Hi Ed, ... sure, Starfarers of Catan isn't a combat game (you have only occasionally to battle against pirates so you're seriously interested in enhancing your drives and guns ) but some of the gaming mechanisms and developing of the universe, paths and bases could possibly be adopted.

Hi Neil, i'm on a repstrapping 'sidepath' with ataching a syringe-extruder and diodelaser-fibre-optics beside the mill-head on a 3-axis CNC-mill. This is meant for dispensing fluid pastes at room-temp through thin syringe-needles and curing or cutting resins and plastics. My smallest dispenser-setup has needles with inner diameters of 0,06mm for low-viscouse pastes - here i want to fab with UVby VDX - Plastic Extruder Working Group

Hi Neil, printing wax is an extremely complicated and expensive task. Especially for jewelry apps you need very accurate surfaces so you'll better look for CNC-milling - here you have much better results with cheaper machines as you don't need the rigidities of metal-working. With two-sided milling you can make most complex shapes and details. Only for very complex forms it's in comparison betby VDX - Plastic Extruder Working Group
... i'm a big fan of "Die Sternfahrer von Catan" - look here for some details: It's a board-game with some similar aspects - hexagonal tiles, interactive development of the univers and game and some randomly defined action-elements with selecting ressources, event-cards and such. Maybe you'll find here some good ideas too? Viktorby VDX - Let's design something! (I've got an idea ...)
Hi unfold, i did some lom-fabbing with lasercut-steelfoil (see here: ) and knife-cutted ceramic green sheets (from DuPont chemical) for developing and manufacturing microsensors - or search for "viktor laminated" in "all dates" ...

... some 20 years ago i did ( ) some "photo-plotting" of PCB's with light-sensitive coating and a green LED (no UV-LED's then ) - the main problem was finding spray-coating with the right sensitivity-range for green - the single vendor didn't survive very long ...

Hi dries, i built a simplified paste-dispenser - look here for some images: It's meant for small volumes (10ml-cartouche with ID-0,15mm-needle for fluid PMMA) and high accuracies, but i have the parts and threads for 50ml-cartouches too.

Hi Brian, no question - one of my most favorite mottos is "keep it simple, stupid" My interest in higher accuracies is more private as i'm going a sidepath of repstrapping in direction of microns-resoultion with fabbing and reworking with different technologies.

Hi Annirak, i solved a similar problem with two toolheads and exchangeable millheads or syringe-needles with a webcam in a corner looking upright with a crosshair in the monitor. Adjusting the Zero-start-position with an accuracy of nearly 0,01mm in XY and 0,1mm in Z was made by moving the actual tool in the range of the camera and fine-tuning in X,Y,Z until the tooltip was in the middle of theby VDX - General
Hi Fred, i think the RR-extruder on a f@h-printer is no big deal: - you have to handle the speed of the extruder-motor with a DC- or PWM-signal and the moving speed of the head in relation to extrusion. In the other directon you have to hack the thermistor-signal (simplest with a discrete resistor of the 'good-temp' value) and switch from the GM3-DC-motor to the dispenser-stepper-motor ...

... automated 3D-foamcutting isn't so simple as manually because of randomly concentrated blobs of pure PS -- the foam didn't really vanish, but is only melting away from the hot tool and forming small strings and blobs of PS which when cooled down need more heat or slower motion to remove properly.

Hi Forrest, actual working GA-samples would be interesting for me too. 20 years ago i made some 'traveling salesmen'-optimisation with a neural-network-chain for CNC-drilling PCB's on my Atari-ST and hoped to develop a 'self-trained' perfect 3D-CNC-controller, but then my diploma examinations went hot and i somehow lost contact ...
