On Thursday 22 November 2012 12:10:26 Pete Matos did opine: > First off Happy Thanksgiving to all of my EMC/linuxCNC friends.

UNFORTUNATELY after several > thousand dollars were spent I had a few more failures of the original > control components and decided to just stop the bleeding here.

These are 130mm 1000 watt 2000 rpm 4nm motors on the > x and y and 6nm on the z axis. I have already purchased a brand new > Intel Atom D525 motherboard, a solid state hard drive 90gb, 4gb ram, a > brand new 15.6" widescreen monitor for the control pendant as well as a > sweet industrial waterproof/debris proof keyboard.

Welcome Pete! AFA pix are concerned, I have used my own page, or pastebin.ca, setting about a week or less expire, then post the link to it that pastebin gives you to here. Stuff I put on my own page tends to not expire & then gets stale. :( > ----------------------------------------------------------------- > ------ Monitor your physical, virtual and cloud infrastructure from a > single web console.
