CAM simulation for the Path Workbench

[shaise]

Hi JoshM

Sorry for the late reply,
Yes, G/s is gcodes per second
and the accuracy percentage is the resolution of the simulation. The simulation is done by deviding the stock object to voxels. Say a stock is a square material, a 1% accuracy means a simulation of 100 x 100 voxels. a 0.1% means an 1000 x 1000 simulation.

Hi Shaise,
I have read here that you are busy at the moment, so there is probably no chance to get the error fixed tha no material is taken away in the simulation. But would it be possible to revert the the last change you made, so that we can create an animated gif for the documentation?

If you don't have the time to fix it before 0.17 is out we should revert it anyway.

Hi chrisb,

The changes are not mine, so its hard for me to know what to revert. I'll try to look at it this evening.
Are you saying that now the simulation does not work at all?
Can you post a sample fcstd with the simulation you wish to gif?

The simulation window opens, I can adjust the parameters, when I start the simulation the tool moves as expected. However, it does not take off any material.

Can you post a sample fcstd with the simulation you wish to gif?

Of course, it is the example from my walk-through in the documentation. Give me a minute, I wanted to upload it there anyway. If I don't succeed, I'll upload it here.

Here I am again, it is only possible to upload image files.

Chris, let me know of changes you wish

Chris, let me know of changes you wish

Thank you very much, I integrated it in the walk-through as well as in the Path Simulator documentation.

Did you create the animation with an old version or is there a fix?

And a last question: When I end the simulation and hit the Ok button the artificially created simulation stock object stays in the tree. If the simulation is not finished it even obstructs the object and the paths. Is this intenden behaviour? It seems to me that only the cancel button makes sense, so I would remove the "Ok" and rename "Cancel" to "Close".

Hi @chrisb

I'm trying to get in touch with the guy who added the latest changes. Hopefully he will fix it, if not, I will get into it myself

Hi @bill,

Did you use the latest build to get the simulation right? if so did you touch the model file?

Hi Chrisb,

Thanks for the documentation!
Yes, the OK/Cancel system is intended. If you want to save the results of the simulation for later reference, press OK, if not, Cancel. Unfortunately, I can not keep the dual color object as in the simulation itself, as freecad supports only a single color for mesh objects. (for the simulation I cheat - I hold 2 separate mesh objects for the 2 colors. but these are non manifold (each have holes where the other dont) so I cant keep them.

Since your there, shais, off-the-cuff, would it be difficult to tilt the view window slightly by a few degrees; it provides a much improved presentation at least in the axonometric view; from what I am viewing!
