Doh!  I just found this sensor which completely eliminates the need for the Arduino.  This provides a stand alone solution for registration mark detection.  Now we can just work on the VB!  This should be easy to wire in as a probe.  Does anyone have some examples of calculating an arc tan in VB and setting the G68 coordinate system rotation from a script?

ATN (arc tangent) is covered in the "Cypress Enable for Mach" manual , page 44

How would i then set the g68?

I'd  provided how to set the g68 in the file that was posted to your other thread.

Call SetOemDro (118,NewAngle)
OEMDRO was added to screen with machscreen. To show me what it was set too. As if it is anything other than zero the Axis X Y DRO's values turn red.

The sensor you used before does not need the Arduino to work, it just needed a 12 volt DC supply, as it incorporated a SPDT relay.
You could then provided the 5 volt source at the relay.
Though it does a poor job of detecting a thin line and lighting the area has to be extremely controlled to be accurate and repeatable.

Using a wide line to get it to work well, makes me suspect its precision at the ability to find the true corner of the scanned probing routine.

i made a camera that finds the registration marks and adjusts for distortion and rotation

Hi guys! Any news on this? Does anyone have a registration system up and running?

because it was for my work and i spent work time i can not give a lot of information.
attached is the script i used for finding the dots and rotating and stretching the file.
hope it is a help
