Is anyone able to identify the kinematics system used in this patent? I can't find any previous discussion on this topic, and the few references I've found say that Stratasys uses h-bot. However it's clear from the drawings that this isn't a simple h-bot configuration. In fact it's not even symmetrical. Is this some kind of modified h-bot to solve the racking problem?

... this is not so far away from my own wire-feeding system, I've designed after a port crane in 1995:

Yes there's definitely some similarities. The biggest difference seems to be motor placement. Do you know what this would be classified as kinematically? Is it some sort of Cartesian variant since x and y each have their own independent motor?

... dunno ... for me this was the simplest design without moving a motor, so could use much heavier+stronger motors than with the common plotters and XY-writers then ...

Figure 4 for the x motion doesn't look feasible. If the motor moves the belt distance dx, pulleys 90 & 96 will attempt to move the carriage dx/4. Meanwhile pulley 102 will try and move the carriage dx/2. Seems like trouble.

would you pay £500 for a used stratasys 1200es?
filament looks a bit pricey, maybe the machine can be modded to take cheaper filaments, & different materials.
