General Mach Discussion / Re: Mach3 controlling Co2 Laser

When you say Post Processor... do u mean V carve Pro ? As that is what i am using to import my 2D DXF files and process them into the cut paths/ Vectors.

Yes, modify the VCarvePro post processor to include the M10P1 /M11P1 codes. (If you have any difficulty doing this then I am sure the guys on the Vectric forum will point you in the right direction).

It all depends on your laser high voltage power unit, perhaps you could post some details of this item.

My PSU has 0 to 5 Volt analogue input for power control and this, internally, incorporates a simple DAC (digital to analogue converter) so it will also accept a 5 Volt PWM (pulse width modulation) signal (0 to 100%). As Mach3 has an inbuilt PWM spindle speed control this can be used. However it does have some problems of periodic variation which may not show when controlling a spindle motor but does show with laser control.
At this stage I would recommend that you get everything up and running by using manual control of the maximum laser current.

The on / off  M10P1 / M11P1 or E1P0 / E1P1 commands are inserted into the GCode by the post-processor used with your CAD/CAM software.

Hi Anant,

I appreciate that you are new to the forum and indeed you are very welcome here but please don't make multiple posting on the same subject.

Hi Anant,

Sorry to make a dumb comment but I am relating to a recent discussion in another thread...

I think that if I had spent a couple of thousand dollars on purchasing Aspire and Artcam I would be reading the manuals to learn how to use them.

Hi Warped,

If it's any help, take a look at my article here http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29 (also the following comments relating to the updates) then, if necessary come back with any questions.

Thanks again Dan.

That led to video showing almost exactly what I want to do  http://www.youtube.com/watch?v=5NFk4Yv_ePc&NR=1&feature=endscreen

Hi Dan,

Thanks, I will do a search and see if I can find it.

I love the effect of the "scrimshaw" look that you get with that. I'm imagining the old oriental carvings or the scenes that sailors on ships would do on ivory teeth/tusks.

Interesting technique indeed!

Hi Dave,

I agree with you, they certainly can look really old world.

Something I want to try is a circular, rotating, panoramic view around a cylinder and since Terry created the Y to A cylindrical mapping screen this project has started to look a whole lot easier to do. I have seen pictures, in old books, where this sort of thing was done on lamp shades but I am thinking more of incorporating it into the base of a lamp. All I need is time
