[Update: Current board changed from NuttX to FreeRTOS. Also we are using SPIFI instead of Parralel Flash]
Smoothieboard is an Open-Source CNC controller for digital fabrication machines. V2 is the new version we have been working for years ( both hardware and software getting massively upgraded ) and we are getting close to doing a Kickstarter ( the first version had a very successfull crowdfunding campain ). This video gives an update on project progress and well as a tour of the main features for the core v2 board.'

I everyone, I wanted to give you an update on the status of the Smoothie v2 project.
You can read the specs at the link in the description ( [ Ссылка ]# ) but I wanted to give you a tour of the current v2 alpha design.
On the firmware front, Jim Morris has ported a big chunk of the code to the new architecture. It's currently capable of laser cutting and CNC milling, 3D printing is coming soon. A lot of the more periphiral code still needs to be ported but it's already usable.
On the boards side of things, we've had protos of v2-mini ( the low-cost simpler variant ) made and tested, and had protos of the v2-pro ( the expensive one with the FPGA ) made too but the design of that one has changed so much since that we'll have to do another round of protos for it.
The board design Mark has been working on recently is v2, the "middle" board which will succeed the current v1.
Here's a tour of it's main features and novelties :
MCU:
* Faster ( 204Mhz vs 120Mhz ), more features, much more RAM ( 264kB versus 64kB currently ).
* No internal flash
* FPU
* M0 Co-processor ( experiment )
* NuttX RTOS
* Working on awesome bootloader
Flash:
* 8MBytes
* Parrall interface
* Already 1MB
Logic power
* 5V/3A regulator for all boards
* Protected 5V input
MicroSD:
* SDIO, much faster, expect megabyte-second-range transfers.
USB:
* Now with A and B, so you could for example plug in a USB Thumb Drive
* Working on USB/MTP, explain
Ethernet:
* Excpect it to do much more
* No crashing
* More speed
Raspi:
* Raspi interface
Stepper drivers:
* 4 TMC2660
* 2.8A max
* Very nice microstepping
* Kits for extra drivers
* TVS diodes to catch back-EMF
Stepper power input:
* XT30, this handles 30A which is much higher than the 12.5A v1 could do.
Mosfet power input:
Control things like heaters and fans
* XT30 too, you can provide different voltage to the steppers and mosfets
* With main shut-off for heater safety
* Simpler than v1
* Both have reverse polarity protection
Mosfet:
* One big mosfet with XT30 output
* Two smaller mosfets for hotends/etc
* One fan output
* All have back-EMF diodes
Analog:
* 3 thermistor inputs
* With over/under voltage protection and current limiting
* One analog output ( DOC )
* Board can do power sense
Servo/SSR:
* Two outputs
Endstops:
* 7 inputs ( now with probe input )
* Probe input is 36V tolerant
Gadgeteer :
* Many possibilities
* Plug in extension boards
* Give examples
General:
* 8 layers board, very good heatsinking
* Connector distribution : on the borders as much as possible
* All "outside facing" on the sam side
Debug:
* Proper JTAG port this time
Dimensions:
* 120x120mm
Holes :
* 100x100mm spacing
LEDs:
* Now with a LED for the FET power input
