I took deivery of a new Shopbot a few months ago and love it...
With one exception; when cutting either tight radius corners, circles or right angles I seem to be getting a lot of "bounce" at the transition between Y and X movements.
I've been able to work around the problem by slowing the feed rates down to a glacial pace, but there must be a better solution short of spending yet more money on the PRT Alpha.
I can actually see the spindle assembly shaking when it makes these moves and all I can attribute it to is excessive flex in the gantry design.
Any suggestions?
