Zain experiments here:
Starting Point
Long X Run+3D Scan
Pumpkins
Clay
Continuous Roller X Axis
Remote Making: In House
5 Axis
SmoothieWare Controller
Dual driven X Axis use external drivers in parallel
B and C axis gear reduced nema 17s
Belt drive on Z Axis also need gear reduction
Still have to add end stops for all axes
Super Tiny Spindle Design Belt Drive
Then Crown Pulley and Z Axis Lead Screw Redesign
Using Mastercam + Generic Fanuc 5x Post for Gcode
sim here
Machined an aluminum version of Clank Slide; no flexures
Use Jens Offset Cams for Bearing Preload instead, super awesome
Don't use BB Plywood as an X Axis Table, it swells on humid days
Use Jake's Clamshell Rotary with direct drive nema17
Will switch to belt+pulley version probably
Spindle Testing
Try to make a clank spindle, run off YEP 40A ESC + TinyG PWM
First Use XING 2207 1800KV, runs ok, but easy to stall motor.
Next try PropDrive 35-42 1250KV, can take heavier cuts
Need retention on fasteners, and stiffer machine
With M3 S1800, spindle runs at 18000rpm and ~16000 under load
1/4" Tool 1/8" DOC and 1/16" WOC 4-6 IPM sounds....ok...
Desk Mate
Machine Learning and Computer Vision Enabled Drawing Machine
50yard x 12" Trace Paper
Encode a drawing, project into a latent space in R2
Perturb the drawing's latent representation and draw something back
Still working on it....
Kuka experiments here:
Liquid Metal Printing Experiments
Super fast and sort of controllable molten metal deposition
in a sandbox of 100ish micron granular media
A-Axis plug rod to modulate flow rate forthcoming
So far printing flat objects, like
this chair frame
Trying to simulate granular particle and fluid interaction with
nozzle output shaft as a moving boundary condition
Still working on simulating
