| + | 9.8.2016 - Danny Blanchard: Drag chain bracket installed, new lock washers installed (machine can now travel freely until it crashes... :). GRBL shield and Arduino Uno were removed and bent/disconnected pins repaired (likely due to rough handling?). E-stop switch backing nut tightened. Machine ran fine on Easel and with GRBL Controller. |

| 9.7.2016 - Danny Blanchard: Machine cleaned, belts tensioned, power supplies temporarily mounted to wall, wires organized and secured with zip ties. Spindle control and E-Stops tested, both working. | | 9.7.2016 - Danny Blanchard: Machine cleaned, belts tensioned, power supplies temporarily mounted to wall, wires organized and secured with zip ties.

| 1. Waste board repaired or replaced. Entire board is unsupported in the middle, causing it to sag. Also, one stud has pulled up a volcano-like mountain in one part of the waste board, and needs to be milled down. Recommend getting two $7 20mmx20mmx300mm extrusions (from Inventables or elsewhere) and T-nuts to support it in the middle (this is a common upgrade for this particular machine). | | 1.

− | 2. Y-axis cable/energy chain is too short, binding before the gantry can reach Y-zero. I have two brackets I'm going to install that will relocated the chain about 1 inch, and this will do the trick (found this solution online from another SO2 user). | + | 2. Bearing blocks on all axis need to be tuned. Some are not making contact, and gantry is not square to waste board. |

− | 4. E-stop case is glued shut, but the nut on the back of the switch has backed off. I'm going to drill a small hole parallel to the nut to allow manual tightening without having to break open this nice case. Case should be permanently mounted in an easy-access location on the frame.

− | 5. Spindle PWM, both power supplies, and perhaps the GRBLShield should be mounted in a compact, fan-cooled enclosure. I'd love said enclosure to be part of a full machine enclosure that incorporates noise suppression, interior lighting, and dust collection.
