Can Llithophanes be produced with a laser ??

The answer is definitely “yes” but not, I suspect, with the same degree of quality as produced by spindle machining.

I had to give it a try and this was my first attempt. It is not that good but I am sure the results could be improved once I have discovered the reason for the unwanted background ‘noise’ which is spoiling the effect.

Has anyone else here tried creating Lithophanes using a laser ??

Excellent work John, I am pleased to hear that you have your new electronics, for the laser power control, all up and running – there will be no stopping you now. 

(For others following this thread who may be interested in using diode lasers with Mach3 there are some more pictures and discussion on the techniques, hardware, development and progress in this thread http://hobbycncart.com/forum/63-151-8 )

Excellent work Keith, I look forward to seeing some of the foam cuts.

This question has been raised before and Hood posted the link to some further MaxNC (and other) information; ftp://machsupport.com/ExtraInformation/

If you check out the documents relating to MaxNC you will find one mentions using LPT Pin12 as the home switches input etc.

Thanks Terry, I'm up to speed on that one - the reset scale function has already been added to my Return Mach3 to Normal button.

Hi Zig,

Good to hear that your machine is coming along well.

No problem with the Phlatboys code from Sketch-up here so I am not sure what it is that you are doing wrong.

Scale Button and the X & Y max. DRO's duly added. 

Excellent thought Terry.

Many thanks.

A BIG "Thank You" to OzzieII for the original idea and BR549 for all the work he has done on this screen / wizard.

I had to move around some of the components to avoid conflict with my global screen items but this has now been added as a page to my standard Mach3 screen 1024.set

This method is so quick and easy to use, with existing tool-path files, it is just amazing and once again, thank you TP.

As Ray has said.

Just as a general method the Velocity and acceleration are increased, in stages, until the motor stalls (squeals) then the settings are reduced by at least 30% (sometimes by as much as 50%).
