I just replaced z-trunk and new motor. Ran one project no problem but now I am trying to carve a very basic sign. After about 20 minutes it stops and says "Can't read memory card". So I remove card and re-insert. Again it runs fine for about 15 minutes and now just stopped and appears to have NO power. I checked all power connections and found no problems.
The only thing I can think of is that the temperature in the garage is probably over 105 degrees. Any thoughts??
