Has anyone ever disassembled such an encoder, possibly non-destructive?

 

Nope.
But as a general rule, they are very sensitive devices and great care must be taken when working with them.
If there is no rust on the disc, a good cleaning should work, use a very soft brush, hot water or rubbing alcohol, pressurized air but at low pressure.
If there is rust, do not bother with it.

Before I dismantle any more, I'll put the 5V directly on the encoder on Thursday and then I will see if i can measure any signals on the connector.
If it doesn't, there is a problem here.

If you take a closer look, it looks like there is oil on the board.

I can‘t see any rust.

I found some information about the encoder.

 

Hi,
here is a little test video.
Unfortunately there are still problems with the spindle.
We just can't get it to work.
