Thanks.<br>
<br>
I have some other DIY links, and a friend in Kaikoura paid for some
reasonably well documented build instructions.<br>

I found this NZ source for an Arduino or RPi shield which uses Pololu
stepper drivers.<br>

So really accurate metalwork and a means of moving it are the only
items left to build or buy if you want one.<br>

may open a very large conversation, but you guys seem to be a really
good source of info.<br>
<br>
I'm interested in opinion's on CNC Routers.<br>
I was thinking of something around A4-A3 work area, and the ability to
handle aluminium would be nice but not essential.<br>
My thinking is that more solid items are better sent to a shop.<br>
<br>
The ShapeOko seems like a good start, but the cost inc freight make it
well into ... "what have you brought ... why" conversation.<br>

<br>
I'm fairly sure I can find something else to send my money on, but .....<br>
<br>
<br>
<br>
>From what I see you either have the smaller units using Dremel
style cutters, or larger units with fixed routers, or water cooled
cutter heads.<br>
<br>
The next discussion I see is leadscrew v belts and I note that
Shapeoko3 uses dual belts and steppers for the Y carriage, while others
promote having the work move under the cutter (which does require more
work area)<br>
<br>
<br>
I'm also interested in hearing about DIY versions, or what options we
have in the club to someone to laser/cnc the critical parts.<br>
<br>
<br>
Cheers<br>
