It's a process as I outlined in my last post.

Attached is a .png graphic which was converted to a .dxf and then an engraving toolpath (Gcode) created using Vectric.

Some laptops work just fine with Mach3 and the parallel port but most do not - I think you have one of those which does not work that well with the PP  :'(

It's for this reason that laptops are not supported for parallel port operation, only for use with an external motion controller.

This is an example of what I think you want to achieve...

Initially a logo is found which is close to the required size (internet search).
The logo is then converted to a .dxf and scaled to the desired size (cad software).
A Gcode toolpath is generated from the .dxf (cam software).

Sorry to say but that would not be ideal.

It has a background size of 23.8 x 13.2 mm and when scaled up to the required 90 x 50 mm has such poor resolution that it would be unlikely to yield any i and j arcs.

Try to find something of the correct size and of a good resolution.

(You could use a CAD software to create a border 90 x 50 mm then perhaps insert some text with a font that contains arcs - the easiest solution perhaps).

You have to do some of the work yourself - I have no intention of doing it all.

1) Find (or design) a logo of the correct size, containing the required arcs (.bmp would be OK but .dxf preferred).
2) Use the full reply and additional options tabs to post your logo here.

I will convert it into a dxf and produce an engraving toolpath Gcode then post both here for you.

Post a dxf of the logo you require (highest resolution would be best).

Hi Bernd,

I can't say for certain but there does not appear to be any mistake with your wiring.

Obviously you need to set the PWM signal near maximum, the potentiometer to around 10%, turn on the spindle (M3) and apply the M11P1 command.

Sorry to say this but the Port 1 Pins Current State is not a reliable indication. I think it must have a mind all it's own because it used to work well on my setup now it does not work at all.

If you are using XP then perhaps download and run Parmon http://www.geekhideout.com/parmon.shtml this will run in the background and indicate the PP pin states.
There are also other parallel port monitors available - internet search perhaps.

Perhaps you can help me with something else. I'm new at this and have run into a bit of a snag. In order to initialize the machine, I can see how you can use G28 or Reference to set Mach3 to home. However, if the home position has been lost, then it is  required that you disengage the physical drives after moving manually to home, and then use G28, etc. Is there any way you can set values in the machine coordinate DRO's? As far as I can see, you can't zero the DRO's  or enter values from the keyboard.

Someone else will have to help with this question as I have never used G28 or any homing routines, sorry.

You are not going to feel stupid at all.

One way you can display the B (or C) axis on the main screen is to use a screen editor and add the B (or C) axis DRO or alternately download and use one of the 6 axis screensets from here; http://www.machsupport.com/software/downloads-updates/screensets/
