Jeff,

There are quite a few postings here on that topic. http://www.machsupport.com/forum/index.php/topic,13859.0.html

Perhaps if you PM Khalid he may be able to give you more details of his setup and software.

Hi Jack,

I think you need to tell the A axis which direction to point within your GCode. Would something like this work ?

Richard,

You are on the right lines.

The Macro Pump runs in the background and could control the functions you require with your VB code.
Here is one link but there are many if you do a search  http://www.machsupport.com/forum/index.php/topic,13576.0.html

Terry,

Thanks for the suggestion but if it's what we call 'Icing Sugar' here in the UK, then yes I did try some but it caught fire instantly  :o :o

In general the 'air assist' tends to extinguish combustion in most materials before it starts but I have this set to an extremely low level when working with powders otherwise the stuff just gets blown away.

It is perhaps interesting that photocopy toner does not ignite (at least the stuff I have didn't) and this must have similar particle size to powered sugar but it did not really produce the desired results - perhaps a mixture of the two may work ?.

Lots of possibilities to try - please keep the suggestions coming Guys - I do appreciate your help.

Excellent work Chris, a well prepared document which I am sure is extremely useful to us all.

Hi Gerry,

Perhaps in my dreams, but I think that is a little ambitious for me to start with. Maybe a little Torus is more the mark  ;D

What I want is to put a button on my screen to turn on and off my output 2

I seem to have missed something here - surely Hood has already given you the information you need to do just that.

Add a VB button to your screen then within Mach paste in Hood's VB code and away you go - Output #2  toggles  ON / OFF.

In some ways this is a continuation of ‘The Laser Project’ but because there are many ways in which 3D Printing can be achieved I thought it perhaps deserves its own thread. The method I have decided to initially follow is that of Selective Laser Sintering. http://en.wikipedia.org/wiki/File:Selective_laser_melting_system_schematic.jpg

My initial model is only 2D (about 3mm thick) and was produced in just two layers using a simple stacking frame – this has, however, given me sufficient confidence to start building a larger frame or jig with a moving Z Axis base that will allow models up to 60mm deep to be produced on my existing machine without any additional modification. If this is successful, who knows?
My initial inspiration for trying this came from the Candy Fab project and more details of their progress can be found here http://candyfab.org/

Although I accept that the quality of my initial model is not very good I think that by using fusible materials which have a finer grain structures things can only get better.

I would appreciate your comments / suggestions relating to this or 3D printing in general.

Evan,

If you wish to toggle Output #2 from within a GCode program :-

The command M50 doesn't seem to get used anymore so by placing the macro Hood has given (minus the Hood line  ;D ) in the macro 'M50.m1s' (delete or rem the stuff that's in there already) then by placing M50 in the GCode this will toggle output #2.
