Great news Craig. Pleased you have it working. (the LED is usually off and only comes on when the plate is touched)

To avoid double posting I have added some more information relating to this plugin in this thread, starting here. http://www.machsupport.com/forum/index.php/topic,12444.msg127947.html#msg127947

Hi Craig,

Sounds like you are almost there.
Your current problem seems to be with GND. The cutter should be at the same potential as your USB GND, that way when the cutter contacts the plate the digitize LED illuminates.
The resistor does not go in series with the plate. The resistor just connects your pin 10 to +5 volts, then the plate connects to pin 10 as well.

Hope this helps,

General Mach Discussion / Re: Help with Estimate Program Run Time

« on: May 27, 2011, 02:46:01 AM »

Rhino is calculating the time on the parameters it has set and Mach is calculating the time on the parameters it has set and there is a good chance that the two lots of parameters are not the same.
For example acceleration settings can make a huge difference in the GCode program run time even if the set feedrates between Rhino and Mach are the same.

Show"N"Tell ( Your Machines) / Re: The Laser Project.

« on: May 27, 2011, 02:25:07 AM »

I have been using the Impact / Laser plugin quite a lot recently and one problem cropped up twice (one time too many in my book).
Depending on the image height and the vertical stepover the scan can sometimes finish at the top right of the image. If this final pixel turns the laser on then the work is automatically spoiled when the laser path is draw diagonally back across the work when the head returns to the X0,Y0 origin.

As Art generously made the code ‘open source’ it was time to take a look and I have now added code to always turn the laser off before returning to the origin at the end of the scan and (as belt and braces) altered the return path to X0 then Y0 rather than the diagonal. In addition, I took this opportunity to remove the redundant 40uS runtime check box  and make a couple of alterations to the appearance of the UI.

The modified DLL has been attached just in case anyone else using this plugin has encountered the same problem and needs a solution.

General Mach Discussion / Re: Probe wiring

If you have Probe configured active low and configured to pin 10 and enabled then connecting pin 10 to GND (pins 18 - 20 of the parallel port) will light the Digitize LED.

Perhaps you are not connecting pin 10 to GND (the machine spindle or machine frame may not be GND).
Perhaps what is labeled pin 10 on your BoB is not actually pin 10 (check continuity of wiring).
Perhaps pin 10 on your parallel port has died (try another input pin#).

OK.
Now if you connect pin 10 (probe) to GND the Digitize LED on the Diagnostics page will light. Why would you need any other verification of the operation ?

Are you configuring the input pin# you are using to the Probe input in ports and pins and enabling this input ?
