RE: [CAD_CAM_EDM_DRO] ringing sound

Sounds like your cable is not properly wired even though you have
continuity on each wire it would seem like the phases aren't correct.
Look at your good cable and then make sure the bad cable is wired
exactly the same as the good cable.

Hi,

Having a bit of problem with the G201 driver again. I think it is the
cable.

The y-axis works fine, but the x-axis either doesn't respond or gave
very faint sound but does't move.

Tried switching axis. This time the x-axis is OK but the y-axis is
not responding. Can't remember what I did next, I think I switch
cable or something. If memory not failing, I think the problem
follows the cable. Checked the cable with meter - seem OK.

Reconnecting, this time the fauty axis gave a ringing sound, but no
movement. Tried to search the archives for "ringing" only found the
above.

Ringing sound plus no movement is a symtom of what problem?

Thanks
