Got a bit further on my printer build. Mounted the electronics on a pegboard, attached to the back of the printer frame. The entire assembly is easily removed. Made mounts to attach the electronics to the pegboard - easy to rearrange.
Must admit - inspired by a movie. In the original Matrix movie (1999), a scene is set in the “wet wall” of a building. The notion of putting all the plumbing on one wall, with interior space for room for a workman - makes a lot of sense. In this case, putting all the electronics on one base - easily dis/mounted - also makes a lot of sense.
The 24V power supply is connected to AC via a standard fused switch, with the usual sort of detachable cord. A small 5V power board powers the two control boards. The RADDS board will take 24V power, when installed.
The UPS is meant to be a used with the final printer. Since most power outages tend to be short-lived, better to continue printing, rather than doing a clever shutdown (as Prusa’s new i3 mk3).
Need to get a bit further on the software. Iterating on the Raspbian configuration. Meant to be accessed via SSH, so disabled the GUI. The Android Due is as yet not configured.
Also need to setup the RADDS board that will sit on the Due. My dubious soldering skills will be employed to solder headers on the Trinamic drivers.
Still lots to do…
