Another thought came to mind on the y-axis. Does it move smoothly without the y-axis engaged? The acme screw being out of place can cause friction if the mount for the split nut is rubbing against it. I'm just tossing out obscure ideas at this point. :-).
What's the link to the split nut upgrade? I think what you are seeing was the updated carriage installation instruction for the z-axis, not an actual split nut upgrade. No benefit, simple a different location for using the new style carriage on the old machines. If I understand you, the acme screw is rubbing against the mount for the split nut. You can find all the adjustment room you need in the brackets that hold the acme screw. Adjust the screw with the carriage at both extremes (left and right). If that does not work, you might need to look at the location of the mount for the split nut. It might need to be shimmed or lowered. The screw should be in the center of the mount. I'm assuming your screw is not bent. I have worked on several of Legacy's machines where they did not work out of the box due to wrong parts included, or things where not machined right or the machines where not built right by the owner. Sometimes you need to look at the whole picture using your head to really figure out what the problem is. I've also known several members to live with problems they never new where a problem. That's where talking with others really helps. I hope this helps some? -Tim ----- Original Message ----- From: Brandon Khoury To: legacy-ornamental-mills@googlegroups.com Sent: Thursday, November 15, 2012 11:32 AM Subject: Re: Legacy 1000ex setup questions. I have already taken the sled apart and reassembled it, ensuring that everything was square. I have not checked the long side rails, but they wouldn't impact the friction in the Y axis. I'm pretty sure that my effort to minimize movement of the router plate has resulted in the increase in friction, not that the rails are out of square. I have a couple ideas to help reduce the friction. I'll finally have a chance to play with a bit tonight. I'll let you all know how it turns out. Also, I downloaded a pdf from Legacy regarding a split nut up grade for the 1000ex long drive screw. It looks like the plate lowers the split nut slightly. What is the benefit here? I noticed that sliding the carriage down the rail, without the split nut engaged, makes a lot of noise because the two are in contact. Kinda like running your finger across the face of a wire framed fan as a kid. My assumption is that the upgrade will lower the split nut slightly to reduce any unnecessary contact. Talk to you all later. Brandon -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
