Have you satisfied yourself that you have 5V now on your PP? If not and your drivers NEED 5V then this may explain the motor vibration.

well I guess from your reply to me you did take a tad offence at what I said which is a shame.

Just go back through your thread and ask yourself who's been with you on this consistently. Who took the time to google your kit description in post#3 to get the datasheet of your driver. who cleared up the issue of bi-polar vs uni-polar motor confusion. Who suggested your bold DRO concerns were not the issue. Who suggested the route of repair to save you money and who gave you a start on finding your chip. Take all MY posts out of your thread and see what you'd have left.

If I've wound you up simply by suggesting you post links to your kit and then do a little googling so be it.

have you tried flipping the active state of your E-Stop pin?

Your post looked like one of the many "can you do it for me" type posts. My apologies if that was not the case.

OK - Mach can be configured as a modbus RTU master. Please see the videos under support at the top of the forum.
You already know about virtual com ports so you're ok there.
Next your app must be configured as a modbus slave to send command tokens to Mach3. There are many open source implementations and source codes available for modbus slaves.
Next you need to write either Mach3 macros or Brains to interpret those command tokens and carry out the control of Mach. Again see the videos and links under support for macros and/or brains.

Hope this helps you get started.

<sigh>

from

i have experience in software for serial communication and microcontrollers programming, i was wondering if there is some possibility to control mach3 from outside software through serial port?

to

i am very begginign and i don't know nothing... can you guide me just to create a very simple program in modbus...any way is ok for me... just i want to achieve the result..

in just two posts.

Free lunches are two doors down.

jaybone - no offence but maybe YOU need to do a little work on this. I did this process and within 3 minutes I'd found a full BOM and suppliers and prices.

WADR we're here to help - not to do it all for you.

Hi xhuxhi - welcome.

Many ways to do it - what you're wanting to do is really just a soft pendant. Modbus is a way (as you say via a virtual com port) - but there are other ways too. Up to you really.

This was a kit yes? - why not just replace the chip?

Forget about COM ports. COM ports are SERIAL ports. Mach drives axes through LPT ports i.e. PARALLEL ports. Also forget about what numbers windoze calls your LPT ports - it's irrelevant to Mach.

Look in device manager at the resources for your parallel (LPT) port(s). If you have more than one, decide which one you want to use and look at the start of the I/O address range and make a note of that number. Let's assume it's 0378 for example.

Now go to ports and pins. enable port #1 and enter 378 as the port address. Disable port #2.

Now go to motor-outputs tab and set step port and dir port for the axes you're using to 1.

and please fix your keyboard shift-key. Thankyou.

I expect the issue here (which is why I wanted to confirm that this system has worked in the past) is just confusion by the OP over what constitutes a Bi-Polar motor (WRT steppers). Just for clarity (for the OP):

A Bi-Polar motor has 4 leads.
A Uni-Polar motor has 5 leads.
A 6 lead motor is a motor that is primarily designed to be wired Uni-Polar but that can be wired Bi-Polar.
Finally an 8 wire motor can be wired as either Uni-Polar or Bi-Polar.

I suspect the motors in question here are 8 wire.

From the description of the problem I would guess that the second phase of one driver on the board has gone awol.

IMHO the "bold" issue is just a screen artifact and therefore a red herring.
