The first time went very smoothly, except that the length of the back was 1/8 of an inch short. The wobble from the only partially-tightened bearing rails cause this. Every other axis didn't have this issue.
To compensate for the 1/8 inch, I made the gantry CAD file 1/8 of an inch longer and updated the tool paths. After I installed the new back I would re-tighten all the axis to remove the wobble.
The second time was going along fine until... everything shut down. I opened the shed door to find everything shut off and the gantry stuck on a cable. The motor shaft caught onto the power cable of the overhead lamp and cut through the insulation. This caused a short circuit that blew the surge protector in the extension socket (I couldn't reset it anymore). I was just relieved that all the expensive electronics survived.
Uh oh. |
After cleaning up the dust and fixing the lamp cord, we began cutting the back for the third time. This went off without a hitch and we were able to install the new back.

Today was definitely a day of learning and a warning to pay more attention to the machine. The torque of the motors aren't meant to be joked with.
I just need to tighten up all the bearing pipes and create a dust boot with vacuum attachment for the router. The dust is really getting out of hand.
