I've been using my CNC recently to engrave business card holders for my online store. I've added a couple of images, showing how I've managed with the first 60 or so engravings, and to be honest I've had enough and need a better method. (I couldn't attach the images by the way, every time I tried the screen went blank and wouldn't load the images in).
I currently clamp down the front plywood block, insert the business card holder, then clamp the second plywood block to the business card holder at the back. This creates a secure system as it doesn't move at all, but it does require a little bit of setup to make sure everything is square.
Any suggestions would be great, of course I'm able to build something, and willing to put the time into it so I've got a system that enables quick setup without the need to constantly check for square.
