Thanks for the info both of you. @Traumflug: I trust you got my PM responses (second as well as first).

Thanks for the clarification gents. The documentation looks good Gary!

How many stepper motors for a Prusa with Wade-like extruder? - 13 years ago

Hi. I'm a bit confused about how many stepper motors I need to build a Prusa. I am planning to use Greg's hinged accessible extruder (a variation on Wade's extruder). I know the standard recommendation is to use the NEMA 17 motors - and I can get these via mendel-parts.com, thingfarm.org, or any other number of sources. What I don't know is whether I need 4 or 5. Obviously one is needed for ea

Re: Hot end for Greg's hinged accessible extruder - 13 years ago

@jcabrer: I'll have a closer look at the hole for the hot end when my ordered parts arrive. If they are compatible with your hot end I will definitely look into it.

Ok - thanks for picking up on my sloppy terminology. Anyway, I'll probably try this once/if I get a reprap up and running. david

PCB house recommendations - 13 years ago

Apologies if this topic has been raised already - but a cursory search didn't yield much info. I like the Generation 7 Electronics and am toying with the idea of going with it rather than e.g. Sanguinololu or RAMPS. Seeing as it consists of only through-hole components, I think I could manage the assembly myself. So, if I decide to order the PCB rather than etch one, does anyone have recommenda

Re: Open-source brep-capable CAD tool w openscad-like language? - 13 years ago

Maybe you're right Markus. I don't really know FreeCAD (or Python) well enough to tell whether or not that's viable to be honest. I will say though ... Scripting features aside, the GUI is more sophisticated than I had previously thought; and the more I experiment with and get to know FreeCAD, the more I like it. It's drafting module is very nice, and includes at least preliminary dimensioning ab

Re: Hot end for Greg's hinged accessible extruder - 13 years ago

Hi there. Thanks for the response. I think I'll probably be going with the makergear extruder - based on the positive reports you've referred to. I'll try to post updates here.

thermoplastics and wireless transmission - 13 years ago

Say I wanted to use a 36 kHz infra-red receiver for a project, and wanted to enclose the receiver in a mini-channel to limit its field of view. Could PLA or ABS be used to accomplish this? i.e. could it block wireless signals around that frequency? Would it depend on the colour?

Hot end for Greg's hinged accessible extruder - 13 years ago

Someone has offered to print Greg Frost's version of Wade's extruder ( ) at a reasonable price for me. Before doing so, however, they need to know what hot end I want to use with it. And, frankly, I don't know. Looking at the openscad file, there seems to be an option between six different hot ends - defined by the following variables: malcolm_hotend_mount=1; groovemount=2; peek_reprapsou

Open-source brep-capable CAD tool w openscad-like language? - 13 years ago

I would love to see an open-source CAD program with these features: BREP support (rather than just CSG) dimension / annotation capability (to facilitate documentation as well as just sending straight to a CNC machine/reprap) openscad-like programming/scripting language I am very fond of Openscad's language - but (to the best of my knowledge) it only does CSG. I am also fond of the opencascade-b
