New Z Parts

Postby bdring » Tue Jan 22, 2013 11:47 pm

I prototyped a variation of the Z wobble fix that many people have made and it worked out quit well. This is cut from HDPE. I used machined HDPE because it only takes about 1 minute per on my router. The HDPE on Delrin is super smooth so that helps. I really like the soft head-crash feature it adds as well.

I have a couple hundred nuts on order and I will sell these as an upgrade. I will sell them at very low cost (with free shipping) because this was a community designed upgrade. The BOM and drawings have been updated with this part (B17060). They will come with the nuts installed . There is a right and left hand in the kit. You just need to pop out the nuts in your existing piece. do it slowly and carefully so you don't crack it. The kits will go on sale early next week.

The BOM also now has a new nut-less Z block for future builders.

Here is a picture. This one is actually a reject because it broke lose and the tip got wacked by the bit.

Sign me up for a set. I'm building mine from parts... So I was wondering if you have a spare set of original nuts to go with it, or able to print something that could work?

Thanks

I'll list the nuts too, but I need to get past ORD Camp this week end.

I have an original production run Hadron. When I install this, I need to ream out the threads in my Delrin nutblocks to make the Z lift blocks, correct?

Drill threaded delrin parts to about 9.5mm in diameter. Break the edge a little if there are any burrs. on the bottom side so the surface is smooth.

As an alternative - in case the original part would be reused in the future - you can try the Z-AxisBlockV2:

I liked all your parts on Thingiverse yesterday. :) Ever since I took my original solid couplers off and tried to switch to flex couplers(which was the current fix at the time), I've had horrible wobble and just stopped messing with the machine for a few months. Now I'm catching up to the latest stuff. If I'm going to take down the whole axis and rebuild it, I might as well switch to the metal nuts version. My Delrin nuts are pretty loose already.

@Zat German

Thank you for your feedback on Thingiverse.
I didn't try the metal nuts version yet but probably a bronze nut will be the best combined with the stainless steel threaded rod.

There's also a new topic: http://buildlog.net/forum/viewtopic.php?f=27&t=1856

OK, since I've received my kit and the nuts weren't installed, I'm going to need some instructions, or, in my ignorance, I'm liable to do some damage using my usual "HULK SMASH" installation technique. Unless brute force is all that's called for, that is.
