As /u/Phil12312 pointed out, the brass coupling should have it's screws a little loose.

You may have a burr on the leadscrew that doesn't "move a little faster".

Try moving the leadscrew using the 1mm setting from the bottom to the top by hand see if you can spot it.

If there is a burr, you can smooth it by hand with a piece of fine (400 - 600 Grit) silicon carbide sanding paper.

Lubricant - \u\Dylanator13 's suggestion of 3-in-one Oil is just plain WRONG. (Sorry, Buddy! :-) )

It's fine that you used what you have handy, it's your machine. If you choose to mistreat it, that's between you and your machine. But PLEASE don't recommend this to anyone else, it's just wrong!

"There are many different suggestions of what lubricant to use online" - Yeah, and the majority of them are the blind leading the blind. Threaded rods need a fine GREASE, not a light OIL that breaks down quickly, and can run down the shaft fouling the stepper motor.

The proper lubricant for a leadscrew is a VERY THIN, EVEN application of either a Lithium based grease, or what many have found superior, a heavy duty PTFE based grease like Super Lube.

It has excellent lube properties, has a very long breakdown time (unlike many greases), and isn't prone to attracting dust which wears bearings.

But I got mine here in the US at Ace Hardware (was actually MUCH cheaper!) :

If you're in Europe, UK or Australia, I don't know where you can get it, maybe someone can jump in!


Let us know if you solve it, K?
