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.

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).

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.

6. Install Homing and limit switches, and connect to GRBLShield.  This should prevent some crashes.

7. General wiring clean-up and sheathing: some connectors have bare leads exposed, and I'd love to clean up the build by sheathing many of the wires.

8. Label axis, electrical components, etc with a label-maker for ease of understanding.
