I've found an issue with my Z axis. (After fifteen years!)
It appears we don't have all the 450mm of Z-Axis travel. I noticed the limit switch cam plate looked different than the others, and in fact someone has made a slightly longer version to stop the Z-axis using the last 79mm of travel.
When I remove it, the error message 'Code 14' appears, indicating a problem with the LS904 scale.
Since this area of travel is very rarely used on the machine, it has therefor never been noticed. But, I now have a job where I need all of the 450mm.
I have had the scale professionally examined, and other than a weak reading from the scale 'head' there are no serious issues revealing themselves. I have been informed that the issue he found with the 'head' would if anything stop the scale working completely, but not in the specific area we have the issue.
I can have the scale head refurbished, but this still may not cure the 'black spot' area.
Any ideas?
