Re: Computer Aided Manufacturing Tutorial ( Path Workbench)

Thank You for your time to make a great tutorial! I have a question about the path operations. In the tutorial you started with a piece of stock that was wider than the finished product and used a contour operation to bring it to size. I am making some parts from a standard width of flat aluminum. I...

Re: Trouble post processing job in V0.19

Many thanks for that heads up. That is what I get for trying to do calculations in my head. I changed the stepdown to 0.127 and the post went off with out a hitch. I am going to go back to my previous drawing and see how this works there. Again many thanks.

Re: Cannot view gcode after post processing

Sorry Chris You are 100% correct. I went back through my calculations and 0.001 mm is mighty small. I changed the stepdown to 0.127 and the post went off without a hitch. I need to go back and check my previous drawing and test it, but I think this will solve my problems. Many thanks for getting me ...

Re: Cannot view gcode after post processing

Yes. This is a very small light weight router of Chinese origin. Before I start increasing speeds and feeds I would like to observe it under these conditions. The two 'wings' on the base part are there to avoid my clamps. Is there another operation I should be using? I really only want to radius the...

Cannot view gcode after post processing

After submitting a job for post processing FC used to ask for file name confirmation. It no longer does this. When it finishes with post processing it displays the gcode in a small window in the center of the screen. If I interact with this window in any way FC locks up. I have checked the directory...

Trouble post processing job in V0.19

I am having difficulties with V0.19 in post processing a simple part. FC either fails to complete the post process action or locks up when displaying the processed gcode file. I changed computers yesterday as my laptop seemed to be struggling trying to run FC. The change in machines has sped things ...

Re: OpenCAMlib for Windows

Hi everyone. I am new to this part of the forum. It sounds as if I will find my answer here. I am getting an error in the report view that says "opencamlib is not working" I read through most of the posts and it seems that you have been successful in cimpiling a version for windows. What I am not un...

Re: More questions about path workbench

<t>I had a brilliantly written reply last night and lost it somehow. So I will cut right to the chase.Until I have a lot more successful hours under my belt I don't even feel remotely qualified to begin telling people how to use the program. Moving on.<br/> <br/> I have been using V0.19 for a couple...

FreeCad locks up when selecting face

In the attached drawing when I try and select the top face of the part FreeCad becomes unresponsive. I tried the pocket operation with the four internal faces of the pocket, but this produced no g code. I have also experienced issues with the tool controller losing the parameters of the tool. Where ...

Some ideas for the path workbench

I think what would be helpful to all is a description of each operation. It should include what type of surfaces can be added as base geometry. What sort of tool it expects. The parameters for the tools that will perform a successful operation. For instance I have a pocket operation that goes all th...
