Toolkit for vismach model was created by chris@cnc
I try to create my own vismach model, but it is very hard to set up and place parts in the right order and size. Exist there any tool to create a model, or can i only write the python file by hand.

I don't know of any other way of creating a vismach model other than to write the code by hand. I have recently found a small tutorial:

Some tips here as well:

Note that you can import stl files instead of creating the shapes in the vismach code itself. The tutorial above mentions that as well.

Thank you, for . For *.stl i found the vmcgui example. But to build parts together in python is very hard. I'm also looking for existing models they similar to my design and found something. I have a 3 axis mill with optional A-axis. I try to modify this on page 31 without b and c but basic file won't start. What is wrong.
ich@debian:~/vismach$ halrun

Unlike other languages Python is very particular about indentation, meaning you can't just start every line at the beginning.
Maybe this helps to start out:

you also might want to start out with the file that is in the linuxcnc source code:

I thought it was a grammar problem. That hits me in every language

I believe that exporting as either STL or OBJ will work, and Fusion 360 (for example) supports both.
The machine in VMC_toolchange was modelled in CAD.
Hmm, I have a full 3D model of my lathe....

You can model the machine as an assembly in CAD (it's easier if you _create_ everything in the right place) and then export.I try to create my own vismach model, but it is very hard to set up and place parts in the right order and size.

A vismach lathe would be a great addition to the samples....

I have been trying today and found it very trying!
I opened a single STL model of all parts provided to me in F360, made a rigid group and then set the part origin to the spindle tip. Then I exported all the parts as a mesh in Ascii STL. THey should have known where they lived I then went to put the vismach together from the spindle tip which went well for the first 2 bits, then the orientation changed so the spindle body ended up over the tool and the z axis slide went somewhere else!
For what its worth there is a Linux STL viewer I found called Paraview that has been handy. It will export binary STLs to ascii for vismach.
