Re: Fixing banding (z-wobble) with fine threaded z-rod
I read dozens of topics about our biggest nemesis, the backlash, but I still miss some pictures of the puzzle
I'd really like to change my stock threaded rod, some of you went with the M3 rod, which is the most flexible, but what about the risk of bending it?
Others with the M5 rod as they felt it was a bit stronger, still almost twice the revolutions per mm compared to the stock 5/16" rod.
Also what about couplings for the threaded rod and stepper shaft?
A Chinese aluminum standard coupling would be enough? Any European source for them?
Is aluminum durable or will it fail?
Here I see Jenninaj went with helical beam coupling, but seems very expensive. Does it worth the expense?
