The Update....

I took my machine apart a few months ago followed by a house move; it has been a while since I played with the machine... I wanted to update everyone on current sate of things.

But first this is now the old version ;) working on a bigger and more rigid version. Never the less I didn't want to abandon this version and back ported many of the update ideas. This version did loose its aluminium t-slotted bed to its newer sibling :cry: ...

1) Moved to GT2 Belts and pulleys as this will have less backlash then MXL timing belt... see discussion here: http://www.shapeoko.com/forum/viewtopic.php?f=11&t=543
2) Moved all belts outside avoid loosing any travel for the workable area to belts idle pulleys.
3) Made better motor mounts, they are all nema23 with a nema23-nema17 plate at the end. Idle pulley hang from bottom nema23 screws, belt now hugs pulley better (more teeth touching pulley at same time). Link: http://www.thingiverse.com/thing:158778
4) I am now also playing with milling aluminium, for this I replaced the dual shaft drive to dual motor drive.
5) Moved all drag-chain supports outside of travel area (see #2)
6) Change belts anchors, I needed better adjustment control (using screw and lock nut to change tension). Link: http://www.thingiverse.com/thing:158789
7) Mod to z axis to make it more rigid, got rid of spacers. Parts are uploaded to thingiverse here: http://www.thingiverse.com/thing:158169
8) On X gantry collapsed space between rails to make room fro the z axis mod. Link: http://www.thingiverse.com/thing:158830

Very nice!
Love the work of plastic/hdpe into the build... I need to get on that as well...
Thanks for the post.

p.s. are you cutting these out on your other mill... or the shapeoko?

It looks great.

Did the spacer removing made any significant change in the rigidity of the machine ?
Can you please post a picture of your belt tensioner ?

1) yes it did, the z axis is much more rigid; have not done any PCBs to test yet but I can tell already it is much more rigid then it was before. The problem I am trying to solve is what I described on this other thread...
http://www.shapeoko.com/forum/viewtopic.php?f=11&t=922&start=10#p9287

2) For the belt anchor/tensioner is the same piece on all sides, just one side I add a M5 screw and a lock not to push against the mounting plate.

Is it suitable for printing in ABS/PLA, or does it need to be milled out of more sturdy stuff?

It will work fine, I haven't build a 3D printer yet (in the list, delta 3D printer) I am using HDPE, others have mention using MDF. just wanted mine to be impervious to humidity and other such elements. You could be the first to let us know. If you look, most of the parts are there to support other materials like aluminum, only the belt anchors are actually doing any real work.
