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
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
Reading up in-depth more about Arduinos, CNC’s and ‘stuff’, I’ve found a superb product called TinyG
Reading further on the Synthetos website about the TinyG, I discovered a forked branch of the code that is called G2. It’s basically a TinyG Arm port that uses their G-Shield, which at the time of writing is, unfortunately sold out.
I’ve noted that the G Shield uses TI’s DRV8825 stepper drivers
Whilst Googling those parts, I discovered – This website that basically suggests that they’re pin compatible with the A4988 used in those cheap drivers I picked up. Main advantage of the G-Shield device is that it can do 1/32th of a microstep, so much finer resolution for the CNC. Given that i’ve trouble locating the spindle within roughly the 30×20 area of the CNC without smashing into the limits, I think i’ll manage with 1/16th for now
Oh, the picture.
I think i’m going to spend more time buggering about making the thing cut than actually cutting anything…..Still have the software to go yet
Finally, why I haven’t bought a Syntheos product.
I can see that the TinyG V8 board has been out a little while now, there’s headway being made to V9, even some reports of them out for testing. I’m on the wall right now and really happy learning, tinkering. i’ll be jumping and buying a V9 when it’s released :-). V8 is a very well reviewed product so I can’t wait to see what V9 has to offer.
For those of you less into the electronics and general tinkering – highly recommend to get a V8, it’s almost plug and play with these cheap, chinese CNC’s
