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.

Tweakie.

Tweakie, is this file for aspire ?

I put it in PP folder and when I try to choose it in aspire it's not showing, and I also notice there's no other file there with the .pst extension

So, if I understand right PEP will only work with Z axis for laser control, is that it?

I will read the pdf now.

regarding the fan I already brught with the kit, in fact it's got 2, one for the laser and one for the laser circuit board.

Can the M10/M11 commands that Tweakie refered to be implemented with PEP and do you have a tutorial explaining how to do it ?

Thank you very much

Sorry for dumb question but what is TTL  ?

Jeff, do you have a link where I can read more about the variable feedrate ? Regarding the heatsink I have the mist hose installed on the machine which can also spray air only, can this be used to cool the diode ?

And by what I understand in PEP it is easy to assign other axis than Z, is this correct ?

Thank you for your patience, I'm having quite a hard time understanding and getting this stright

Hi Tweakie,

thank you very much for replying

I use vectric aspire, is there any way I can do this besides deleting all z commands ?

I am considering buying pic engrave pro laser, do you know if this progam eliminates the z commands, which I thought it would but just to be sure.

I would prefer a program that I don't have to do text editing

Regarding the photos of the excesive burn, I will take some later and post here.

Just to have an idea, what stepover should I be doing for laser engraving ? In this case I created a tool in aspire with .2mm for the laser

Reposting here hoping somone can help me

Hi

I have a problem with the configuration of mach 3 and laser.

CNC Machine is a heiz 720T, this http://goo.gl/z2THoM laser kit is from J Tech Photonics using latest version of mach 3

I have managed to get it working with the db25 dual breakout board connecting pin 17 and 25 to laser board and making output to #3 and M3 Command on mach and creating a new profile in mach 3 for laser

My doubts are :

How can I stop the Z axis from moving without disabling it in ports config in mach 3 ?

After testing the laser I notice that it is burning too much especially near the edges of the drawing is there some setting to correct this ? I have tried to increase height and speed but problem remains.

Can someone please help me ?

Thank you
