five-bar / parallel-scara kinematic was created by wasweißdenichschon
hi,
my name is Tim i am new here like many others before.... My question may is asked already 100 or more times.
Is there already a five-bar kinematic for linuxcnc or an kinematic which can used for it?
For hours i tried to figure it out but with no result only a video on youtube but with no description.
Thank you very much for your help.

You mean this one?
The video says that the kinematics has been added to LinuxCNC.
And Pentakins is here: github.com/LinuxCNC/linuxcnc/tree/master/src/emc/kinematics
There is some very basic docs here, look for "pentakins"
linuxcnc.org/docs/stable/html/man/man9/kins.9.html

Probably this one:
As far as I am aware there is no simulation config for this but I found this paper that might help you write your own kinematic:

There is a sim config, it's even in 2.8.
sim-axis-pentapod.
github.com/LinuxCNC/linuxcnc/tree/2.8/configs/sim/axis/pentapod
Though there isn't a Vismach model, so I don't know how helpful the config is to understanding the kins.

Yes, there is a sim-config for 'pentapod' but not for 'five-bar / parallel scara'.
At least as far as I know.
Note, a 'pentapod' uses 5 motors while a 'five-bar / parallel scara' only uses two.
