Tandem Axis doesn't work was created by chili023
I have my first tandem axis setup to configure.
I cannot get the servos to drive together.
Setup as followed
Y1 = Stepgen0 (Joint 1)
Y2 = Stepgen1 (Joint 2)
X = Stepgen2 (Joint 0)
Z = Stepgen3 (Joint 3)
Nether while homing nore while jogging the two servos move together.
I can individually jog joint 1 and 2 but not together. What am I missing? Cannot be much.
I actually feel stupid for asking.
Anyway here are my files

You need for example:
HOME_SEQUENCE = 0 for Z
HOME_SEQUENCE = 1 for X
HOME_SEQUENCE = -2 for both Y
The minus is for the tandem joint !
HOME_SEQUENCE = 0 for Z
HOME_SEQUENCE = 1 for X
HOME_SEQUENCE = -2 for both Y
The minus is for the tandem joint !

You might also need to looks at the signsHOME_SEARCH_VEL = -1.000000 (if you remove the - sign it will search in the opposite direction)
HOME_LATCH_VEL = -0.500000 (as above this is to back off the home switch)
The above seems to me to be very slow commands for the search
