Rotrics Dexarm several problems

I have several problems, anybody who knows the rotricsDexarm very well? First: after trying to update the firmware of the touchscreen ther are 3 dark lines on the screen, nothing else. So what happend and what can I do?
2nd: how can I teach the dexarm the movements without an record- knob in the rotric - studio-programm? In the touchscreen there ist a record knob and very easy to show hiim what he has to do…

Hi @cyberspider and welcome to the forum.

I haven’t used this robotic arm, but did you purchased it from RobotShop?

Also, did you try contacting Rotrics support?
