Topic: Change Z rod, and firmware

Hi guys,

A couple of months ago I've found a topic here about replacing the Z rod. Now as the parts have arrived, I can't find it. Could you please help me with instructions on how to get rid of Z wobble?

I would like to use an M3 rod with a new motor. What should I do when replacing the 5/16" rod?
Also, what settings should I change in the firmware to get the best result? I've seen some methods, telling me I should use 0.3xx mm layer height instead of 0.3 mm. What's the math behind it?

Thanks!

Silly question but why do you want to replace the motor along with the zrod??

Re: Change Z rod, and firmware

Here's my experiences:

My biggest problem was getting an M3 sized hole drilled dead center through a 5/16 bolt. My drill press skills weren't up to it, so I got the machine shop at work to do it on their lathe.

Re: Change Z rod, and firmware

You don't drill anything, you remove the existing z-rod, and replace it with whichever you are going to use. It's a ton easier with a metric threaded rod then it is with a standard. You use a coupler to go from the existing motor to the new z-rod. put it all back together change the firmware in printer settings inside of repetier and make sure to save the changes and your done.
