Re: Commercial Style Cartesian Bot - 17 years ago
OK, got it... Al on Al, BAD. Guideing Rods, GOOD. I'll see what else I can come up with for V3. Thanks for all your help.by Pheobot - Mechanics

Re: Commercial Style Cartesian Bot - 17 years ago
ok... I think I understand. But if I slightly Mix V2.0 and 2.1, this will mean I only have to add another x-axis, and not another z. I think I'll add a rail system for the other x-axis. using 4 skate bearings and a "T" shaped piece of aluminium.by Pheobot - Mechanics
Re: Commercial Style Cartesian Bot - 17 years ago
I don't see the need for another z-axis, or x-axis... Could you please explain... thanksby Pheobot - Mechanics
Re: Commercial Style Cartesian Bot - 17 years ago
Version 2.1 Thanks sid, you were right about the z-axis. how about this one then? Anthonyby Pheobot - Mechanics
Re: Commercial Style Cartesian Bot - 17 years ago
Thanks for the suggestion Regarding the z axis, but I had thought of the y-axis, Iby Pheobot - Mechanics

Please take a look at my design, It's taken from commercially available linear positioning systems, and is fully modular and relatively cheap. Using 3 bipolar stepper motors in aby Pheobot - Mechanics
Re: Glue-Gun as Thermoplastic Extruder - 17 years ago
Thanks for all your Help. I think I'll do some tinkering and see what I can come up with. Anthonyby Pheobot - General
Re: Glue-Gun as Thermoplastic Extruder - 17 years ago
I can see how the glue gun's mechanics are all wrong for automatic use, but do you think that the heating mechanism could be modified to take a smaller diameterby Pheobot - General
Re: Glue-Gun as Thermoplastic Extruder - 17 years ago
Thanks for the reply. It's just that getting a glue gun is alot cheaper then makeing a Mk II. but if the glue gun can't provide a good result then I'll have to try something new.by Pheobot - General

why not use a modified Dremel-like tool to etch a blank circuit board? this would be a lot simpler then lasers and tanks full of molten solder.by Pheobot - Mechanics

Hi, I'm in cairns. I'm a Drafter, not mechanical, but I'm designing something very similar to the Reprap system, based on items easily available in Australia. It canby Pheobot - Australia, Brisbane RepRap User Group
