real noob here just a few Q`s if I may

[stk2008]

Hi all I want to design and build me own cnc I have a few ideas for a design that I will share with you once I put them onto to paper.

what I need to know for now is are these motors any good Nema hybrid 8 wire 1.8deg 200 step 5v I think have looked all over for spec sheet on them but with no luck.

allso would this run them in unipolar mode http://pminmo.com/3axis/3axis.htm? and if so do i need to build three as i want a 3 axis machine allso what else would you suggest power supp etc I want to use it to cut ally,wood,plastic etc probably no steel for now.

there is just way to much to think of all the parts,software,hardware etc haha.

thanks in advance.

p.s please forgive my bad spelling and grammer.

Hi,

The specifications you have given for the stepper motor will work well but knowing the holding torque is necessary to know if they are up to the task you plan to put them to.

The driver board you linked to is a 3 axes board so you only need one. You will need to run the steppers at higher voltage than the name plate value (usually up to 20-25 times) to get any useful speed out of them so you will also require the chopper board mentioned on the link

As for a power supply; there is loads of information on how to build an unregulated linear power supply or you could just use PC power supplies as described at the very top of this forum.

It all can be a bit overwhelming to start; just take one thing at a time and you will get there in the end.

Good luck,

John

thanks m8 im still reading posts lokking on sites to get all info i can.
ive installed mach3 just to play with seems nice it says the free unlimited trial is limited to 1000 lines of code is that per program or in total then you have to register?.

ive just got hold of three astrosyn t163-3 no spec sheet so im a bit lost there

8 wire
5v
hybrid
thats all i know any one got specs for these please?.

Hi again,

The limit on Mach 3 is per job; no limit on jobs. I recommend you take a look at Turbocnc from www.dakeng.com/turbo.html it’s a dos program but very easy to use and is free. I’ve used it for a long time now and see no reason to change to Mach 3. Have a look and if you need any info take a look at the forum on the zone.

Can’t help you with the stepper you will have to keep searching. Where did you get them from?
