It is a long while now since I made any revisions to the plugin.dll but everything was always done and tested assuming the Digital Trigger output would be Active Low. When you are constructing your transistor circuit perhaps bear this in mind.

The latest .dll can be downloaded from here;

Hope this helps,

What software are you using to create your Gcode for laser use ?

No practical experience but they look good.

Hi Fred,

You need to install Mach3 (or already have Mach3 installed) on your new computer before copying over the folder.

Hi,

A laser switched by an active High signal is not a problem.
The LPT Parallel Port (for reasons best known to itself) always starts up with some pins in the High state and some pins in the Low state. For this reason you may need to invert the signal feeding your TIP 120 (or possibly choose a different LPT output Pin) for the laser to always start in the OFF state.
I am not sure what is causing your edge bands but I suspect it relates to the above where the software switches the laser OFF at the start and end of each line and with your active High set-up this turns the laser ON.

Newfangled Solutions Mach3 Wizards / Re: Y axis moving in the wrong direction

« on: October 02, 2019, 01:18:40 AM »

As mentioned in your attached .pdf file - changing the Direction Low Active state of an axis (and saving the changes) will cause that axis to move in the opposite direction.

It is a bit confusing because the correct direction is really the direction the TOOL moves in relation to the work and if you have a moving table then the table has to move in the opposite direction to achieve this.

Hope this helps.
