I was recently tasked with making a fully automatic worklist maker for the Tecan Freedom Evo I am attempting to test my worklist compatibility and the robot will not initialize out of the blue. It worked perfect last Friday and now it has decided to not work. Whenever I press initialize the robot moves the tips slightly and then the alarm sounds and the initialization fails. None of the tips are stuck any suggestions?

Hi Payton, 

Hope you've already managed to clear the error - if not, I have a few pointers, and can probably give you more with a little more information. 

Let's start with the obvious - have you already power cycled everything? As in, power down the robot, disconnect from circuit, wait to let all caps bleed off, then reconnect and power on. 

Next: are there any error messages? If so, can you share screen shots? 

Also: if possible, open another method - do you get the same behavior? 

Lastly: each of the arms (assuming you have a standard 3-arm config with a RoNa, an MC96 and a LiHa) should be running their own homing routine during initialization - do any of them complete correctly? 

Feel free to DM me if you're still stuck.

Fortunately, I have fixed the error the bioshake drivers were not uploaded correctly and it was causing a freeze of the system.
