Great work Art, the project is all starting to take shape now you are into the actual 'power on' testing stage

This is certainly an excellent project mc.
Thank you for taking the time to post all the details and pictures they are most informative.
I just can't wait for the next installment

So far  I have nothing working.
I guess I need to go back to using the DOS software that it came with.  I cant get Mach3 to do anything.  $175 down the toilet...

Are you really going to quit that easily ?? 

I certainly wouldn't - many things beat me for a while but I always get the better of them in the end (particularly if I have spent $175)

Hi Jan,

Your trigger circuit looks fine and that is a very nice screen set you have produced 
Unfortunately, the plugin will only support parallel port operation at this time

Well spotted Krypton - you are quite correct - only the unused inputs should be tied to GND.

Just a suggestion and perhaps the first thing to check - go into Win. Device manager and check the address of your LPT port then check you have entered this address into Mach3 / Config / Ports and pins for Port #1 and that the port is enabled.

Running the Impact / Laser engraver takes much of the system resource so displaying the picture during operation would perhaps not be practical.
There are a number of different programs that will produce similar results. DotG comes to mind and this can be found here http://dotg.weebly.com/download.html
The start-up menu for the Impact / Laser plugin is written within the source code so you will not be able to make a translation of that part easily.
The electro-magnet Andrea and I have been using can, I think, still be obtained from him - check out his website or possibly drop him a line http://www.robotfactory.it/
I have never really thought about THC and engraving non-flat surfaces but that sounds like an excellent idea to me.

I have a crazy Idea on etching tombstones on it's site,I would go with a generator and a small machine that could be placed directly on the granite or mable.

Brilliant - there are a number of professionally made machines that do this task but they are not at all complicated so I think you could easily better their performance and design. 

The problem with SSR's is that they only switch at the 'zero crossing point' of the a.c. waveform so switching speed is limited to the frequency of the a.c. (here in the UK it is 50Hz and that is not really fast enough to be of any use).

Hi Jan,

I think that is one of those things you will just have to ‘try it and see’.

Basically, physics limits the speed in relation to the mass of the moving parts but I am certain we have not yet come up with the best possible design so I would be most interested in hearing the results of your experimentation.

Hi GC,

In Config. / Gereral Config. change your IJ Mode.

Ideally you generated Gcode should include (at the beginning of the file) the G90.1 if your circles have been drawn in Absolute Mode or G91.1 if they have been drawn in Incremental Mode.
