Here is the redesigned horizontal carriage mounted on the frame.
The pace of work is going a bit slower than usual because I am trying to keep the CAD model as clean as possible.
Also, due to Summer vacations in Italy, we might not get the STEP model for the new spindle head before August 20 (HSD seems to be totally off during the first there weeks of August). In the meantime, we'll work on the machine enclosure. Most specifically, I would love to be able to come up with the design suggested earlier: a machine-wide front panel that would go up and down (most likely with two horizontal parts) and two half-depth side panels that would go forward and backward, all three electrically-actuated. Doing so would allow the entire machine to open and close itself, at the push of a button. This is clearly overkill, but I want to give the machine a totally distinctive enclosure, not just cosmetically, but functionally as well.
