Okay, I seriously had to take a break from this to get my head sorted. I came away with one really important thing: before going insane and rewiring everything because something doesn't work, check that everything is there. How did I come to this mind-blowing notion? I took a break, stepped back and double checked my mendel only to notice that I had forgotten to put the stepper drivers on the PCB and that was causing my motor issues. It only took nearly a week of Adderall-fueled rage and confusion to figure this out.
So what has happened in the couple of days I took off? Not much except for my significant other's frantic call to me yesterday to say that there was a tiny stray kitty two blocks away that he needed to rescue. Other than that good deed, I have some (really) rough sketches of some of the components for the delta bot. Tonight, I plan to finalize the sketches into something actually resembling parts and not a bracket with a face. Let's wish me luck on my first attempt to create an .stl file!
Here are the part(s) I'll be working on tonight:
- arm segments
- Extruder carriage (although I have seen a number of really nice designs already being used)
I'm really interested in trying to find an adapted, printable version of the timing belt. I've seen this discussed on the RepRap forum and am really interested in people's efforts to get around this part of the machine. So here's my weekend quest: Find a suitable replacement for the timing belt or some sort of adaptation of it. This is tough since you can't really print a timing belt in ABS. Well, you can, but it wouldn't exactly function the way it would normally. I guess it would be more akin to a track than a belt but whatever.
Happy weekend, readers!
