I haven't used a pendant, but I don't see myself using one single handed. I would probably make a few points around the machine to mount the pendant where I can reach it, but keep my eye on what's going on. That's why I think the feel of the detent feedback is important. I would look to the major CNC machine makers for insight on this. They have decades of experience and have weeded out any of the fancy stuff that doesn't get used in the long run. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
