Currently in bits and I can't manage to put it together: https://twitter.com/goatchurch/status/996707935576383489 Hopefully @Clayton_tom can come Monday and help out, and @magman2112 says he can advise on how to make it tidy.

Get it to work in any form

  • Check Beaglebone works (ssh -X machinekit@10.0.29.153)
  • Get enough wires connected to run Beaglebone from plug-in power supply
  • Check the table servo can be removed and refitted
  • Replace the table servo encoder which was broken because servo wasn't removed
  • Fit arm servo and belt drive
  • Check fitting of the Z-axis is aligned and the spindle driver can be powered
  • Wire up all the end stops and switches

Make portable and tidy the electronics

  • Fix wheels to the 3 corners
  • Make a CAD design of the space below and cut a diagonal shelter
  • Use cut-off signal on spindle driver instead of cutting power for Estop
  • New housing configuration for drivers, power supply and loose wires

Operating procedures

  • Re-install the Beaglebone firmware and document the settings.
  • Does new machinekit firmware have PRU and quadrature encoder access for Tosca experiments?
  • Produce an all-in-one automated calibration sequence (run scipy on the BB)
  • Cut useful HG parts (swan neck and sprog end)
  • Take the machine somewhere else to cut its parts.

@magman2112 has ordered a suitable enclosure to fit all the hardware electronics. (cash for £30, though needs a bit more change)

I should order one or two of these: http://uk.farnell.com/geckodrive/g320x/dc-servo-drive-18-80vdc/dp/2811538
