It looks like the meet is on we have enough people interested. I wioll post a choice of dates hhere next week and see which works best. Thanks to everyone who has replied. Sorry for my delay in responsing. I have been out of circulation for two weeks - I think I said somewhere that the first part of May was v. difficult for me -- tooooooo many committments!!

A get together is being organised for late May/early June somewhere in the Bristol area.

A Regional West of England RUG is being formed. Hopefully members of Portsmouth_and_Havant RUG will join in. Can you pass on your experience to others & thereby help form more local groups in the region? In any case we hope to have a good time and organise some regional get-togethers Here is the announcement: _________________________________________________________________________________by vizion - Portsmouth / Havant RUG

I am planning to allocate time for this starting from mid-may onwards (pretty heftily committed until then). I am looking to see how much we could model on the PC standards system so I suggest anyone who is interested in this might want to familiarise themselves with the way in which that has grown and see what we have to learn from that process.

I would like to suggest that we start to think in terms of modules rather than models. Currently there is a tendency for us to have models e.g. Prusa which refer to specific whole reprap machine configurations. The alternative notion of modules offers a more flexible structure which would improve the opportunities for mutations. For example We have multiple solutions for the design of extrudeby vizion - Developers

Hi Any chance of improving the response time to requests to create User Group Forums? Thanks in advance davidby vizion - Administration, Announcements, Policy
You are echoing a discussion I have had recently with a few other people. IMHO head development should ideally be entirely be separate from reprap development with, as you suggest, a common multi-pin wiring interface. This means that as far as each tool is concerned the RepRap can be referred to as a host and the head becomes a device. Using this model devices could be controlled using USB 3.by vizion - RepLab Working Group

Actually his private comment mentioned 320k but he said "I'll say 640k for public consumption and none can object!"by vizion - General
I thought it was on topic - if one is programming a codec then the math capabilities of that program are very relevant to the codec. James also has taken my point up & replied showing an intention to include 32bit capability for position co-ordinates for the codec. So I respectfully disagree with any suggestion it is off topic for a discussion about a codec. Davidby vizion - General
OK where does one get nanoparticles of tin or silver?by vizion - General
Thanks will do. I am also looking at using aluminium extrusions for a rigid frame rather than a triangulated structure.by vizion - General
BTW Position co-ordinates 16 bit resolution. What does this imply for size of build? I am contemplating building a mega sized mendel but still require very accurate positioning. How easy would it be to go to 32bit floating decimal for long term scaling? I remember Bill Gates attitude to 32k Ram! davidby vizion - General
Bearing in mind increased loads I have been looking at the specs for the STP-MTR-23079 using the AVR-Based stepper motor Driver. Has anyone any experience of this combination? Thanks in advance davidby vizion - General
Thank you for the stewart platform idea - that make good sense and mirror for a laser is simple and smart solution. That leaves me looking for a spray head solution! Can you point me to a suitable design for the Stewart? I accept your kitchen sink advice! davidby vizion - General
Sounds sensible advice. For my purposes both the laser and spray head need to be orientated to point upwards/downwards and angled thru 360 degrees as well as in degrees as well correctly located in xyz axis. Finally they need to be able to find their way into nooks and crannies within the built model. So this implies extension arms/by vizion - General
What problems will I face scaling the mendel design to provide a larger Build Envelope. My ideal envelope would be 400mm x 500mm x 1400 What are the implications for the electronic control system? Thanks in advance Davidby vizion - General
Thank you for your offer of help it is much appreciated. My plan is to build the Mendel, test it to be working accurately before adding any additional components. I have been reluctant to start the build in case I could not achieve the additional functions. Without them there is no project. The laser diodes weigh a couple of grams and the spray material can be gravity fed using plastic tubes wiby vizion - General
I want to be able to add an additional head for the mendel for ancilliary processes to be applied when a model has been built. It needs to be a 6 way head which would enable the items it controls to reach inside a built model post build. The initial processes are 1. firing a laser 2. Controlling a miniature spray gun. I can think of a lot of other tools which could be used in similar ways. Canby vizion - General
