Re: New arm design for Simpson style printer.
I banged out some math real quick. I will have to revisit it to verify that I am not blowing smoke but here is what I think the gear ratio needs to be with respect to the angle that the arms make with...

Here is a better visualization. Each movement consists of the red cam rotating 15 degrees and the arm ends moving 1 inch away from each other.

Have you printed the three top electronics mount parts? It would be great if you could post the weight :-)

So all bits have arrived, and only a couple of parts left to print (top & bottom hub). My F5 button is really starting to look heavily worn now, can't wait for Part 2-5 as everything is nearly...

Guizmo, Nicholas Seward: I like the combination of the zero back lash of the Double Lamina Compliant Joint (DLCJ) bearing/joint, and the non linear toothless elliptical gear or cam correction as it...

Do you have any estimate of how long it would take to print all parts?

Hi, it depends on the your machine, I made up 11 plates and If I remember correctly I did it over 7 evenings and a weekend.

Depends on your build volume, which infill you use, infill %, number of perimeters, layer height, extrusion width, etc.

I realized I'm wrong. The center of rotation moves on a DLCJ. I have to calculate.

Do you know the hair spray trick for PLA? Aqua Net Hairspray I can't hardly get my prints up it holds so well.

Re: New arm design for Simpson style printer.
I believe we can design a hybrid between the DLCJ and the non circular gears, infact, it would be a DLCJ with variable ratio, allowing us to eliminate the bearings and at the same time working like...

One interesting note about the DLCJ is that it would not be great at constraining things sideways. However, sideways shifting of the joint won't change the driven dimension therefore it won't matter...

Two other notes, this can make both of your parts symmetric and you can drive it from the top which will let you get rid of the spring. :)-D
