Here's the STL files for the belt tensioner assembly...
Carriage mounted belt tensioner: I was inspired by this one: Belt Tensioner/Clamp - Precision by rbilbrey With this finished, I will proceed...
More progress - and 2 new STL files. I got the diagonal braces installed and found they make a very noticeable difference in rigidity as...
Progress! And now starting to print the diagonal brace parts. Looks like around 17 hours of printing for those 8 parts. [ATTACH] [ATTACH]
Thanks! Upon finding this Delta-6 build page I really liked a few things in the design so I decided to build one for myself and look for ways to...
Curiosity may get me here regarding what, if any, improvements my added bracing will provide in terms of stiffness. I have a large welding jig...
I just checked the NEMA17 bolt pattern on my vertex and it is correct - 31mm square pattern as shown here
I pulled that NEMA17 pattern out of another part file I had.... let me double check that I did not somehow use the wrong pattern - but what you're...
More rigidity overkill - maybe too much? It's only an extra couple days of printing parts and a few $$ more in extrusion - so I'll probably do it....
ok.... I should have waited to post this spacer with the assembly - should give me enough clearance for the effector anywhere in the build area....
Forgot to mention that I plan to offset the diagonal braces further from the frame using some sort of spacer - need to make sure I have enough...
Oops - realized my chamfered edge on the end was not symmetrical - fixed now: [ATTACH]
More enhancements - diagonal bracing: Starting with this end piece for 20x20 rail (I will upload the STL after I print one and make sure it is...
As a learning exercise, I did my vertex drawing in OnShape. Anyone can copy/modify it easily there.
I used SolidWorks to draw them. I very briefly looked at openscad but don't have time to learn it anytime soon and since I use SolidWorks very...
My horizontal extrusions are 530mm long and my rods are 501.25mm. I ran my dimensions by some knowledgeable people in the google deltabot group...
Time for a sanity check.... Does anyone see anything too far off with my numbers, angles, etc? I will use a 400mm diameter heated bed. I already...
Another design improvement for more rigidity and the STL file to go with it: [ATTACH] [ATTACH]
Thanks for the compliment! Here it is printing and finished at 0.2mm layer height using eSun solid red PETG at 100% infill. I'm printing another...
Kyo, here it is.
