    Lightbulb Imperial to Metric in Madcam?? - Laguna iQ Mill

    Hello-

    I am helping my dad set up his mill to produce guitars. I have previously used a Patriot Mill in school and would use Madcam to post process my g-code in Imperial Measurements. I just learned the Laguna machine my dad has runs Metric, so my code is not running correctly.

    I converted the rhino model to mm and converted the tool and toolpath numbers in madcam to mm and the program ran 90% correcly, but it slightly out of scale in the Y-direction. It is as if the machine thinks my stock material was larger than it is but when I check its coordinates/measurements directly in the code, it is correct (I tried several post-processors too and file pathways). I'm not sure if madcam actually supports mm measurements when I load the tool or set up the toolpath - is there a way to switch madcam to mm? If my rhino rhino is in mm, how do I input the measurements or units into madcam so that it recognizes mm?

    I also tried to edit the G20/G21 directly in the code (prior to when I converted my model to mm, still in imperial at this point), but received an error that X/Y was out of bounds when I tried to run it on the Laguna. I also reset the origina at this point. Do I also need to change the Feed speeds?

    Are there any work arounds for this? I am a student so I only have free access to Madcam- I don't want to have to use a different software.

    Let me know! Thank you!

    Changing the G20/G21 in the code would have told the machine that it would be running on a job 25.4 times as big as the intended part-hence the warning.If you have an imperial Rhino model of the part you can scale it in 3D by opening a new file with metric units as default and importing the part.You will be asked if you would like Rhino to convert it by the appropriate scale.Do so and save the new file in a format that Madcam can read and then generate the toolpaths from a correct model.I must admit I'm a bit surprised that your school experience didn't include some work in metric as using only Imperial seriously restricts the number of places in the world that you can do business with.Much more useful to be bilingual with dimensions.
