I recently purchased a CNC kit off of ebay, it should be delivered tomorrow sometime. I was wondering if anyone see's anything missing (not counting the lathe, box to wire them in etc) in this kit to make a 2 axis CNC lathe. I dont see any "driver boards" like Keling has. But just let me know, and sorry if this is the wrong thread.

That kit does include a stepper motor driver board.

The board is commonly referred to as a "Chinese TB6560 driver board".

Some people have success using them, while others have reported problems.

You may want to read through the following thread for more information (it is a fairly long thread, but there is plenty of useful info there):

http://www.cnczone.com/forums/genera...y_chinese.html

While you can not always trust the specifications that they give in some of those auctions, it looks like the motors included in the kit are not a great match for the driver board or the power supply, but you may still be able to get them to work together after a fashion. For example, the motors are apparently rated at 1.0 A per phase, while the description of the board seems to specify that the board is rated for higher current motors (you may be able to select a more appropriate, lower motor current by setting the DIP switches to the lowest current-set value). The motor winding inductance is fairly high, which means that in order to get the optimal speed from those motors you would need to use a much higher voltage than 24 volts (for example, over 130 volts, if I have done the math correctly, but the TB6560 driver board probably shouldn't be used with much more than 30 or 35 volts). The motors have 6 wires, but the driver board only supports 4-wire motors, and so you will have to "tape off" two of the wires in order to connect it (there are two different ways that you could do that).

Hey, thanks for the prompt reply. This cnczone.com forum is quite a community as im quickly learning. I really appreciate it, and i will soon become an active member of this site.

Too late for you, but for others reading this thread, I have had several driver boards with this chip and all but on has failed. If you go with boards with this chip, buy one from a reputable dealer local to you. Generally, they will stand behind their products and help you with any problems you may have. You take your chances importing any of the Chinese products. Always a hit-or-miss.
I get mine from HubbardCNC on Ebay. He tests each board before he ships them, with a video showing that it works, plus a file for Mach2/3 with all the settings for the driver. Still, I got one that was defective and he replaced it. Can't get better service than that.
Just an F.Y.I.

Yah, i am just playing the lottery i guess... i bought this before doing too much research.

I bought 3 before buying from HubbardCNC. Expensive learning curve. Now I prefer to stick to Gecko drivers. More expensive but immensely more reliable with excellent customer service.
