I’m a newbie to Shapeoko…just got it set up and now diving into the software side of things.
I noticed when trying to import DXF’s from Solidworks (2013) into Carbide Create, there was a scaling issue when using metric. It seems Create has a simple mathematical error. With Create settings on metric, a 100mm circle will import in as 2540mm. This tells me that Carbide Create is thinking the DXF is coming in as inches and is converting it to metric (multiplying by 25.4mm per inch . . so in this example it thinks it’s importing a 100inch circle and converts it to metric).
The work around I’ve found for metric:
Before saving your DXF in Solidworks, go to your document settings (Tools–>Options–>Document Properties–>Units) and change your units to IPS. Then save as DXF. Set Carbide Create unit settings to metric. Now import your DXF (which is in inches) to Carbide Create and your 100mm circle will be 100mm, and positioned where you originally had it as well.
