Thank you both very much for the replies

I will post a photo of the burned sample soon as I'm not near the machine right now

Tweakie, I downloaded the file where should I put this file ? Is it a script to open in mach 3 ?

As you guys said I would prefer to assign other axis but Z to control the laser and I would prefer a method where I don't have to edit every gcode file I load into mach 3.

Hi Hydrops,

The file I linked is a Vectric post processor - you need to study the Vectric documentation which will tell you how post processors are used to modify the generated Gcode so you do not have to carry out any subsequent editing etc.

Hope this helps.

Hi Vogavt,

A bit more reading for you http://www.machsupport.com/forum/index.php/topic,16446.0.html

I think this explains the construction of the magnet.

If it's any help and to get you started you could use the scrip posted on my webpage here http://www.cooperman.talktalk.net/files/17.htm

Hi Paul,

Looking at your Gcode, the circle comes out at 34mm diameter here.
Perhaps you have your motor steps per unit set incorrectly ??

Excellent work Chris - that looks like it is working just fine for you now.

No script it didn't tell me to put any in

That's most likely to be your problem then.

Do a search for touch probe then choose one of the scripts posted which you think is best suited to your application.

Hi Hydrops,

1) The easiest way is to modify the Vectric post processor to include the M10/M11 commands and remove the Z axis commands. If it's any help to you, one of my modified post processors is here http://hobbymaro.puhasoft.hu/Tweakie/Laser.zip

2) John's PicLaser software allows the choice of axis letter for the laser trigger. With TTL work you just use the axis direction signal and with Greyscale work the actual axis position (either detected electronically with step/direction controlled electronic potentiometer or mechanically with rotary encoder - but there are other options).

3) A stepover of 0.15 to 0.2 mm is usually about right.
