Martin thank you for your reply. After moving the carriage assemble back and forth 2 thousand times, I finally had noticed that the cables seem to be contributing (variably) to the resistance near the end of the movement. I had done exactly what you suggested and further noticed that the clamp would not keep the cables from walking back the other way, so I pulled them out and applied a little adhesive to keep them from moving. Additionally, the larger cable hold-down “guide” seemed to be installed upside down when compared to a couple other pictures I found on the Internet. Flipping it seemed to give the cables a little more breathing room. I also found I could lessen the carriage movement force by adjusting the free-length of each cable (before applying the adhesive) so that they remained separated throughout their travel and not bind up against each other. I appreciate the message that confirms this delicate movement is very finely designed. Perhaps there is a less-stiff material that could be applied instead of the current sleave? Anyhow it seems to be much improved. I sure focused on the wrong things for a while. Fun to learn – I do like the table. I’ve got a 4002 and 4004 that I like better, but this one will be a great starter table for a friend of mine.
