In order to supply tools to the imsrv spindle, I need to have a mounted rack. Unfortunately I don’t have a ton of room, and don’t want to give up the little that I do have. To get around this, I’ve been working on a articulating arm with a rotating toolholder rack. This will be mounted next to the shertaig, and will swing out when a tool change is requested. I haven’t fully figured out the electronics yet, but I expect it to be driven by an arduino interfaced to the breakout board. More details to come. The picture below is the assembled changer (using prototype plastic parts).
