Re: New arm design for Simpson style printer.
Very interesting rope info. I always use the flake method for dealing with my vacuum cleaner cord, but I never knew to call it that. Sometimes I wind line around palm and elbow crossing over midway to...

Thanks. I call it the "Simple" because I'm going to use a lot of the hardware from my Printrbot Simple to build this printer. But as you say, I can publish multiple versions of the parts, which I will...

Re: 3DR "Simple" Delta Printer
While I wait for my parts to arrive, here is how far I've gotten with the design for the top and bottom parts. I'm showing images from underneath these parts. The bottom is probably close to being...

Re: New arm design for Simpson style printer.
The adjacent article to the bending radius describes how to design a pulley (sheave) for braided line. The diameter of the pulley is 8 times the rope diameter, and is mated to a round grove in the...
View ArticleRe: To to ensure Hot end is perpendicular to the bed?
In slightly clearer terms, the arms *must* be equal length AND parallel to each other. Even a slight non-parallelism between a pair of arms can cause the effector to rotate about the X or Y...

Nice work, HaDe! Very clean build. I didn't even realize that it makes more sense to tie the Spectra to the right of the carriage instead of the left as the directions say. Did you need a tap for the...

I'm not able to locate a BOM. What is the source of this idler bearing and the RepRapDiscount Hall effect end-stop? Missing link: 3 x Hall effect end-stops (I'm using RepRapDiscount versions, here)...

View ArticleRe: To to ensure Hot end is perpendicular to the bed?
Hi! Yes, I understand about the equality of the arm lengths. I was mainly thinking with a handmade DIY delta, the J-head extends 3 inches or so from the bottom of the end effector plate. I bet a 1-2mm...

Next question please. As you have printed 3DR_Bottom_Motor_Mount_V2_001_RTP.stl you hadn t any problem with the alu extrusion. It did fit ? If yes, which PLA did you use? I am fighting since one week,...

At first I thought it wouldn't fit, too - but after removing some artifacts from the (although fine and well calibrated) printed parts - effectively making chamfers on all edges where the extrusion...

Many thanks, now I know I am not alone. So you dressed to size the printed plastic part and the aluminium extrusion. I mean you sanded them, right ?

Ah ok, now I understand the central point of your question ;) Well, I'm sure that someone can argue otherwise, but I would say that there are more important things to worry about on a Delta that...

I don t think it will be enough in my case because I have at least + 1mm. I will have to redesign the part, cause I want to be able to disassemble the printer when needed. Ok thanks a lot for your...

what aluminium profile are you using ? , the printed parts are designed for Bosch-Rexroth (BR) profile, using different profile would explain the size discrepancy

Hi Richard, I'm really impressed by your 3DR design. Where can I have the plastics parts printed? Could I buy them from you? Thank you in advance.
