... good luck! - when I first time calculated the positions for my 'magnetic-spheres-joints'-tripod in 2007 this was a trigonometric 'mess', but then found the simplicity in pythagoras based on a...

Dave, did you find a solution? I have exactly the same problem; triple checked the geometry . . cant find any issues.

Here is the bill of materials. I am not going to stick to this exactly. For instance, I will use a 12"x12" heated bed but it is more expensive than the 8"x8". This also doesn't include tax and...

What firmware are you using, Repetier at least has a bug in it, the steps/mm must be set correctly both in configuration.h AND in the EEPROM settings. If they do not match you get weird motion, the...

Re: Grounded Experimental Delta Printer
I finally figured out the work envelope. Each arm can drive the extruder from 3.568" to 15.259". If you do an intersection of the allowable zone for each arm you get this. The usuable envelope that...

Hello! First of all, nice work! I think all this talk about having to have a simple math is irrelevant. One can write a script to convert the xyz paths that the slicer prints out to whatever geometry...

"Suffice it to say that it's not even relevant since the architecture with the simpler math is simpler to build and calibrate too" That's the real reason to build it this way, I don't think one should...

@alagi: I am using this spring. I have actually already received the parts and they are stiffer than I hoped so I had to make some hangers to shorten the needed spring extension. I will have to run...

Wow, I wish I had known that sooner... But my eeprom should contain all the values found in config.h as last time I compiled I used a <>0 besides one, which forces eeprom to be overridden And to...

Rostock firmware, uneven extrusion
Dear fellow Rostock owners, I just made this post about uneven extrusion (from a firmware bug I believe) in the firmware forum. -Before realizing there was a seperate rostock/delta forum. Maybe you...

Simpson lives! This is the first (documented) dry run of Simpson. A RepRap 3D printer. There are some visible issues. The extruder will pitch and roll causing the extruder tip to be as much as 5mm...

Just wanted to say: cute Rostock you got going on there :) I am almost ready to build my own. Currently owning a Reprap Air 2, but I like the simplicity of the Rostock. Do I see it correctly? Are you...

I've been following this thread for a while and I am impressed with how quickly the prototype Simpson came together. Great work Nicholas.
