Problem with Mach3 Camera Plugin?

(1/3) > >>

Hello,

I am turning here for help because I have seen that Klaus frequents this board and I'm hoping he can help.

After reading Tweakie's old thread here http://www.machsupport.com/forum/index.php/topic,22932.0.html I was inspired to set up this same capability on my father-in-law's machine.  I purchased a USB camera similar to the one used by Tweakie, modified my Mach3 screen to add the buttons (thanks Klaus for Machscreen and Tweakie for the code) and installed the latest version of Klaus's camera plugin (v 3.04).  When it works, it works beautifully allowing me to quickly find X0 Y0.  However, the camera plugin seems to have some difficulty with my system as the camera view window "freezes" frequently which requires me to terminate and re-open the window to continue.  I have done a bit of testing with the camera feeding other video windows (Window media and ISpy) and the image never has an issue so I believe that it is something to do with the camera plugin.  I have tried two different cameras and both operate normally with other software but "freeze" (sometimes immediately) with the camera plugin.

The computer is running Windows 7, 64bit and my Mach3 version is 3.043.062.  When the camera view "freezes" I am also unable to toggle the interrupted crosshairs but I can select the Dialog Settings and Terminate buttons. 

I hope that I can get this issue resolved because this capability makes accurate part setup much easier for him.

Thank you in advance for any help you can provide.

Regards,

Steve

Hi Steve,

I have never used Win7, 64bit so have absolutely no idea what could be causing the problem but I am pretty sure Klaus will know.

Hi Steve

did you try the camera on different USB connectors? With help of USBDeview" (Freeware) you can find out, whether other devices are connected to same internal hub as your camera.

Klaus,

Yes, the camera was tried on at least two USB 2 ports and one USB 3.0 port with no difference in behavior.  I will get USBDeview and see what it tells me about the configuration and then report back.

Thank you,

Steve

Klaus,

I have used USBDeview as suggested and discovered no obvious conflicts.  There were two other USB video device drivers, not in use, from previous webcam installs which I removed using the tool, however, the behavior did not change.  I also, for completeness, disconnected another camera that is on the system and used for general monitoring with another application, and tried again.  As has become the expectation, the video plugin window froze almost immediately upon opening.  Do you have any other experiments or suggestions?

Thank you,

Steve
