could some one help me .
I have 3 step motors mod # c6838-9212k-c5
2-phase 1.8 DRG step
DC2.57v 2.8A
VEXTA
would these work for home built CNC
mill if so what volts /amps/and so on should I run them at.
Thanks much

Those are nice motors. 4 wires or 6? What driver board do you plan to use?
We can answer a little better once we know those details.
Eric
I wish it wouldn't crash.
4 wires I dont no what driver board to use
thanks muzleldr
I would use this board http://www.xylotex.com/#3axis
You would need to keep the current under 2.5 amps, but the is a current pot to do just that on the board. I would use a 24 volt or more powersupply.
I am not sure of the torque of those motors but I am sure they are 150 oz+
They will be perfect for a home made router. How large a machine are you planning?
Eric
I wish it wouldn't crash.
I was thinking of about 2'x4' mill.
mabe geco driver board because of
$ geco build your self kit .
all help and info welcom!
thank you

With the gecko's you need 3, one for each motor. They handle the current no problem at 7 amps each.
Eric
I wish it wouldn't crash.
is that 7 amps good/bad
I thought I saw a geco drive for 3or4 axis.
lI am still in the planing stage but I have the stepers and did't know if thay would work.

If you are refering to these drives, www.geckdrive.com then no, you need one for each motor. yes 7 amps is good.I thought I saw a geco drive for 3or4 axis.
If you are building your first machine, I would stick to the cheaper xylotex board. It should be fine for those motors. You may want to doublecheck with them to be sure.
Also, start a little smaller for your first machine...say 2' x 2' or even less (I would recommend no larger than 2' x 1'). There are plenty of challenges in building a cnc router without the added complexity of a larger machine. Trust me...I know...
