Hello Andy,
Thanks again and I will see if I got more issues to help you out

STL is about all you can get out of OpenSCAD. However, FreeCAD
has a useful feature that lets you paste OpenSCAD text files and
generate solid objects in FreeCAD. At that point all kinds of file
formats can be generated (to transfer to other cad systems).
OpenSCAD is a "programmer's 3d cad

Here is a discussion about inertial mismatch.

The Sizing software that Automation Direct has on their website can be
used to check motor sizing

I guess I should have dug a little more. Thanks Andy.
So would you guys still like me to tackle the man page for the component. Been
reading up on how to construct them, and I am willing to give it a go.

By default, one must click the 'Continue'

Looking at the ha;_manualtoolchange.py file, I see the following:
h = hal.component("hal_manualtoolchange")
h.newpin("number", hal.HAL_S32, hal.HAL_IN)
h.newpin("change", hal.HAL_BIT, hal.HAL_IN)
h.newpin("change_button", hal.HAL_BIT, hal.HAL_IN)

Hi
i am planning to retrofit a machine i will change the servo motors as
current ones are faulty etc
anyways i know the motor ratings on the machine right now as follows
Yaskawa USAFED-30FS20E
Rated 18.6Nm
Continuou Max 22.5Nm
Peak max 54.1Nm
Rated Speed 1500rpm
Max Speed 2000rpm
Torque
Hello all,
I am looking through the docs and cannot find a man page for the
hal_manualtoolchange userspace component, and only see reference to it in the
HAL Examples section of the doc. Also missing is the man page for the parport
rt module. Who do I need to request for these docs, or is it
I believe you can use SketchUp for generating STL files
for 3d printing. Pretty much any 3d cad tool in existence
can do so. Librecad is only 2d, so not much use. On Linux,
you are pretty well limited to Openscad and Freecad.

You'd use a very low fill density, no fill if the pattern can be done that way.
Better slicers now have a variable density fill capability along with variable
layer height.Another benefit of 3D printing PLA for single use casting patterns
is they can be much closer to net shape, which will

But that is 8 hours per part (if using lost-PLA) whereas my
conventional pattern can be re-used.

3D printing needs STL format. Any 3D modeling or CAD software that can output
STL can be made to work as a source for this. One thing though, all the 3D
slicer software assumes you're working in millimeters.
That's due to the original scanning laser and vat of resin 3D printers only
being able

This is a 13kg casting in iron, that would be 2kg of PLA, about £40.
Though i guess you would use a low fill density, so it wouldn't be
quite that much.
But it would be many

I wonder if they've heard about lost PLA casting? One off and short runs
without needing to make expensive, reusable patterns, plus the ability to do
casting shapes impossible with patterns that must be removable from a sand
mold, could be a money maker for the foundry.
