Wow- seeing these videos makes me feel like I'm almost there (in real life).

 

Thanx for capturing these! keep up the good work.

Thanks! I still have a few I haven't uploaded yet! I wish I had a better mic though. I'll have to bring one next time.

Kudos on a modern interface

I have been somewhat mystified by how long serial ports have held on in several application areas. I recently proposed a design using USB only to have a manager refuse to even consider it based on a previous bad experience that he had with the interface. USB certainly is not a simple as a serial port, but just the fact that serials are just about completely left behind on PCs should be the writing on the wall.

Does this device do realtime control over that port?

In my fairly limited experience, it seems that up till a few years ago most "usb" mills and similar devices were actually serial with a usb converter in the box. That conversion step has always been a buggy pain in the butt.

newer systems are natively usb and you can just stream g-code to the port. While it may be technically slightly more difficult to make a device that is native USB, the old image of buggy USB just isn't accurate any more.

Great start-up story!!

@Caleb: Really appreciate your efforts in bringing these start-up stories up!! Who knows....may be these guys will make it to the top one day. Pretty cool stuffs they are making...going though their website I see they have made & released the stepper motor driver card for the Arduino board, which enabled them to develop the G-code interpreter firmware and next they integrated the controller and drives in a board to come-up with the controller card itself. May be I don't understand the real advantage of using USB interface for receiving G-code yet, except for gaining higher speed & connectivity to the modern world. I also see the feature on https://www.synthetos.com/project/tinyg/:

"Networkable via RS485 to support motion peripherals and for networking multiple boards for multi-axis systems and for really interesting projects (up to 1000 stepper axes)"

Pretty cool!!

I've seen a few systems that didn't natively support USB. While they would claim usb connectivity it was actually a USB to serial converter in the box. They were a mess to set up and I ultimately ended up just finding a machine that had serial (can be a hunt now days). 

The usb part is not their main selling point, but I feel it is a fairly good feature to remind people of.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
