I see that you plan to GPL the firmware. This is a great first step towards a truly Maker friendly device! However, the reliance on the cloud service is still a sticking point for many people. There are many situations in which a cloud service is impractical, and many are rightfully concerned about the future, whether that’s Glowforge ceasing operations or being acquired, or simply deciding to monetize what was previously available for free.
In other comments you have stated that the Glowforge will have an entire Linux environment onboard, which is great! However, without the ability to control the machine directly without voiding the warranty, we are still dependent on the cloud service with all the associated downsides. Will Glowforge commit to offering an open, published, supported API directly from the device, for those that wish to develop their own software?
