    Bob’s Build Log (Seattle)

    in Robot Builds

    Nothing exhaustive but I’ll try to include useful stuff as well as general progress.


    Most of the 3d printed parts ... not sure I like the colors but it was the least offensive of the filament I had sitting around

    Most of the 3d printed parts were done on my Makergear 2. It did them without any issues, which was nice.

    I started printing things on a Formlabs Form 3 but it’s work volume is too small for the bigger pieces and it is kind of overkill. I did print a few things, such as the controller mounting box:

    OK, it is driving me nuts that this blog is rotating my pictures but provides, at least on my iPad, any means to rotate them into a reasonable orientation (as far as I can figure out). Sorry for the sloppy posts.

    I found it very handy to store parts in an orderly way as I do the build. These cases are nice because the storage bins are removable boxes:

    Third axis and wiring for J1, J2, and J3 almost done. Waiting for some keystock before greasing and covering up the chain drive.

    I got frustrated with the 3mm linear bearing rails. I could not correct them to a uniform thickness. I ordered some linear rail stock from McMaster Carr. Hopefully, that will be less frustrating.

    Stuck in the house because of Covid-19 (I don’t have it yet but Seattle is shut down). Basically done with the control box

    Robot mechanical all complete, control box, and cables built. Next step firing it up. I’ll spend a bunch of time checking things ... hopefully, movement in a few days.
