RE: [CAD_CAM_EDM_DRO] Noise Problem

Did you check the motherboard. I still think that is where your fault is,
you have swapped everything else around, the motherboard is the only common
component to keep the fault occurring from the same place. As I said the
encoder output signal from the card seem to love to pick up noise from the
SPI interface, they are not buffered so that noise goes straight back into
the card.



My Rutex R2020 drives are now running like a dream, even after I blew one up
with my owne mistake and repaired it. Got some issue with the G100 and Mach3
we are trying to sort, but the servo's are looking good.

Subject: [CAD_CAM_EDM_DRO] Noise Problem



Hi all
I'am tunning a Rutex R2020 I've just recieved , I placed it on the
first slot on the motherboard (for x axis) the other two slots have
the two R2020 for y and z axis . The y and z axis were working
perfectly during the past month of testing .

The problem is that once I plug the encoder to the x axis drive the
three axis stops moving and if move they move with a very big error
(non stable ), if I un-plug the x axis encoder the two other axis ( y
& z) restarts moving perfectly.

I'am using quality type shielded encoder cables
I replaced the encoder and the encoder cable with the ones on the y
drive but the same problem.

I think there is a very big noise problem since it affects the y and z
axis .

Any help, Ideas ?
