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.

You could try changing the Step Pulse width in motor tuning and see if that makes any difference to the situation.

Does any one know What email address I should use to request a replacement Darwin license? The license I have is generating Error -37 

Hi Bezalel,

Perhaps best to just use the contact form here http://www.machsupport.com/contact-us/

It's certainly looking good Craig and a wonderful piece of engineering.

Hi Hydrops,

Basically, if your Gcode does not contain any Z axis moves then the Z axis should not move – simple as that really.
Perhaps use a text editor with ‘search and replace’ to delete any Z axis commands from your Gcode??

If you attach a picture, or two, of the excessive burn near the edges of the drawing this may give us a better understanding of the cause of the problem.

Try copying across your modified screen (what ever it is called) .set file.

From just a quick look at the installation instructions E-Stop is configured as Active Low.
To follow their wiring instructions your E-Stop switch should be 'normally open' contacts and only closing the contacts when E-Stop is pressed. Is this the way you have it wired ??

Hi Brad,

1/2" acrylic is just cuttable, albeit rather slowly, with a 40 Watt CO2 laser but an 80 Watt CO2 would be a much better. There is a lot of reading but my laser project is here http://www.machsupport.com/forum/index.php/topic,12444.0.html if it's any help to you.

Hi Brad,

Welcome to the forum and good fortune with your engraving business to come.

The squiggly lines are usually described as 'crop circles' and are related to how arcs have been created in your CAD / CAM (BobCad).

Within Mach3 if you go into Config ; General Config then change the IJ mode that should resolve the problem.

In future your generated Gcode should really include (at the start of the code) a G90.1 (if you arcs are created in Absolute mode) or a G91.1 (if your arcs are created in Incremental mode). The Mach manual describes this in more detail when you get the time
