Machine Sim Wrong Scale at Simulation

[JAGUILAR24]

Hey everyone,

I just created a  machine sim file for our Haas VF4SS w/ a HRT310SP rotary and when I exported each STL as IN units, when I create the machine all components reflect what I exported. I set all the axis limits as the actual machine. When I go to simulate a part, the tool and part are a different scale than the machine. Even the travels for each axis are downscaled. All files are in the same units(Inch) , and my configuration for STL exporting is also set to Inch. Am I doing something wrong? Any and all advice is greatly appreciated.  Here is a pic of what I'm seeing at simulation.

You have a scale on something wrong. Without seeing everything would be hard to narrow down your specific issue.

When I work with Machsim I always work with mm models...

They convert when using it automagically..so it's not an issue

Thanks for your response Ron. I exported the STL models in MM, and that seemed to work. Why is that if my main simulation file is in Inches? 

I'll try another machine to see if that's a fix for it.

I tried this just moments ago and it worked! Thanks!

It's the native format of Machsim....it lives in MM...so when using inch, it converts

The system likes Metric, it is the default in the file header. If you build the machine in inch, after you save it, open the XML file in an editor and make sure that the header says inch or it will scale it when you go to use  it.

Example:
<?xml version="1.0" encoding="UTF-8" ?>
<machine_definition>
    <machine_data name="Fanuc_Robodrill" version="1.8" units="metric" controller="">

Change it to the following:
<?xml version="1.0" encoding="UTF-8" ?>
<machine_definition>
    <machine_data name="Fanuc_Robodrill" version="1.8" units="inch" controller="">

I appreciate the feedback Craig! I will definitely try that on my next machine build.
