Wallace++ (M8 edition) by sponnet Mar 27, 2013

Description

An enhanced version of the Wallace 3D printer.
Features a more stable X-carriage construction which balances the extruder body over 2 horizontally mounted rods. It uses less screws & bolts than the original Wallace.
Some features :
* Y-mount.stl & y-bearing-guide.stl : An enhanced mount for centering the Y-axis belt. Gives you a more stable pull.
* X-end2-motor.stl + X-end2-idler.stl : new motor mounts, align the X-axis horizontally
* X-carriage.stl : carriage for the horizontal setup. Fits a wade extruder & any type of hotend, even the newer short JHead extruders...
* base_end_2off.stl : enhanced base - puts the linear bearings as far apart as possible to enhance the stability of the print bed.
* y_bearing_retainer_stopswitch.stl : bearing retainer including a ziptie stopswitch mount, for your Z-stopswitch.
Update 20130430 : New Y-mount & bearing-guide uploaded.
Update 20140809 : Removed obsolete parts

Hi, I double checked the SCAD file , the diameter of the bearing holes is 15cm.
I added a ZIPfile with all the SCAD files so you can verify / adapt to your needs. The parameters are in wallace2.scad
Let me know if it worked... If anything is unclear, let me know.
The bearing holes in x_end2.stl and x_end2-idler.stl are still 14.5mm in diameter. LM8UU still won't fit.
Oh this is nice ! Thanks

Instructions

1. Print these :
- 2 x base_end_2off.stl ( base )
- 3 x y_bearing_retainer.stl
- 1 x y_bearing_retainer_stopswitch.stl
- 1 x X-carriage.stl
- 1 x X-end2-idler.stl
- 1 x X-end2-motor.stl
- 1 x Y-bearing-guide.stl
- 1 x y-mount-nema17.stl OR y-mount.stl : use the nema17 version if you want to mount the stepper motor directly on the Y-drive , use the other one if you want to mount your Y-motor on your printer base.
2. Additionaly also print these printrbot parts (http://www.thingiverse.com/thing:16990)
- 1 x pb-BeltClip-x2.stl
- 4 x Z-Coupler.stl
You can mount your X and Y endstops on the smooth rods using this thing : thingiverse.com/thing:64254

Could you please provide some more photos so the assembly is easier ? Maybe the bottom part which is left out in the photo you've made.This would be really appreciated ! Thank you !

Also I have problems getting the LM8UU bearings into the holes in x_end_motor.stl. The hole has a diameter of 14.5mm and there is no scad file of it. Does this mean I have to grind until it fits ? Maybe this edition needs some overhaul so it actually works out of the printer...

I just finish install of this update to my printer, however hotend is close to my PLA printed carriage - I think it can have issue with temperature being too high. Do you have fan on your machine?
I did a fan mount from steel sheet, cut it out and bended to fit. Good for now
What parts do I use for the X belt Idler? Thanks
The file is missing 4 of the stl files : /
y_bearing_retainer.stl and y_bearing_retainer_stopswitch.stl give errors in Slic3r (the latter has a hole reported on import, the former also and after processing has overlapping or self-intersecting facets,...)
Is this a known issue that doesn't cause any (real) printing problems ?
you can check & correct the STL with a free version of netfabb. I'll try to upload a new version here.
I've uploaded repaired versions of the y_bearing_retainer.stl and y_bearing_retainer_stopswitch.stl - the manifold errors should be gone now...
