Greetings everyone. We have been making a lot of progress and everything is on schedule.
First, I apologize if I have not been able to directly reply to all messages. I often don't get alerts on Kickstarter messages, but will try to start replying to them daily. You can reach us directly via email at email@example.com and we'll reply as soon as possible.
We've been concurrently finalizing the case design, electrical design, and website.
We've been working closely with a very talented industrial designer to prepare the case for injection molding. We are ordering the first rapid prototypes this week, and I'll be sure to post pictures as soon as we have them available.
After completing the initial design fitment and accurately modeling all the parts that went into the printer, we began refining the case.
There is an RGB LED light ring the extends around the top circumference of the case. It will be used as a standard status indicator, as well as be controllable directly from mPrints.
Since this rendering was done, some aesthetic changes such as the thumb recesses have been changed.
The last week has been spent on making the case design fully manufacturable, and ready for rapid prototyping. Once we have the prototypes (presumably within the next 10 days), we'll be checking everything for fit and function and make any necessary refinements. I expect at least two rounds of prototype revisions.
The website is nearing a phase where it will be made public to the early developers for testing and feedback. We expect early developer access by Thanksgiving. We will be publishing the preliminary API specifications by the end of November for feedback, and plan to open the website to all users by Christmas.
Electrical and firmware design
The electrical design has experienced very few changes since the last update. The primary MCU is a PIC24F, with a Cortex M0 acting as a print head driver. The largest change is that instead of a single RGB status LED, we have moved to a light ring with a minimum of 4 LEDs. We will be confirming that provides adequate lighting, and have left room in the case for up to 8 individual LEDs.
The largest part of the electrical design remaining is continued firmware enhancements. For example, currently when you first plugin in the mPrinter it creates an ad-hoc network named "MPRINTER", to which you can connect and configure the device. You can leave it in ad-hoc mode, or connect it to an existing network. We plan to also create a setup wizard that works over USB to perform these same functions.
As soon as we have the prototype cases ready, we'll have another update with more photos. Everything is on track for the initial timelines, and we're doing everything we can to beat them.
Again, apologies if anyones messages were ignored or missed - we will be as proactive as possible with backer interaction and feedback moving forward.
