General Mach Discussion / Re: No Motor Movements -- Newbie

Hi all,

I'm writing this post to first thank everyone for their help and second to say I solved the problem so if someone else has my problem can use this info.

My problem was :  Wrong V+ V- (24V) from the power supply to the driver board.  I just inverted the 2 wires and all works fine.

How could I have known ? No wiring instructions and no +/- sign on the pins where you feed the board with current ! Guess it costs too much to put a little sign on the pins 

I had to go through the pain of opening a dispute with Paypal to get the seller's attention, send them photos of my setup, just to find out 2 wires were inverted. 

I must acknowledge though that Mary from LongsMotor was very helpful.

Hi Mike and Tweakie,

Thank you both for the replies.

Mike : I tried your pin set up, did not work.

Tweakie :
 1) ""When you power-up the board (connected to the PC and with Mach3 running) Do your motors lock ??  "" They are hard but turn, not blocked.  So you are right must be pin numbers,  I'll try measuring pins outputs again with a multimeter. I want to find out on which pin do I get values when hit a hot key, then set those in pin numbers.  I don't know if this is the right approach but I'll try it.
2) Port is ok, the leds turn on on the driver board.

I think I have some problems with understanding Active Lows.
When I check (green) active lows for all axes in motor outputs I get bright leds on the board. Then they turn off if I uncheck them (red X) and hit the hot keys.

Could you please tell me how to set active lows on everything, including Estop when I have no machine connected.

Thank you again for your patience and help.  May G-d bless you.

Hi Tweakie,

Thank you for your reply to my post.

Wish I knew this board was a crap before buying it .... my bad ! Anytime I try to save on something I spend twice .
I still have some time to maybe send it back but before that I must make sure it is not my faulty setup.

I have done as your instructions and still no noise, no movement !

I attach my xml file and will really appreciate it if you or someone else can take a look at it.

Thanks again.

General Mach Discussion / No Motor Movements -- Newbie

Hi all,
As my nickname says I'm going nuts.  Have read more than 70 posts in different forums but still stuck, so pls help if you can.

I have downloaded and set up mach3 as described in the wonderful video by ArtSoft.
I have hooked my motors and control panel  (oh no, another of those cheap Cinese junk !?! I'm on a tight budget !)
TB6560 (green) 3.5 A, 16 Mic steps, 3 Nema 23 270 OZ 3 A, and the supplied power supply.

Pls see : http://www.ebay.it/itm/301100034359?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

To test the motors I have attached Blue to B- ,  Red to B+ , Green to A- , Black to A+ and setup all pins as manufacturer's specs.
I have tested the LTP port with a multimeter and even though I get an inverse value for a couple of pins, I still get 4.5 V and 0 for most pins when pushing the hot keys on the keyboard.

I have no CNC machine attached, just trying to test run the motors.

But, I CAN NOT GET ANY NOISE OR MOVEMENT FROM THE MOTORS !

Appreciate your help.  Thank you.
