Thank you,

During recent work, using the Mach3 Impact / Laser Engraving plugin when engraving photographic images into wood it became apparent that in order to reproduce the lighter shades the required laser output power was burning too deeply into the darker portions and loosing some of the detail present in these areas.

To offset this problem I have made a small change to the plugin’s .dll to incorporate a user selectable Greyscale Compression feature the function of which is shown in the following picture. This function essentially alters the ratio of output pulses in relation to pixel value so that a different balance is achieved over the total range of values with the density of the low value pixels increased thus allowing laser output power to be reduced and create improved detail within the high value pixel areas of the work.

I hope this change may be useful to others using the plugin and the latest version of the .dll and it’s associated .pdf document can be downloaded from here;

Although there are still only a handful of us worldwide that are using the Mach3 Impact / Laser Engraving plugin I thought you may all be interested in the latest update.

Because the output from the plugin is bi-directional, the exact registration of the horizontal lines produced is dependant on device activation speed and from version 1.1 to date this line registration had been set to a compromise between the speed of a laser trigger and the speed of an impact magnet trigger.

Arising out of necessity, I have recently had to adjust this line timing to better reproduce some fine detail work with Lithophanes and in order to preserve the plugin’s compatibility between Laser and Magnet operation I thought it would be wise to include a user adjustable horizontal alignment feature.
To this end I have now added a group of 4 buttons to the GUI - these new buttons will allow the registration of the raster lines to be advanced by +1 or retarded by up to -2 image pixel widths (with the default being zero) and this should now be sufficient adjustment to cater for the correct operation of both devices.

I still have a bit of tidying-up to do (I always seem to get into a terrible mess between the manual coding and the automatic coding from the wizards when using Microsoft’s Visual C++), and I need to do some more testing but the latest version of the plugin (1.2c) will shortly be freely available to any that are interested.
