Thread: lots of questions
Hi i'm a total noob and have been trying to get infor on buying a mini milling machine and turning it into cnc.
Im looking at buying a Shirline milling machine, it's size is right for what i need it for. Has anyone used these?
I would like to convert it to cnc with a ready to go or plug and play kits as it were, I believe these are available for this machine, roughly how much would these kits cost? I know these use NEMA #23 motors.
I dont want to write code initially or do i have to, to make cnc parts? Can the software generate the programming code for me?
I have Rhino2 from years ago, i have no problem with making 3D images with graphics software or computers.
Sorry for the questions i have so many.
Google is your friend... or see [ame="http://www.mycncuk.com/forums/showthread.php?t=349"]this thread[/ame]
Basically a CNC Kit for a CNC-ready Sherline Mill is around $250 or about the same in GBP once shipped into UK. You might be better off buying the thing ready-converted as it may be cheaper (unless you are buying a secondhand mill)
There are various software routes, programming is not required (but worth learning). Have a browse through the pages of this forum to get some ideas, there are several threads on the subject.
Is that £800 for just the mechanical parts or does that include the motors, drivers etc??
I used 5A Driver50's for my machine (Router) with 3 x 3.1Nm (5A) 23 size steppers, got the whole electronic kit from Roy (DIYCNC) which also included a 36V PSU and breakout board for just over £300. The only thing you will need is a box to put them all in, I made my own but one or two people use PC cases, wiring them up is a piece of cake. Check out my build log which may give you a few ideas.

What power are the steppers that they are offering?
Your system looks really neat and well set out as i said not to sure how to wire the whole thing up.
Check this out, may be right up your street. Don't know anyone that has got one but Roy would not be selling crap. http://www.diycnc.co.uk/html/system4.html. Very little wiring to do on this one.
Modular design - much less wiring
With Power supply - £250
All you will need is a box to put it in, not a very big one either by the looks of it!
But if you do go for something that needs more wires then don't worry about it, wiring drivers, steppers breakout boards is a lot easier than you think. Wiring by numbers most of the time, took me an hour to get mine up and running on the bench and that was my first attempt!
Thats with stepper motors correct? I might give him a bell.
I might by the sherline mill with mounts and stepper motors and just use it manually for a while then fit a kit like the one you posted.
