3040 Aluminum HDF Spoilboard for 3018 CNC Extension Kit

Increases working area

First I would say the product is well worth it and significantly increases working space. The product arrived quickly and was relatively easy to install. However, there some shortcomings that you should be aware of. At two points in the instructions there are contradictions. The position of the Nut Seat is shown close to and further away from the Y-axis stepper motor. The "Slider" is shown as the nut and the bearing. Not sure what to call it. The screws holding the slide bearings are slightly short when the spacers are installed. There's some fiddling that has to happen to make them engage with the nut. The extension kit say to place the gantry 60-80 mm from the back face but this kit says 120 mm. The latter is closer to correct. Not all the full surface is available because of the limit switches. You lose about 25-30 mm. Max travel is about 315 mm. The biggest drawback is z-axis space. It's reported you lose 9 mm with the lower spoilboard. There is an optional upper spoilboard but it's 15 mm thick. I used some 1/4" MDF and blue tape with superglue.
