    I would check the tightness of the z axis motor pinion gear. I experienced a similar issue on my older PRT and that was the solution. The loose gear was introducing backlash.

    I just used the same method on my PRT for a move. I did cheat on the trailer portion and used my brother's flat bed tow truck for the move. A motorized winch beats a small come-along any day.

    I really doubt you can get a metal cutting laser for this price range. This is more the lower range for the CO2 laser cutters and engravers that will not touch metal.

    Bill,

    Any chance of seeing the probe run? I'm mainly interested in the 2d profile feature, so that would not take hours of demo like a small 3d probing would.
