Ok, so I installed the new rod. Don't make the mistake I did and only get a 200mm M5 rod because it's going to be almost too short. Mine barely reaches the top of the threads. get a 250mm or 300mm and cut it if need be. It's nice because you can adjust the backlash while it's installed.

I think it's best to print in nylon, but post if you use something else.

New efficient/easy/true anti-backlash configuration.

So I found a new way to add an adjustable anti-backlash nut to my m5 rod setup. It's actually quite simple but looks very promising. I was playing around with some ideas and when the prints weren't behaving like I wanted them to I tried a few different configurations and found something that worked. I played with it for about an hour last night and could not get it to fail or even degrade the slightest!

Basically there are 2 nuts, one with a washer, and a piece of Nylon (Taulman Bridge specifically) acting as a lock washer. I attached it to my cordless drill and cycled many time with most being short bursts at different speeds seeing how it's actually going to be subject to. The nuts stay locked together at multiple tensions. If it's too loose, we're talking way too loose to be effective, the nut won't follow back up. At no time did the lower nut cause a bind because it kept tightening which would be really bad during a print.

This could be adapted to other configurations as well. The nuts I'm using have washers already attached to them which is nice. I'll post the STL files and directions once I get it finalized. The model still needs some work.
