Most likely by "I printed this design". In anyway most likely that's only me who made it :)

How do you see if others have made this?

This looks great. I was just considering making RIch's Slider printer and i think this will help me tremendously. I look forwarder to adopting some of hour idea.

Hi,Thank you for showing interest in my design, and sorry for long delay w/out update. I'm going to dedicate more time for this project this weekend, so I expect I'll have better progress on that. For now just a few changes on design (updates are in description).

Any further updates?

@Bearwood in theory yes, but my Z axis precision is 0.01mm. 360 / 1.8 (angle/step) = 200 steps to move around. In one cycle Z axis moves 2mm. 2mm/200=0.01mm My biggest concern using this type of axis was what weight this axis is capable to move. I just did a test with 2.6kg moving up and I didn't have any issues. If you have z-wobble it could be solved making Z axis loossly coupled to the bed like in MendelMax design (check page 42 https://docs.google.com/document/d/1xkqIbNjqopCkrOkwJX_i-BKoRBu3syexM9-6eJNrW8o/edit). I didn't see any visible wobble, but I'll check later with micrometer. Tomorrow I'm leaving for my one month vacation, so I'll update with my status in April.

<a rel="nofollow" target="_blank" href="/users/Gediminas" class="mentioned-user">@Gediminas</a> In theory the geared stepper and spectra will give a finer resolution. Also like <a rel="nofollow" target="_blank" href="/users/sgraber" class="mentioned-user">@sgraber</a> said you don't get the z-wobble/sync issues. Plenty of others are using belts to great advantage so keep going that road.@sgrabber I have been looking at lots of ideas over the last wee while but I keep coming back to this one. I need to settle on an idea and run with it but my current printer keeps having issues which diverts my attention :-(

@Gediminas: Part of it is to preserve the Sli3dr design, the other part is that I've grown tired of diagnosing / fixing z-wobble.

@Bearwood @sgraber, what is the advantage of spectra driven Z-axis? I'm just curious maybe I'm missing something choosing lead screw.

Mount 6mm shafts in XY carriage is very weak.and possibly shafts X and Y should be placed in the same plane. 6mm shafts should be lowered down to ~7 mmsomething like this: <a target="_blank" rel="nofollow" href="http://i62.tinypic.com/2m08dz.jpg">http://i62.tinypic.com/2m08dz.jpg</a> or like this: <a target="_blank" rel="nofollow" href="http://i62.tinypic.com/290rmsw.jpg">http://i62.tinypic.com/290rmsw.jpg</a>

@Bearwood: I'm with you. I'd like to backport the original spectra driven z-axis into this design. Have you started working on it?

I do expect to get flanged bearings for Z-axis in a week or two (china post is very slow). And then I will approve/improve this design. Basically it works for Ultimaker, should work fine here too.

Nice clean look. I'll have to think about adapting this to the original spectra driven dual supported Z axis.

Yes, I was thinking to convert to 8mm too, but later decided to give a try to 6mm. These rods only 315mm long and carriage is not really heavy. So I think it should be fine to go with 6mm. 6mm x2 rods weights 140g, 8mm x2 rods weights 250g, so it's 44% (110g) lighter in rods only (plus 4 bearings). That's the reason for me to try 6mm rods. BTW, help is always needed. For example reviewing design and improving it! :)

Any way I can help?Edit: I've updated the XY carriage and smooth rod holders to M8, which might help.
