SCARA vs parallel SCARA
February 18, 2016 10:53AM
Hi! I am develop a scara arm for a printer 3D, but I recently see reprap wally and reprap morgan which are parallel scara, what is the difference between "normal" scara and parallel scara? thanks

... in 'normal Scara' the positioning error accumulates over length -- with the parallel scara design this error is much more reduced and pretty uniform over the complete traveling range ...

single and paralel scara have different kinematics and configuration
both have advantages and disadvantages
you can see the configuration difference in this link [www.wangsamas.com]
