Not much coming in to the MickMake studios this week so I delve in to a 3D printer I received from BangGood a couple of weeks back.

SAM4S Xplained Pro
I bought a couple of these for a project I’m working on that relies heavily on ultra low power consumption. So, two boards to play with.
The SAM4S has:
- 120MHz Cortex-M4.
- 2M program flash.
- 160KB RAM.
- DSP / FPU onboard.
- SD/eMMC – can execute code from SD & eMMC support.
- 3.3v logic.
- SPI, I2C, USB2.0 host and device mode.
- 22 DMA channels.
- 15 ADC channels at up to 1Msps.
- RTC.
- 79 GPIOs with hardware debouncing filters.
- Peripheral Pin Select Crossbar.
- Sleep mode down to 1uA.
SAMG53 Xplained Pro
and then there’s the SAMG53.
- 48MHz Cortex-M4.
- 512KB program flash.
- 96KB RAM.
- Similar to the ATSAM4S except without SD/eMMC.
- Fewer DMA channels.
- and only 38 GPIOs.
- Sleep mode down to 1uA.
Stay tuned for some MickMake products hitting the shelves soon!
Anet® A6 3D Printer
Then there was the Anet A6 printer that had been sitting around for some time. So, decided to put it together.
Putting it all together was pretty straight-forward. There are two videos that will last an hour. I suggest making it as you watch it.
Alas, no grub screws in one of the steppers. 
The screen was a little dodgy, but not a huge drama.
And I was little worried about the mains setup on the power supply.
But, I was impressed by the level of documentation this printer had.
