This project is the experimental continuation of the #Coffee Maker Delta 3D Printer, aiming for greater build volume and finer print resolution.
Initial improvements include longer arms for greater build volume and gearing down the motors 5:1. More improvements to follow.
This project is slated for an eventual collaboration with the #Mechaduino project, bringing you a 3D printer with closed loop true delta style kinematics. That's right: no more skipped steps, no more endstops.
The long arms in the delta mechanism amplify the quantization from the stepper motors, resulting in ridges on the surface of printed parts. To combat this effect and increase print resolution, we added 5:1 gears to the motors using GT-2 belts. The roughly designed prototype:
This modification was a total success, there is no discernible "ridging" from the motors anymore. The new mechanism in action (but out of frame).
The initial build was merely a larger version of the #Coffee Maker Delta 3D Printer, with longer arms and without the physical constraints of the coffee maker (or the charm).

Success! A working printer!
Love this! And the fan in the mug makes that photo so much cooler.

Hi, could you say something about the firmware you use?
Thanks!
