I've read of others using belt systems for Z axis without issues, even reports of it eliminating Z-banding. I think I'll go with this arrangement...
One thing I'm thinking of is to ditch the threaded Z-rods (I'll use them for something else..) and instead use a belt system on each side of the Z...
New plan: Architect the frame for the build volume I want (400mx3) rather than arbitrary 500mm V-Slot lengths. This required that I make...
Decided to go with the CRAMPS board for the BeagleBone Black, with LinuxCNC. Ordered one, so it'll be here in a few days - not that I'll need it...
And here's the belt layout for the underside, viewed with the build plate hidden. I rotated the vertical beams 90 degrees, so the stepper needs...
Placed the idler pulleys required to make the top half of the CoreXY belt loops, and sketched out the path. The belt will be attached to the belt...
Yeah, I realized that after I started lining things up. The alternative I'm going with now is with the top beams laid flat in a square, with the...
The new gantry and side rails are more likely to be like this. [ATTACH] The side rails are rotated horizontally, with the gantry wheels riding...
Yeah, I plan to turn the side rails onto the horizontal orientation, just haven't modeled that part yet.
So, this is an alternate carriage that I've mocked up, using the newer 20mm gantry plates - thanks to TomH for the idea. :) Needs some work to be...
Also: I see what you mean, with the use of the new 20mm gantry plates. That's an interesting idea - I'll see if I can incorporate the new 20mm...
I believe they're listed as just the "XY Idler - Right" and "XY Idler - Left" STL's - they're the (extended) pieces that go in the back corners....
I'm not sure if I've seen your mini v-slot gantry plate - if it's not in this thread, a link would be appreciated. Or if it is, a post number. :)...
The fixed bed idea is rather neat - I haven't cut my rails yet, so I may try to incorporate that somehow. I've been experimenting with using the...
The Replicape board is the one I've been watching, good thing the price dropped from $179 to $99 - though I'm going to wait for the Revision B...
Time and money - but mostly money.
I played around with the design for this for a while, but ultimately decided to shelve the build for the foreseeable future. I have no plans at...
Not exactly - SmoothieBoard has A4982 stepper drivers rather than the DRV8825 stepper drivers I want. I'm keeping an eye on the Replicape board...
They're simple Sketchup components that I'm intending to print. The bed and mount designs are still in flux - I'm considering using a sheet of...
I've made a design change to the Mini-V Gantry plates that serve as the Z axis ends - by removing two of the wheels and chopping 15mm off the side...
