Re: 3DR "Simple" Delta Printer
I built a 3DR Simple without a Printrbot Simple because I could print all of the parts on my Buccaneer. The printer I built is pretty tall, with a maximum build height of around 43cm: IMG_6439.JPG...

One issue you may have would be the resolution you get by direct-driving steppers like this. In the image above, the driven arms rotate over about 180 degrees. Given your average stepper does 200...

Thanks, I was sure resolution would be a problem with this design, apart from that I can't see any other issues. If it comes to it, I may well add a set of gears to increase resolution, but this...

You still need to hang your arms somewhere stable enough in relation to the rest of the frame. I dont see any advantage in this hybrid, apart from the nightmare youll have when start mixing parts of...

Flip it upside down. There is no need to waste a big rigid frame on a 3D printer when you could just mount the motors down low. Think: 2 armed GUS Simpson. The table could be a conventional Y or you...

@nka, I picked up an E3D v6 hotend as well, and am looking at how I plan to fit the fan. It does look like it could fit where you suggested, but that would cover one of the screw holes for a spring on...

I have that exact setup with a JHead. It works fine. You will find one decent spring on the other side is sufficient, or, alternatively, a rubber 'O' ring works great too! To save wires you can run...

Thanks for the input guys! I'll look at flipping the delta mechanism, it's exactly the kind of suggestion I was looking for. I'm certainly sticking with shoulder actuation, and I'm interested in your...

Just to be clear... A GUS arm is elbow actuated. One neat thing about the GUS arm is that it has a linear response. You can think of it as a linear actuator. That makes the firmware calculations deal...

If you aren't going to use belts, strings, or lead screws then you don't really have a lot left. I am not aware of a fully printed solution that would be backlash free and would get the 1:50...

All right, well sticking to the inverted 2 axis delta idea seems like an option, do you think it is? As in, would it work? To my knowledge, it would only have are resolution issue. If not, or even if...

RDGUS adds a lot of costs so I would put that on the back burner. The next generation GUS arm that I am going to release in the next month would be my top pick due to the mathematical savings you will...
