I have a board on order as shown in the pictures posted by Tony, except that I had ordered it through Ebay before Tony added to this blog. I e-mailed Tony and he confirmed that...

i also can supply 1/2/3/4/5 axis stepper motor driver board and hot stepper motor together,if you intresting in the future pls mail to me swj_119@yahoo.cn Tony S

I never asked for an alternative, just if it the original worked good. You sparked my interest in building my own idle current board. I figured that using what he used would make it compatible. I have these parts on hand and thought I would give it a shot. I am just concerned with the timing and voltage levels to make it work with what he may have used. B0SC0

I am no expert on stepper motors and drivers, but I have done some testing in the past. Power is current X voltage. It makes sense that when you turn up the voltage, the current will decrease at a certain load. The higher voltage should allow you to maintain torque at a higher rpm. Testing the motor at no load would be very different than when it is actually running a machine. Unfortunately, I didn't get that far so I won't be able...

Hi Peter Do you have any information of the chip used in the driver board you are using? On the TB6560 the point to note is that the two output stages are acting as a bridge and clamp opposite ends of the motor coil to alternate sides of the motor supply in rotation to cause the motor to nudge step to step. Since the output semiconductors can not change state instantly in response to the drive there an arrange driver dead gap so that the...

Hello, I have bought this controller from ebay: http://cgi.ebay.com/ws/eBayISAPI.dll...m=260509188593 And I'm not sure if it is working properly. I'm supplying it with 20V DC , and I'm using some 4-wire stepper motor from old printers. When I connect stepper to driver(i'm supplying it with 20V), and to PC's LPT port , suddenly there is high current draw( about 2A), but steppers are not spinning! When I disconnect cable...

Sorry for the misfortune you had. They need to rerate the board to a lower voltage. Maybe you can run 36v but with only a certain size or design. Can a motor design or size affect the amps/volt combo or is it my lack of understanding electric properties. It sounds like they did work fine at lower voltage. Thanks for the good advice. It sounds like maybe my nema17's at 18v aren't as big a joke as I thought. I was looking for a 4axis...

Can you post a link to the motor catalog ?

Thanks heaps Andrew! a
