This first one wasn’t good enough, so one to the next one. That one starts further down this thread, https://www.v1engineering.com/forum/topic/updated-center-parts/#post-11784
All the parts printed a 55%, 3 perimeters, 2 bottom 3 top. All parts are printing better in my own opinion, screw holes all have more heft to them as well.
-3mm shorter in the z direction, but overall more z direction support, no longer offset.
-5mm wider in the X and Y direction, but the bolt heads don’t hit the rollers now so I think we actually gain 1-2mm.
- All bearings are spread further-more rigidity-the only flex I see now is the conduit. Smaller the machine the better more than ever now.
-No more support needed
-print volume needed 135x135x120mmZ
-ditch the 1.75" bolt, 4x3",and 1x6-32" +nut, in trade for 5x3.5". Easier assembly
- more adjustable, less tension needed over all
- Lock nut is dead simple, no more anti backlash. Hopefully easily adaptable for other lead screw options (not recommended but there is always someone).
-integrated knob/coupler. less hardware longer screws. better grip on the screw, and not torquing the screw should help not strip the coupler.
-beefier z grip, more true axis?
- any size stepper shaft.
- coupler is longer on both sides for better grip on the shaft/screw.
- prints much better, no overhangs
-shorter leadscrew needed
- Easier to switch tools. should be able to leave the mount on your tool of choice and un/screw easily from the front.
- more contact area, more rigid!
- longer contact with rails, more true axis?
- Pretty universal. All mounts will fit all 3 size machines. So if you make a mount you won’t need to make one for each machine. less fragmentation!
