General Mach Discussion / Re: PWM signal not showing correctly

« on: August 29, 2012, 06:13:49 AM »

Hi Andre,

You are possibly looking in the wrong place with your oscilloscope. The PWM signal is on the Spindle Step Pin (as set up in Ports and Pins / Motor Outputs).

FAQs / Re: i need help!

« on: August 28, 2012, 03:47:58 AM »

Hi Stephane,

Perhaps some more details of your machine and it’s set-up may be helpful in identifying the problem.

If you have an occasional ‘tick’ when driving your stepper motors from one end to the other end of an axis travel then this could indicate ‘lost steps’. If any of your stepper motors make this occasional ‘tick’ when stationary then I would suspect the problem is electrical noise.

Is your limit switches and e-stop wiring made with shielded cable ??

Also….If you return to the main forum page then carry out a search for ‘lost steps’ you will find many suggestions, some of which may be helpful to resolving your problem.

General Mach Discussion / Re: need help and advice on conversion project-motors/drives/mach3 tuning

« on: August 28, 2012, 02:36:49 AM »

Hi Homer,

Your stepper motors should be running warm to the touch but not so hot that you cant hold your hand on them. If they are running too hot then reduce the current setting to your motors (voltage is OK).

As for the stalling (squealing) - you need to reduce your Velocity and Acceleration setting in the Motor Tuning section and then 'Save Axis Settings' - Try using a velocity 30% less than you currently have set.

General Mach Discussion / Re: Touch Off Macro Half Works

« on: August 28, 2012, 02:07:38 AM »

Hi Greg,

I understand your dilemma but the problem is not so much with your macro (which works fine here although, as Gerry has pointed out can be improved upon) as it is with the way in which the Mach3 software running on your PC handles it.

Because I and many others use the Auto Tool Zero function, without issue and on a daily basis I can only conclude that your problem will somehow be with your setup. If possible could you perhaps try the temporary use of another PC and see if this makes any difference ??

General Mach Discussion / Re: Text centering

« on: August 27, 2012, 03:35:25 AM »

There are many options but the method I prefer is to set the datum (X, Y Zero) at the centre of the created text then locate the centre of the work and zero the machine at this point. As you have discovered, the engrave wizard is not so good for this but there is a free engraving software "F-Engrave"  http://home.comcast.net/~sskroch/Fengrave/fengrave.html which is almost, if not perfect for this task.
