General Mach Discussion / Re: Newbie with TB6560 1st time testing problems

Hi Gary,

The stepper motors should lock when power is applied with Mach3 running and the CNC connected to the PC.

What I have here for the step / direction (blue board) Mach3 configuration is as follows;

Xaxis  Step16  Dir1
Yaxis  Step14  Dir7
Zaxis  Step3   Dir6
Aaxis  Step9  Dir8

Enable1  Pin4
Enable2  Pin17
Enable3  Pin5
Enable4  Pin5

Output#1 Pin2

Does this match up with the instruction you have been supplied ??

(As Jim has pointed out there are so many variants of pin connections with these boards and the suppliers instructions are often incorrect so they can be difficult to get going).

Hi Gary,

Sorry, I did not make it clear in my earlier posts – when I referred to “motors locking” I should have said “stepper motors locking” - the axes driving motors (my bad).

Still it is good news that the M3 command operates the spindle motor.

One more question – what colour is your TB6560 controller board ??

Hi Gary,

When the CNC machine is disconnected from power the motors can easily be rotated by hand. When the CNC machine is powered up the motors should lock and cannot easily be rotated by hand.

After a fresh start and without Mach3 running - using a multimeter measure between pin25 and each of the other pins, in turn, on your PC’s parallel port until you find one that has a voltage present. Ideally the voltage you should find will be approx 5 Volts. If  you are unable to find a voltage then start Mach3 and try again.

Hi Gary,

Many, before you, have had unresolved problems with the TB66560 boards and this is perhaps not the best board for you to be starting out with, however...

Perhaps you could try the supplied .xml file and see if this works (you can always go back to your own manually entered settings).

Do the motors lock when power is applied ??

Does your PC have the 5 Volt TTL standard for it's LPT parallel port or is it the 3.3 Volt TTL standard ??

I am really pleased that you have got it working OK.

This is, I think, another classic example of Mr Hood's brilliance of knowledge and determination to help others.

Ooops, my bad - totally forgot you are using the ESS.

Hi Boris,

I doubt that there is a pull-up on the computer’s LPT parallel port (although you could possibly have a bad Pin 10). There are, however, often a pull-up’s on the inputs to the breakout board / controller board.

I suggest that you wire your e-stop so that it takes pin 10 to ground with a pull-up to +5 if necessary then configure e-stop as Active Low.

That's strange because I use Mach3 R3.043.066 and the M10P1 / M11P1 work just fine here with my laser so perhaps have your configurations set up incorrectly.

The M10P1/M11P1 commands produce a signal on Output#1 which in turn should be configured to the LPT port output pin of your choice. The chosen output pin number should not be enabled for any other function (ie. spindle) within your configuration.

Sorry, but I don't think the .ngc file extension is a supported Mach3 format.
