Howdy- I've replaced the spindles on a few of our Roland 52Ds so far, following the instructions to the letter. Including this bit:
I've gone back behind the service panel to clean and regrease the linear ways, and I'm seeing that the conductive plates on one or two of the spindle units appear to have wandered, and are contacting the spindle, instead of floating close to but not contacting the spindle. One of them is actually bent back a bit, because the plate has been pushed down past just contacting the spindle body- it's springy steel so just springs back, but it's still pressed against the spindle fairly hard. The adjustment and set-screws seem tight, so I'm not really sure what's going on there. The spindle body can't move, given how it's mounted, so the contact plate assembly *must* be moving, I'm just not sure how.
More to the point, what is the contact plate for, anyhow? Is it a grounding/static dissipation/ionizing thing? What's the consequence of it touching the spindle improperly during operation?
