TinyG, TinyG V2, Arduinos

Gonna be slow few weeks….

Some researching on alternate control methods for the CNC, avoiding totally the old school parallel port…

Well, today the parts have arrived, I’ll be assembling them soon,

Looks like it’s Very early days for TinyG V2 and the CNC shields along with the Arduino Due..

However, good news it does seem.

TinyG V2 is compatible with the RAMPS-FD and modified RAMPS 3D printer boards…and another board I’ve just discovered  – GAUPS – HERE

Those devices use  the standard Polulu style driver modules – that use the A4988 Stepper Driver from Allegro MicroSystems

My CNC Shield V3 device also uses those devices.

So, fingers crossed, it should be, worst case a simple pin-reconfiguration, probably something I can do in some spare time here

TinyG and G2 – an idea for the future!?

Have been reading up on control methods for the CNC (yep, too much reading, not enough actual do-ing),

Stumbled across something called GRBL, which to summise,is, “an arduino CNC controller”

There’s a shedload of websites regarding GRBL…..so……

I actually own various quantities of each of the following microcontroller boads that i’ve acquired over the years, a few more modern ones include

And, given my recent discovery of GRBL,and a penchant for hoarding un-used demo boards,

I’ve purchased one of these………

an arduino CNC Shield

SKU198457a(3) SKU198457aa

It’s a blatant clone of a couple of other shields out there, at under eight AUD though, it was worth a punt

it uses the standard Polulu style driver modules – that use the A4988 Stepper Driver from Allegro MicroSystems

I picked up five of them also….for just under $14 AUD, three for now, a fourth if I ever figure out 4 axis machining and a fifth as i’ll probably blow something up

a4988 2 A4988 1

so, for a grand sum of $13.81 Plus $7.63 = $21.44 delivered, I have a nice CNC Shield for my Arduino
