Re: Building a 3DR "Simple"
Hmmm. I just re-read that blog post on configuration and I think I've been going the wrong direction with my adjustment of smooth rod offset... Lemme try again.

Quotebrendanjerwin Alright, I'm at a bit of a lose here. I'm trying to get the delta radius set but things just aren't making sense. With these settings (I know, horrible things done to the smooth rod...

Good news! By carefully reading the blog here I was able to get the heights at all 4 points pretty damn close. Thanks jaydmdigital for that. I was adjusting in the wrong direction, that's why things...

OK, first print happened! Decided I needed to wire up the fan, but it didn't work. After some research I found that I needed to set the fan pin to 16 instead of 22. That fixed it.

So I added heat syncs and fans and dialed back the drivers. That solved it, super smooth. Now if the pla and Bowden tube I ordered would show up...

E steps / mm were way off. Seeing as I just stole some values from a random repository of AirTripper's I wasn't surprised. Measured and set them more correctly at 97/mm. That'll do well enough to keep...

Here are the numbers that I get directly from my SolidWorks files: #define DELTA_SMOOTH_ROD_OFFSET 133.54 // mm #define DELTA_EFFECTOR_OFFSET 22.87 // mm #define DELTA_CARRIAGE_OFFSET 16.5 The first...

Now that is just weird. I printed a 50mm tall tower. The first ~14mm of it skewed toward my Z tower but the rest of it printed pretty well true. I wonder if that might actually be something with the...

Thanks JohnSL. My calibration was heading toward that number (I was .5 off). I'll try again with exactly that number since I'm pretty confident in the quality of my parts. I see that my z tower top...

Another thing. I slowed down my homing speed even more. Now its 70*60. I think it might be knocking the end-stops too hard and messing with the height calibration.

After adjusting the Z-Tower top to be the same height as the other two, the skew problem has gotten better, but not eliminated. Now what I'm seeing is a slight amount of skew, still towards the...

My base has morphed a bit: [attachment 25725 fatmid.png] It still fits through the ever famous door. It's optimized for motors and electronics above the mid plate. More or less - no more bottom plate.
