Funny thing is, I had been using the plugin via Output1 active low.  This worked fine and I had been engraving the last couple of days that way.  As soon as I set it to active high it no longer worked.  Go figure.

Hi Greg,

So, is this problem resolved now ??

Hi Greg,

Dan is on the right track.

You mentioned earlier having the Digital Trigger and an Output both configured to the same port and pin and both Enabled at the same time. Conflicts can cause problems such as you are describing and which I am sure you are aware of.

This is exactly why I suggested using two different profiles Raster / Vector.

Hi Keith,

When you configure Mach Ports and Pins / Outputs you can set the Port# to 1 or 2 which then defines if it is your first or second parallel port.

The standard commands M3/M4 - M5  and M7/M8 - M9 would be probably be the easiest to use for switching your relays (that is what they were designed for) then your post- processor just has to insert these commands into your generated GCode at the appropriate place. (have another read through the Mach manual for details etc.). If you prefer to use the CB commands (Activate/Deactivate Signal) then you really need to study the CB manual to establish how CB and GCode can be combined effectively. It would take me forever to explain this properly but 99% of the details you need are in the manual.

Hope this helps.

Hi Greg,

The Impact / Laser plugin uses the Digital Trigger as its output and this can be configured within Mach as Active Hi / Active Lo as necessary.

Tweak: I don't see any G2 or G3 in your tap file. So I have to think that is your first attempt at your bike cutout. I was kind of looking forward to trying out my laser on your fine example of how a cut should look. Thanks for sharing, your a inspiration to all.

Hi Buddy,

This bike was cut from the .tap file I posted earlier.
Incidentally there were no G02 / G03 moves in the code for the second picture in post #576 either.

Thinking totally out of the box....

The torch is loose and at that point in the work the cabling/hose gets tight, moves the torch - when the cabling/hose gets loose again the torch returns to it's correct position.

Hi Greg,

Those bicycles were made some time back and the dxf's are long gone. I did come across this GCode which may be OK for you (scale it to your own requirements).
