Re: 3DR "Simple" Delta Printer
JohnSL, My need for files is no longer. I was having issues with some of the bosch profile pieces staying stuck down initially. I have since upgraded the Cupcake CNC I am using to a stepper extruder...

I collaborated on a paper with Ilian Bonev (one of the tripteron's creators) that covered what he calls the Hexapteron. (I am still on the fence about going with this name change.) He is having one of...

The original LISA prototype was a success. She was such a success that I have no plans on taking her apart to reuse the components. (My original Simpson design has long since been scavenged.) As far...

Looks cool! 1) When you womp the big circle out of the middle plate, you reduce it's stiffness a bit. Do you think it still will be good enough to keep the screws all in line? 2) You can print the...

To really do the tension right, I suspect you need a spring to compress the cut end of the nut. With a static adjuster (like a NPT bushing) you are depending on the flex of the nut to ride out the...

Quotenicholas.seward once there is a cheap enough controller that can handle this. Is the arduino mega 2560 not powerful enough? Arduino Due with RAMPS?

John, what files should we be printing out for the top? There is a top mount file in the "simple parts" folder but then there is the whole top folder.

Do you like the fan duct? Can you compare it to simple fan (mounted on platform without any air guide)?

Let me rephrase. I know that there are solutions. I am waiting for the total electronics solution to drop under $150 and require no electronics work on my part. I have very good reason to believe that...

My guess is that you would have to play a bit with springs and tapers. The data for that nut shows they cut the load rating from 90 lb down to 25 doing what they did. That suggests they are doing some...

@uncle_bob: 1) I suspect it will be stiff enough. I am considering doubling up the plate as a backup plan. However, the top and bottom plates will probably give me the rigidity I need and the mid...

By total electronics do you include PSU, heatbed, steppers, hot end? Otherwise Due + RAMPS-FD plus pololus is around $150 already. I'm looking at replacing the Due with a Cortex M4 at ~200MHz with...
