I started out with the Chinese version from ebay that came with the power supply and steppers, yet all I could ever get to work was the Z axis, and one of the other axis' would lock up from the enable. I was able to switch around the motors and all the motors worked when hooked to the Z axis.

Wrote it off as a bad driver board and sent back to China in for repair, and then bought the TB6560 from cncgeeker.com to replace it for a while. I just got it wired up tonight and am having the exact same problem, but this time only the Y axis is working, and still only one other axis is locking up from enable. Curious, I checked the pinouts and on my first board Z axis used pins 4/5 for Z step/direction, and on my current board it uses pins 4/5 for Y step/direction. So basically the only inputs going across are 4/5 and two of the enables.

The parallel cable has also been tested and all pins are good.

I would be dead set as it being a computer problem, but I tried shorting the manual pins out, but again only Y will move. I have tried two separate computers, one a Dell 3300 and one a Dell 8300, both on EMC2. Is there possibly a setting in the computers parallel port that needs to be adjusted?

Thanks in advance!

Scheer,

1: I would shy away from using a laptop until you get the driver board operating correctly.

2: If you are having the same problems with the 8300 either the step & direction pins are not configured properly in EMC2 our your DB25 cable is not wired correctly i.e. straight through.

My bad, The computer is a 2400 desktop, not a 3300. All the pins are wired according to the manual, but the DB25 cable is strait through (If I was to plug the ends together, pin 1 of one end would touch pin 1 of the other end, for all pins). I assume you are meaning that it isn't supposed to be strait through? And if not, where could I find the correct pinout?

Scheer,

The cable should be wired straight through.

It sounds like the manual may not be correct.

Can you post the manual?

On the 7th page.

I just checked voltages, and on my enables I get 3.3 volts on one, .23 volts on another, and no voltage on the last. However, when I tell it to move I get 5.5 volts on the step pin, and still 3.3 volts on the enable pin.

I completely forgot to mention that the led's do light up for each axis when I try to move it....

[Scheer]

I went and checked all my voltages on the DB25 while the computer thought it was moving the axis.

X Step- .07
X Dir- 3.3
X Enable- .23

Y Step- .12 ( Saw 5.5 the first time, but could never repeat it)
Y Dir- 3.3
Y Enable- 3.3

Z Step- .12
Z Dir- 3.3
Z Enable- Nothing

I am really confused now, because Y and Z will both enable and lock up where there is resistance, yet I can't get a voltage on the Z enable pin. I guess it might have to do with the controller not being hooked up... X is the axis that does absolutely nothing, no sound, no movement, not locking up.

Let me know if there is any more info I can provide that might help.

Scheer,

The enable pins must have 5 volts d.c., you could try using a cheap 5 volt d.c. power supply from a cell phone to provide +5 volts to pins 8,9 and 14.

Configure the step and direction pins for active low.

scheer i am haveing a problem allso so if you figer it out let me no by the way the one you got from china
i got that now my y axle is acting up im going to right a post for help on it

but if you need 3 Axis TB6560 setup for china i got 3 defrent setup's lol
i guess they make defrent's modals or something
