The components will be fabricated and even prewelded in few spots just to hold together before my machine "gets hands" on the part. Taking a look at those shapes I definitely agree that those lines are ellipses. 2011/6/4 Stuart Stevenson <stus...@gmail.com>: > Are you looking for welding motion? If so what is your timeframe?

Actually in this case I just would like to get the g-code, because I need to demonstrate to a potential client, if my machine can produce a part that they would need my machine for. I will send You the model files with more details in private e-mail. 2011/6/4 Dave <e...@dc9.tzo.com>: > > Viesturs, I think that you will find that for welding robots a teach > pendant is often used to create the tool path... I suspect that this is the way they are going to do it, I do not really know much about it yet - my task was to design the arm and implement controls in it. The machine was shipped to them this week, I will have to visit them (probably next week, when they will set up welding machine, but it also depends on time of my exams at university) to show them around EMC2. 2011/6/4 Peter Blodow <p.blo...@dreki.de>: > Hello Viesturs, > if it really is a single time situation: Why bother with G code, why not > take that burner in your hand and fry them tubes down once and forever? > > (I know, it's a question of principles.... ;-)) It is one-time show-off to demonstrate the robot's capabilities :) I do not get another job, if that part is not welded by robot.
