This version of the app you can download from this site and from the app store is the Free Version. This version is fully functional, but has a couple of limitations as follows:
- The maximum output size is 40mm by 30mm (or 1.6” by 1.2”).
- The minimum laser focus point supported by the free version is 0.1mm (or about 4mil).
- Non-commercial use only.
If an attempt to create a G-code for a larger output is made, the app will simply crop the output to that size (note: crop, not resize).
Unlocking the full version is possible from within the free version by clicking on the Details button and then the Purchase button.
- In macOS this is done using the standard App Store purchase.
- In Windows this is done via a PayPal payment (your browser will open PayPal’s secure website; once you have completed the purchase, simply click Restore Purchase button within the app).
In all platforms, the full version costs just $14.99 as a one-time payment.
