Ed, I am not certain I am interpreting your comment The firmware doesn't apply acceleration limiting, which I regard as a major limitation on performance and dependability correctly, but if you mean that the firmware doesn't do acceleration at all (it is either full speed or not moving), that is

I have been looking at this technology myself and have a machine half built - I found a design via the reprap page which incorporates a milling head as well as an extruder so that, in theory, the parts can be 'finished' in situ after they are made or maybe even as they are being built. I have

I am not a big fan of the various hybrid machines and repstraps (for people unfamiliar with the terminology, a reprap is a printer made from printer parts (REProducing RApid Prototyper), and a RepStrap is a printer made without printed parts (in theory used to make the printed parts for a real
