General Mach Discussion / Re: laser setings

« on: November 21, 2012, 01:45:11 AM »

Using a relay is not practical because of the associated delay.

If you work your way through this thread (may take some time) you will see most of the available options for laser control including using the M10P1 / M11P1 commands for vector work as well as using the Mach3 Impact / Laser plugin for raster work http://www.machsupport.com/forum/index.php/topic,12444.0.html

Hope this helps.

Thanks tweakie, that helps. Do you guys think adding a wireless network card could cause issues also? I forgot that I added that also to the machine.

In my opinion yes, but like all things, I think you just have to try removing it and see if the problem goes away.

Very nice workmanship Graham. That is certainly going to be a time piece to be proud of.

Hi Richard,

Make sure that your V bit is actually being held securely in your collet (and that the collet is the correct size for the tool) - It is often the simplest things that cause us the problems.

I have a card at home I can try. Lets hope this works.  Any idea why this causes a problem?

When using an LPT Parallel Port, Mach3 takes control of the Win OS in order to output it's pulse train (step and direction signals) and if the PC has other refresh / update priorities there can be a conflict. Any interruption in this pulse train can lead to lost steps so fitting a graphics card can reduce the loading on the OS.

The definitive explanation is probably a lot more complicated than this but it is more or less the gist of it.

If your new (old) PC has onboard graphics that could cause a problem - fitting a graphics card could be the way to go.

Hi Kooka,

I am inclined to agree with you - dodgy motor.

It happens

Hi Kooka,

You have swapped axis and the problem follows the motor.
Are you saying that this particular stepper motor is the problem or are you saying that the G540 output for the Z axis is the problem ??
